Under sustained stretching stress, extensional forced folds were formed in the overlying formations of salt beds due to their differentialsubsidence.
持续的拉伸应力作用，导致盐层上覆盖层差异沉降形成伸展型强制性褶皱。
2
While its evolution and flow direction are controlled by differential tectonic subsidence.
沉积环境的演变及主要水流方向，受差异性构造沉降的控制。
3
One-dimensional general model of land subsidence due to pumping is deduced and a semi-analytical method is used to solve this deviatoric differential equation.
