双频激电法在豫西山区快速找矿评价中的应用

Application of dual-frequency induced polarization method in prospecting in Western Henan province

文章主要介绍了双频道激发极化法在河南省豫西山区快速找矿工作中的应用,以及在野外施工过程中应注意的几个问题。通过双频激电中梯测量,在工作区圈定了3处激电异常,结合该区地质资料,岩(矿)石物性特征以及化探次生晕资料对激电异常进行了综合研究分析,经过钻探验证,此异常与隐伏钼矿体和钼矿化有关。证明了双频激电法完全能适应在豫西山区进行快速找矿评价,并取得良好的效果。

In this paper, authors mainly introduce the process of use of dual -frequency induced polarization in the rapid explo- ration of the mountain area of western Henan Province and the issues which should be paid attention in the field survey. Through dual - frequency induced polarization intermediate gradient survey, three induced polarization anomalies from the working area has been dis- covered. In addition, they integratedly analyze the induced polarization anomaly through local geological data, physical properties of rocks and geochemical secondary halo. The drilling has proved that the anomaly had relationship with concealed molybdenum minerali- zation and molybdenum mineralization, which, having achieved good results, proves that dual - band induced polarization is fully adapt to the rapid exploration and gaining evaluation of the mountain area of western Henan Province.
