摘　　要：南平村地区位于老挝北部长山成矿带,区内断裂构造发育。通过地质测量及地球化学测量工作,在研究区共圈出3个综合异常段及4条铅锌矿化蚀变带。钻孔验证,见到了一层铜钨矿。通过系统分析地质构造特征、综合异常特征及矿化蚀变信息,认为研究区的综合异常与断裂构造、热液活动关系密切,碎裂状绢英岩化花岗岩脉的内外接触带是寻找多金属矿的有利地段。The Nanping Village area is located in the Long Hills metallogenic belt in northern Laos,where fault structures are well developed.By means of geological and geochemical surveys,a total of 3 comprehensive anomaly areas and 4 leadzinc mineralized alteration zones have been delineated in the study area.A layer of copper-tungsten ore was found in the borehole.Based on the systematic analysis of geological structure features,comprehensive anomaly features and mineralized alteration information,it is suggested that the comprehensive anomaly in the study area is closely related to fault structure and hydrothermal activity.The internal and external contact zones of the cataclastic sericitization granite veins are favorable for the exploration of polymetallic deposits.
