| Abstract: | This paper mainly describes the application results of the Controlled Source Audio Fre-quency Magnetotelluric Method (CSAMT) in Chanziping uranium deposit and evaluates the other telluric model. In addition,several problems such as detection depths of Cagniard ap-parent resistivity and phase difference ,the effect of low resistant intermediate layer on the detection depth and data from distal and near field of electromaenetic waves are discussed. |
