研究区地处云南省保山市施甸县，赋矿层位为二叠系沙子坡组白云岩。地层受构造作用影响较为破碎，仅为该区矿床形成提供了有利的运输和容矿空间。在前人的研究基础上，以东山地区铅锌矿为研究对象，主要的研究内容是区域地质，地质特征，矿体及矿石特征等，通过对硫、碳、氧同位素的分析研究，总结出了该地区铅锌矿物质来源和成矿环境，认为东山铅锌矿施甸县铅锌矿床属于碳酸岩型沉积～热液改造矿床。%The study area is located in Shidian County,Baoshan Yunnan,and the ore hosting ledge is Permian sand slope groups dolomite. The formations affected by tectonics are relatively broken ,which only provide favorable transport and ore-hosting space for the formation of deposits in the area. Based on previous research on lead-zinc mine in Dongshan area,the regional geology,geological features,ore and ore characteristics were studied. Through analysis of sulfur,carbon and oxygen isotopes,we summed up the lead-zinc material sources and mineralization environment in the region. It was considered that Dongshan lead-zinc deposits are carbonate-type sedimentary-hydrothermal deposits.
