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。
EH4 conductivity imaging system is a mixed-source frequency domain electromagnetic observation system that penetrates low-resistance overburden and clearly reflects the spatial distribution characteristics of deep geological bodies. It has the characteristics of light and efficient, large exploration depth and high resolution. In the prospecting of the ore-controlling structures in the Tong’an-Maoniuchang area of Sichuan, using the profile processing and interpretation results of the EH4 conductivity imaging system, the hidden structures and stratigraphic boundaries in the area were identified. It is proved that the EH4 conductivity imaging system is in the process of finding hidden structures and Validity in the process of geological boundary.
