摘　　要：对西藏隆子县柯月铅锌多金属矿床进行可控源音频大地电磁测深（CSAMT）法探测实验,结果显示已知含矿断裂构造相对围岩表现为明显的中低阻特点,并赋存在电阻率为400~800Ω·m的电性区。根据电阻率等值线分布形态,推断了含矿构造的深部展布,推断结果与后期钻孔工程揭露结果吻合较好。本次工作结果表明,当矿床或含矿构造具有一定规模、电性特征较明显时,利用CSAMT法对其进行深部探测能取得较好效果,该方法可在测区外围或邻近矿区系统开展。The experiment of controllable source audio frequency magnetotelluric sounding（CSAMT）for Keyue Pb-Zn polymetallic deposit in Longzi County of Tibet shows that the known ore fracture structure manifests the obvious media-low resistance characteristics and their resistivity value exists between 400-800Ω·m.According to the distribution form of resistivity isoclines,the deep distribution of the ore structure is inferred,and the inference results coincide with the later drilling.The results of the work show that when a deposit or ore structure has a certain scale and the electrical characteristic is obvious,CSAMT method,used for deep detection,can obtain a good effect,so this method can be carried out in the peripheral part of the surveyed area or adjacent mining system.
