摘　　要：处于长江中下游成矿带中段、庐枞盆地北缘、清水塘—岳山铁、铅锌找矿靶区的西湾铁多金属矿预查区地势低洼,水网密布,地表覆盖厚。为了解决在覆盖区找铁多金属矿的难题,采用地质与综合物探相结合的方法,通过对重、磁、电异常的分析,明确了找矿目标,确定了有利的找矿部位,通过钻探验证,在激电异常部位发现了铅锌矿,取得了良好的找矿效果。Located in the middle segment of the Middle and Lower Yangtze metallogenic belt and on the northern margin of Lu-Zong basin,the Xiwan iron-polymetallic ore pre-survey area of the Qingshuitang-Yueshan iron and lead-zinc ore-prospecting target is characterized by low-lying relief,dense network of rivers and thick overburden. In order to solve the problem of prospecting for iron-polymetallic deposits in thick overburden areas,the authors adopted the combined geological and integrated geophysical method to analyze gravity, magnetic and electric anomalies,thus making clear the ore-prospecting target and determining the favorable ore-prospecting position. Drill verification led to the discovery of a lead-zinc deposit at the position of IP anomaly,thus attaining ideal ore-prospecting result.
