摘　　要：在多金属矿预查区内矿体勘查中,受不同地质条件的影响导致勘查难度增加。如果勘查结果偏离实际结果较远,将会浪费大量的人力、物力。为此,利用激电测量装置对某地多金属矿预查区展开地质勘查。在预查区内放置激电测量装置,并将勘查地区划分Ⅰ线和Ⅱ线两条剖面;分析两条剖面的电性特征,并结合激电测量装置解译推断的反演结果,确定该预查区内矿产主要分布在板岩、大理岩相接部位以及板岩深部极化率的异常部位和低阻高极化的异常特征。经研究证明,将激电测量用于多金属矿预查区地质勘查中,取得了良好的正演拟合效果,测量精度高,具有较高的应用价值。In the exploration of ore bodies in the polymetallic ore pre-survey area,the difficulty of exploration in⁃creases due to the influence of different geological conditions.If the exploration results deviate significantly from the actual results,it will waste a lot of manpower and material resources.To this end,the IP measurement device was used to carry out geological exploration in the pre-survey area of polymetallic ore in a certain place.An IP measure⁃ment device was placed in the pre-survey area,and the survey area was divided into two sections,line I and line II.The electrical characteristics of the two sections were analyzed,and combined with the inversion results of the inter⁃pretation and inference of the induced polarization(IP)measurement device,it was determined that the minerals in the pre-survey area were mainly distributed in the junction of slate and marble,as well as the anomaly of deep polar⁃izability of slate and the anomalous characteristics of low resistance and high polarization.Through research,it had been proven that the use of induced polarization measurement in geological exploration of polymetallic ore pre explo⁃ration areas had achieved good forward fitting results,high measurement accuracy,and high application value.
