印尼中苏拉威西波龙谷金矿地质特征——一种斑岩型金-银、铅、锌多金属矿床

Geological Characters of Polonggu Gold Deposit in Sulawesi,Indonesia

波龙谷金矿床产于新生代火山岩岛弧环境。金矿体主体赋存于石英闪长玢岩岩体和岩墙之内和内、外接触带,矿石构造以细脉状、细粒浸染状为主,蚀变带和矿化带受石英闪长玢岩岩体、岩墙形态和接触带控制。矿床形成与玢岩岩体、岩墙有密不可分的关系,属于斑岩型金-银、铅、锌多金属矿床。

Polonggu gold deposit occurs in volcanic island-arc environment of genozoic,the gold ore body occurs in the rock mass,dyke and the contact zone of quartz diorite porphyrite,the ore structure mainly is vein and impregnation.The alteration zone and mineralization zone are controlled by the rock mass,dyke and the contact zone of quartz diorite porphyrite.The deposit formation has deep relation with the rock mass and the dyke of porphyrite.
