摘　　要：康西铅锌矿位于塔里木盆地西北缘,乌拉根大型铅锌矿的西侧,属于层控砂砾岩型铅锌矿床。康西铅锌矿产于库什维克复式向斜的北翼,矿体呈层状、似层状赋存于下白垩统克孜勒苏群第五岩性段(K1kz5)灰白色砂砾岩和古新统阿尔塔什组(E1a)底部的坍塌角砾灰岩中。地表控制铅锌矿化蚀变带长约7.0 km,矿化集中区段长约5.0 km。深部钻探验证显示,不仅赋矿层位向深部稳定延伸,而且矿化有加富、加厚的特点。具有形成大型铅锌矿的成矿潜力。The Kangxi Pb - Zn deposit is located in the northwestern Tarim basin and the western side of the large sized Wulagen Pb -Zn deposit. It is a strata- bound conglomerate type lead -zinc deposit, there are same ore -bearing layers, rock association and ore - forming geological characteristics as the Wulagen Pb - Zn deposit occurred in the north limb of Kushiweike anticline. The ore bodies occur as layers or layer- like shapes in the fifth member of white -grey sandy conglomerates （Klkz5） of Cretaceous Kezilesu group and brecciaed limestone of Paleocene Aertashi formation （Ela）. The mineralized alteration belt is about 7 km long in the surface and the concentrated mineralized belt is about 5 km long. The test deep drilling results show that the ore - bearing layers extend steadily to the depth and the mineralization zone tend to more thick and high grade. There ispotential to form a large sized lead -zinc deposit.
