摘　　要：CSAMT法是一种使用人工场源、通过改变发射频率进行测深的地球物理方法。该方法以勘探深度大、分辨能力强、抗干扰能力强等特点成为研究深部地质特征的有效手段。文章总结了近几年来CSAMT法在沉积岩地区和火山岩地区的应用效果,主要包括推断解译基底的埋深、推断断裂的空间展布形态、二级构造单元的划分和岩性的划分等地质问题,效果较好,说明该方法是铀矿勘查的有效技术手段。Controlled Source Audio-frequency Magneto Telluric（ CSAMT） is a kind of geophysical method for prospecting by changing the transmitting frequency with the application of artificial field. This method has become an effective means to study the deep geological features due to its characteristics of large exploration depth,high resolution and strong anti-interference ability. This paper summarizes the application effect of CSAMT method in sedimentary area and volcanic area in recent years,which mainly includes the interpretation of the buried depth of basement and the spatial distribution pattern of fracture,the division of sub-tectonic units and lithology,as well as other geological problems,all got better effect. Therefore,this method is an effective technique for uranium exploration.
