摘　　要：云南保山市金厂河铜多金属矿区位于保山-镇康铅锌多金属成矿带北段。区内的铅锌矿、铜矿、磁铁矿均可单独形成隐伏矿体,各矿体呈层状、似层状赋存于上寒武统核桃坪组二段(∈3h2-1)矽卡岩带中。不同矿体空间分布由上具有垂直分带的特征。从本区的重力低异常特征推断地下测深部存有隐伏中酸性岩体,矿床成因属与岩浆热液活动有关的矽卡岩型矿床。Jinchanghe Cu multimetallic orefield is in the N section of Baoshan-Zhenkang Pb-Zn multimetallic metallogenesis zone.In this area,the buried orebodies of Pb-Zn deposit,Cu deposit and Manetite deposit can be formed independently.The orebodies are bedded,stratoid in Upper Cambrian Hetaoping Formation Member 2(∈3h2-1)skarn zone.The different orebody has the vertical zonation feature.According to the low gravity anomaly,we infer that there is the buried intermediate-acid rockbody in the deep part.It is the skarn ore deposit related to the magmatic hydrothermal agent in genesis.
