A NEW TYPE OF NOBLE METAL MINERALIZATION IN TERRIGENOUS ROCKS OF THE SHATAK GRABEN, WESTERN SLOPE OF THE SOUTHERN URALS

Abstract

The paper presents materials on a new (unconventional for the Urals) noble metal (platinum-gold-iron oxide) mineralization confined to terrigenous sequences of the Middle Riphean Mashak Formation on the western slope of the southern Urals. The mineralization is related to the percolation of reduced mantle fluids into upper levels of the crust at early stages of riftogenesis, their inversion in the crust, and redeposition of oreforming elements. © Pleiades Publishing, Inc. 2006.
