The surface loading of the mountains and the associated root of thickened crust produce horizontal deviatoric tension in the strong upper crust . in contrast , the deep , dense lithospheric root and its associated downflexing of the surface produce horizontal compressive deviatoric stress in the strong near - surface layer . the actual state of stress in the strong layer of the upper crust is the combined effect of these two opposite stress systems together with bending and other local and regional stresses such as due to ridge push
模拟结果表明：由于均衡机制，造山带下部的低密度山根促使地壳隆升、造山，山根是地壳刚性层中张性构造应力的主要力源；与此相反，冷的高密度岩石圈向软流圈插入、拆离、下沉，从而形成岩石圈根，它引起挤压造山和岩石圈地幔物质的重新调整，也是地壳刚性层中挤压性构造应力的主要力源。
