2.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.
摘要从研究激电场频谱特征及充、放电时间特征出发，根据实验观测结果，总结了硫化物矿化体（黄铜矿）及含石墨白云质大理岩等岩性的频谱特征及充放电时间特征，探索到新的定性评价激电异常源参数－频率谱及时间谱、视衰减速度。收藏指正
