Abstract: Combined profiling method and direct current electric sounding method have the character of relative obvious abnormal electrical and high resolution in prospecting stratum and lithology electrical changes,tracking the tectonic research area etc.Applicaton result indicates that these two methods could do better in distinguishing containing mineral rock stratum based on limestone,siliceous rocks containing rich mineral have a high resistivity and low polarity.The engineering examples prove the feasibility synthesize combined profiling method and direct current electric sounding method in containing mineral stratum exploration.
