COMPOSITION OF GOLD AND FORMATION CONDITIONS OF ORES FROM THE KOPTO HYDROTHERMAL DEPOSIT (NORTHEAST TUVA)
The mineralogical and geochemical peculiarities and formation conditions of gold are considered for the Kopto gold stockwork deposit juxtaposed on skarns and metasomatites of the Tardan gold cluster (Northeast Tuva). Gold mineralization is confined to granite-porphyry dikes of the Early Ordovician E...

| description | The mineralogical and geochemical peculiarities and formation conditions of gold are considered for the Kopto gold stockwork deposit juxtaposed on skarns and metasomatites of the Tardan gold cluster (Northeast Tuva). Gold mineralization is confined to granite-porphyry dikes of the Early Ordovician Early Tannuola complex and associated beresite-listvenite metasomatites. In composition of productive mineral assemblage, the Kopto with electrum, acanthite, native bismuth and barite deposit belongs to gold-pyrite-chalcopyrite type. The fineness of native gold varies from 969 to 524 (802, on average). According to the fluid inclusion data, the gold-sulfide-quartz veins were formed at 230–165 °C from NaCl–H2O, NaCl–KCl–H2O and MgCl2 –H2O fluids with salinity of 4– 8 wt. % NaCl equiv. |
