摘　　要：岗讲—白容铜钼矿系斑岩型矿床,位于冈底斯斑岩铜矿带的东段,矿区的含矿斑岩体显示多期次复式岩体特征,铜钼矿化与钾硅化蚀变关系密切。断裂构造对含矿岩体具明显破坏作用,对矿床的剥蚀程度也有明显的影响,研究认为岗讲矿区的剥蚀程度比白容矿区更浅,其"环状"矿体中心的流纹-英安斑岩之下尚有较大的找矿潜力。Gangjiang-Bairong ore deposit is a porphyry Cu-Mo deposit in east Gangdise porphyry Cu ore belt. The ore-bearing porphyry body is characterized by multi-staged intrusion. Cu-Mo mineralization is closely related to K-feldspariztion＋silicification. It is clearly that the ore-bearing porphyry body is con-trolled and destructed by fault and faulting influenced erosion of the deposit apparently. Study on the de-posit shows that erosion depth at Gangjiang mining area is shallower than at Bairong mining area and it is potential in rhyolite-dacite unit under the ring center of Gangjiang ore body.
