Oliinyk O. Reconstruction of paleotectonic conditions for the development of salt-dome structures of the central part of the Dnieper-Donets Deprеssion connection with oil and gas content.

In the dissertation the main stages of the development of salt structures located along the regional profile of the Bereznyaki-Nedrigaylov in different structural-tectonic zones of the Dnieper-Donets Deprеssion are studied: intersame sag of the Vysachkivsko-Romodanovskaya Anticline (southern flank zone), Skorobagatkovska Brachyanthicline (axial zone), Gerasimovskaya fold (northern flank zone). On the basis of the analysis of geological and geophysical materials using paleotectonic methods, the reconstruction of the formation of structures was performed by constructing geological sections, isopach maps, paleotectonic alignment charts, and graphs of sedimentation rates. According to the litho-facial method, correlation schemes were constructed to calculate the size of stratigraphic breaks and to determine the dynamics of structure development. According to graphs of sedimentation velocities, three main phases of the dynamics of growth of salt structures are identified - intensive, slow and passive. The salt structures of the central part of the Dnieper-Donets Deprеssion are systematized in relation to the zones of the region and the confinement of the roof of the salt core (caprock) to different stratigraphic levels and the presence of oil fields. Key words: Dnieper-Donets Deprеssion, Vysachkovу-Romodanivska аnticline, Skorobagatkivska structure, Нerasymivskа fold, structural-tectonic zones; salt structures, deep-breaks; faults, methods paleotectonic analysis, petroleum, traps hydrocarbon.
