摘要
The EH4 electrical conductivity imaging system which is characterized by portability, high-efficiency and high-resolution, and can penetrate large exploration depths and low-resistivity covers to show the spatial distribution of the deep-seated geological bodies, is an electromagnetic observation system of hybrid field sources in the frequency domain. In the exploration of deep-seated ore-controlling structures in the Xiaoniuchang area in Tong’an, southwestern Sichuan Province, the EH4 electrical conductivity imaging system was employed for the profile processing and interpretation. The findings of the concealed structures and stratigraphic boundaries in the study area reflect the effectiveness of the EH4 electric conductivity imaging system for the exploration of the deep-seated concealed structures and stratigraphic boundaries.
