摘　　要：勐糯铅锌矿床位于保山地块南西部,为一大型铅锌矿床。拟通过研究矿区不同标高、不同平面范围的铅锌矿化富集规律及围岩蚀变分带特征,总结出矿区的成矿地质体、成矿结构面和成矿作用标志,为矿区部署下一步勘查重点工作提供依据。通过总结矿区各探矿工程对矿体的揭露情况,矿区的矿化在平面上呈现一定的分带性,51#勘探线以南,矿化以Zn为主,180#勘探线以北,矿化以Pb为主。矿区内20#—28#勘探线的矿化较为富集,矿石品位高,矿体厚度大,可以推断,矿区为一个以20#—28#勘探线为矿化中心,向南、向北逐渐减弱的矿化系统,与矿化关系较为密切的围岩蚀变为碳酸盐化,硅化次之。Mengnuo lead-zinc deposit is a large-scale lead-zinc deposit located in the south west of Baoshan block.Based on the study of the enrichment law of lead-zinc mineralization in different elevation and plane range and the characteristics of alteration zoning of surrounding rock in the mining area,this paper summarized the ore-forming geological body,ore-forming structural plane and ore-forming indicators of the mining area,and provided the basis for the next exploration work of the mining area.Through summarizing the exposure of ore bodies by various exploration projects in the mining area,the mineralization of the mining area showed certain zoning on the plane.The 51 th exploration line was in the south,mineralization was mainly Zn;however,the 180 th exploration line was in the north,mineralization was mainly Pb.The mineralization of the 20 th-28 th exploration lines in the mining area was relatively rich,the ore grade was high,and the thickness of the ore body was large,which can be inferred the mining area was a mineralization system with the 20 th-28 th exploration lines the mineralization center,and the mineralization gradually weakened in the South and North.The surrounding rock closely related to mineralization changed into carbonation,followed by silicification.
