摘　　要：随着我国表层矿产资源逐渐枯竭,地表找矿越来越困难,未来寻找矿产资源的方向是深部探矿。电磁法作为地球物理勘查的一种有效方法,有其自身的优点,如探测效率高、设备携带方便、成本低、成功率较高等,在近年来地质勘探中发挥了重要作用。2014年以来,地质勘查人员在汝阳县靳村乡北部的矿区采用音频大地电磁与大功率激电联合方法找矿,成果显著,为找矿指明了方向。With the gradual depletion of surface mineral resources in China,surface prospecting is becoming more and more difficult,the future direction of finding mineral resources is deep prospecting.As an effective method for geophysical exploration,electromagnetic method has its own advantages,such as high detection efficiency,easy portability of equipment,low cost,and high success rate,which has played an important role in geological exploration in recent years.Since 2014,geological prospectors have used the combined method of audio-frequency magnetotelluric and high-power induced polarization to prospect for ore in the mining area in the northern part of Jincun Township,Ruyang County,the results are remarkable,pointing out the direction for prospecting.
