摘　　要：云南保山市陡崖铁铜多金属矿位于保山-镇康铅锌多金属矿带北段,矿区内的铅锌矿体赋存于灰岩构造裂隙或破碎带中;磁铁矿体、铜矿体产于矽卡岩中;钨矿体产于矽卡岩及矽卡岩破碎带中。整个矿床属于与构造-岩浆热液有关的热液-矽卡岩型矿床。从矿区较好的物化探异常看,在矿区深部寒武系上统沙河厂组一段(∈3■h1)中寻找“层控”矽卡岩型多金属矿,有很好的找矿前景。Douya Fe-Cu multimetallic deposit in Baoshan,Yunnan is in the N section of Baoshan-Zhenkang Pb-Zn multimetallic metallogenesis zone.The Pb-Zn orebody is in the structural fissure and fracture zone of limestone.The magnetite and Cu orebodies are in the skarn.The W orebody is in the skarn and skarn fracture zone.The whole deposit belongs to the hydrothermal skarn deposit related to the structure-magmatic heat fluid.According to the good geophysical-geochemical anomaly in the orefield,there is the good prospecting potentiality of“stratabound”skarn multimetallic deposit in the underground Upper Cambrian Shahechang Formation Member 1(∈3sh1)of the orefield.
