在实验室对人工合成的岩、矿石标本进行了复电阻率特性测量,利用标本的复电阻率振幅频谱曲线反演求得其Cole—Cole模型参数,讨论了各标本的Cole—Cole模型参数的异同,得出了可以通过标本的4个模型参数(ρ0、m、τ、C)区分良导电、高极化率岩、矿石,达到区分矿与非矿的目的的结论,为在有干扰地层(黄铁矿、炭质层等)的地区开展物探电法找矿工作提供了试验依据。
在實驗室對人工閤成的巖、礦石標本進行瞭複電阻率特性測量,利用標本的複電阻率振幅頻譜麯線反縯求得其Cole—Cole模型參數,討論瞭各標本的Cole—Cole模型參數的異同,得齣瞭可以通過標本的4箇模型參數(ρ0、m、τ、C)區分良導電、高極化率巖、礦石,達到區分礦與非礦的目的的結論,為在有榦擾地層(黃鐵礦、炭質層等)的地區開展物探電法找礦工作提供瞭試驗依據。
