摘　　要：EH4电导率成像系统是一种混场源频率域电磁观测系统,其能穿透低阻覆盖层并清晰反映深部地质体空间展布特征,具有轻便高效、勘探深度大、分辨率高的特点。在对四川通安-小牛场地区控矿构造勘探中,利用EH4电导率成像系统剖面处理与解释结果,查明了区内隐伏构造及地层界线,证明EH4电导率成像系统在寻找隐伏构造与地质界线过程中的有效性。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,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.
