摘　　要：多依弄巴铅锌矿床产于中上泥盆统松宗组碳酸盐岩地层中,受北西西向断裂破碎带控制。矿石矿物主要为方铅矿、闪锌矿、水锌矿。蚀变类型为白云石化、硅化、大理岩化和重晶石化。构造、地层岩性、重砂和化探异常是重要的找矿标志。The Duoyinongba Pb-Zn deposit is confined to carbonate rock of the Middle and Upper Devonian Songzong Formation and controlled by NWW-trending fracture zone. Ore minerals are galena, sphalerite and idrozinkite. Wallrock alterations are dolomitization, silicification, marbleization and baritization. Stratigraphic horizon, lithological character, heavy mineral anomaly and geochemical anomaly may be used as prospecting criteria.
