摘　　要：西蒿坪地区位于扬子陆块北缘,为湖北省重要的铅锌矿产地之一。笔者在野外调查基础上,总结了该地区典型铅锌矿床--吴家山铅锌矿的地质及矿化特征,分析了区内铅锌矿床的控矿因素并提出了下一步找矿方向。吴家山铅锌矿床的矿体主要呈层状、似层状,分上、下两层沿震旦系灯影组层间断裂产出,矿石以脉状、团块状、星点状构造为主,金属矿物主要有方铅矿、闪锌矿、黄铁矿、赤铁矿、黄铜矿等,蚀变主要有硅化、白云石化、方解石化、重晶石化等。西蒿坪地区铅锌矿的控矿因素主要为地层及断裂,其中震旦系灯影组为该类矿床的主要赋矿层位,沉积断裂及层间断裂为铅锌富集与就位提供有利空间。结合该地区成矿地质条件及地球化学找矿信息,梭子河-青岗一带具有良好的铅锌矿产找矿前景。The Xihaoping area is located on the northern edge of the Yangtze block and is one of the important lead-zinc mineral deposits in Hubei province.Based on field investigations,the authors summarized the geological and mineralization characteristics of the typical lead-zinc deposit in the area-Wujiashan lead-zinc deposit,analyzed the controlling factors of lead-zinc deposits in the area,and proposed the next direction for prospecting.The ore body of the Wujiashan lead-zinc deposit is mainly layered and quasi layered,divided into upper and lower layers and produced along the interlayer faults of the Dengying formation of Sinian system.The ore is mainly characterized by vein like,block like,and star like structures.The metallic minerals mainly include galena,sphalerite,pyrite,hematite,chalcopyrite,etc.The weathering mainly includes silicification,dolomitization,calcite,and barite.The controlling factors of lead-zinc deposits in Xihaoping area are mainly stratigraphy and faults,among which the Dengying formation of Sinian system is the main ore-bearing layer of this type of deposit,and synsedimentary faults and interlayer faults provide favorable space for lead-zinc enrichment and positioning.Based on the geological conditions of mineralization and geochemical prospecting information in the area,the Suishuohe-Qinggang area has good prospects for lead-zinc mineral exploration.
