Formation Conditions of the Lower Carboniferous Volcanoterrigenous Sequences of the Eastern Slope of the Central and Northern Urals
摘要
Abstract
The Lower Carboniferous volcanoterrigenous sequences of the eastern slope of the Central and Northern Urals are studied. It is shown that these rocks are confined to zones of regional strike–slip faults and formed under transtension conditions. The geochemical parameters of volcanic rocks are similar to those of igneous rocks of both suprasubduction and intraplate settings, which is in agreement with ideas about their formation in the rear of the active continental margin.
