摘要
东昆仑中带 ,发现和查明和金矿有蚀变构造岩型、隐爆角砾岩型、矽卡岩型和石英脉型 4种矿化类型 ,其中前两者为金的主要成矿类型。研究表明 ,构造和岩浆作用是该区金矿成矿两个最主要的成矿条件。成矿显示与以闪长玢岩为代表的印支期浅成 超浅成岩浆岩密切相关 ,且金矿床及闪长玢岩等浅成 超浅成岩均受NW向剪切带的脆性复活构造控制而产出。金的成矿具深源。
The gold deposits, having been found in the middle belt of east Kunlun mountain, are the cryptoexplosive breccia, skarn, altered rock and quartz vein. The study shows that the metallizing in this region are controlled by the tectonization and the magmatism. The oreformation act in close coordination wifh the hypabyssal rock or dioriticporphyrite during the IndoChinese period, And the deposits are controlled by brittle faults within NWSE shear zones. The gold deposits in this area have a obvous characteristics that the oreforming elements coming from deep mineralize in the shallow depth under the middle temperature. [
