Abstract

The geodynamic origin of volcanic and sedimentary rocks of the Upper Precambrian Arsha Group of the western slope of the southern Urals is considered. It is shown that both rock types are riftogenic/plume in origin. The problem of the spatial and temporal correlation of the Arsha and Karatau groups requires further study.
