摘　　要：我国东北森林覆盖区地表植被发育,低阻盖层较厚,岩石露头少,常规直流电法低阻屏闭影响严重。EH4连续电导率测量系统具有勘探深度大、轻便高效、结果反映直观等特点,它可以穿透低阻覆盖层清晰的反映深部地质体和构造的展布特征,结合地质成矿理论,指明成矿有利地段,为后续地质找矿工作提供理论依据。The Northeast of our country, being a forest - covered areas, where vegetation grows fully and covers heavily, low - resistivity overburden in this areas is thick and rock outcropping is sparse. So, shielding effect is strong with conventional galvanic resistivity method. The system of EH4 continual electric conductivity characterizes deep - exploring , portable , effective and result - visual and penetrates the low- resistivity overburden and displays geological bodies and structures＇ pattern in the depth. Combining geology metallogenic theory, it indicates the favorable mineralizing areas, being a theory basic of the geological prospecting in future.
