Bismuth Sulfosalt Mineralization in the Ores of the Vladimirskoe Deposit (Eastern Sayan Mountains)

Abstract The authors have for the first time identified gold–bismuth sulfosalt mineralization at the Vladimirskoe gold deposit (Eastern Sayan Mountains). This mineralization is unique to the southeastern part of the Eastern Sayan Mountains. Various Bi, Pb, and Ag sulfosalts, and native bismuth and silver have been found in the ores, forming peculiar mineral intergrowths with gold. It is evidence of the complex genesis of ores and the possible involvement of polymetallic melts in the processes of concentration and redistribution of gold and silver. The mineralogical and geochemical characteristics and structural features of the ores point to a metamorphogenic hydrothermal type of mineralization. The development of ore mineralization may be related to accretion–collision processes that took place in the Paleozoic.
