Abstract: Abundant geothermal resources are stored in the Huhhot-Baotou Basin of Inner Mongolia Autonomous Region,which are mainly developed in the northern part of the basin.In order to find out the geothermal geological conditions in the southern part of the basin,the CSAMT method combined with 2D seismic method were used to conduct the geothermal resource exploration.Based on the measured data inversion,in combination with geological data and the full use of technical characteristics of different geophysical prospecting methods as well as the analysis and comparison of information concerning electrical property,stratum,fracture and hydrogeology of electrical structure and seismic site,the integrated interpretation is achieved with comprehensive research results.The distribution,geological structure and other geothermal geological conditions of the deep-seat faults in the exploration area were preliminarily ascertained.The study results provide the basis in geophysical prospecting and geological survey for comprehensive assessment and prospect forecast of geothermal resources in the basin.
