Abstract
Geological and geophysical evidence reveals a tectonic (rift) origin of the junction of the Arctic Uralian orogen with pre-Jurassic complexes of the West Siberian Plate. The available data allow an idea of the relationship between the Ural and Pai-Khoi structures. The Hercynian Uralian complexes are bounded by an arcuate deep fault in the north at the termination of Baidaratskaya Bay and contact the Kimmeridgian (?) Pai-Khoi fold com- plexes in the west. The study territory may store oil and gas in Permian (Permian-Triassic) reservoirs.
