The "delaminating contraction" means that different structural levels developed their own contractional structural style owing to the detachments caused by the salt rock of PaleoceneEocene and the coalbearing series of Jurassic. The "vertically stacking" means that the stronger deformation zones within various levels were stacked up vertically, and the thinskin contractional deformation of cover detachment was stacked up on the top of the basementinvolved contractional deformation, so that the detachment fault could not develop into a regional detachment fault with great horizontal displacement.
