摘　　要：喀依孜钼矿位于秦祁昆成矿域的西昆仑北部,矿区围岩蚀变发育,明显分为钾化带、绢云母化带、褐铁矿化带,矿体主要为褐铁矿化辉钼矿.本文选取喀依孜钼矿成矿有利部位进行EH4连续电导率剖面测量,结合成矿地质背景及控矿构造因素,对其深部进行成矿潜力预测.解译剖面显示矿化受断层控制,低阻异常与地表矿化带分布情况吻合,结合地质-物探解译剖面,推测串珠状低阻体为矿致异常,揭示深部找矿前景良好.The kayizi molybdenum deposit located in the northern part of the West Kunlun region which belongs to the Qinling-Qilian-Kunlun metallogenic domain.The wall rock was well alterated,and was classified into the following types：potassic alteration zone;sericitization zone;limonitization zone.The ore-body was mainly pyritized molybdenum.Combining the geological background with the ore-controlling structures,the survey of EH4 electrical conductivity image system was made in the advantageous metallogenic position in order to make a deep comprehensive geophysical interpretation.The result shows that the mineralization was controlled by the mainly fault;the low-resistance anomalies was consistent with the mineralization zone in the surface;the moniliform anomalies was most possibly caused by molybdenite and has a good prospect for exploration.
