Title: ORE MINERALOGY OF THE KEDROVSKOE GOLD DEPOSIT (MUYSKY DISTRICT, REPUBLIC OF BURYATIA, RUSSIA)
Abstract: Ore mineralogy of the largest quartz vein Osinovaya at the Kedrovskoye gold deposit has been studied. Three stages of mineral formation are identified: marcasite-pyrrhotite-pyrite, gold-polysulphide and hypergenic ones. Native gold belongs to gold-polysulfide stage and is represented by two generations. The earlier high fineness (600–870, prevails 780–820) generation cements fragments of pyrite grains and forms inclusions in pyrite, and the later low fineness (520–580, prevails 540–580) generation associates with sphalerite-chalcopyrite-galena veinlets in pyrite. The disappearance of arsenoan pyrite, the increase in iron content of sphalerite, the change of pyrite to pyrrhotite with depth is noted.
