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。实践证明,利用频率谱定性评价硫化物矿化体(黄铜矿)与含石墨白云质大理岩激电异常源取得较佳效果。
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.
