摘要

摘要研究了乌拉尔中部和北部东坡的下石炭统火山土著岩序。研究表明，这些岩石局限于区域性走向滑动断层带，是在张斜条件下形成的。火山岩的地球化学参数与板上和板内环境的火成岩相似，这与它们在活动大陆边缘后部形成的观点一致。

Formation Conditions of the Lower Carboniferous Volcanoterrigenous Sequences of the Eastern Slope of the Central and Northern Urals

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.
