库车褶皱冲断带是由印度板块和欧亚板块碰撞形成的新生代再生前陆盆地，沉积古近系和新近系两套盐岩，在其西部发育盐底辟构造。根据野外地质调查、地震剖面解释以及平衡剖面制作，探讨了库车褶皱冲断带盐底辟的成因机制。库车褶皱冲断带盐底辟分为两种类型：沿喀拉玉尔滚走滑断层发育的点状盐底辟构造盐栓；发育在吐孜玛扎地区的线状盐底辟构造盐墙。库车褶皱冲断带西段盐上生长地层主要发生在库车组中段沉积期及以后，库车组中段发育角度不整合面，反映盐底辟的形成。盐栓受走滑作用的控制，为走滑拉张作用的产物，而盐墙受库车组中段及其后差异压实作用的控制，受挤压作用的改造。

Kuqafold thrust belt (KFTB)is a Cenozoic rebuilt foreland basin formed by the collision between Indian and Eurasian plate.Kumugeliem Group (K.G.)and Jidike Formation (J.F.)salt was sedimented during Paleogene and Neogenere spectively and salt diapir was developed in the west of KFTB.Field survey,seismic profile interpretation and balanced section were analysed for the mechanism research of salt diapir.Two types of salt diapirs were recognized in the west of KFTB.One is the salt stock developing along Kalayuergun strike-slip fault and the other is the salt wall located in the Tuzimaza area.The growth stratigraphy of the west KFTB was mainly developed in the middle of Kuqa Formation and its upper layers.The unconformity was developed in the middle of Kuqa Formation,showing the development of the salt wall.The salt stock is controlled by the strike-slip;and the tensional stress component of strike-slip caused the salt extruding to the surface.The salt wall is controlled by the sediment differential loading.The huge different sediment thickness made the salt star to develop.The salt wall continued to develop in the later period and the infected by the thrust fault.
