摘　　要：激发极化法是寻找硫化物金属矿床的一种有效方法,被广泛应用于矿产勘查中.在内蒙古阿荣旗矿产远景调查中,运用时间域激发极化法,通过激电中梯扫面测量后,绘制视电阻率与视极化率等值线平面图,迅速地圈定激电异常.依据地质与化探调查结果,选择其中3个激电异常区做激电测深.通过对激电测深数据反演,得到极化率与电阻率断面图,确定了潜在矿(化)体的形态.Induced polarization （IP） is an effective method widely applied in mineral exploration for sulfide deposits. The method of time domain induced polarization is adopted in the prospective mineral survey in Arun Qi, Inner Mongolia. After IP measurement in gradient array, the apparent chargeability and apparent resistivity contour maps are plotted, then the high chargeability anomalous areas are discovered quickly. Based on geological and geochemical survey results, three anomalous areas are selected for vertical IP sounding. By inversion of the vertical IP sounding data, the chargeability and resistivity sections are obtained. The positions of potential ore （mineralization） bodies are delineated.
