Substance and fluid sources in gold sulfide mineralization of the Auerbakh volcanic-plutonic belt in the Northern Urals

The data on C, O, Sr and S isotope composition of the carbonates, quartz and sulfides from the Tamunier and Vorontsovsk gold-ore deposits, localized in the Auerbakh volcano-plutonic belt are cited. It is established that on mineral isotope characteristics the nearest analogue of mineralization in beresites of the Tamunier deposit is the gold-polymetallic mineralization in jasperoids of the Vorontsovsk deposit. Calculation of the C, O and S isotope composition of the ore-bearing fluid testifies to a participation in ore-formation of two main substance reservoirs - the rock (sea carbonates and biogenic pyrite of host volcanogenic-sedimented series) and the fluid one (metalliferous magmatogene, as well as metamorphogenic fluids connected by the intrusive mass injection).
