Typomorphic peculiarities are shown of upper Precambrian gold- bearing carbonaceous layers of the South Urals. A gold- concentrating role is established of sulfide-carbonaceous depositions and hydrothermal-metamorphic nature of metallization. A qualitative model of gold-formation is represented, proposing a multi-time extraction of gold from host rocks in the process of lithe- and tectogenesis.
