CSAMT在隐伏地质构造勘查中的三维可视化应用

在利用地球物理手段勘查隐伏构造的实践中，CSAMT（可控源音频大地电磁测深法）以其横向分辨能力强，探测深度大，受地形影响小等优势而广泛选用。为了直观展示隐伏构造的特征及空间联系，方便和已知地质图件的叠加对比，在资料处理解释过程中，引用了三维可视化处理新方法，使CSAMT探测隐伏地质构造的分辨效果更加清晰，利于解决与隐伏地质构造相关的其他地质问题。

Application of Threedimensional Visualization of CSAMT in Exploring Concealed Geological Structures

In the practice of explorIng concealed structures by using geophysical method, CSAMT (Controlled Source Audio Frequency Magneto Telluric) has been widely used because of its advantages of strong lateral resolving power, deep detecting depths and small influence by terrains. In order to intuitively demonstrate the features and spatial association of concealed structures, and conveniently conduct the superposition comparison with the known geological maps, in the process of data processing and interpretation, the new threedimensional visualization processing method has been used. This method can not only make the resolving effect of the CSAMT detection of concealed geological structures more clear, but also solve other geological problems associated with concealed geological structures.
