Abstract Through the electrical structure model of AMT inversion for G01 and G02 line in northern Jiling rock mass, combined with regional geology and geological profile data of No. 89 prospecting line, the authors basically clarified the electrical structural features of the hanging and lower walls of Geminggou fracture, and then inferred its location, attitude, deep extension and some other information. The results show that AMT can objectively reflect the electrical distribution pattern of geological body in the underground half-space of the section, and it can also reveal the structural features of ore-controlling structure, i.e., the Geminggou fracture. The hanging wall is reflected as tongue-like low resistance band that extends to the depth, while the siliceous marble and breccias developed close to the lower might reflect a wedge-shaped high resistance body that is narrow at the top and wide at the bottom, This can strictly control the strike and distribution pattern of ore-bearing siliceous marble and breccia.
