The reconstruction of the neotectonic pattern is ascribed to the Pleistocene sheet glaciations. The main geomorphic features of W Siberia are considered as created by Pleistocene ice sheets or by glacioisostasy. The adjacent mountains are supposed to be compensation uplifts that developed around the central isostatic depression of the coastal lowlands. The glacial loading apparently caused the spatial separation of oil and gas reserves. Possible influences of glaciotectonics on reconnaissance of structural traps are discussed. -from English summary
