摘　　要：滇西仁和铅锌铁多金属矿,矿体呈脉状、似层状赋存于上寒武统沙河厂组二段大理岩与板岩的层间破碎带中.矿区近矿围岩蚀变发育,主要有大理岩化、硅化、绿泥石化、绿帘石化、矽卡岩化及黄铁矿化,成矿元素由浅部至深部具有明显的分带特征.矿床受地层、构造和深部中酸性隐伏岩体控制,成因类型为沉积改造-矽卡岩型铅锌铁多金属矿床.The orebody of Renhe Pb-Zn-Fe multimetallic depoit in W Yunnan is veined,stratoid in the interbed fracture zone of Upper Cambrian Shahechang Formation Member 2 marble and slate.The wallrock alteration near orebody developed,mainly marblization,silicification,chloritization,epidotization,skarnization and pyritization.The metallogenesis elements are in clear zonation from the shallow to the deep.The deposit is controlled by the strata,structure and intermediate-acid buried rockbody in the deep.It belongs to the sedimentary reformed skarnization type Pb-Zn-Fe multimetallic deposit in genesis.
