摘　　要：燕子沟金矿床位于四川甘孜州丹巴县,永西穹隆核部。矿体主要呈透镜状、似层状赋存于泥盆系危关群浅变质黑色岩系中。矿体的形成与含金石英粗脉和细石英网脉有关,且受断裂控制明显。NNW向牦牛河断裂和EW向磨子沟断裂以及与之相配套的小断裂共同构成的"米"字型构造为成矿流体提供了良好的运移和储存空间。另外,岩浆、变质作用也对成矿起了重要的控矿作用。Yanzigou gold deposit is located in the middle of Yongxi fomix, in danba county, Sichuan province. The ore body occurs in epimetamorphic black shale series in Devonian Weiguan group,is lenticular and stratiform-like. The formation of ore body is related to gold-bearing stockwork quartz veins, and it is obviously controlled by fracture. The ＂X＂ type structure constituted by NNE striking Maoniuhe fault and EW striking Mozigou fault and other small faults provides great migration and storage space for the ore-forming fluid. In addition, magmatism and metamorphism play very important rules in mineralization.
