摘要
介绍了采用可控源音频大地电磁(CSAMT)测深在相山火山盆地邹家山地区进行的深部地质结构探测研究。通过此次探测,成功划分出了该地区2 km以浅范围内的组间界面和基底界面,识别出了3条断裂,揭露了地下岩体、构造的形态特征。通过与钻孔信息对比,发现CSAMT方法所划分的组间界面位置与实际位置吻合较好,证明了CSAMT方法在该区的深部地质信息探测中是一种行之有效的方法。
This paper describes the application of the controlled source audio frequency magnetotelluric sounding （CSAMT）in search for deep geological structure in Zoujiashan area,Xiangshan volcanic basin. The results show that the CSAMT method divided the boundary of different groups and the basement interface, identified three faults, revealed the morphological characteristics of underground rock and structure successively above the depth of 21300 m. The boundaries of different groups divided by CSAMT method agree well with the actual locations, as shown by the comparison with drilling information. The results show that the CSAMT method is effective in the deep geolog- ical information detection in this area.
