新疆西天山卡特巴阿苏金铜矿区构造特征研究

摘要

卡特巴阿苏特大型金铜矿床位于新疆西天山那拉提北缘断裂的南侧,紧邻那拉提北缘断裂.对矿区构造地质特征进行了详细研究,对构造与成矿作用的关系进行了分析.研究结果表明,矿体主要分布于F5、F6断层之间的断层-破碎带节理构造系统中,显示出典型的构造控矿特征.通过对矿区构造与区域构造关系的探讨,认为矿区构造系统为与区域性那拉提北缘断裂的次级平行构造,因此该矿区构造体系为与区域性构造平行的一套断层破碎带-节理构造系统.%Located in the south of Nalati north rim fracture in Western Tianshan Mountains,Xinjiang,Kateba'asu deposit is an exceptional large Au-Cu deposit adjacent to Nalati north rim fracture.The study focuses on the structur-al geological characteristics and the relationship between the structure and mineralization in mining area.The results indicate that ore bodies are mainly distributed in the joint structure system in the fault-fracture zone between F5 and F6 ,and show typical structural ore-controlling features.On the basis of the study on the relation of the structure of min-ing area and regional structure,it shows that the structure of mining area is the secondary parallel structure of Nalati north rim fracture.So the mine field tectonic system is a set of fault fracture zone-joint system,parallel to regional structures.
