摘　　要：可控源音频大地电磁法(CSAMT)是以有限长接地导线为发射源,在距发射源中心一定距离处同时观测电场、磁场参数的一种电磁探测方法。这里以CSMAT法在某地区铁矿勘探中的应用为实例,说明该法在铁矿勘探中是有效可行的,并就CSMAT方法在勘探过程中遇到的若干问题进行了探讨,并提出了相关建议。The controlled source audio frequency magnetotelluric （CSAMT）, using limited length grounding wire as its source is a magnetotelluric sounding method. It observes the electric and magnetic parameters at a certain distance away from the cen ter of the field sources. The CSAMT has been proved effective and practical through the application in one iron ores explora tion, and the problems occurred in the process is mentioned and discussed. Some related suggestions is finally given in the paper.
