Kogan fault is treated as the boundary between the Tarim block and the West Kunlun orogenic belt. It is the division of the ancient continental margin uplift and geosynclinal fold belt. The trend of the fault is overall NW-SE.Mak-ing full use of high spatial resolution worldview-2 multispectral images is propitious to remote sensing geological inter-pretation in order to recognize the distribution of the kogan fault.Joints analysis and micro-structural observation are made to prove that the kogan fault is the dextral thrusting ductile shear zone. Before the Mesozoic, the kogan fault turns into Thrust nappe structure. In the Mesozoic, it gradually transforms into the ductile shear zone.% 柯岗断裂是划分塔里木地块和西昆仑造山带边界断裂,也是分隔铁克里克古陆缘隆起和恰尔隆-库尔良优地槽褶皱带界线断裂。断裂总体呈NW向,弧形展布。运用高分辨率遥感数据对柯岗断裂进行宏观展布分析,通过节理分析、显微构造观察,结合应力分析和构造演化解析,证明柯岗断裂是右行逆冲韧性剪切带。中生代前柯岗断裂为逆冲推覆构造,中生代后逐渐转为韧性剪切带。
