形成旋扭构造的动力可概括为五个方面:地块随着地球自转速率的变化,局部发生的旋扭;漂移在软流圈之上的地块遇到上拱的“热柱”受到局部牵制而旋扭;地幔熔融体物质对流循环产生蠕动式旋扭;岩石圈拖曳牵动引起旋扭;重力控制下密度分异所引起的水平漫流碰接于上升物质而旋转。欧亚大陆上分布着涡轮状、帚状、莲花状、连环状等各种旋扭构造。
The power to form the twist structure can be summed up in five aspects: the local rotation of the block with the rotation rate of the earth; the “hot column” encountered by the parcel above the asthenosphere encountered by the local And the twist and twist. The creeping twists and turns caused by convection and circulation of the molten material in the mantle and the twisting caused by the dragging of the lithosphere, and the horizontal diffusions caused by the density differentiation under gravitational control touch the ascending material and rotate. Eurasian continent with the distribution of turbo-shaped, broom-like, lotus-shaped, chain-like structure and other twist.
