| 摘 要： | 以盐构造解析的方法,综合地震与地质资料,表明库车坳陷新生界中的盐上断层受控于褶皱作用。盐上地层首先发生褶皱变形,随着褶皱作用的加强,然后发生断裂作用,盐上构造层的变形方式为褶皱相关断层,其变形特征不同于断层相关褶皱。从断层成因机制可见:断层相关褶皱理论不适用于库车新生代坳陷盐构造发育区。库车坳陷膏盐层的发育造成盐上构造层与盐下构造层变形有差异,盐上构造层以褶皱作用为主,盐下构造层以冲断作用为主。库车坳陷盐上构造层主要为褶皱相关断层,发育张性断块、后翼突破断层、前翼突破断层及褶皱相关断层组合等构造样式,根据盐上构造层的变形特征总结了褶皱相关断层的演化。

| Abstract: | There were three structural layers in the Cenozoic Kuqa Depression,in ascending order,the salt-underlying beds,the salt(or gypsum) beds and the salt-overlying beds.The salt structures were well developed and resulted in the structural deformation of the salt-underlying and salt-overlying beds being obviously different.The thrusting dominated the salt-underlying beds,while in the salt-overlying beds the deformation was mainly folding.The surface geological survey and seismic profiles showed that the salt-overlying beds was folded first,then the faulting developed with the strengthen of folding action.The deformation characteristics of the salt-overlying beds might be fold-related faulting,instead of the fault-related folding which was not applicable in the salt structure-developing areas in the Kuqa Depression.The patterns of the fold-related faulting in the salt-overlying beds included the extensional block,back limb break-up fault,front limb break-up fault,and the combination of them.The mechanism and evolution of the fold-related faults was discussed according to the deformational features of the salt-overlying beds in the Kuqa Depression. |
