The History of the Early Carboniferous Gabbro–Granite Formation (Southern and Middle Urals)

Abstract

This work presents new data on the geology and petrogeochemistry of the Magnitogorsky, Neplyuevsky, and Kanzafarovsky rock complexes. It has been proven that these complexes belong to a gabbro–granite formation. These data provide allow combination of the Southern Ural and Middle Ural segments of the Early Carboniferous suprasubduction rift zone into a unified submeridional structure, which was formed in the Devonian back-arc basin. This structure was thrust over the western margin of the East Uralian Uplift at the collision stage of the development of the Southern Urals. The Cu–Mo specialization of granitoids of the Magnitogorsky and Neplyuevsky complexes was revealed.
