Abstract: The gravity, magnetic, and electrical methods have been used to reveal the structure developed in the deep covered area of the Hetao Basin. We have carried out a lot of research on the characteristics of the northern and southern boundary faults, the features and thickness of Quaternary sediments and the structures developed in the basement of the Hetao Basin. A preliminary study on the distribution of Quaternary aquifer in this area was made by using electrical resistivity method. The joint inversion results of gravity and magnetic data, and earthquake data have been analyzed. And four concealed fault F₁ to F₄ from south to north and Langshan-Seertengshan piedmont fault F₅ have been revealed. The fluctuation and buried depth of the crystalline basement in the area have been revealed. Depth of the basement in the southern part of the study area is about 2.5~4.2 km, and which in the northern part is up to 6 km. North Adjacent to the Seertengshan piedmont fault, the basement rock has been uplifted to about 0-1 km.
