Starting with the research on the characteristics of frequency spectra of the IP field as well as charging-discharging time and based on experiment results,the authors summed up frequency spectra,time spectra and decay rate characteristics of sulfide mineralized bodies(chalcopyrite) and graphite-bearing dolomitic marble,and detected new parameters for qualitative evaluation of IP anomalies.Practice shows that the application of frequency spectrum characteristics to the evaluation of IP anomalies caused by sulfide mineralized bodies(chalcopyrite) and graphite-bearing dolomitic marble is effective.
