摘　　要：近几年来在广西大瑶山西侧做了大量的物探工作,主要应用大功率激电和可控源音频大地电磁测深方法(CSAMT)进行找矿,取得了很好的找矿效果。在广西武宣六峰山矿区隐伏铅锌矿勘查中,将大功率激电法用于快速发现和圈定矿区矿化范围及构造展布情况,用CSAMT法反演电阻率断面图推测地下岩性电性特征、构造产状及矿(化)体的赋存空间,为钻探工程提供依据。Recent years,a large number of geophysical prospecting work has been done on the west side of Dayaoshan,Guangxi,mainly using high power IP and controlled source audio magnetotelluric sounding（CSAMT）for prospecting,and good prospecting results have been obtained.In the exploration of hidden lead-zinc mine in Liufengshan mining area in Wuxuan,Guangxi,the high power IP method is used to quickly discover and delineate the mineralized range and structure distribution.The resistivity section which retrieved by CSAMT method use to speculate the electrical characteristics of the underground lithology,the structure and the deposit space of the ore（chemical）body,and provides the basis for the drilling engineering.
