Geothermal energy is the focus of clean energy exploration,development and utilization.The Tongren Basin in Qinghai Province was selected for geothermal geophysical exploration practice.Firstly,based on the 1:50 000 high-precision magnetic survey data,combined with regional geological data,the range of fault structures and hidden rock masses was divided,and the geothermal anomaly target area was delineated.Through the combination of geophysical methods,mainly using micro motion detection method and supplementing controllable source audio magnetotelluric method in areas with low electromagnetic interference,it has been basically de-termined that the geothermal exploration type in Tongren Basin is type Ⅱ-3,which has both layered and banded thermal storage charac-teristics,mutual generation relationship,and relatively complex geological and structural conditions.The research has pointed out the direction for subsequent geothermal resource exploration in the area.
