THE RESULTS OF GRAVIMETRIC MONITORING ON THE WORKED-OUT POTASSIUM SALT DEPOSIT IN THE PRECARPATHIAN REGION
Authors S.G. Anikeyev, E.D. Kuzmenko, S.M. Bagriy, B.B. Hablovskyi and U.O. DzobaSummaryThe formation of karst cavities, the disintegration of inter-chamber pillars, deformation of the earth surface and inrush of oversaline water into the underground voids, which is especially dangerous within the settlements and industrial complexes, are the results of mining operations and poor mine conservation (by filling the waste space with the salt brines) in the areas of the Kalush-Holyn potassium salt deposit. The geological and geophysical control of the ecological and geological situation at the mines is performed by using the high-precision gravity exploration. The efficiency of gravity method is investigated in the paper and the results of high-precision gravimetric monitoring of the geological environment state at the division of the Skhidna-Holyn mine field at the Novo-Holyn mine are given. This mine is located on the territory of the Precarpathian fore deep. The modelling of changes in the density structure of the geological profile of the mine, i. e. prediction of the integrity destruction of the saline rocks and the salt table, was performed by solving the gravity inverse according to the space-time anomalies of the gravity field.

CREATION OF ENVIRONMENTAL MONITORING SYSTEM ON THE BASIS OF GEOINFORMATION PLATFORM
Authors O.P. Fedchenko, I.V. Tolok, I.K. Syniavska, I.V. Pampukha and R.V. PysarenkoSummaryThe ongoing change of atmosphere and environmental parameters of Earth inflicted by anthropogenic load, as well as by industrial and military objects requires reliable evaluation of the ecological situation and its anticipation with a view to provide ecological security. This process entails forecasting of further favorable conditions or negative outcomes development and decision-making based on ecological monitoring through environmental monitoring automatized systems (decision-support systems).
Notably, all above mentioned environmental and anthropogenic components are linked with a unique component such as the dimensional factor (geographical location). As we know, the best tool to process spatial data is Geographic Information System (therefrom — GIS). The modern full-functional GIS platform allows not only to set up the geographic information system of any scale and designation, but also to develop the efficient system of ecological monitoring unified with the decision-support system. At the same time, it should include the following data array: air pollution, hydrosphere pollution, land pollution, technogenic pollution, vegetation cover, as well as public health.

Authors H.H. Guliyev, G.M. Efendiyev, K.K. Aghayeva and I.A. PiriverdiyevSummaryA methodology of assessing the stress state of the considered section of the geological medium is offered in this report which allows carrying out a predicted risk assessment in zones of earthquakes based on the analysis of geological data, measurements of local magnitudes in the array and geomechanical modeling. As a result of the study of complex nonlinear systems in the literature scenarios of the occurrence of natural disasters appeared, which are based on a change in the stress-strain state of the rock mass. It allows establishing the causes of catastrophic events, in particular, earthquakes in some cases. Risk management is based on it. Finally, risk management should ensure the safe and stable operation of the enterprise, the safety of the population in the considered territory. The data of monitoring of local magnitudes and results of calculations of stress in the rock mass are used while calculating and analyzing risks.

PROGNOSTIC MODEL OF MINERAL RESOURCES DEVELOPMENT IN UKRAINE
Authors L. Horoshkova, V. Volkov and Ie. KhlobystovSummaryThe work develops a systematic approach to the management of mining, using, export and import non-metallic minerals for construction considering the economic parameters of the development of the world market situation, the domestic market and the resource component of state security. It is proved that it is possible to solve the problem of lean use of minerals by more balanced extraction of minerals, namely, establishing a correlation between extraction and use volumes. To predict the development of the industry, it is suggested to use the author’s multifactorial economic and mathematical model for forecasting the development of complex systems. It is proved that such a model will allow controlling the volumes of mining of technologically related minerals in interdependence on the volumes of their use. An analysis of dynamics and geographic structure of export-import operations was also conducted with natural sand, pebbles, gravel and breakstone. The obtained results allowed us to conclude that the approach to formation of export minerals’ flows is not rational, because it poses a threat to the financial state of the mining industry and the country.

POTENTIAL OF MINING WASTE RECYCLING IN UKRAINE
Authors O. Hrinchenko and O. YushinSummaryMost industrialized advanced countries of the world place high emphasis on utilization of mining wastes. In Ukraine, rate of waste recycling still remains rather low. All the industrial wastes of Ukraine can be classified into four main groups which differ on amount of accumulated materials, hazardous rate and valuable components present. Mining enterprises of Ukraine produce two types of wastes – overburden rocks accumulated in dumps and slimes stored in tailing ponds.
Kryvyi Rih iron ore basin of Ukraine may be taken as a typical example, where 10 to 13 bln tons of overburden rocks are accumulated in dumps. The dumps include about 50 useful minerals and rocks that might be recycled. Unlike dumps placer deposits can be formed in tailing pond. there are several types of technogenic placers that can be worked out in Ukraine: (1) iron ore tailings (500 mln tons) to be recycled on iron and gold (up to 4 g/t); mangane ore tailings (150 mln tons); (3) alumina red slimes (1,2–1,3 mln tons) that include gold, zircon and rutile grains; (4) tailings of titanium ores to be recycled on gold (5–6 g/t); (5) tailings of kaoline that might be recycled on monazite concentrate (lanthanides and thorium).”

THE MAIN APPROACHES OF LANDSLIDES CLASSIFICATION AND MODELING OF THEIR IMPACT ON INFRASTRUCTURE
Authors O. Ivanik, V. Shevchuk, M. Lavrenyuk and D. KravchenkoSummaryThe basic principles and main approached of landslides classification and modeling of landslide hazards have been proposed. Developed classification of landslides is used to create geological, physical and mathematical models of landslide slopes and subsequent development of tools to assess the stability of slopes. Modeling of landslide hazards include combination of stochastic and deterministic approaches. The application of stochastic methods allows to evaluate the complex factors of landslides and define their priority. Deterministic modeling of landslides makes it possible to perform a quantitative assessment of the impact of some factors on the landslides formation. It is proved that the stress-strain state of the rock mass is the one of the important criteria for the evaluating of the slope stability. Formulation of the task of stress-stain assessment and formalization of the calculations for the landslide slopes with variable parameters of the water saturation has been proposed. A numerical-analytical algorithm for solving the problem in the mathematical formulation, which is based on a modified iterative boundary element method, is developed. This technique is used for the landslide hazard assessment in different areas.

DEVELOPMENT A PERMEABLE REACTIVE BARRIER FOR IMPROVEMENT OF ECOLOGY STATUS OF ZHOVTY VODY CITY
Authors B. Kornilovych, L. Spasonova, I. Kovalchuk and Y. KoshykSummaryThe development of mining and processing industries in Ukraine has increased the risk of negative impact on environment. One of the most complicated environment situations in Ukraine is the Kryvyi Rig basin, where iron ore and uranium are mined at numerous quarries. A variety of methods have been proposed for remediating water, soil and sediments. A relatively new (in Eastern Europe) in-situ method is a permeable reactive barrier (PRB) that is constructed in the subsurface to intercept and treat contaminated groundwater. One of the most promising substrate materials for PRBs is zero-valent iron which has been extensively studied in recent years. Biological treatment using PRB technology is also very promising. PRB technology employing zerovalent iron which combines subsurface fluid-flow management with contaminant treatment by biogeochemical processes are also very perspective. Batch and column experiments provided with real contaminated ground water from Zhovty Vody site show the potential for zero valent iron based remediation technologies in effective removing of uranium. Also, the provided biological experiments showed possibility for the indigenous cultures of bacteria from Zhovty Vody city to reduce U(VI) under anaerobic conditions. The results obtained proved the acceptable potential of this indigenous consortium for bioremoval of uranium from contaminated groundwater.

RECONSTRUCTION OF PALEO STRESS FIELDS ON HUAI KHOK GOLD DEPOSIT (LAOS)
Authors D. Kravchenko, A. Drozdova and R. ChaikaSummaryBased on results of the analysis of cleavage, fracturing and shatter zones the parageneses, characteristic by steep dextral and sinistral shear zones with normal faulting components was clearly determined. We marked at least two shear zones that are likely conjugated zones and generated in a higher-order stress field. These shear zones are generated in the conditions of prevailing stresses in the north-east direction with an average plunge of σ1 about 20°. The most probable areas where landslides can develop are mountain slopes with trending coincident with the strike of shear zones and with bisectional sub vertical plane between them.

Authors T. Kril and S. ShekhunovaSummaryThe purpose of this work is to establish the dynamics of the terrain elevation changes in time as a component of geo-environmental monitoring basing on radar satellite images interpretation. Research has been performed for the territory of the right-bank slopes of the Dnipro River in Kyiv. There are proposed a method of the establishing of terrain elevation changes which build on the construction of a base point network for all satellite images, interpretation of the results taking into account seasonality and gradation ∆h in accordance with the elevation discreteness of the images that have been used. Analysis of a images series from December 2007 to January 2009 made it possible to identify stable areas within the research territory and those where the fluctuations of elevations (rising and lowering) have been observed. Terrain elevation changes in unstable areas are explained according to the engineering-geological conditions and technogenic development of the researched area. Distinguished trends based on ∆h of surface revealed a correlation with the location of a extended fault system and other lineaments of this territory. Comparison of long-term observations of terrain elevation changes will allow to identify and classify the lineament forms, in particular those that affect the slopes stability.

Authors E.D. Kuzmenko, S.M. Bagriy, U.O. Dzoba, V.V. Kostiv and V.Yu. MaksymchukSummaryThe report is devoted to the study of rock masses deformation problem in the salt mining areas. The results of geodetic and geophysical researches, carried out in 2017–2018 on the Khotin field area of the Kalush salt mine, are presented in the paper. Geodetic surveys were performed on five profile lines using the method of high-precision geodetic leveling. Geophysical electrical explorations have been conducted by two methods – TDEM sounding (time-domain electromagnetic sounding) and by the natural electrical field method. The obtained results made it possible to estimate the rock masses state, to determine the inter-chamber pillars deformation degree of the Khotin mine field. The mathematical modelling of the stress state was carried out taking into account the presence of a specific object of high risk – the gas pipeline, which resulted in predictive models of the earth’s surface subsidence in the studied territory.

MODELLING OF THE LATE PLEISTOCENE CLIMATIC CHANGES IN THE BUKOVYNA AREA BASED ON QUANTITATIVE RECONSTRUCTION METHODOLOGIES AND PALYNOLOGICAL DATA FROM GEOARCHAEOLOGICAL SITES
Authors Ye. Rohozin, T. Yurchenko and N. GerasimenkoSummaryThe paper presents quantitative palaeoclimate reconstructions for the short-term phases within the main Late Pleistocene stages, based on the combined application to pollen data of two methods: informational-statistical (Klimanov et al., 1995) and ‘the best modern analogues’ (Guiot et al., 1989). The study area is Bukovyna where four geoarchaeological sites were palynologically studied and interpreted in palaeoclimatic sense. The standard errors for the calculated values are 1.3°C for mean annual temperatures, 1.6°C for mean July temperatures and 100 mm for annual precipitation rates. The results demonstrate cyclicity in climatic parameters changes through the Late Pleistocene and the large amplitudes of these changes. High-resolution sampling of late pleniglacial deposits has shown millennial- and even centennial-scale oscillations, which indicate the possibility of very drastic climatic events. Crucial changes resulted in environmental hazards, which affected the settlement patterns of Upper Paleolithic population. The amplitudes between cool and warm phases within the last interglacial (the analogue of the Holocene, the current interglacial) also were large and, thus, could cause climatic hazards. The reliable knowledge on the regular pattern of past climatic changes is crucially important for understanding of their nature and, thus, possible forecasting of climatological hazards.

GEOGRAPHIC INFORMATION SYSTEMS IN GEOLOGICAL MONITORING DURING THE CONSTRUCTION OF URBAN UNDERGROUND STRUCTURES
Authors E. Kulikova and A. IvannikovSummaryReduction and prevention of environmental hazards in underground construction is based on the account of all levels of mining and construction production, from the stage of obtaining the geological information, forecasting, modelling, drafting of construction and ending with the choice of effective measures of engineering environmental protection during the operation of facilities. The environmental strategy also includes the study of the dynamics of development in space and in time of the artificially formed ecological system “underground object - rock mass - environment”, i.e. geomonitoring. One of the factors that need to be taken into account during the development of underground space is the impact of underground structures in the process of their construction and operation on the environment, when the natural stress-strain state of the rock mass and its inherent engineering-geological and hydrogeological conditions can significantly change. It is the multifactorial interaction of the underground structure and the environment that makes it necessary to have constant geological monitoring of the underground space at all stages of the life cycle of the structure. The article deals with the use of geographic information systems for the analysis of both current and long-term consequences of the development of underground space in the city.

GEODYNAMIC CONDITIONS OF NATURAL HAZARDS WITHIN MIDDLE DNIEPER REGION (BASED ON STRUCTURAL-MORPHOMETRIC ANALYSIS)
Authors V.V. Shevchuk, O.M. Ivanik and L.V. TustanovskaSummaryUkraine is characterized by active natural hazards processes within different structural and tectonic and landscape-climatic zones. Within the Middle Dnieper Region, the gravitational processes are most widespread. The determining factors of these processes are lithologic and stratigraphic conditions; hydrogeological regime; structural and textural features of rocks; geomorphology of slopes. The second category of factors includes dynamic processes, erosion, weathering, tectonic regime of the area, and anthropogenic impacts. The basis of studies is the structural-morphometric method. Structural morphometry, aimed at investigation of various tectonic structures and vertical movements of the earth’s crust, is the tool to identify the genetic relation between geomorphological and tectonic processes. As a result of the structural-morphometric studies, a number of morphometric models and maps have been built. The most informative from the natural hazards forecasting point of view are the maps of residual relief. On the basis of comprehensive geological-geomorphologic studies, the influence of tectonic movements and exogenous geological factors on the development of natural hazards within the Middle Dnieper Region has been determined. According to the data of structural-morphometric analysis, local structures have been allocated, which are characterized by the formation and activation of hazardous geological processes. They are located mostly at the right steep slope of Dnieper River. Created models are the basis for forecasting of hazardous geological processes.

MONITORING OF GEODYNAMIC PROCESSES IN THE DEVELOPMENT OF HYDROCARBON DEPOSITS
Authors V. Zhiriy, N. Goptarova, G. Zhuchenko, G. Gorvanko and V. ManiukSummaryHuman activity often leads to environmental degradation, the atmosphere, climate change, and changes in the Earth’s interior are felt by the activation of seismic phenomena, including earthquakes, even in areas that have traditionally been considered aseismic. In this regard, the role of geodynamic exploration of territories is increasing, especially for areas that are most exposed to man-made influence (underground mining, construction of large engineering structures - hydroelectric power stations, nuclear power plants, reservoirs, etc.). It is especially important to know the degree of geodynamic danger for oil production areas that have been exposed to anthropogenic impacts on their surface and subsoil over time (over 30 years). The factors that influence changes in the geological environment are analyzed and geodynamic monitoring is proposed.

ALGORITHM DEVELOPMENT FOR QUANTITATIVE ASSESSMENT OF RISKS OF GAS TRANSPORTATION PROCESS BY MAIN GAS PIPELINES
Authors V.M. Maniuk, O.R. Maniuk, M.I. Maniuk and M.I. MedvidSummaryThe problem of ensuring technological reliability and environmental friendliness of the natural gas transportation process, basic approaches to risk assessment and management at industrial sites are considered. To improve safety of gas transportation system facilities, a comprehensive risk management system is proposed, as well as a quantitative risk assessment algorithm. The main advantage of the proposed algorithm for the analysis of quantitative risk assessment over the traditional one is that the analysis reveals “vulnerability” in the technological processes; it is further used as a controlled and regulated parameter. While traditional risk assessment techniques focus on determining the risk event, and make it possible to draw conclusions only about the facility risk.

Authors S.E. Shnyukov, O.V. Andreev, I.I. Lazareva, E.T. Tegkaev and A.G. AleksieienkoSummaryThe existing global U-Pb age databases for zircons and monazites from rocks and large detrital populations were jointly analysed with the large original geochemical dataset. This dataset (whole-rock geochemistry, as well as single-grain trace element composition and total Pb age-dating of both minerals) obtained for Precambrian Ukrainian Shield (USh) rock associations, modern sediments and Phanerozoic sedimentary rocks from basins of USh periphery (accumulation reservoirs of eroded upper crustal material) yielded following results: (1) Distribution of SiO2, Zr and LREE in modern sediments and Phanerozoic sedimentary rocks is caused by two factors - sedimentary differentiation and sedimentary homogenization. Second factor erects a set of local contrast maximums in distributions, which reflect composition of upper continental crust. (2) It is vital to develop specialized criteria for zircon and monazite sampling, which can be based on a principle maximum conformity of SiO2, Zr and LREE concentrations in the drainage samples to evaluated concentrations in upper continental crust. (3) Interpretation of zircon and monazite data should take into account the mass of their grains and the concentration of both minerals in the source rocks. Application of this approach would significantly enhance reliability of further continental crust evolution study.

NUMERICAL MODELLING OF SALT TECTONICS WITH DUCTILE-BRITTLE DEFORMATIONS OF SALT OVERBURDEN
Authors D.B. Vengrovitch and S.M. StovbaSummaryWe present the results of numerical modelling of the dynamics of active salt diapir formation beginning with the initiation of salt movements due to thick-skinned extension of subsalt medium through later stages of creep and brittle deformations of the salt overburden up to the time of the emergence of salt at the surface of its overburden. The numerical modelling algorithm is based on a combination of full dynamic modelling (FDM) of any natural medium with simultaneous ductile and brittle behaviours and the finite element modelling (FEM) of viscous salt flow. The possible mechanism of the formation of highly tilted blocks nearby the walls of salt diapirs is explained by the FDM. The modelling results on the importance of buoyancy forces and erosion as driving mechanisms of the growth of salt diapirs conform to previous models obtained with the use of FEM. The results are also supported by observations in the Dniepr-Donets Basin. The modelling based on the FDM provides an effective additional tool for hydrocarbon exploration and making decisions on development of storage potential for radioactive waste and carbon dioxide.

Authors S.G. Anikeyev, S.E. Rozlovska, B.B. Hablovskyi, M.V. Shtogryn and M.O. KarpenkoSummaryGeological and economic efficiency of regional research of tectonics of oil-and-gas bearing regions of Ukraine, and also researches of geological structures of sedimentary cover, depends on taking into account of all geologic-geophysical information, including quality interpretation of high-precision gravimetric data. As practice shows, morphology of Bouguer gravity anomalies in scale 1:50000 and larger is high-informative for detecting and tracing tectonic zones, faults, and individual structural forms. The transformations of gravity fields allow identifying and tracing local anomalies among other anomalies. Preliminary analysis of frequency and relative depth characteristics of anomalies and also the parameters of the transformations determine the physic-geological content of the localized groups of anomalies. The variants of isotropic and anisotropic combined transformations of averaging, which, in accordance with their frequency and depth characteristics, are intended to detect in the gravity field of isometric or elongated local anomalies of a certain direction and the approximate depth of their sources are presented in the paper. The practical results of the application of these combined transformations are also given.

MULTIPLE REGRESSIONS AND ANN TECHNIQUES TO PREDICT PERMEABILITY FROM PORE STRUCTURE FOR TERRIGENOUS RESERVOIRS, WEST-SHEBELYNSKA AREA
Authors V. Antoniuk, I. Bezrodna and O. PetrokushynSummaryIn the processes of exploration, allocation of producing intervals, and development of hydrocarbon deposits, the important part is the accurate determination of the poro-perm properties. According to the complex of laboratory studies of the reservoir rocks from the West-Shebelynska area (depth interval 4929–5380 m), the authors predicted the permeability coefficient using the quantitative distribution of different types of voids in (the reservoirs of different types (intergranular, secondary, and fractured). With the help of Multiple Linear Regression (MLR), it was established that the filtration of fluid in the investigated complex reservoir rock samples occurs both in intergranular and secondary voids as well as in fractures. It is shown that Artificial Neural Network (ANN) and Multiple Nonlinear Regression (MNLR) algorithms can provide a stable model with a high degree of confidence that can be used to predict the permeability coefficient at the intervals studied.

MODERN SEISMICITY OF PODILLYA
Authors M. Baryshnikova and I. TsiupaSummaryUkraine is located near by the Vrancea seismic zone, which adjoins the southwestern borders of the country. This factor is one of the most important in seismic zoning. But earthquakes occur within the country as well.
In this work the modern seismicity of the territory of Podillya - an active platform region is considered.
Based on tectonic earthquake data for the period from 2004 to 2019, two seismically active zones were allocated on the territory of Podillya-Ternopil and Novodnistrovsk region. Both are confined to the zones of modern neotectonic activation. The activation of the Novodnistrovsk zone is associated with the functioning of the Dniester reservoir. Possible influence of weak local earthquakes, the focal areas of which are still poorly understood, should be taken into account while designing and building important and environmentally hazardous objects including hydropower constructions.

COMPARATIVE ANALYSIS OF ACOUSTIC ANISOTROPY IN ROCKS FROM PISHCHANKA IRON-ORE STRUCTURE
Authors I. Bezrodna, D. Bezrodnyi and V. SvystovSummaryAuthors have shown analysis of results of acoustic properties investigation of Pishchanka iron-ore structure (depth interval 144–273 m). Based on measured velocities of quasi-longitudinal and two quasi-transverse waves anisotropy parameters were calculated. Anisotropy coefficients analysis was performed using different methodologies: compressional, shear and acoustic. Vast majority of samples have high and average level of acoustic anisotropy of an ellipsoid. Based on acoustic tensor parameters most samples have rhombic symmetry type, minority - transverse-isotropic, what describes complex origin of the rocks on different depths. Dissidences in anisotropy parameters of given samples can be explained by essential difference in samples’ structures and discrepancy of size and form of the minerals’ grains.

EVALUATION OF CS-137 CONCENTRATION IN ONE OF THE LOCATION OF FINAL DEPOSITION ACCORDING TO GEOPHYSICAL EXPLORATION
By M. DanylovaSummaryResults of the radioactive contamination measurements by Cesium-137 of a repository are evaluated. Contamination are carry out with hole radiometry near the repository. Vertical curves of exposure dose rate have a mutual feature — an absence of high values at low depths that corresponds to bulk layer of soils and sharp increasing of exposure dose rate in 60–80 cm that reflects an upper level of repository. Complex software MicroShield was used during data processing of gamma-ray log and specific activity of Cesium-137 determination in radioactive waste gatherings. Software functions with a wide range of geometry options give an opportunity to represent the exact conditions in the well. This allows us to increase the resolution of calculations, minimizing the possibility of possible uncertainties and determine radioactive characteristics inside the buried radioactive waste. Furthermore, determination of buried radioactive materials characteristic afford making rational administrative and projective decisions on how to safely eliminate and behave with radioactive waste.

MAGNETOMINERALOGICAL SUBSTANTIATION OF MAGNETIZATION OF THE ROCKS OF THE LOWER CRUST AND UPPER MANTLE
Authors V. Drukarenko, M. Orlyuk and O. ShestopalovaSummaryRecent researches have been shown that sources of longwavelength geomagnetic anomalies are located at upper mantle depths to which earthquake sources may be associated. Therefore, there is a requirement of magnetomineralogical and physical justification for the possibility of the existence of magnetized rocks at these depths. The main minerals retaining magnetic properties in the lower crust and upper mantle are magnetite, haematite, native α -Fe iron and its alloys. The emergence and transformation of iron minerals and reducing of α -Fe can occur due to the reactions of reducing fluids with different iron compounds and rocks in particular at junction zones of lithospheric plates of different types, rifts, plumes, tectonic-thermal activation, etc. The mantle xenoliths are the main sources of information of mantle magnetization and characterized by pure magnetite inclusions in olivine and pyroxenes. Magnetite is formed due to serpentinization processes in the mantle peridotites. Iron oxides and native iron are potential sources of magnetic anomalies in the mantle. Studies have shown that haematite remains magnetic at depths of transition zone in the mantle in cold or very cold subduction geotherms. α -Fe can be found in the lower crust and upper mantle due to the low oxygen fugacity and the reducing nature of the geochemical environment.

RADIOECOLOGICAL MONITORING OF LOCAL SOURCES OF EXISTING AND POTENTIAL RADIOACTIVE CONTAMINATION USING GEOINFORMATIONAL SYSTIM
Authors O. Fedchenko, I. Syniavska, N. Levinskova, P. Savkov and V. SavkovaSummaryRadioecological monitoring is a complex information and technical system for observation, research, evaluation and forecasting of the radiation status of the biosphere, areas near NPPs (Nuclear Power Plants) affected by radiation accidents, and potentially hazardous areas (PNT) such as radioactive waste storage facilities, radioactive waste storage facilities (threat of nuclear weapons), nuclear power plants (NPPs), nuclear fuel manufacturing and processing enterprises, nuclear reactors, nuclear power plants at transport facilities. The territory of Ukraine needs a perfect system of radio-ecological monitoring several times more than any European country. Unstable military-political situation, numerous explosions of ammunition arsenals lack of RW repositories that meet international standards. By volume of radioactive waste, Ukraine is ranked II in Europe and IV in the world (3.5 million m3). This is the main reason for the need to constantly control and monitor the state of sources of existing and potential pollution of the territories.

PETROPHYSICAL MODEL FOR POROSITY DETERMINATION OF COLLECTORS WITH DIFFERENT CONTENT OF CLAY MATERIALS ACCORDING TO THE ACOUSTICAL AND RADIOACTIVE RESEARCHES
Authors D.D. Fedoryshyn, V.V. Fedoriv and R.O. MarynchakSummaryAccording to the results of studies of the geological structure of productive rocks-collectors of perspective horizons of gas deposits of the Precarpathian Strait and the Dnieper-Donetsk basin, it is established that gas-saturated layers are represented by monomictic sandstones and siltstone with different types of cement. The analysis of information from the literature and methodological recommendations for the determination of porosity showed that the clay greatly affects the results of geophysical studies of wells, in particular acoustic and neutron logs. In this work the possibility of taking clay into account when determining the porosity coefficient using the results of gamma logging studies is considered. As a result of the simulation, a new unified petrophysical model for determining the porosity of reservoir rocks with different content of clay material was obtained, according to the well studies of acoustic and gamma logs.

CORRELATION AND CLUSTER ANALYSIS OF PRINCIPAL GEOLOGICAL PARAMETERS OF GIANT HYDROCARBON FIELDS
Authors G.N. Gahramanov, N.R. Narimanov, M.S. Babayev, S. Shpyrko and M.T. BabayevaSummaryWe consider the problem of extraction of relevant geological parameters, related to the formation conditions of major hydrocarbon (HC) fields and estimation of their resource potential. The identification of most informative sets of geological parameters and revealing correlation dependencies between them is of crucial importance for HC exploration. Experience has proven, that 10–15 geological parameters have high information impact and can be used to estimate HC potential in most sedimentary basins. These parameters characterize sedimentation conditions, tectonic environment, organic matter transformation, location of the oil and gas accumulation areas etc. Depending on the geological conditions, relations of various nature can exist between these parameters, which can be characterized by pairwise correlation coefficients. We present the pilot study of the pairwise correlation coefficients between the metric subset of these parameters, calculated from data set of major world basins, including Azerbaijan giant fields. Several alternative graphic models are proposed (including trend curves, correlograms, chord diagrams and clustered dendrograms) to visualize the dependencies and to derive conclusions as to the impact of these parameters on the probability assessment of the HC field formation.

LOCATION OF GAS-SATURATED OBJECTS OF UNCONVENTIONAL TYPES IN THE WELL SECTIONS BY THE WELL-LOGGING DATA
Authors O. Karpenko, V. Mykhailov and I. BaysarovychSummaryOn the basis of authors own experience, it was made an attempt to analyze the possibilities and modern approaches of identifying unconventional reservoirs and to give practical recommendations for assessing their prospects. The issues of practical implementation of interpretative models for determination of TOC content, clay content and porosity in the well sections with the purpose of estimation of shale gas resources are considered. The main criteria and limitations for the allocation of perspective objects in well sections are presented in order to realistically account for shale gas resources and gas of tight reservoir rocks. It is shown that the use of the most commonly used method of Q. Passey is quite effective in calculating the TOC content in terrigenous sections of the Serpukhovian of oil and gas fields of DDD. Typical values of gas saturation coefficients and range of possible porosity values inherent in tight reservoir rocks of the Serpukhovian of the of the South side of the DDC are presented and recommended by the authors.

Authors I. Kurovets, A. Shyra, Y. Shpot, S. Kurovets and V. KurovetsSummaryNetwork models of porous media are a useful tool for predicting transport properties of hydrocarbon reservoir rocks. This work explores the possibility of using a reconstructed three-dimensional pore space model, obtained by means of multi-point statistical modeling based on thin images of reservoir rocks, to construct a bi-regular network model based on truncated octahedral nodes. With this model, it is possible to simulate pore systems with a wider range of pore connectivity, making the proposed model more realistic and flexible than existing cubic-based models. It is shown that using these models it is possible to accurately predict the experimentally measured permeability of the sample.

THE CHEMICAL COMPOSITION OF THE THORIUM ORTOSILICATES FROM ALBITITES OF THE NOVOOLEKSIIVKA THORIUM-URANIUM OCCURRENCE (UKRAINIAN SHIELD)
Authors I. Mihalchenko, O. Andreev and S. ShnyukovSummaryThe chemical compositions of pneumolithic-hydrothermal Thorium orthosilicates from the albitites of Novooleksiivka occurrence are characterized by admixture of Uranium, Rare Earths elements, Yttrium, and some Phosphorus. Thorites and Uranothorites have been identified in albitites. Ferritorites are epigenetic minerals. The chemical compositions of Thorium orthosilicates from the albitites are characterized by admixture of Uranium, Rare Earths elements, Yttrium, and some Phosphorus, which gives the basis for these minerals due to the decomposition of magmatic Monazites of the original rocks. The spectra of Rare Earth elements of Thorium orthosilicates are not constant, which is a sign of the fractionation of these elements in the processes of pneumolithic-hydrothermal alteration of the original rocks. The signs of the Uranium and Thorium leaching, migration and deposition testify of the existence of conditions of transportation of Uranium in the U4+ uranium oxidation state in the fluid, that generated rocks.

REPEATED GEOPHYSICAL RESEARCHES OF HAZARDOUS GEOECOLOGICAL PROCESSES NEAR MINING WASTE STORAGE FACILITIES OF SOUTHERN KRYVBAS
Authors P. Pihulevskyi, V. Svystun, O. Tiapkin, A. Tolkunov and S. SlobodianiukSummaryModern mining processes in Kryvyi Rih iron ore basin (Kryvbas) are accompanied by hazardous geoecological events. The complex tectonic and hydrogeological interpretation of geological-geophysical data are necessary to prevent accidents at mining hydraulic facilities (and first of all - tailing ponds) and successfully design their increase. On an example of detailed geophysical research near the storage pond of highly mineralized mine waters in Svistunovo gorge (Southern Kryvbas) is shown that intensive tectonic fragmentation of rocks is the reason for increasing filtration parameters and deterioration of physical and mechanical properties of rocks and as a result - dangerous intensification of exogenous geological processes and contamination of underground water. It is proposed to create a regional seismic monitoring system (as one of the main subsystem of environmental monitoring of Dnipropetrovsk region) with a control center in Dnipro-city and 3 local subsystems in the main mining areas in the region: not only Kryvbas, but Nikopol manganese basin and Western Donbas coal basin.

MODERN DEFORMATION AND NEWEST MOVEMENTS OF THE EARTH’S SURFACE ON THE TERRITORY OF UKRALNE
Authors M. Orlyuk and M. IshchenkoSummaryThe article discusses the current deformation of the Earth’s surface based on the analysis of the Global Navigation Satellite Systems (GNSS) data from the GAO NAS of Ukraine in comparison with the latest lineament zones and faults, as well as with the late Pliocene-Quaternary vertical movements of the Earth’s crust. According to the results of the analysis of high-precision coordinates and displacement vectors of permanent GNSS stations in the territory of Ukraine, deformation parameters of the Earth’s surface were obtained, areas of prevailing compression values — tension and left-right-side rotation of the Earth’s surface were identified, the boundaries between which can be drawn along the latest lineament zones and faults. The areas of the predominant stretching of the Earth’s surface corresponding to the zones of the newest tectonic uplifts (Volyn-Podolsk and Periazov hills) and maximum amplitudes of the Pliocene-Quaternary movements and the areas of prevailing compression are zones of tectonic descents, minimal amplitudes of Pliocene-Quarternary movements. Four large modern geoblocks have been identified: North-West and North-East, which rotate clockwise, and South-West and South-East rotating counterclockwise. At a qualitative level, a mechanism is proposed for the interrelationship between modern and newest movements of the Earth’s crust.

SEISMIC OBSERVATIONS IN THE LOCATION OF THE STEBNYK POTASSIUM SALT DEPOSIT
Authors I. Sapuzhak and S. VerbitskyjSummaryThe history of the production of potassium salts near Stebnik is briefly mentioned, as well as the accident at the Polimineral enterprise due to hydrogeological phenomena. Given the global experience in dealing with such situations, it is proposed to use seismic observations to locate hazardous processes in a salt mine under the developed project of the system for monitoring the location of the deposit. Observation began in October 2017 with the installation of one temporary point of seismic observations - seismic station ““Stebnik”“. It is given the description of the hardware and software complex of the seismic station, the main technical characteristics, the results of observations and their processing - catalogs of registered seismic events, examples of registered waveforms of regional and telesemic events, as well as local earthquakes in the Stebnik district, the map of their localization. To process instrument records of this seismic station, data recorded at seismic stations of the Carpathian Regional Seismological Network “Skhidnytsya” and “Morshyn” were used. On the eve, some organizational issues were resolved and at the end of August 2019 2 more temporary seismic observation points were installed - the Kozatsky hutir and Zolota gora seismic stations (named after the recreation complexes). Test procedures are currently underway and the seismic monitoring system, consisting of the mentioned stations and Stebnik, Morshin and Skhidnytsia stations, will be operational soon.

NONLINEAR WAVES PROPAGATION IN EARTH’S CRUST AS PRESTRESSED CHAINS OF BLOCKS
More LessSummaryWe propose a new concept in the approach to the seismic process study. And the new seismic theory will improve potentialities of monitoring and modelling of natural hazards and new technologies for risk minimization and prevention. This work is a continuation of the seismic waves propagation study caused by irregularity of lithospheric stress as a result of plates structure. The given research as the numerical modelling of the chain of grains dynamics was performed to study the possibility of nonlinear soliton waves propagation in lithosphere. We take the Earth’s crust for a structured block media consisting of separate blocks and when modelling these are shaped like cubes with close sizes. It is important for understanding of Earth’s plates tectonic mechanisms, stress growth and localization, seismic manifestations of the stresses release in the form of earthquakes. From the point of view of such a model we studied the tectonic process such as subduction. We have shown that a feature of the evolution of the stress-strain state of block models is the formation of chains of stressed blocks that permeate the model. Studies have shown the finite-element model of nonlinear wave propagation in chains blocks of an arbitrary form interacting at contact.

HYDRAULIC FRACTURE CRACK PROPAGATION MODELING IN MULTI-COMPONENT NONELASTIC GEOLOGICAL MEDIA
Authors S. Vyzhva, B. Maslov, I. Onyshchuk and O. KozionovaSummaryTight gas is very important unconventional hydrocarbon resource that is beginning to be a priory kind of energy in Ukraine. It stored in multi-component geological media, whose mechanical behavior may be considered as elastic one only, as a first step of approximation, or visco-elastic in common case. We investigate this problem by adopting the quasi-linear fractional Rabotnov model. These fractures serve as pathways for gas flow, and the maintenance of such fractures is of practical significance to the long-term recovery of tight gas. The main question to what extent will the fractures close due to the viscous deformation of tight sandstone, in a relatively long period of time. The second, during the visco-elastic creep, possible tensile stress in hydro fracture zone, can reduce the long-term strength of multi-component media. Previous results of authors were used. On the base of the quasi-linear theory of visco-elasticity, the constitutive equation for isotropic media in the presence of initial stress is derived. The equations governing infinitesimal motions superimposed on a finite deformation are used to study the effects of initial hydro-fracture stress on the creep parameters in multi-component geological media. Computer modeling was realized to evaluate the risk and reliability parameters in exploitation period.

THE MAPPING OF SUBMERGED (FLOODING) LANDS BY GEOPHYSICAL METHODS
Authors S. Vyzhva, V. Onyshchuk, I. Onyshchuk, N. Reva and O. ShabaturaSummaryThe paper discusses the results of the basic principles of flooding processes by geophysical methods. To apply geophysics for new tasks, it is necessary to obtain and study various information about the upper part of the section (UPS) and discriminate its all layers. Each horizon has to be traced in plane and depth, and its geophysical parameters have to be determined as accurate as possible. Then use these data as the basis of geophysical mapping of soils the horizon-oriented geophysical maps, geoelectric sections and other graphic materials, which are formed. The result of processing and interpretation of geophysical survey data is a set of geological and geophysical sections and horizontal maps of electrical resistivity of soils and rocks of UPS. In this paper as an example, we share some results of the geophysical mapping technique for soil condition at the Chornobaivska key site, located on the eastern part of the Dnieper-Donetsk Basin.

GEOSPATIAL MODELLING AND RESERVES ESTIMATION OF WADI AL SHATI IRON ORE DEPOSIT (LIBYA)
More LessSummaryMineral exploration procedures always need to integrate data in order to consider a vast range of combinations and to underline different hypotheses. Reserves estimation, either globally or regionally, has become a typical geostatistical application within the mining industry. Kriging could be a geostatistical interpolation technique utilized in the mining industry for interpolation of input purpose information and estimation of a block model (mineral resource model). In order to estimate Wadi Al Shati iron ore deposit, input data gained from 109 boreholes were used. Fe grade was selected as the major regional variable on which the present research has focused. Studies indicated that iron grade input data had single population characteristics of the area which is totally covered with sand dunes to discover any probable occurrence of iron ore. The results showed that the iron ore belt still extends the west and southwest part under the sand dunes. Finally, a new potential map for the areas of iron ore deposit was produced.

MONITORING AND ASSESSMENT OF IMPACT OF MUNICIPAL SOLID WASTE LANDFILLS ON THE SURFACE WATER QUALITY IN THE ADJACENT PONDS
Authors O.T. Azimov, Ye.M. Dorofey, O.M. Trofymchuk, I.V. Kuraeva, K.S. Zlobina and S.P. KarmazynenkoSummaryThe monitoring ecological hydro-geochemical investigations for the surface waters of the north-western part of Landfill No 5 for the municipal solid waste disposal and the adjacent area are carried out. Based on analyses of surface water samples taking from the existing ponds, it was found that they are polluted by wastewater with the high content of organic toxicants predominantly. Most likely the latter comes from both the Sections and ponds-collectors of leachate or from the pig farm, which is located near the Landfill but hypsometrically higher in relief. In order to specify the answer the more studies are required. Contrary, surface waters beyond the Landfill area are characterized by the ecological and hydrogeochemical indicators, which no higher than the maximum allowable concentrations, although they are higher than the background ones. This indicates that the considerable outflow of chemical pollutants together with the surface waters from the north-western Landfill No 5 area beyond of its borders during for more a year is absent. Only the short-time periodic monitoring of the water bodies within the territory of interest able to determine such time intervals when water could be polluted by various toxicants.

LONG-TERM DYNAMICS AND CURRENT TRENDS IN FLUCTUATIONS OF THE FLOW CHARACTERISTICS OF THE SIVERSKYI DONETS RIVER BASIN
More LessSummaryLong-term fluctuations of average annual flow, maximum flow of spring flood, warm and cold period’s floods, the minimum flow of the winter and the summer-autumn low periods of the Siverskyi Donets River Basin are analysed. A decrease in the minimum characteristics of winter flow (winter low period) and maximum flow characteristics of the cold flood were found. The lows and highs of flow of the cold period do not significantly differ from the lows and highs of the warm period at the present period (2008–2017). Three groups of rivers are identified for belonging to a particular part of the Basin. Differences in trends of flow fluctuations for the Left-bank, Right-bank tributaries and the Siverskyi Donets River are analyzed. Some differences in the fluctuations of the flow of the Left-bank tributaries and, in particular, of the Siverskyi Donets River and, separately, of the Right-bank, were revealed. It is established that there is a dry phase from 2008 till nowadays on the rivers of the Siverskyi Donets River Basin.

MULTIPURPOSE CLASSIFICATION OF THE SUBSYSTEMS OF GEOLOGICAL-ECOLOGICAL SYSTEM OF THE BLACK SEA BOTTOM DEPOSITS
More LessSummaryAnalysis of the properties of the internal geological and ecological conditions of different spatial components of the geological-ecological system of bottom sediments of the Black Sea, as well as the processes of their interaction with external natural and anthropogenic-natural systems and other objects allowed the author to distinguish in the Black Sea a number of subsystems, to classify them according to specific characteristics and to assign them to different taxa (classes, groups, types, species, etc.) of the multipurpose classification of the subsystems of geological-ecological system of the Black Sea bottom deposits. The Classification was developed by the author using the theoretical and methodological fundamentals of marine geoecology and based on geo-ecosystem analysis of a considerable amount of geological, engineering-geological, oceanographic and ecological data, including data on the substance-genetic composition of bottom deposits, characteristics of structural links between their geo- and bio-constituents, etc. The presented Classification can be used as a basis for solving a number of fundamental and applied problems of marine geoecology, in particular at the stage of development of projects of construction of underwater hydraulic structures and communications, resource development, geo-ecological zoning, planning and implementation of monitoring, etc.

MODELING IN MONITORING SYSTEM OF UNDERGROUND HYDROSPHERE FOR TERRITORIES UNDER TECHNOGENIC PRESSURE
Authors O. Koshliakov, O. Dyniak and I. KoshliakovaSummaryThe authors provide evidence of the necessity to take into account underground hydrosphere state in assessing the stability and dynamism of urban natural-technogenic geosystems. This is because groundwater disturbance often leads to the emergence or activation of negative engineering-geological processes and even hazards. Detailed hydrogeological study of the territories in order to assess the existing natural-technogenic situation requires a change in classical approach to underground hydrosphere monitoring. It is proved that the use of statistical modeling based on spatial analysis and modeling in GIS allows the most efficient use of a small input data amount and to make prediction with the help of deterministic mathematical modelling.

MONITORING OF THE STATE OF THE GEOLOGICAL ENVIRONMENT AND ANALYSIS OF THE OF SUBMARINE VOLCANISM IMPACT ON THE GEOECOLOGICAL CONDITIONS OF THE BLACK SEA DEEP SEA ZONE
Authors V. Iemelianov and O. IvanikSummaryThe Black Sea is a unique geo-ecosystem with special hydrological, geochemical, geological and biotic subsystems. The environmental ecological subsystems of the Black Sea geo-ecosystems, namely marine aerial, aquatic and marine geological ecosystems, have certain natural features of internal ecological conditions. Wide development of gas- and mud volcanic processes in the deep sea zone of the Black Sea and the dissemination of gas emissions mainly of methane composition have a huge impact on the material composition of the components, the physical-mechanical and engineering-geological conditions. This necessitates monitoring studies of the state of the geological environment of the Black Sea because of the need to identify and understand the features of the temporal and spatial dynamics of its degassing processes. A comprehensive study of gas volcanism, gas discharge and gas hydration phenomena of the deep sea zone of the Black Sea, showed that submarine mud volcanoes and methane eruptions are not only a reliable indicator of prospects for the detection of offshore hydrocarbon fields, but also is a very important factor of the geosystem existence. In the development of special technologies, reactive gas emissions can become a promising source of hydrocarbons as an energy resource.

THE METHODICAL APPROACH TO THE DETERMINATION OF GEOLOGICAL RESERVES CHEMICAL COMPONENTS IN THE PRODUCED WATER OF OIL AND GAS FIELDS
More LessSummaryThe produced water (PW) of oil and gas fields is a cost component of their development. The article determines that these waters contain a large number of dissolved chemical components. Components contained in PW have an industrial value. The authors point out that oil and gas companies can extract these waters from the cost component into the revenue component when extracting useful components from the PW. The authors state that geological and economic assessment is needed to use PW as a raw material. This paper proposes a methodological approach to the geological and economic assessment of chemical constituents in PW. The methodology is based on several basic criteria. The work identifies the volumes of extraction of PW, concentrations of chemical components, industrial concentrations, the term of development of the deposit are the main criteria for geological and economic assessment. The paper gives an example of determining the geological reserves of useful components at the Lelyakivskoye deposit. The authors classify these stocks according to the current regulatory documents. The result is that this technique allows these stocks to be converted from code 3.3.3 to code 1.1.2. The authors conclude that the code change should attract investors to the development of PW as a valuable resource.

VARIOGRAM ANALYSIS TO MEASURE THE SPATIAL STRUCTURE OF BRIOGEOCHEMICAL FIELD OF NORTHERN UKRAINE
Authors Yu. Tyutyunnik and O. ShabaturaSummary“Variogram analysis allows revealing the spatial structure of the biogeochemical data, to group elements according to their similarity of their biogeochemical behavior, and describe the mechanisms of their concentration in mosses. The concentration macroelements in moss make up a composite geochemical field that is determined by a combination of several factors: availability of mineral and chemical forms of elements for their assimilation, the presence and magnitude of the physic-biological barriers in the environment.
The most concentrated are the biophilic elements (S, P, K, Ca, Mg,) and B, which are capable of vigorous and strong biological adsorption. Excluding of K, their spatial size are beyond the limits of geostatistical study, meaning that they have an immeasurable scale. This is probably a reflection of the effect of the mineral substrate.
Such macroelements as Fe, Al, Na and K have a clear rank, which indicates the different size of the spatial factors and, probably, caused by a hydromorphic complex. The association of trace elements in moss have similar variogram with one rank, may be a reflection the territorial differences of the aerial fall-out of heavy metals.”

OIL AND GAS PERSPECTIVES OF ATESHGAH STRUCTURE (BAKU ARCHIPELAGO) IN THE CONTEXT OF ITS GEOLOGICAL HISTORY
Authors V.Sh. Gurbanov, M.S. Babayev, N.R. Narimanov and S. ShpyrkoSummaryThere is a direct relationship between the deposition rate in a basin and the amount of accumulated organic matter. We try to establish the potential of relevant lithologic units as mother rocks, determining the depositional rates for different geological time spans based on the lithological and stratigraphic cross-section of the area. As case study, Ateshgah uplift is considered as a large offshore anticline structure in the central part of Baku archipelago in the Caspian Sea. From the reconstructed paleoprofiles (backstripping technique), the rates of the fold development depending on the geological epochs can be approximately assessed. Fold growth rates for this structure steadily increased throughout the time eventually reaching the values of 0.5–1.3 km/mln yr. This result is in agreement with similar paleographic reconstructions, recently reported for other prospective structures in the region. With the exception of Paleocene and Eocene, the remaining stratigraphic intervals were favorable for the accumulation of organic matter in potential mother rock at least exceeding the Clarke number.

DEVELOPMENT OF ALGORITHM FOR CALCULATING EXPOSITION VALUE OF CO2 CONCENTRATION IN AIR FOR TASKS OF MONITORING OF SOILS OF UKRAINE POLISSYA AGRO-LANDSCAPES
Authors O.I. Bondar, P.I. Trofymenko, N.V. Trofimenko, V.I. Zatserkovnyi and F.I. BorysovSummaryThe paper presents the results of field analytical studies and development of an algorithm for calculating the exposure value of CO2 concentration in the air of Ukraine Polissya agro-landscapes soils. A clear procedure for calculating exposure time for in situ studies is given, depending on the intensity of soil air exchange. Depending on the 6 types of air exchange intensity, approximate measurement time ranges are established to measure soils with too difficult, relatively difficult, satisfactory, good, very good and excellent intensity level of air exchange. It is defined that the time range of measurements of the value of CO2 concentration in the ground air, the soil organic matter reserves, as well as the determination of diffusion coefficients in situ conditions are in the range of 2 to 11 and more hours. In case of unsatisfactory values of soil diffusion coefficient (due to unfavorable granulometric composition, over-wetting, excessive compaction), the measurement time for carbon dioxide concentration in the ground air exceeds 5 hours. In the case of favorable values of D, the measurement time usually does not exceed 2–3 hours, characterizing this method of measurements as an express method.

MORPHOSTRUCTURAL POSITION OF “MEZHYRITSKYI CAPE”: GEOARCHAEOLOGICAL ASPECT
Authors S. Bortnyk, O. Kovtoniuk and N. PohorilchukSummaryThe article deals with the unique morphostructural position of “Mezhyritskyi Cape”, which in late Paleolithic was the location of the mammoth hunters’ site. The Cape forms the site of merger of the Ros and Rosava rivers between two neotectonically active regions of the dislocation of the Mesozoic-Cenozoic sedimentary cover, which are expressed in the relief of the Kaniv Mountains and Moshnohirsk ridge. This is a complex morphostructural unit — a place of intersection of multi-order linear morphostructures and interference of morphostructures of the central type. It was formed as a result of a long and complex transformation of active tectonic factors that controlled the course of exogenous relief-forming processes on the earth’s surface. The latter, together with the climatic characteristics of the territory, controlled the landscape structure of the land, which primitive people used for their needs. The triangular shape of the cape and the rivers on both sides made it a convenient and optimal location both in terms of farming and security. The geodynamic activity of this small terrain, which was expressed in the formation of the morphostructural unit here, led to the localization of activities of the ancient man exactly in this place.

AN ANALYTICAL ASSESSMENT OF MECHANICAL STABILITY CONDITIONS FOR NATURAL SOILS USING CORE DATA FROM GUSAR-DIVICHI TECTONIC ZONE
Authors H. Guliyev and A. HasanovSummaryArticle describes detailed analytical review of influences different types of deformation processes, from elastic deformation to plastic fracture, which could cause secondary changes of primary inter granular porosity and fluids permeability of soils.
Was revealed that the mechanical stability of soils can be determined by calculating the gravitational forces existing in a specific volume of sediment, relative to the friction forces. In this case size of the rock-forming grains, values of inter granular friction, and the pore water content acquire decisive importance. The latter circumstance, respectively, is characterized by the natural porosity of the rocks, the packing density of the grains, and pore pressure.
It was revealed also, that the fine-grained soils sediments, such as clay, have a significant amount of inter granular friction and this often prevents clay deposits from sliding, even with low inter granular friction. However, if in clay the pore pressure approaches the weight of the overlying deposits, then the friction component of the slip approaches zero. Therefore, clay, silt and fine-grained sand are the most liquefied fractions and can generate “liquefied streams”.

MAPPING OF THE SOIL MAGNETIC SUSCEPTIBILITY FOR THE EROSION PROCESSES MODELING
Authors O. Kruglov and O. MenshovSummaryThe crucial aim of the present study is to investigate the possibility of using soil magnetic susceptibility (MS) for the correction of the results of erosion modelling. The studies were performed on the example of the typical chernozems of Forest-Steppe of Ukraine. We used the magnetic techniques, agrochemical, statistical, and mathematical modelling of the erosion processes. The example of the chernozem soil studies illustrated the possibility of using soil magnetic susceptibility data for the improving and correction of the results of mathematical modelling of the erosion processes. According to the obtained data we recommended to include the magnetic susceptibility measurement to the algorithm of the calculation of the soil coefficients. The soil erosion models are related to the distribution of MS values.

PLISNESK ARCHEOLOGICAL COMPLEX. SOME RESULTS OF MAGNETOMETRY PROSPECTION
Authors R. Kuderavets, I. Chobotok, O. Menshov, V. Shelep and A. FylypchukSummaryThe results of the magnetic studying over two archaeological excavations at the territory of the “Ancient Plisnesk” historical and cultural reserve are presented. According to the magnetic data, the anomalous of the magnetic field were detected. The studying of soils, sediments, and archaeological materials were performed at the western wall of the excavation. The most magnetic horizon in the section of the excavation wall is at the interval of 40–65 cm, where black loams, burnt clay layers with orange colour were identified. Mineralogical composition of the top soil is more complicated according to the influence of the pedogenic magnetic material. The deep clays include big amount of the paramagnetic material. We proposed the search criteria for some archaeological objects based on the magnetic field indications. The high efficiency of magnetometry to identify and delineate historical monuments from different periods before the start of archaeological excavations on the territory of the Plisnesk archaeological complex was proved.

WIND POWER STATIONS CONSTRUCTION IN THE MOUNTAIN ENVIRONMENT. PRELIMINARY RESULTS OF COMBINING SOIL MAGNETIC AND HYDROGEOLOGICAL METHODS FOR THE RISK ASSESSMENT IN UKRAINE
Authors O. Menshov, O. Shevchenko and R. KuderavetsSummaryWind power stations has been the subject of dramatically increasing interest in recent years. Wind power generation technology is now relatively mature, with annual generation amounting to 640 TWh, accounting for less than 3% of the world’s total energy consumption. Recently, we started the studies devoted to the environmental risk assessment of the wind power station constriction at the Borzhava in Carpathian Mountaions is Ukraine. The impact of wind power stations on the environment is not sufficiently studied yet. There is practically little experience in constructing and operating wind power stations at the high mountain valleys (1400–1700 m). The crucial aim of the present study is to consider the preliminary soil magnetic measurements and hydrological modelling based on the experience previously obtained at the Carpathian Mountain area in Ukraine.

RISKS OF DEPLETION OF PHYTODIVERSITY OF HYDROPOWER INSTALLATION INFLUENCE ZONES, INTRODUCTION OF THEIR INTEGRATED ECO-MONITORING AND DEVELOPMENT OF EFFECTIVE MEASURES TO MINIMIZE THE NEGATIVE IMPACT ON THE SURROUNDING PHYTOSYSTEMS
Authors V. Novosad, O. Scherbakova and K. NovosadSummaryOver the past decade the state has been focusing on renewable natural resources for electricity production, including hydropower. A number of large and small hydroelectric power plants are under construction or at the designing stage. Influence zones of their storage basins bear a number of risks to the surrounding natural landscapes and biodiversity. In particular, they are manifested in the flooding and inundation of natural vegetation communities, their halophytisation, the acceleration of abrasive and landslide processes of the bank line, the phytoinvasion intensification, as well as urban and recreational phenomena intensification. All of this leads to the risk of reduction in species and ectopic phytodiversity, particularly rare ones included into regional, national and international conservation programs. For each hydropower installation researchers develop a special program for scientific study of indigenous and adventive phytodiversity, ecotopological differentiation and synantropization, and implement a system for phytomonitoring of natural species, population and ectopic diversity. Based on the evidence found for the technogenic storage basin influence zones, they develop a system of effective measures for the conservation of rare phytodiversity, creation of a number of nature reserves and reduction of invasive species expansion. The purpose of the rare and invasive plant species population monitoring program is the following: the comprehensive population analysis of rare, vulnerable, endangered and expansive invasive species of vascular plants in the regional flora, and, on its basis, the development of effective conservation measures for rare species and an action plan to regulate the number and expansion of individual adventive plant species having a harmful effect on humans and causing biological pollution of natural phytosystems.

INFLUENCE OF REDOX CONDITIONS ON THE TRANSFORMATION OF MAGNETIC PROPERTIES OF MAGNETITE NANOPARTICLES
Authors V. Ponomar, T. Antonenko, M. Bahmut, O. Vyshnevskyi and O. BrikSummaryMagnetite is a common mineral in soils that can be both pedogenic and lithogenic in origin. However, magnetite is unstable in environment and can undergo various changes in structure and magnetic properties, which in turn affects the magnetic properties of soils. These changes are quite diverse and depend on temperature, time, redox conditions, etc. In this work, the transformation of magnetite nanoparticles by heating under oxidizing and reducing conditions was experimentally investigated by thermomagnetic analysis and magnetometry. The results showed that the mass magnetization is stable when heated to 500°C. However, there is a marked increase in Curie temperature from 580 to 650°C, which can be explained by the formation of maghemite. When heated above 500°C, the magnetization begins to decrease and reaches its minimum value at 900°C, which indicates the formation of weakly magnetic hematite. In addition, an unknown phase with a Curie temperature of 420°C appears at 500–900°C. Under reducing conditions, magnetite’s magnetization moderately increases, suggesting the partial reduction of Fe(III) to Fe(II), which results in improved stoichiometry. The results obtained provide new data on transformation pathways of magnetite/maghemite nanoparticles, which can occur in soils and crucially affect their magnetic properties.

RECONSTRUCTION OF SURVIVAL CURVES IN THE STUDY OF SOFT-BODY ORGANISMS’ NATURE AND LIVING CONDITIONS FROM UPPER VENDIAN DEPOSITS IN THE MIDDLE DNIESTER AREA
By A. MienasovaSummaryTirasiana Palij’s imprints were investigated by statistical methods. These imprints belong to radially symmetric organisms and are found in Vendian deposits of Middle Dnister area, Ural and White Sea. “Survival curves” was created from a sample of 29 specimens. It was proved that they are similar to curves of fairly highly organized species, which are characterized by care for progeny and the save of experience during the adult stages of ontogenesis. This seems unlikely, since we consider that they are the oldest non-skeletal sedentary Metazoa. The main factor controlling the organism final size was the periodic flow of a large amount of terrigenous deposits into the basin, which buried the benthic settlements in the sublittoral zone. A longer life time was provided to those specimens who found themselves in well-protected (for example, some brow or bay bar) parts of the water area. Giant sizes of “medusoids” (up to 1 m), known at some locations, can indirectly confirm this assumption. The predominance of small imprints suggests that reproduction occurred synchronously and was confined, like all species, to the most favorable and safe period (probably the dry season).

MONITORING OF THE MICROBIOLOGICAL CONDITION OF VIRGIN CHERNOZEM UNDER DIFFERENT MANAGEMENT
Authors O. Tonkha, O. Pikovska, A. Balaev, G. Kovalyshyna, V. Zavgorodniy and V. KovalenkoSummaryThe monitoring of soil conditions in the present conditions is becoming increasingly important because of the increasing of anthropogenic impact on the soil, including intensive agricultural use. We investigated the chernozems typical of the “Mikhailivska Tsilyna” reservation and the chernozems ordinary of the “Khomutovsky Steppe” reservation, as well as their plowed analogues, soils under forest strips, etc. For this purpose, methods of laboratory analyses of soil samples were used to determine microbiological parameters (according to D.G. Zvyagintsev). After the ratio between the number of microorganisms that use mineral forms of nitrogen to those decomposing organic forms of nitrogen the coefficient of mineralization - immobilization was calculated. According to the coefficient of immobilization-mineralization, it is established that agricultural use of chernozems leads to intensive transformation of organic matter. This is a prerequisite for reducing the intensity of use of chernozem soils reducing the depth of their cultivation.

ORGANIC CARBON CONTENT IN THE OLD-ARABLE SOILS OF THE UKRAINIAN POLISSIA FOREST ECOSYSTEMS
Authors S.P. Raspopina, V.V. Degtyarjov, P.I. Trofymenko, N.V. Trofimenko and V.I. ZatserkovnyiSummaryThe results of studies on the content of organic carbon in the block “phytodetrite - soil” of forest ecosystems in Zhytomyr and Chernihiv Polissia are presented in the paper. It is shown that under the conditions of water irrigation regime and predominance of coniferous vegetation the process of humus accumulation in old-arable sod-podzolic soils of automorphic type due to their sand granulometry (average particle content <0.01 mm - 6.8 %) is characterized by low intensity. The thickness of the profile humus portion is 18 ± 1.3 cm, the humus distribution is sharply falling with the depth - from 1.4% in He-horizon to 0.19 in Ph horizon. The carbon content in the automorphic soils is on average 0.74%, its stocks are 33.9 t / ha and in hydromorphic organogenic soils it increases to 18.1% and 168.9 t / ha, respectively. It is determined that the carbon content in the pine forest litter is quite stable and equals to 40 ± 1.4%, while its stocks range within 30–33 t / ha.

LAND CONVERSION INFLUENCE MONITORING FOR CO2 EMISSIONS ESTIMATION IN UKRAINE
Authors P.I. Trofymenko, V.V. Lyashenko, O.A. Tymoshchuk and N.V. TrofimenkoSummaryThis paper shows the results of in-country estimation of CO2 emissions for the period 1990–2017 and investigates the level of land conversion influence on the intensity of carbon dioxide emission or assimilation. It is shown that the most significant impact on the emission-assimilation balance is cause by the transformation of settlements and other lands into forest land, grassland and cropland. The research findings indicate a significant impact of land use type and management practices on the amount of organic carbon emitted from and sequestered by the soil, depending on their affiliation to certain lands. Determined that the revealed changes in the land structure are aimed at their gradual transformation from land with high anthropogenic load, primarily cropland, to conditionally stable land: forest land, grassland, which includes shrubs and wetlands. It is determined that for the studied period the total balance of two mutually opposite processes (emission and assimilation) is formed in favor of atmospheric decarbonisation and amounts to 68712.17 kt (13.6 kg/ha/year−1). It is shown that the conversion of various lands into forest land has had a significant effect on carbon dioxide binding and atmospheric purification, respectively, 47851.18 kt (177 kg/ha/year−1).

AGRO-ENVIRONMENTAL MONITORING OF THE APPLICATION OF MINERAL AND ORGANIC FERTILIZERS ON DRIED POLISH TERRACE SOILS
Authors V.I. Zatserkovnyi, N.V. Tsuman, P.I. Trofymenko, O.I. Bondar and A.D. BalayevSummaryThe influence of application of mineral and organic fertilizers on the productivity of crops on organogenic dried soils under climatic conditions of the Polissia region of Ukraine is considered. During the millennia of biocenosis and soil, nature and life have been maintained in nature. All living organisms are directly or partially interconnected. On this basis, we can conclude that soil is a sustainable living ecosystem. After the emergence in 1840 of Liebig’s scientific work entitled “Chemistry for use in agriculture” the theory of mineral nutrient regime of the soil emerged. It belongs to inorganic chemistry. The followers of this theory have also proved that plant nutrition is due to the complete decomposition (mineralization) of organic matter. It is known that the nutrient regime of the soil is formed due to the decomposition of organic mass. Of great importance is the particle size distribution, agrochemical and physical and other soil characteristics. According to scientists, the main chemical elements in plant nutrition are: carbon, oxygen, nitrogen, hydrogen, sulfur, phosphorus, silicon, calcium, chlorine, potassium, sodium, magnesium, iron and others. Some types of plants absorb more: iodine, aluminum, manganese.

USAGE OF GIS DURING THE MONITORING OF WASTES UTILIZATION AND SAVING
More LessSummaryThe problem of wastes utilization is one of the global problems of mankind. Environmental studies conducted during the recent decades in many countries around the world have shown that the growing destructive effects of anthropogenic factors on the environment have brought it to the brink of crisis. Continuous environmental pollution by solid, liquid and gaseous wastes from production and consumption, cause environmental degradation and has recently remained the most pressing environmental problem of social and economic priority. Effective monitoring of dynamically developing natural-technical systems requires reliable and up-to-date data about objects and processes in their territories, as well as advanced technologies of accumulation, processing and submission of information. Today the most objective and capacious source of spatial and semantic information about the state of the Earth’s surface and its objects are the Earth’s Remote Sensing materials.

GROUND AND SPACE COMPLEX MONITORING OF NATURAL AND ANTHROPOGENIC PHENOMENA AND DISASTERS
Authors O. Liashchuk, Yu. Andrushchenko, P. Topolnytskyi, A. Poikhalo and V. MamarievSummaryWars and local conflicts, nuclear weapons testing, the abuse of natural resources, greenhouse gases, forest fires, accidents at critical infrastructure facilities - all these are incomplete anthropogenic factors affecting the environment. An increase in population density and infrastructural complications make humanity increasingly sensitive to natural disasters such as earthquakes, tsunamis, and hurricanes. All this leads to constant challenges and threats to the national interests of states in the field of security and defense. Ukraine is no exception. To make timely decisions to prevent negative environmental changes and comply with environmental safety requirements, environmental monitoring systems are being introduced. Integration of monitoring types allows increasing its efficiency, operativeness and reliability. The first steps to creating such a complex system are carried out at the National Center for Control and Testing of Space Facilities (NCCTSF), combining methods of remote sensing of the Earth with ground-based geophysical methods of special control. Information received and processed as soon as possible is provided to state bodies. However, complex processing has not yet become everyday practice, although its relevance is constantly increasing. Possibilities of using monitoring methods during military depots explosions are shown.

PrylipkoSummaryThe development of the direction of modern civilization depends on the global transformation of information resources and the means of their use in all regions of the world. Recently, the information industry has become a new branch of the world economy, and has become an integral part of modern processes of globalization, which provides broad access to modern technologies, science and culture, and at the same time affects the transformation of mankind. In military science and practice, it is increasingly marked the tendency of the transition of the modern war to the strategies of indirect asymmetric actions, based on a combination of military efforts with political, economic and informational methods of influence on the enemy for solving problems previously solved mainly by direct military methods.

THE DEEP LEARNING APPROACH FOR PAN SHARPENING ASTER SWIR DATA
Authors R. Okhrimchuk, I. Tishaiev and V. ZatserkovnyiSummaryMultispectral satellite images are effective for solving a wide range of problems in the various application areas. In particular, ASTER spectroradiometer images recorded in the Short Wave Infra-Red (SWIR) and Thermal Infrared Ranges (TIR) ranges can provide the lithological mapping and mineralogical composition of rocks. The scale of the resulting maps is based on the spatial resolution of the recorded digital images corresponding to the sensor. The ASTER spectroradiometer corresponds to the thematic maps with 1: 100000 - 1: 500000 scales. The goal is to increase the spatial resolution (upsampling) ASTER images in the SWIR and TIR bands with saving their spectral characteristics. The problem is the inability to use most known Pan-Sharpening methods because of ASTER images specification. The stack of imagery does not have the appropriate high spatial resolution panchromatic reference image Using any image (from visible or near-infrared (VNIR) spectral ranges) as a reference is not a good idea because they contain the data captured in the narrow spectral range (only in green, or red, or infrared). Therefore, the applying of standard approaches causing significant distortion of the spectral characteristics of SWIR images after the Pan-Sharpening procedure. In this paper, the main idea is using Convolutional Neural Networks (CNN) and Deep Learning techniques for superresolution resampling Aster multispectral imagery. Accuracy assessment of proposed model shows better RMSE metric values (up to 50%) in the spectral characteristics of transformed images, as compared with standard pan-sharpening technics.

DETECTION OF DEFORESTATION AREAS USING SATELLITE IMAGES
Authors V. Romaniuk, D. Kukhtar, L. Dorosh, Ye. Ripetskyi and S. SerediukSummaryUsing the example of a mountainous cultivated land environment, we have shown the use of Earth Remote Sensing Data (ERS) technology to control the change of forest land area due to logging. It has been proved that the histogram characteristics of the RGB Quick Bird satellite image contain information on changes in forest land structure from “forest land” to “deforestation”. We have found out that due to the different texture of the “forest land” and “deforestation” images, their histogram characteristics, the zones of pixel placement, differ in brightness. An analytical dependence between the dynamics of the areas AS changes at the boundary between “forest land” and “deforestation” and the number of pixels AN per the extremum, is obtained. Its considerably high sensitivity has been shown which allows solving the problems of recording the change of forest land areas in the land resource structure using the characteristics of satellite imagery.

USE OF REMOTE FIELD MONITORING DATA TO PREDICT YIELDS AND RESOURCE MANAGEMENT WHEN GROWING WINTER CROPS
Authors O.A. Furmanets, O.I. Bondar, S.I. Veremeenko, P.I. Trofymenko and D.P. TrofymenkoSummaryThis paper presents the results of studies of the use of Sentinel 2A satellite imagery to control winter wheat vegetation in difficult conditions of a particular field, to predict the true yield of the field in the uneven crop development, or their damage due to adverse meteorological factors. It is established that, based on satellite images of NDVI, it is possible to predict the yield of individual sections of the field and crops in general. It is shown that using generalized performance maps can significantly improve the efficiency of material resources (seeds, mineral fertilizers, fuel) and the overall economic efficiency of crop production. It was found that it is advisable to use a cartogram of average long-term field productivity as a basis for planning differentiated fertilizer application.
