摘　　要：西昆仑位于秦祁昆成矿域,受自然条件限制,矿产研究开发程度低,斑岩型铜矿是该区找矿难点.喀拉果如木铜矿是区内最近发现的一个斑岩型矿床.本文以野外调查为基础,对该矿床地质特征进行分析,圈定出铜矿化面积约0.25 km2,新发现4条具一定规模的铜矿体,铜矿外围发现7条铅锌矿脉.通过对该矿区地质背景、成矿条件、矿体特征、矿化信息及蚀变特征的研究,初步探讨了该矿床成因,认为具有良好的斑岩型铜矿床找矿前景.The West Kunlun region is located in the Qinling-Qilian-Kunlun metallogenic domain;the prospecting of porphyry copper deposits hasn＇t been broken through up to now for the difficult nature condition and poor extent of geologic research.The Kalaguorumu copper deposit in west Kunlun is a newly discovered porphyry copper deposit.Based on field working,4 copper ore bodies were found in 0.25 square kilometers copper mineralization,and 7 lead-zinic ore bodies were found surrounding copper mineralization.The prospecting potential of the porphyry copper deposit is good and the genesis of the deposit was discussed by means of geologic setting,minerogenetic condition,geology characteristic,mineralization information and the alteration inthe ore district.
