摘　　要：桦树沟铁铜矿床铜矿体呈隐伏、半隐伏状态赋存于铁矿体下部,构成上铁下铜格局。铜矿的形成与海底火山喷气热泉活动关系密切,成矿物质既有正常沉积岩的特征又有火山源的特征,并经变质热液和岩浆热液改造使其进一步富集。Cu ore bodies occur blindly or semi-blindly beneath Fe ore bodies in Huashugou Fe-Cu ore district. The formation of Cu ore body is closely related to marine volcano exchalation and hot springs. Metallogenic material has not only the signatures of sedimentary rock but also volcanic rock, and the metallo-genie material is enriched by the metamorphic and magmatie hydrothermal rework.
