Institute of Geological Survey, Central South University, Changsha 410083, China) Abstract: A variety of electromagnetic exploration methods, involving the wide field electromagnetic method, the audio magnetotelluric method (AMT) and the controlled source audio frequency magnetotelluric method (CSAMT), were carried out on a known geologic profile of a gold mine in Shandong Province, with the purpose of comparison in the real exploration effects. Through the comparison of the exploration results, from the same section, it is found that the wide field electromagnetic method has advantages of shallow high resolution capability, strong anti-interference ability and high survey efficiency compared with AMT, and it is better than CSAMT in the exploration depth, anti-interference ability and working efficiency. However, the study and research should be moved further including
