Based on the gravity-magnetic and seismic data, which indicate the differentially oriented tectonic deformations, there were determined the extensive distortion zones within the Paleozoic basement. The strike direction of the zones is coherent with the major areal of tectonic deformation directions. The geological structure model of Paleozoic basement, designed on the basis of lithological and geophysical investigation results, revealed a reversed morphostructure of erosion-tectonic protrusion: the uplifted basement block coincides to the structurally complex and fractured tectonic deformed blocks of syncline folds with steep dip in the north-east direction and gentle dip in the south-west direction.
