摘　　要：以印尼某铁矿区为例,说明AMT法寻找隐伏铁矿的有效性。配合磁法,利用AMT法的低阻体圈定隐伏磁铁矿,为钻孔设计及矿山开发提供了物探依据,在国际化的商业勘查中取得了良好的勘探效果。Exemplified by the exploration of a certain iron deposit in Indonesia, this paper deals with the effectiveness of the audio fre- quency magnetotelluric sounding （AMT） method in search for concealed iron deposits. In combination with the magnetic method, the low resistivity body of the AMT method was utilized to delineate the concealed magnetite body. The results provided geophysical basis for drill hole design and mine development and achieved good exploration effect in international commercial exploration.
