| 摘 要： | 包村和朝山金矿床位于安徽铜陵狮子山矿田，成因上属于矽卡岩型金矿。矿相学鉴定和电子探针分析结果表明，两矿床中的铋矿物以自然铋、辉铋矿为主，其次为碲铋矿、硫铜铋矿、辉铋铅矿等；铋矿物作为主要载金矿物．与自然金紧密共生；包村矿区Bi-Au相关系数为0．69，铋矿物与金矿化关系非常密切。成矿流体相分离引起的热液硫逸度fs2降低，可能是黑铋金矿分解成金和铋，并最终导致金与铋矿物密切共生的主要原因。

| Abstract: | Located in the Shizishan orefield, Both Baocun and Chaoshan gold deposits are of the skarn type. Bismuth minerals and their relationship with gold mineralization are studied by means of reflect light microscope and electron probe microscope.The results show that bismuth, bismuthinite are main bismuth minerals in the two mines. As main minerals holding native gold, bismuth minerals are closely coexisting with native gold. The correlation coefficient of Bi and Au is (0.69) in Baocun deposit, which proves the closely paragenetic relationship between bismuth minerals and gold mineralization. The falling of fs_2, due to the phase separation of ore-forming fluid, may cause the maldonite to be separated into gold and bismuth. |
