Regularities in the orientation of bottom lineaments and faults in the Russian segment of the Sea of Japan

The configuration of the lineament-disjunctive network in the Russian segment of the Sea of Japan (sheets K-52 and K-53) was studied with structural zoning of the region using geophysical and geomorphologic data. The constructed rose diagrams revealed systematic orientation of lineaments and faults in the region as a whole and some of its areas. The orientation of linear structures in the Russian segment of the Sea of Japan is compared with that characteristic of the global disjunctive network. This allowed the following inferences: (1) the region is characterized by a single lineament-disjunctive system with four main directions of dislocations: submeridional (0–5°), sublatitudinal (86–90°), diagonal northeastern (36–65°), and diagonal southeastern (136–140°); (2) the directions of these dislocations coincide with the orientation of four main systems in the global disjunctive network (planetary fracturing); (3) the revealed disjunctive network is substantially of the Earth’s rotation genesis; (4) regularities in the distribution and orientation of faults and lineaments are determined by two interacting factors: the stress concentration in areas of the layer thickness gradient and variations in the Earth’s rotation velocity (the former controls localization of faults and the latter, their orientation).
