摘　　要：利用音频大地电磁测深(AMT)在泸沽湖地区进行地热资源勘查,在分析地热形成条件的基础上,通过音频大地电磁测深和大地电磁测深(MT)数据联合反演,结合地热资源赋存有关的水文地质条件,对反演图件进行推断解释,查明了区内主要断裂构造位置、产状、规模及地下热储层深度,取得了较好的应用效果。Audio Magnetotelluric(AMT)method has been applied in exploring geothermal resources in Lugu Lake area.On the basis of analyzing the forming conditions of geothermal resources,magnetotelluric sounding and audio magnetotelluric sounding data are jointly inversed and the hydrogeological conditions combined to inerpret and infer the inversion map.Location,occurrence and size of major faults and depth of the geothermal reservoirs in the study area are made clear.The application result is good.
