摘　　要：克峡希铜矿位于博罗科努金、铜、钼、铅、锌成矿带西侧。矿体赋存于成群产出的辉石闪长岩、闪长岩及花岗闪长岩等小岩体组成的杂岩体中,受NE向密集剪切劈裂带控制。铜矿成矿经历岩浆晚期残余气液矿化和岩浆期后热液成矿二个阶段,早期为细脉浸染斑岩型,沿外接触带发育矽卡岩型,晚期为热液脉型,具有金、铜、钼矿化特征,空间上具有明显分带性,属于复合成因的斑岩型铜矿床,构成了本矿床的斑岩型金、铜、钼矿的成矿系列,预测具有大型矿床的找矿前景。Kexiaxi Cu deposit is located in the west side of Boluokenu Au-Cu-Mo-Pb-Zn metallogenic belt.The orebodies are hosted in the complex body of pyroxene diorite,diorite and granodiorite,which are controlled by the dense shear zone in NE direction.The formation process of Cu deposit has experienced two stages of late-magmatic residual gas-liquid mineralization and post-magmatic hydrothermal mineralization.In the early stage it is fine vein disseminated type,and skarn type along the outer contact zone.In the later stage it is hydrothermal vein type,which has the characteristics of Au-Cu-Mo mineralization with obvious zoning in space.They are belonged to the porphyry Cu deposit of compound genesis.They constitute the porphyry metallogenic Au-Cu-Mo series of the deposit with the forecasting of the prospecting perspective of large-scale deposit in the region.
