康古尔韧性剪切带变形特征及控矿作用

康古尔韧性剪切带具明显的遥感影像特征和区域重、磁异常变化特征。韧性剪切引起的变质作用表现为强应力下的岩石变质、变形，变质相序从绿片岩相到角闪岩相，变质岩石类型为千枚岩、片岩、变粒岩、糜棱岩及糜校岩化的岩石。韧性剪切变形和塑性流动形成的面理、线理、招皱、韧性断裂等构造形迹十分明显，构成一条东百长1000多千米，南北宽20～30km的狭长线形构造带（强应变带）；它经历了多期次、多种构造作用交替叠加的变化过程，按性质分类属大型平移断裂系统。康古尔韧性剪切带控制着重要的金矿、铜镍矿床及稀有金属等矿产，是新疆东部有重要找矿意义的成矿带。

DEFORMATION AND ORE-CONTROLLING MECHANISM OF KANGUR DUCTILE SHEAR ZONE

Kangur ductile shear zone is characterized by obvious remote sensillg images and regional gravity and magnetic anomalies. The metamorphism caused by ductile shearing is shown as strong-stress deformation of rocks from greenschist phase to hornblelld phase, Including phyllites, schists, metagranulites, mylonites and mylonitic rocks. The clear tectonic indications composed of foliation, lineation, folds and ductile faults formed by ductile shearing and plastic flowing make up a long narrow structure zone (strong strain zone) over 1000 km long from east to west and 20~30 km wide from south to north. The structure zone went through multi-phase and repeated tectonic overlappings, and is classified as a large-scale horizontal slip fault system.Kangur ductile shear zone as a significant mineralization zone of the eastern Xinjiang controls important gold deposits, copper-nickle deposits and rare metals.
