Formations of the Carboniferous-Lower Permian carbonate deposits of the Upper Pechora basin (Northern Urals)
The Upper Pechora basin is part of the northeastrn margin of the European Platform. In the Paleozoic, it was located within the carbonate shelf of the passive continental margin. According to A. I. Eliseev, Visean terrrigenous-carbonate (platamovy type) and Upper Visean-Lower Artinskian carbonate (k...
