The environment of forming of Lower Carboniferous volcanogenic-terrigenous strata of the eastern slope of the Middle and Northern Urals

The Lower Сarboniferous volcanogenic-terrigenous strata on the eastern slope of the Middle and Northern Urals have been studied. It is shown that these formations are confined to the zones of regional strikeslips and were formed in the conditions of transtension. The geochemical parameters of volcanites show similarities with igneous rocks of both suprasubduction and intraplate environments, which does not contradict the ideas about their formation in the rear of the active continental margin.
