摘　　要：双频激电法可同时得到低频和高频电位差,由其计算视幅频率可抵消相同的影响因素,抑制干扰,增强异常幅值,提高观测精度。在分析区域成矿背景、矿区成矿地质特征、矿床地质特征的基础上,结合双频激电法的成果解译结果,对区内铜矿体成矿的有利区段进行了预测,优选出两个找矿靶区,为该区边深部找矿指明了方向。The dual frequency induced polarization method can get both low and high frequency voltages simultaneously. Its apparent amplitude frequency calculations can eliminate identical influencing factors, suppress noises, enhance anomaly amplitudes and improve accuracy of observations. This paper, based on the study of the regional geological setting, mineralization characteristics of ore field and geological features, and combining the results of the dual frequency induced polarization method on abnormal area measurement, predic- ted copper ore body mineralization favorable section, optimized two prospecting targets, and pointed out the direction for the mine to find ores in the depth and outer regions.
