摘　　要：马关县南当床锌锡多金属矿具有多派、多阶段、多成矿特点,属沉积—变质—岩浆期后热液改造矿床;矿床成因分为三个阶段即:沉积矿源层阶段、区域变质热液迁移聚集阶段和岩浆期后热液叠加富集成矿阶段。围绕花岗岩接触带及剥离断层带,是寻找锌、锡多金属矿(体)的有利于地段。Nandang Zn-Sn multimetallic deposit is characterized by the multi-derivation, multi-stage and multi-metallogenesis,belonging to the sedimentary-metamorphic-postmagmatic hydrothermal reformation deposit.The genesis can be divided into 3 stages： sedimentary ore source bed stage,regional metamorphism hydrothermal migration concentration stage and postmagmatic hydrothermal superimposition concentration metallogenesis stage.The area around the granite contact and desquamation fault zone is the advantageous place to prospecting of Zn-Sn multimetallic deposit.
