摘要：
卡特巴阿苏金铜矿床是新疆西天山近年来发现的特大型金铜矿床之一。本文对卡特巴阿苏金铜矿床矿体产出特征、矿石矿物组成及结构构造、围岩蚀变、成矿作用期次等进行了研究，对矿床的控矿因素进行了分析。通过对矿床野外地质特征研究，结合岩矿分析结果表明，矿体主要产于二长花岗岩中，受破碎带节理构造系统及岩体与大理岩地层接触带控制。节理系统中矿体为脉带状，矿石主要为细脉状、细脉浸染状、团斑状构造，蚀变以钾化、硅化、绢云母化、绿泥石化为主。岩体与大理岩地层接触带的矿体呈透镜状、似层状、巢状、串珠状，矿石主要为致密块状构造、脉状构造，蚀变以钙铝榴石化、透辉石化、透闪石-阳起石化、绿帘石化为主。矿区具有两期成矿作用，分别与二长花岗岩和闪长质岩脉有关，在空间上具有一定程度的叠加。矿床受地层、构造、岩浆作用的多重控制，为矽卡岩型-破碎带蚀变岩型矿床，研究成果为区域找矿提供了方向。
