摘　　要：云南施甸县东山铅锌矿,矿体呈脉状、透镜状位于近南北向之断裂附近,近矿围岩为二叠系沙子坡组(Ps)碎裂状白云岩。该铅锌矿属构造、断层-构造控制的热液型矿床。近南北向构造破碎带重晶石化、方解石化、黄铁矿化均是直接的找矿标志。The orebody of Dongshan Pb-Zn deposit in Shidian,Yunnan is veined,lenticular near NS fault.The wall rock near orebody is P Shazipo Formation(Ps)fractured dolomitite.It is the hydrothermal deposit controlled by fault.The baritization,calcitization,pyritization of NS fault are the direct prospecting criteria.

关 键 词：构造控矿 热液型矿床 找矿标志 云南施甸东山
