摘　　要：对贵州省丹寨县老东寨铅锌矿床地质特征、含矿地层以及构造进行分析,矿体主要赋存于陡山沱组一段碳酸盐岩地层中,层控特征明显。矿体主要受矿区北东向F21断层破碎带控制,产状与破碎带产状基本一致,该断层为含矿热液导矿构造,同时也是容矿构造。有益组分以Pb、Zn为主,并伴生有Ag、Ge、Ga。矿体厚度变化为较稳定,品位变化均匀,估算铅锌金属资源量逾40万吨,达中型矿床规模,为该区域震旦系陡山沱组地层中首次发现的单矿体规模达中型的矿床规模。By analysis geologic characteristics,strata and structure of Danzhai Laodongzhai Pb-Zn deposit,the ore bodies are occur in carbonate rock which located in the 1 st of the Sinian Doushantuo formation and the stratabound feature is obvious.The ore bodies are limited to the fault F21 that stretch to N-E,this fault is not only the leading structure of ore-bearing geotherm but also ore-hosting structure.Pb-Zn sulfides are main ore minerals associated with Ag、Ge、Ga.It is preliminarily evaluated more than 400000 tons Pb-Zn polymetallic resources,for the first time,the size of single ore was found to reach a midium-sized deposit.
