| 中文摘要: |
| 音频大地电磁测深（AMT）和大地电磁测深（MT）的采集频段有所不同，探测的深度和分辨率也存在差异：AMT采集频段较高，探测深度小，分辨率高；MT采集频段低，探测深度大，分辨率低。在现阶段的深部资源勘探中，单独地使用AMT或者MT已很难达到目的，急需将二者的优点结合起来，兼顾浅部和深部的信息，提高纵向分辨率，为深部勘探提供更多的物探信息。鉴于此，基于MATLAB脚本语言编程实现了同点位AMT和MT数据的拼接，并对拼接后的数据进行二维反演，兼顾浅部分辨率和探测深度，在泸沽湖地区地热资源勘探中取得了良好的应用效果。 |
| 英文摘要: |
| Data collection frequency-band of AMT is high with small detection depth and high resolution. Data collection frequency-band of MT is low with big detection depth and low resolution. Deep resources exploration at present needs combination of advantages of the two techniques to improve vertical resolution and provide more geophysical information at both shallow and deep locations. With this motivation the authors merge AMT and MT data collected at the same station with MATLAB script programming to build 2 dimensional model by inverting the merged data. The data-merging method is applied to exploration of geothermal resource in the Lugu lake area with ideal result. |
