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 2000 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 geological information detection in this area.
