The Western Dinosaur Park of the Lanzhou New area, located in the Lanzhou-Minhe Basin, has encouraging prospects for geothermal exploration, development, and utilization. Based on the previous results of regional geological structure and geothermal characteristics, this study further investigated the geothermal reservoir horizons and the geothermal geological conditions using both the controlled source audio-frequency magnetotellurics (CSAMT) and the magnetotelluric sounding. Then, available geothermal water with suitable temperatures was discovered by drilling. Based on the geophysical exploration and drilling results, this study deduced and explained the structure and pluton distribution of the study area, analyzed the geothermal geological conditions, and pointed out the future exploration direction. The results of this study can be utilized as a reference for geothermal exploration in adjacent areas of the Western Dinosaur Park and similar areas.
