摘　　要：武当地区地形复杂、覆盖厚,银金矿找矿难度大,本次研究首次在该区引入双频激电地球物理勘查方法。测量数据显示研究区银金矿石与围岩视幅频率F s值具有明显差异,矿石的视幅频率F s一般都在3.1%以上,而非矿岩石的视幅频率一般较小;含矿层位与金属硫化物分布范围基本一致,研究区具有开展双频激电法找矿的前提;使用双频激电法在研究区内划分了11处异常体,其中J3和J8两处异常经查证具有良好的银金矿找矿潜力。双频激电法在该区的成功使用为武当地区寻找构造热液银金矿床提供了新的思路。The Wudang area is difficult to find silver gold deposits because of complex terrain and thick coveraget.In this study,a dual-frequency IP geophysical exploration method is introduced in this area for the first time.The measured data show that there is a significant difference in the F s value of the silver-gold ore and surrounding rocks.The orbital frequency F s of the ore is generally above 3.1%,and the apparent amplitude of the non-mineral rock is generally smal.The distribution between the ore-bearing stratum and the metal sulfides is basically the same.The study area has the premise of conducting dual-frequency IP method.There are 11 anomalies in the study area by using the dual-frequency IP method.J3 and J8 anomalies own the silver gold ore prospecting potential.The successful use of the dual-frequency IP method in the area provides a new idea for prospecting in the Wudang area.The successful use of dual-frequency IP method in this area provides a new idea for the exploration of tectonic hydrothermal silver and gold deposits in Wudang area.
