人工合成岩矿石频谱参数对比及其找矿意义研究

Research of Synthetic Rocks Spectrum Parameters Contrast and its Prospecting Significance

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。

Synthetic rocks and ore samples＇ complex resistivity were measured in this experiment,used Cole-Cole model to fit the complex resistivity spectrum curve follow the system theory, obtained four Cole-Cole model parameters,discussed the similarities and differences of Cole-Cole model parameters between various samples,obtained the conclusion that can distinguish good conductivity and high susceptibility rock or ore by the four model parameters （ρ0、m、τ、C） and distinguish mine and non-mine, provide the experimental basis that can carry out geophysical electrical prospecting in interference formation （pyrite, carbonaceous layer, etc.） areas.
