音频大地电磁法在黄土区填图中的应用

Application of Audio Magnetotelluric Method in Loess Area

  • 摘要: 通过在工作区内布设音频大地电磁测线,并结合当地已有的地质与测井资料对测深数据进行约束反演,结果表明:①音频大地电磁测深法对工作区的地层岩性分层具有较好的效果,并对深部的基岩面与上部土层的分界具有较好的反映;②工作区内的地层产状比较稳定;③测点点距对结果精准度有一定的影响。进一步总结了音频大地电磁法在黄土区填图中的适用性,对指导音频大地电磁法在黄土区填图中应用具有重要意义。

     

    Abstract: By setting up audio frequency magnetotelluric survey line in the working area, and combining with the existing geological and logging data, the constrained inversion is carried out on the sounding data. The results show that: ① audio magnetotelluric method has a good effect on the stratigraphic and lithologic stratification of the working area, and has a good reflection on the boundary between the deep bedrock surface and the upper soil layer; ② in the working area, the attitude of the formation is relatively stable; ③ the distance between survey points has a certain impact on the accuracy of the results. Furthermore, the applicability of audio magnetotelluric method in Loess geological mapping is summarized, which is of great significance to guide the application of audio magnetotelluric method in Loess geological mapping
