GEOLOGY OF THE UPPER KAMA DEPRESSION IN THE NORTHEASTERN VOLGA-URAL ANTICLISE

A change in geology of the northeastern Volga-Ural Anticlise from the Precambrian to the Jurassic, in particular the Upper Kama Depression, which became part of the Glazov Depression in the Permian, is traced. The configuration of domes and depressions on the up-to-date tectonic map (base map of oil and gas geology) corresponds mainly to the geology of the major oil and gas complex, which is Lower-Middle Carboniferous in the studied area. New data on the stratigraphy of the Urzhumian and Severodvinian stages of the Permian system in the eastern Volga-Ural Anticlise are given, which confirm the Urzhumian (Belokholunitskian) age of the Ocherian tetrapod fauna. To predict stratiform manganese peroxide ore in the studied area, it is recommended to use the proposed structural-tectonic map based on the geology of Middle-Upper Permian and Mesozoic deposits.
