| 摘 要： | 在浙江省江山市高塘矿区多金属矿勘查中,应用激电法验证在地形条件复杂,地表植被和残积层覆盖较厚地区探查隐伏矿层的可行性。根据地质任务,在矿区北东布置了4条测线,其中4线、5线采用对称四极激电测深,以发现矿体在垂向（断面）上引起的异常;6-1线、6线采用对称四极激电剖面测量,以了解矿体在平面上的异常范围。通过对ρs、ηs断面等值线图与平面等值线图的解释,圈定了Ⅰ、Ⅱ、Ⅲ号有价值成矿靶区,经后期钻孔验证,成功在Ⅱ号区域钻到四层充填于角砾间的团块状铜矿,证明运用激电方法找矿的可行性。

| Abstract: | During the polymetallic deposit exploration in the Gaotang mine area,Jiangshan City,Zhejiang Province,using the induced polarization method identified the feasibility of hidden ore deposit prospecting in complicated terrain covered with thick surface vegetation and eluvium. According to the geological tasks,4 prospecting lines have been deployed in the northeast part of the mine area. In which,line Nos.4 and 5 have used symmetric quadrupole induced polarization sounding to find out ore body anomalies on vertical sections; line Nos.6-1 and 6 have used symmetric quadrupole induced polarization horizontal profiling to find out ore body anomalous range on plane. Through interpretation of ρs,ηsprofile isogram and plane isogram,delineated I,II and III three valuable metallogenic target areas. After subsequent drilling validation,successfully intersected four layers of lumpy copper filled in breccia in the area II,thus proved the feasibility of induced polarization method in prospecting. |
