摘　　要：探讨频率域激电法在西南山区多金属矿调查中的应用效果。通过综合分析前期的地质、物探、化探、遥感等信息圈定找矿重点区,在充分研究重点区的地质条件、地球物理特征的前提下,选用了双频激电的中梯装置对重点区进行探测,结果表明多个重点区的多种金属矿的激电异常非常明显,根据视幅频率异常等值线平面图准确圈定了矿化区域。并且以其中一个重点区的探测结果为例进行详细说明。This paper discusses the application of frequency-domain IP method in several polymetallic ore deposits in the southwest areas of China. Based on the integration analysis of the information obtained by geology, geophysical and chemistry exploration and remote sensing, the main prospecting area is outlined. And the middle-gradient configuration of dual-frequency IP method is chosen to use in these area. The result shows that many polymetallic ore deposits have obviously different IP characteristics. Using this result, mineralization areas have been confirmed. This paper instructs the application result of IP method taking one main prospecting area for example.
