Geochemical specialization of terrigenous deposits of the Bashkirian meganticlinorium

Abstract

The materials on the geology and geochemical specialization of Riphean terrigenous rocks of the Bashkirian meganticlinorium, including carbonaceous shale and conglomerate, are reported. Conglomerate is characterized by a high concentration of Au and PGEs mostly related to intensely dislocated zones. It is concluded that potentially ore-bearing zones in terrigenous deposits of the Bashkirian meganticlinorium were formed as a result of multistage polygene processes controlled by the Riphean–Vendian geodynamic evolution of the region.
