摘　　要：里伍铜矿床位于扬子地台西缘,是中型铜多金属矿床,其成矿背景复杂,找矿潜力巨大。这里利用ETM+遥感影像,进行研究区的构造解译和矿化蚀变信息提取,并结合区域地质、化探、物探信息进行综合找矿信息分析。分析结果表明:矿区环形构造边缘和线性构造交叉附近遥感异常强烈,里伍铜矿外围的黑牛洞、柏香林、挖金沟、白岩子、笋叶林、上海底为找矿远景区。The Liwu copper deposit is a typical medium-sized polymetallic deposit in the western margin of Yangtze terrane,which has a complex metallogenic setting and is potential for the prospecting.The paper analyses the information of comprehensive exploration from the ETM+ image for structure interpretation and the extraction of alteration information,and the geological,geophysical and geochemical information,and the results show that the margin of the circular structure and the intersection of linear structure have strong remote sensing anomalies,and areas of Heiniudong,Boxianglin,Wajingou,Baiyazi,Sunyelin,Shanghaidi are the potential for prospecting of the copper deposit.
