摘　　要：云南者桑金矿位于我国滇黔桂“金三角”地区,区内矿体按围岩岩性可分为辉绿岩型、碎屑岩型(泥质板岩或粉砂岩型)、泥灰岩型,本文通过三类矿体矿石进行系统的岩相学和地球化学研究,对不同类型矿体的成因进行探讨,得出者桑金矿辉绿岩型矿体成矿温度为中–低温,碎屑岩型矿体为低温型,泥灰岩型矿体为中–低温型;矿区三种类型矿体成因均为卡林型,碎屑岩型(泥质板岩或粉砂岩)矿体成因还可能受岩浆热液影响,泥灰岩型矿体成因可能受岩浆热液和变质热液影响,对矿区找矿起到一定的参考作用。Zhesang Gold Mine in Yunnan is located in the “Golden Triangle” area of Yunnan, Guizhou and Guangxi, China. According to the surrounding rock lithology, the ore bodies in this area can be divided into diabase type, clastic rock type (argillaceous slate or siltstone type) and marl type. Based on the systematic petrographic and geochemical study of the three types of ore bodies, the genesis of different types of ore bodies is discussed, and it is concluded that the mineralization temperature of the diabase type ore body in Zhesang Gold Mine is medium-low temperature, the clastic rock type ore body is low temperature and the marl type ore body is medium. The genesis of the three types of ore bodies in the mining area are all Carlin type, the genesis of clastic rock type (argillaceous slate or siltstone) ore bodies may also be influenced by magmatic-hydrothermal solution, and the genesis of marl type ore bodies may be influenced by magmatic-hydrothermal solution and metamorphic hydrothermal solution, which plays a certain reference role in prospecting in the mining area.
