摘要
大峪沟金矿位于华熊台隆的外方山断隆区内,岩浆活动强烈,断裂构造发育。矿体均受蚀变破碎带控制,赋存于蚀变构造岩之中,产状基本与含矿构造蚀变带产状一致。矿石中金属矿物主要为金属硫化物及其氧化矿物,成矿物质部分来源于深部火山熔浆和基底矿源层,断裂构造是该区最基本也是最重要的找矿标志。
Dayugou gold deposit is located at Waifangshan fault rift in Huaxiong upwarp, where magmatic activity is intense and fault structures develop. The gold orebody is controlled by altered faulting belt. The altered rock is the host ore--bearing rock. The ore shape is similar to the ore--bearing altered belt. The metal minerals are mainly sulfide and their oxidation minerals. The ore material is partly derived from deep volcanic magma and ore--hosted base strata. The faulting structure is the basic and important prospecting sign.
