摘要
可控源音频大地电磁测深法是深部找矿的有效地球物理手段之一,该文以山东省蒙阴县西峪矿区为例,探讨了可控源音频大地电磁测深法在金刚石原生矿找矿中的应用,并对测线反演电阻率断面图上的低阻异常进行解译,金伯利岩在断面图上多为低阻与高阻之间的梯度带,其解译结果与钻探验证结果相吻合,进一步证明该方法在金刚石原生矿找矿是行之有效的手段。
Controlled source audio magnetotelluric method is one of the effective geophysical methods for prospecting ores in deep part.Taking Xiyu mining area as an example,the application of controlled source Audio magnetotelluric method in prospecting diamond primary ores have been studied,and the low resistance abnormality on the line inversion section of resistivity profile has been interpretated.Kimberlite in the section map is mostly the gradient zone between low resistance and high resistance.The interpretation results are consistent with the results verified by the drilling.It is proved that this method is effective for prospecting diamond primary ores.
