大功率激电在赣东北某黑滑石矿勘查中的应用

The application of high power IP in the exploration of a black talc mine in Northeast Jiangxi

根据滑石矿与围岩的电性差异投入大功率激电,采用中梯测量装置,利用激电中梯异常推断滑石矿(化)体的赋存空间及延伸情况,根据激电中梯剖面异常曲线拐点位置判断滑石矿(化)体的边界,经钻探验证,效果较好。

According to the electrical difference between talc and surrounding rock,high-power IP is put into operation.Using the middle ladder measuring device,the occurrence space and extension of talc(mineralized)body are inferred by using the middle ladder anomaly of IP,and the boundary of talc(mineralized)body is judged according to the inflection point position of the abnormal curve of middle ladder profile of IP.The effect is good after drilling verification.
