摘　　要：新疆卡特巴阿苏金矿区位于新疆西天山那拉提山中段,那拉提北缘断裂南侧,属那拉提Cu-Ni-Au-Fe-白云母-玉石成矿带。矿床受那拉提北缘断裂控制,就位于那拉提北缘断裂南侧次级断裂内。矿床经历了早期花岗岩体侵位成矿元素的初步富集,中期构造破碎带活动、气水热液蚀变叠加富集,晚期侵入脉岩形成的热液活动使成矿物质再次叠加富集。该矿床的发现证明,乌兹别克斯坦-吉尔吉斯坦-哈萨克斯坦的库尔干特帕-纳伦金-铁-铅-锌成矿带向东沿入我国,与那拉提中天山构造带对应。该构造带具较大找金潜力,特别是那拉提北缘断裂带是寻找破碎蚀变岩型金矿床的有利位置。The Au deposit of Kateba＇asu Located in the middle Nalati mountain,west tianshan in Xinjiang,it located in the South of Nalati North rim fault belong to the nalati Cu- Ni- Au- Fe- mica- jade metallogenic belt.The deposit is controlled by north rim fracture of nalati,and located in the South secondary fracture of Nalati The deposit have been undergoing an enrichment of Granite emplacement ore-forming element in the early stage. sthen with the faulting and Hydrothermal alteration superimposed enrichment in the middle stage,And the Hydrothermal activity made metallogenic material superposition enrichment again in the last period,.The discovery of this deposit prove the Ku Er Gan,pat-Nalun goldiron-lead-zinc metallogenic belt extending into our country,it corresponding to Nalati middle tianshan tectonic belt.This tectonic belt with large potential to find gold deposit,the Nalati north rim fault zone is a vantage point for alteration rock type gold deposit in particular.
