摘　　要：上湾地区位于安徽省石台县东北部,在长江中下游铜-铁-金成矿带与皖南钨-钼-锡成矿带之间的江南过渡带上,具有较大的找矿潜力。本研究通过大比例尺地质、物化探测量、地表工程揭露和深部钻探验证,初步查明区内地质及物化特征,圈定多处综合异常区,发现多条银、铅、锌等多金属矿(化)体,分析总结研究区内铅锌银多金属矿(化)的成矿规律及成矿要素,认为其成因类型为中低温热液型铅锌银多金属矿。本文归纳了研究区内铅锌银多金属矿的成矿要素,可作为本区铅锌银多金属矿找矿预测的参照模型。The Shangwan area is lo cated in the northeastern of Shitai County,Anhui Province,on the Jiangnan transition zone between the copper-iron-gold metallogenic belt in the middle and lower reaches of the Yangtze River and the tungsten-molybdenum-tin metallogenic belt in the south of Anhui Province,and it has a great mineral exploration potential.Through large-scale geological,geophysical and geochemical prospecting,surface engineering exposure and deep drilling verification,this study has preliminarily identified the geological and geophysical and geochemical characteristics of the area,delineated multiple comprehensive anomalies,and discovered multiple polymetallic ore(mineralization)bodies including silver,lead and zinc.Analyzing and summarizing the metallogeny and metallogenic elements of the lead-zinc-silver polymetallic ores(mineralization)in the study area,it is concluded that the genesis type is a medium-low temperature hydrothermal type lead-zinc-silver polymetallic deposit.The paper summarizes the metallogenic elements of the lead-zinc-silver polymetallic deposits in the study area,which can serve as a reference for the prediction of lead-zinc-silver polymetallic deposits prospecting in this area.
