Technology of Frequency Resonance Processing of Satellite Images: Results of Testing on gold deposits and areas of gold ore occurrences
Authors M. Yakymchuk, I. N. Korchagin and G. DrogitskayaSummaryThe results of testing mobile and direct prospecting technology of frequency-resonance processing of satellite images and photo images at large gold deposits Boddington (Australia) and Muruntau (Uzbekistan), as well as at areas of gold ore occurrences in Australia and Ukraine, are presented. At a large Boddington deposit, responses from gold were recorded up to 2600 m, and at the largest Muruntau, up to 2000 m. Within the Ilkurlka ring structure (Australia), gold ore mineralization intervals were recorded from the surface up to 2000 m. Within a prospecting site in Ukraine, responses from gold were obtained from intervals of 49–99 m and 590–650 m. All examined objects are located in the contours of deep channels (volcanoes) with roots at 470 and 996 km, filled with granites. In the contours of the Yarrabubba crater, responses at gold frequencies have not been recorded. Responses from gold were recorded only in granite volcanoes with roots at a depth of 470 km. The research materials, presented in the report, as well as those conducted earlier, will allow us to formulate statistically substantiated recommendations of a methodological nature for the search for fuels and ore minerals.

The use of geoinformation technologies for visualization the features of the underwater terrain of the Antarctic Territories and the geological processes which contributed to its formation
Authors M. D. Krochak, M. V. Bandurenko, V. I. Holoborodko and Y. I. VoropaiSummaryThe aim of the presented work is creating a 3D image of the seafloor of the northwest coast of the Antarctic Peninsula in the area of Argentine Islands at the location of the Ukrainian Antarctic station “Academician Vernadsky”. The bathymetric maps of the seafloor of this water area became the actual material. Depths of 730 points in the area of 5,6 km 2 were taken to create the database. ArcGIS methods of spatial analysis were used to create the 3D model: Arc Map 10.1.4, Arc Scene 10.1.4, and Surfer 10. The simulation results are compared by different methods. It was concluded that there is an undeniable advantage of the model built by Arc GIS methods, which give an idea of the smallest elements of underwater terrain. The main geological processes that have formed the modern morphology of the seafloor are the tectonics of fault character and the exogenous erosion glacial plowing processes, processes of the suspension flows that created the submarine valleys between the islands and canyons on the continental slope.

“Paleogeomorphological atlas” as a way to accumulate generalized and obtain new information «historical-dynamic morphosystem of the Earth»
SummaryNow the geomorphology object of the relief of the Earth is specified as a historical-dynamic morphosystem of the Earth.
The historical-dynamic morphosystem of the Earth continuously forms its own space-time - the geomorpholithosphere.
The historical-dynamic morphosystem of the Earth and geomorpholithosphere are studied mainly by paleogeomorphology.
An important task of paleogeomorphology is the development of paleogeomorphological mapping, which involves the creation of paleogeomorphological maps and their atlases.
When compiling paleogeomorphological atlases, theories and methods are directly and indirectly used: non-equilibrium thermodynamics theory, general systems theory, morphochronodynamic concept, morphochronodynamic analysis, regional geomorphological analysis, complex paleogeomorphological analysis, cartographic method, mathematical and statistical method.
There are sufficient conditions to create “paleogeomorphological atlases” of the terrains of the former USSR.
“Paleogeomorphological atlases” consist of the following sections: 1) explanatory text; 2) traditional paleogeomorphological maps; 3) a new type of maps built on a morphochronodynamic basis; 4) special maps for individual objects - traditional and “new”; 5) special maps that have theoretical and practical orientation.

Seven-year cyclicity manifestations in groundwater mode revealed by wavelet analysi
Authors O. Shevchenko, A. Skorbun and D. CharnyiSUMMARYStatistical methods, mainly wavelet analysis, showed the presence of 7–8 -year cycles of levels and runoff of groundwater in the Pivdennyi Bug river basin. These rhythms have been manifesting since 1989, which is the year of the beginning of significant climate change in Ukraine. These rhythms largely correspond to the rhythms of precipitation (8.7 years), river runoff and especially rhythms of temperature (8 years). It is also important that the cyclicity of 7–8 years in the GWL mode is practically not affected by local factors (degree of regulation, lithology, depth of the GWL, distance from the river, etc.), which significantly influence the rhythms of other periodicity. Instead, more regular cycles of 10–11 years, corresponding to the rhythms of solar activity, are almost non-existent after 1986. However, after 2003–2006, the daily GWL rhythm of 7–8 years (7.9 ± 0.6) also becomes irregular, which may be due to a new rotating meteorological phenomenon, which can lead to irreversible changes in the groundwater balance.

Using of Landsat space images to study the dynamic of coastline changes in the Black Sea north-western part in 1983–2013
Authors E. A. Cherkez, V. I. Medinets, T. V. Pavlik, Ye. I. Gazyetov, S. V. Medinets and T. V. KozlovaSUMMARYPurpose of the work has been to study different coastal areas’ growth/ reduction resulting from coastlines dynamics changes under abrasion and accumulation processes in the North-Western Black Sea (NWBS) influenced by natural and anthropogenic factors in 1983–2013. Methodology. LANDSAT space images of 1983–2013 and historical experimental data have been utilized as the initial and geological data for thisinvestigation. Processing has been done out using ArcGIS 9.2. Results. The results of study have shown that main areas with maximal changes of coastline location are river deltas (Danube, Dniester, Dnipro), as well as bay-bars of practically all the Black Sea limans (estuaries). Estimations of changes of coastal land areas’ increase (+)/ decrease (−) have been presented and discussed. Conclusions. Maximal changes of coastline position in the North-Western part of the Black Sea were registered in the Danube Delta, areas of the Sasyk and Dniester Limans and Odesa Bay. Land area in those locations grew by more than 16 km2. In other NWBS coastal areas decrease of land terrain was observed, i.e. destruction of coasts, which made about 5 km2. At that, it should be noted that the biggest changes were taking place in the past decade.

Use of spatial morphometric analysis of the Zmiinyi island underwater slope relief to reveal tectonic movements in Holocene
SummaryPurpose of the work has been to reveal the features of morphometric characteristics of modern relief of the Zmiinyi Island underwater slope in order to identify the stages of geological development and assess intensity of vertical tectonic movements in Holocene. Methodology. Nautical charts and results of bathymetric surveys down to 30–35 m depth performed in 2009–2015 using echo sounder have been used as the source data for the digital model of underwater slope’s relief. Using the digital model of sea, bottom depths hypsometric curve has been built to establish the generalized values of abrasion benches location depths (used as indicators of ancient coastlines), map of the island underwater slope inclinations and amplitudes of abrasion benches displacement have been determined to estimate the size, sign and speed of vertical tectonic movements. Results. From absolute values of modern depths and ages of abrasion benches, relative deformations of primary horizontal levels of abrasion benches caused by tectonic displacements have been calculated. It has been shown that average speed of relative tectonic movements with negative sign in the north-eastern area of the island in Holocene used to make 0.75 mm/year. Conclusions. Morphometric analysis of the detailed bathymetric studies has revealed correspondence of hypsometric levels of coastal benches between the north-western Black Sea shelf and the Zmiinyi Island underwater slope, which evidences the connection of certain stages of geological development of the Black Sea and the island in the time of Holocene transgression. Assessment of relative deformations of primary horizontal levels of abrasion benches caused by differentiated tectonic displacements of separate blocks has been presented.

Authors A. Kushnir, T. Burakhovych, V. Ilyenko and B. ShyrkovSummaryAccording to the research, the geoelectric heterogeneities in the earth’s crust and upper mantle of Ukraine were revealed, they are characterized by the anomalously low and anomalously high electrical resistivity values. The conductivity zones that reach the surface are characterized by the subvertical heterogeneity and assemble the galvanically linked system. It spatially coincides with the deep faults of the different rank that are distinguished according to the geological data. The earth’s crust independently of the geological and tectonic region is characterized by anomalous conductivity layers, the upper edge of which is observed at the different depths from 2 to 20 km with an apparent resistivity up to 100 Ohm∙m. The geoelectrical heterogeneity of the upper mantle was revealed in the Pre-Dobrudja and Crimean-Black Sea regions, and only fragmentarily under the Ukrainian shield, the Pripyat depression, and the Dnipro-Donets basin. The paper is with the explaining of the high-electrical conductivity anomaly nature based on the results of the geological and geoelectrical data complex analysis and their study as one of the factors of the geodynamic processes for the ore mineralization and hydrocarbon search.

Authors L. Dubis, N. Habchak, S. Bortnyk, V. Zatserkovnyi and Yu. AndreychukSummaryThe purpose of this study is to create a unified geodatabase of containing information on relict (continental) dunes. Continental dunes are widespread in Eurasia and North America. In the studies by many authors, a considerable amount of information regarding the distribution of continental dunes, their morphology and lithology of sediments has been obtained. This information requires unification and systematization. The study proposes the structure of the “Relict continental dunes” multilevel geodatabase. The principle of territorial display of aeolian forms has become a priority in concept of geodatabase development. The geodatabase consists of five major relational multilevel blocks. The advantage of proposed geodatabase is the coverage of a large amount of information about the objects under study and ability to quick analysis it with the spatial display of the research object. The main tool for building the geodatabase is ArcGIS Desktop 9.0. The geodatabase structure uses a variety of RS and cartographic data processed by GIS, field surveys and laboratory analysis methods. Overall, geodatabase contains systematic, geocoded and layered raster, vector and text, data types in SHP, MDB, GRID/IMG, and TIN formats.

Methods for mapping and assessment drivers of change effects on terrestrial and marine ecosystem services in Lithuania
Authors E. Gomes, M. Inácio, K. Mikša, M. Kalinauskas and P. PereiraSUMMARYDifferent mechanisms drive marine and terrestrial ecosystems changes. The present study aimed at presenting a conceptual methodology to map marine and terrestrial changes, to recognize their drivers of change, and to measure the impacts of land management in Lithuania. To model changes in the terrestrial part a Cellular automata-Markov chain approach is proposed for the following four scenarios: business as usual; urbanization; land abandonment; and agricultural intensification. To measure its impacts the InVEST habitat model is endorsed. For the marine part, changes will be addressed in land and in the sea applying driver specific approaches. The outcomes can provide decision-makers anticipate futures uncertainties.

Seismic tomographic model along the geotraverse VI profile
Authors D. V. Lysynchuk, L. V. Farfuliak, K. V. Kolomiets and O. V. KolomietsSummaryThe reinterpretation of the “old” seismic data along the line of the 900 km long geotraverse profile is represented by a seismic tomographic model. The bitmap images of the original seismic data were converted into vector diagrams by the DIGITIZER computer program. This made it possible to represent the hodographs as numerical data sets and to construct the seismic tomographic model along the geotraverse line. The velocity model is obtained by the tomographic inversion method of first arrivals of seismic waves. The deep tectonic structures are clearly outlined on the tomographic model. In particular, the Ukrainian Shield is characterized by Volyn, Podolsk, and Bug Megablocks with uplifts of variable sizes in the upper and middle crust. The Golovanivska suture zone is distinguished as uplift from the northwest to the southeast and the Kryvorizka suture zone is highlighted in the opposite direction.

Using the TAR3D program for 3D data visualization in geoelectric studies
Authors V. N. Tarasov and I. M. LogvinovSummaryIn recent years, actively developing programs for three-dimensional data visualization. There are no such areas of life where 3D images are not needed. As a rule, available programs do not always provide the opportunity to get the image in the desired form. Therefore, to build three-dimensional models, in addition to widespread and well-known GIS products, the authors of the report offer their alternative solution. In the Matlab environment, which is a high-level language was written TAR3D program for three-dimensional data visualization. The program was tested on geoelectric data obtained within Ukraine and abroad. The operational experience of the program shows that it is suitable not only for deep geological and geophysical data. The process of building complex 3D models is simple. The block design of diverse objects mentioned in the text is used. The final model is saved in vector form with the ability to continue interactive graphic editing. The rotation of the model in any direction, the use of a coordinate marker on the body of objects gives an undeniable advantage for researchers who are engaged in the analysis of three-dimensional objects.
