摘　　要：铅锌矿赋存于上三叠统三合洞组下段(T3s1)灰岩容矿岩层中及近南北向、北北东向、北西向断裂破碎带内,少数赋存在近东西向节理裂隙中,成因具多成矿阶段、多成矿物质来源特征,层位+构造控制的中低温热液型铅锌多金属矿床。The Pb - Zn deposit is in the ore - bearing limestone of Upper Triassic Sanhedong Formation Lower Member （T3s1 ） and nearly NS, NNE, NW fault fault fracture zone. A few are in the nearly EW joint fissure. It is a Pb - Zn multimetallic deposit of middle - low T hydrothermal type in genesis, which is controlled by horizon and structure with multiple metallogenetic stage and material source.
