Petrology interpretation of deep structure of Ingul'skyi megablok of the Ukrainian shield due to geophysical data

The analysis of inner structure of the earth crust of Ingul'skyi megablok of the Ukrainian shield is carried out, features and nature of anomalous change of deep parameters of surface of component parts of crust are established, degree of her maturity is determined. Favourable factors on different deep levels and the surface of basement,, which are "responsible" for transporting of mantle fluidsaturated melt to the surface and their spatial localization on the surface of basement are determined.

Construction of the geodynamic models of the seismic active regions of the earth (the Neftegorsk earthquake, Sakhalin island)

The constructed model for a deep structure of the lithospere under the Neftegorsk earthquake region shows that North Sakhalin consists of the North Sakhalin sedimentary basin, the Deryugin basin and the ophiolite complex located between them. The ophiolite complex composed of the the ultrabasic rocks, fixes the position of the ancient subduction zone which was active about 100-60 million years ago. On a surface the subduction zone manifests itself as deep faults running along Sakhalin.

Lithosphere heterogeneity of the Dnieper-Donets basin and its geodynamical consequences. I. deep structure

Purpose. To investigate lithosphere heterogeneity of the Dnieper part of the Dniper-Donets basin and its stages after 3D gravity and magnetic modeling using the data of DDS, seismic tomography, geological structure of the Precambrian basement, and sedimentary cover for subsequent geodynamic interpretation.

3D magnetic model of the Korsun–Novomirgorod pluton and its geological interpretation

The 3D model of the upper and middle crust of Korsun–Novomirgorod pluton using magnetic anomaly maps with scale 1:200 000, gravity modelling and DSS data have been created. The main feature of the pluton’s magnetic inhomogeneity is the presence of reverse magnetization, which is typical for gabbro-anorthosite complex. The asymmetry in the pluton’s magnetic structure distribution and in the deep structure of the crust relative to trans-regional Kherson Smolensk pushing zone has been detected.

Deep structure of the Kirovograd ore area according to geoelectric researches

The nature of anomalies of the high electrical conductivity on depths to 2,5 km is defined by regional metasomatic transformations of the soils conducting to formation of ore salinity (uranium, gold, diamonds). For the first time for the Kirovograd ore area the 2,5Dmodel of distribution of values of electroresistance to depth of 100 km by results of one-dimensional inversion of  MTS data is constructed. The three-dimensional geoelectrical model of Earth’s crust and the upper mantle of the Kirovograd ore area is constructed and specified.

3D geoelectric model of the Zmiyinyi island

Purpose. Construction of three-dimensional geoelectric model of the Zmiyniy Island and the nearby waters of the northern Black Sea shelf. Methods. Methodology. The methodology of research is directly linked to the procedure of the three-dimensional geoelectric model construction. It involves the selection of the spatial parameters of the model and its cells, and the model is built against the background of the "normal" one-dimensional geoelectric section in this area.
