摘　　要：绿石岗—红石岗矿段位于锡铁山块状硫化物多金属矿带的东南部,区内地质特征与锡铁山铅锌多金属矿段类似。总结了区内矿床地质特征及岩矿石电性特征,在绿石岗—红石岗矿段应用可控源音频大地电磁测深法和瞬变电磁法开展深部找矿工作,划分了含矿地层,圈定找矿靶区4处。应用成果表明,可控源音频大地电磁测深法与瞬变电磁法相结合进行深部找矿,效果较好。Lvshigang-Hongshigang ore section is located in the southeast of Xitieshan sulfide polymetallic ore belt. The characteristics in this area are similar to Xitieshan lead-zinc polymetallic ore section. The paper summarized the geological characteristics of the deposits and the electrical characteristics of rocks and ores in the area,applied CSAMT and TEM for deep ore-prospecting in Lvshigang-Hongshigang ore section,and divided ore-hosting strata.Through that,4 prospecting targets were delineated. The application results show that CSAMT and TEM combined have performed well in deep ore prospecting.
