摘　　要：黔东铅锌成矿带是贵州铅锌矿的重要产区,区内铅锌矿床(点)虽多,但单个矿床规模较小,随着五指山矿田成矿带的归属问题得到解决,打破了该区内无大型矿床的历史,区内铅锌矿床主要沿木黄-贵阳-普安大断裂北西侧和以三都—万山大断裂为中心呈带状展布。经过对比研究,这些矿床的赋矿围岩为震旦系—寒武系碳酸盐岩,矿体受控于NE向的断层-褶皱构造组合,并伴随白云石化和方解石化。成矿时代为早古生代奥陶世,成矿物质来源于基底岩石,是扬子板块和华夏板块碰撞、造山的产物,属于典型的密西西比河谷型(MVT)铅锌矿床。The Pb-Zn mineralization belt in East Guizhou is an important production area of Guizhou.Although there are many lead-zinc deposits(ore points)in the area,the scale of a single deposit is still small.With the determination of the mineralization belt of the Wuzhishan ore field,the history of no large-scale deposits in the area is broken.The Pb-Zn deposits in the area are mainly distributed as a belt along the northwest side of the Muhuang-Guiyang-Puan fault and are centered on the Sandu-Wanshan fault.After comparative studies,the Pb-Zn deposits are hosted in Sinian-Cambrian carbonate rocks.The orebodies are controlled by NE-trending fault-fold structural combination,accompanied by dolomitization and calcitization alteration.The metallogenic epoch is Ordovician in the Early Paleozoic.The ore-forming materials are derived from basement rocks.These Pb-Zn deposits are the product of collision and orogeny between the Yangtze and Cathaysia plates.They belongs to Mississippi Valley-type(MVT)Pb-Zn deposit.
