摘　　要：卡特巴阿苏金铜矿床地处新疆西天山那拉提构造带的北缘,矿区侵入岩发育,二长花岗岩是其主要的赋矿岩石。卡特巴阿苏金铜矿富矿二长花岗岩最新SH R IMP锆石U-Pb年龄为359.8Ma±5.2Ma,显示其侵入时期主要发生在晚泥盆世。通过对该矿地质特征进行分析与研究,显示该矿成矿过程中存在多期次构造控矿的特征,并且区内的断裂以及节理裂隙对其成矿也起着明显的控矿作用。文中对该矿床地质特征及成矿环境进行分析探讨,旨在为矿区找矿工作提供理论参考。The Catabaasu gold-copper deposit is located in the northern margin of the Nalati structural belt in the western Tianshan Mountains of Xinjiang, where intrusive rocks are well developed and monzonitic granite is the main ore-hosting rock. The latest SHRIMP zircon U-Pb age of monzonitic granite in the Katbaasu gold-copper deposit is 359.8 +5.2 Ma, indicating that its intrusion occurred mainly in the Late Devonian. Through the analysis and study of the geological characteristics of the deposit, it is shown that there are many stages of structural ore-controlling features in the mineralization process of the deposit, and the faults and joints in the area also play an obvious role in ore-controlling. In this paper, the geological characteristics and metallogenic environment of the deposit are analyzed and discussed in order to provide theoretical reference for ore prospecting work in the mining area.
