Lithosphere heterogeneity of the Dnieper-Donets basin and its geodynamical consequences. II part. Geodynamics interpretation

Aim. Geodynamic interpretation of previously obtained 3D density and magnetic modeling results, and data on consolidated crust fault tectonics of the Dnieper part of Dnieper-Donets basin (DDB) in the light of its formation mechanism.

The map of vertical Holocene movements of Volyno-Podillya and Pre-Carpathians

The mapping approach based on revealed property of the geodynamical memory of actual soil cover (Holocene) is realized. Structure and facies of the soil cover are considered as a new information donor about the relief dynamics. The raw of tectogenic evolution of the soil-forming processes and the soil types in the range from subsidences to stable regime and elevations with different intensity is determined. For the Western Volyno-Podillya and Pre-Carpathian foredeep the calibration raw “soil type – total amplitude of vertical movements” is justified.

Estimation of the Earth crust strain rate tensor from GPS observations data in the Eastern Europe

Estimated from GPS observations velocities of GPS-stations were used to obtain 2D-model velocities and strain rate field in the Eastern Europe. The study of the velocities field in the region was done in a few steps. The first one consists of the development of the finite element approach on the geosphere based on bicubic spline functions and least squares collocation method for the interpolation scattered GPS-data to the regular nodes. The second one represents the inversion of velocities from GPS-observations to the strain rate tensor.

Lithosphere heterogeneity of the Dnieper-Donets basin and its geodynamical consequences. Part 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.

Geodynamic and geophysical effects in the physical models of interactions between the Earth’s structural shells

Perspectives of the creating of the new physical models concerning the structure of the Earth, their evolution and methodology of the structure classification and parameter measuring of the Earth’s physical fields are analyzed. It is pointed out that investigation of the deep structure, composition and geodynamics of the continental and oceanic lithosphere gives the possibility to distinguish the system connected with global processes of Earth’s development (rifts, uncompensated deeps, continents, oceans). 

Geodynamics, tectonics and seismicity of Carpathian region of Ukraine

Purpose. The purpose of researches – to analyze the characteristics of modern geodynamics, tectonics and seismicity of Carpathian region of Ukraine and its components – the Folded Carpathians, Transcarpathians and Precarpathians. Methodology. The methodology includes a detailed complex analysis of the deep structure and seismotectonic activity in the region and its separate zones on the basis of specially developed methods of refinement the coordinates and depth of local earthquakes sources and complex of geological and geophysical data. Results.

Dynamics of postseismic tectonic deformations

Aim. The purpose of researches – continuous monitoring observations of geophysical fields, determined by the need of fundamental and applied geophysics and geology for reliable and detailed regional data on the behavior in time and space components of geophysical fields generic modern dynamics of the earth's crust, especially in seismically active regions. Such data are also needed to evaluate the durability and reliability of critical and dangerous geological and geotechnical hazards.

Geophysical insights on the structure and geodynamic evolution of the se Carpathians and related foreland in the context of the Black Sea opening

The paper brings into discussion geophysical evidence for jointly explaining the unusual craton seismicity in front of the SE Carpathians and the upper mantle intermediate-depth earthquakes in the Vrancea zone within the frame of the geodynamic environment generated by the W Black Sea opening and further evolution of the lithosphere expelled towards NW by rifting.

 

Ukrainian Carpathians in the structure of pancardi (magmatism and geodynamics)

Purpose of investigations – to ascertain the position of Ukrainian part of the Carpathian geosyncline in the common structure of the Pannonian-Carpathian-Dinarides region (Pancardi) at different stages of the development. Methodology. Integrated analysis of the peculiarities of different-age magmatism together with other geological-geophysical material and reconstruction of the structure and geodynamics of both the whole Pancardi and the Ukrainian Carpathian in particular at different stages of alpine development. Findings.
