摘要
Zoning is based on the provided geological and geophysical data, subject to the availability of three multilevel regmatic systems of inclined and shear discontinuous faults in the Earth's upper crust, formed as a result of the Neogene-Quaternary geodynamics of uneven bilateral horizontal compression. The developed geotectonic map displays a double-level geological environment with a relatively hard base and a more plastic covering thickness. The lower level is represented by a combination of isometric and linear heterogeneous blocks located at four hypsometric levels. The upper level is represented by a smooth aggregate of blocks, separated by large rupture anomalies or flexural fault zones. Individual blocks of Paleozoic fissured rocks with overlapping deposits that are subject to slight compression or stretching, and are located on hydrocarbon migration paths from oil and gas generation centers collected in Paleozoic rift systems, can be considered as possible oil and gas prospect objects.
