摘　　要：小哈拉军金铜矿床位于天山山脉西段的那拉提山北坡,地处伊什基里克裂谷与伊宁地块的结合部,其上叠加石炭纪岛弧,成矿位置较为特殊,且矿床蚀变类型复杂,具有一定的典型性。本文基于该金铜矿床最新工作成果,对成矿地质条件、物化探异常特征、矿化蚀变特征等进行了阐述,对其形成时代及矿床成因进行了探讨,初步建立了地质-地球化学-地球物理综合信息找矿勘查模型,其对该区外围寻找同类型矿床具有一定的参考意义。The Xiaohalajun Au-Cu deposit is located on the north slope of the Nalati Mountain in the western part of the Tianshan Mountains at the junction of Yishijilike Rift Valley and Yining Block.On the junction is superimposed the Carboniferous island arc.The deposit occurs in a special location with complex alteration types.This paper is based on the latest work results to describe the metallogenic geological conditions,geophysical and geochemical anomaly characteristics,mineralization-alteration characteristics and discusses the metallogenic age and genesis of the deposit.A integrated geological-geochemical-geophysical information-based prospecting model is built to provide reference for prospecting similar deposits in surroundings of the Au-Cu deposits.
