Problem of modern transport systems and its structural elements
Authors O.V. Kobrin, V.I. Zatserkovnyi, P.D. Krelshtein and L.V. TustanovskaSummaryModern large cities and megalopolises are constantly facing transport problems that require finding the right, automatized solutions. Difficulties connected to the admission of high-intensity traffic flows increase through a large number of pedestrian flows. Increasing the number of individual cars and changing the structure of the city causes on top environmental problems and problems of road condition and quality.
The main instrument of traffic management is colour light signaling, designed for the first pass of road users through a certain section of the UDM, and also for determination unsafe sections of streets (roads). The structure of modern automatized traffic management systems (ASM-T) is built on the hierarchical principle of information processing, which while identifying the total management system should operate, foresees the allocation of several mutually subordinate management levels: local, zonal, district, citywide.
Transport models based on modern information technologies are powerful computational software complexes that, based on the functional and spatial characteristics of a city, together with all existing data, calculate the most likely distribution of transport and passenger flows by of the street-road network (UDM).
Effective resolution of transport network problems is to be solved with the help of geo-information analysis and geo-information modeling, namely through building a transport model of the city with the help of geo-information systems.

The influence of geophysical factors on air temperature in Antarctica
Authors V. Bakhmutov, N. Kilifarska and G. MelnykSummaryThe analysis of the created distribution maps of the geomagnetic field and the atmosphere characteristics allowed us to developed a model that adequately explains the changes in the current Antarctic temperature – simultaneous “heating” in the west and “cooling” in the center and in the east. It is a chain of cause-effect relationships: the geomagnetic field – the flux of solar protons – the concentration of ozone – the temperature and humidity near the tropopause – the surface temperature. The reduced intensity of the geomagnetic field in the Western Antarctica results in a systematically low concentration of ozone and increased humidity on the tropopause, which facilitates the retention of long-wave radiation from the Earth in the troposphere due to the greenhouse effect and an increase of the surface temperature. The increased intensity of the geomagnetic field and ozone concentration in the Central and Eastern Antarctica cause an increase in temperature and a decrease in humidity at the level of the tropopause, which does not prevent the penetration of long-wave radiation from the Earth upwards and causes cooling of the lower troposphere. Taking into account the geomagnetic field as a factor of influence on the climate allows us to adequately explain the found differences in Western and Eastern Antarctica.

Monitoring of geomagnetic induction vector
Authors V.I. Babak and I.I. RokityanskySummaryOne of the goals of geoinformatics is the creation of databases of geophysical fields observations and calculated from them response functions of the Earth. International database “Intermagnet” keeps values of geomagnetic field since 1991 measured at world-wide network of geomagnetic observatories. From these rough data the induction vector C (one of response functions of real Earth to applied geomagnetic field) has been calculated for all observatories for all years presented in “Intermagnet” that constitutes new database with time reading 1 day and 1 month. C carry information on electrical conductivity anomalies in the Earth’s interior and their temporal variations. Scientific part is concentrated on annual and 11-years C variations analysis.

3D thermal model of the Trøndelag Platform, Møre and Vøring basins (the Mid-Norwegian continental margin)
Authors Y.P. Maystrenko and L. GernigonSummaryA 3D temperature distribution beneath the Trøndelag Platform, the Møre and Vøring basins of the Mid-Norwegian continental margin and adjacent areas of the continent has been obtained based on the recently constructed lithosphere-scale 3D structural model of the studied region. There is a clear correlation the between the major tectonic elements of the continental margin and the modelled temperatures, showing an increase of the calculated temperatures from the continental lithospheric domain towards the oceanic one. The modelled temperature is highest within the Vøring Basin where a thermal insulation of the sedimentary cover increases the heat storage within the areas where low thermally conductive sedimentary rocks are relatively thickest. The Møre Basin is represented by lower temperatures compared to the Vøring Basin where the sedimentary cover is the thickest one. The Trøndelag Platform is characterized by even lower modelled temperatures, reflecting a fact that this area was less affected by crustal thinning and has thinner sedimentary infill. The modelled temperatures are representative for the subsurface regional-scale 3D conductive thermal field and show a general good fit with the temperatures measured in the available wells.

Numerical and Laboratory Examinations for Digital Rock Modeling for Clastic Oil and Gas Reservoirs
Authors V. Berezovsky, I. Belozerov, M.G. Gubaydullin and A. Yur’evSummaryPetroleum well cores examinations are among the most costly stages of development of oil and gas. And even a partial its replacement by the numerical experiments can provide significant economic benefits. 3D-reconstruction of the core microstructure can be considered as a cheap and least timeconsuming method for obtaining petrophysical information about the main filtration-capacitive properties and fluid motion in reservoir rocks. One of the promising approaches to build the mathematical model of the macroscopic properties of porous media and for the 3D-reconstruction of the rock microstructure is the method of molecular dynamics. This work presents the results of numerical calculations and their comparison with the full-scale examination.

Density modeling of the south-eastern part of the Fennoscandian shield using GIS Integro
Authors N.V. Sharov, N.N. Pimanova and V.A. SpiridonovSummaryWhen studying the deep structure of the southeastern part of the Fennoscandian shield, maps of the topography of the Moho surface were clarified. The depths of this surface on maps and sections of GSS profiles were compared. Discrepancies (up to 8 km) were taken into account in the construction of the consolidated map. To correct the position of this surface in the space between seismic profiles, an approach using the analysis of 3D distribution of density inhomogeneities in the earth’s crust and upper mantle.
The results of 3D density modeling for a two-layer model (earth’s crust-upper mantle) made it possible to determine the position of large blocks with different density in both of the layers.
2D inverse gravitatione problem solution in block model along the seismic profile of the Baltic sea under the assumption of lateral heterogeneity of the mantle made it possible to obtain more realistic densities for the lower crust of the Svekofennian folded area and for the upper crust of the Karelian block.

To the issue of the border kinematics of the adjacent plates
More LessSummaryThe relative motions of lithospheric plates are traditionally regarded as spreading, subduction and transform. Surveying data show a much greater variety of combinations. Purpose of the work is to identify the complete set of possible relative movements of plates. A new methodological approach is used. It consists in the fact that it was analyzed the movement of both plates relative to their border. This approach required additions to the structural-geological terminology. It made possible to formalize the orientation of the plate movements. 8 variants for the movement of the plate relative to its boundary were selected. In combination with eight of the same variants of the opposite plate motion, 64 combinations are obtained. There are 36 unique variants of combinations. 8 of them are well-known, 4 reflect the variants of displacement of inactive boundaries, and 24 are new to geodynamic theory. For 18 new variants, areas of their modern implementation in different regions of the world are shown; 6 more variants have not been found yet. The obtained result allows us to proceed to the analysis of interaction of multidirectional mantle flows.

Electromagnetic studies of the central part of the southern Dnieper-Donets Basin slope
Authors A.M. Kushnir, V.A. Ilyenko and V.B. DzhaoshviliSummaryThe simultaneous MT/MV studies were carried out along the Neseno-Irzhavets-Abramovka profile to study the deep structure of the lithosphere to search for electrical conductivity anomalies that may be caused by the fracturing of the rocks through which the fluids migrate and possibly create hydrocarbon deposits. The new modern experimental electromagnetic parameters described in this paper should detail the Kirovograd electrical conductivity anomaly and become the basis for the three-dimensional model construction in such complex geological environment as uneven-aged structure junction. The described experimental MT/MV observations confirm the deep anomalous structures that investigated in the previous years.

Geoelectric researches of the Tarasivka structure of the Golovanivsk suture zone
Authors A.M. Kushnir, T.K. Burakhovych, V.A. Ilyenko and B.I. ShyrkovSummaryAccording to the results of 3D modeling, the Tarasivka structure is fragmentarily manifested as a low resistivity, the conductive zones with different resistivity cross it in a sublatitudinal direction, in which the lowest values from 10 Ohm⋅m in the south to 100 Ohm⋅m in the north are in its contour. In the vertical section it can be represented in several layers: the first one is the conductor with ρ = 10–250 Ohm⋅m — from the surface to 10 m −100 m, most likely linked not only with high electrical conductivity of surface sediment deposits, but also with the zones of disintegration of rocks of the basement; the second - a high resistivity layer with ρ = 10000 Ohm⋅m — from 100 m to 2 km, possibly it is represented by the uniform non-differentiated thickness; the third layer is the electrical conductor with ρ = 10–250 Ohm⋅m from 2–3 km to 10 km, probably linked with the special composition of the earth’s crust at these depths (graphitization, sulfidization, etc.) or fluidization of different origins, more often it is considered according to the modern data that the nature of the conductive anomalies is the result of the joint influence of the electron and ion types of electrical conductivity.

Local features of the gas volcanism and regional deep hydrocarbon system in the Shenhu area (northern continental slope of the South China Sea)
Authors V.D. Soloviev, I. Korchagin, S. Levashov, N. Yakymchuk and D. BozhezhaSummaryNew anomalies of “gas hydrates reservoir and gas deposit” types in the drilling Shenchu area (South China Sea) were revealed by the frequency-resonance technology of the satellite images processing and decoding. The local area with very high reservoir pressure values of 67 MPa – possible vertical channel for deep gas bearing fluids migration – was detected. Diapers and mud volcanoes can have deep roots in the form of disturbances and fracture zones at the base of the sediments and near the basement. They may be connected both with deep sources of thermogenic methane and with shallow biogenic hydrates, since the nature of the occurrence of gas hydrates indicates their migratory character. Thermogenic gas in local structures of the Shenhu area possibly connected with vertical and lateral fluid pathways from a depth of 5 – 15 km, where the favorable conditions for the intermediate reservoirs of the abiogenic methane are existing. The obtained results confirmed the presence of the regional hydrocarbon system in local features with gas hydrates in their structure, which formed here in process of gas emanating along lateral fluid pathways from mud volcanoes and diapers with deep roots.

Geological position and age of Argentine Islands mafic dykes, West Antarctica
Authors L. Gavryliv, O.V. Mytrokhyn, V.G. Bakhmutov and A.G. AleksieienkoSummaryBased on the recent field geological research combined with previous isotopic datings, it is shown that numerous mafic dykes, occuring among the Mesozoic-Cenozoic igneous rocks of the Argentine Islands and the adjacent territory, are formed during at least two stages. The Mesozoic stage of dykes formation is represented by the Cretaceous dykes of porphyritic microgabbros and microdiorites, which intrude the orogenic formations of the UJVG. Although, it is impossible to exclude the presence of even more ancient dykes genetically associated with UJVG. The Cenozoic stage, apparently, includes the dykes of several age groups. Among them, a significant place is occupied by the youngest dykes, which intrude the Cretaceous-Paleogene granitoids massifs after their final exhumation. The presence of such dykes indicates that magmatic activity in the region did not ceased in the Neogene, and possibly in the Quaternary. The subvolcanic features of these dykes allows to raise the question of finding coeval volcanic formations with the same age.

Assessment of the quality and reserves of graphite of the South-Eastern area of the Zavalevsky deposit by block modeling
Authors V. Demidov and I. BersymSummaryThe paper presents the results of the analysis of carbon graphite content with the identification of the most high-quality ore-bearing zones for North Zone (the South-East area) of the Zavalivsky deposit. The authors give an analysis of the ore deposit of graphite gneisses according to data testing during exploration works of 1971—1982 years, taking into account the degree of working areas. In particular, 2514 ordinary samples were analyzed for 121 wells. In addition, the total amount of graphite ore reserves was calculated by the block modeling method and a comparison with the classic reserves calculation was carried out — by the section method. The block model of the ore bodies within the wireframe model using the interpolation by the inverse weighted distances method (IDW) was used to estimate the reserves.

Modeling Permian sediments erosion in the Dnieper-Donets Basin
Authors I. Streltsova and I. VirshyloSummaryThe aim of this study is modeling Permian deposits erosionof the Dnipro-Donets depression. The Perm system is characterized by intensive tectonic and climatic changes, that influenced paleodepositional environment. Permian deposits are represented only in the Asselian, Sakmarian and Artinskian stages in the Dnieper-Donets Basin. Deposits of the Guadalupian and Lopingian series are eroded. The Permian system is represented by terrigenous sediments, which gradually changed by homogenic, and then eroded. Schlumberger software PetroMod 1D was used for simulation. As a result, three burial history models were obtained. Each model reflects different intensity and time when erosion occurred. The most likely model was chosen based on the history of the basin development.

More LessSummaryModern experimental researches on the study of the natural low-frequency electromagnetic field of the Earth with the use of modern equipment, processing of their results based on universal program packages and interpretation (including on a qualitative level) can provide detection of electric conductivity anomalies and the research of the deep structure of the Earth’s crust and mantle. The deepest point of the MTS village Ridne characterized by complex geological-tectonic structure and located in the northern part of the Scythian Plate, in the Sivas through between the Chongar and Melitopol-Novocaritsyn defective zones. The qualitative interpretation of the depth curves of the MTS indicates the possible presence of a conductor with a boundary of the upper edge of 50–100 km and S about 3000–5000 S. The total longitudinal conductivity of the sedimentary layer along the ascending branches ρa reaches over 400 S. The length of observation in the field is systematically substantiated. points of the MTS for the Sivas Through region and it is concluded that in order to obtain the curve ρa with stable S and H, the duration of observation should be no less than three days, while for S component it will be enough for one day.
