地壳在地球漫长的发展史上,曾发生过多次大的构造运动,构造带就是地壳运动发生变形留给我们的显著证据。大陆上主要有东西和南北走向的挤压构造带和北东、北西走向的压扭构造带;大洋中有拉张产生的近南北和东西走向的洋脊及其伴生的横断裂。这些构造带和构造型式,从形成和穿切关系得知,它们起源于地壳运动南北和东西方向的相对挤压和扭动。
Crust In the history of the Earth’s long development, there have been many major tectonic movements, tectonic belt is the deformation of the crust to leave us with evidence of significant evidence. On the mainland, there are mainly compressional and tectonic belts with east-west and north-south trending belts and compression-knot tectonic belts along the NE and NW directions. In the ocean there are near-north-north and east-west ocean ridges and their associated transverse faults caused by extensional tension. These tectonic belts and structural patterns, known from the relationship between formation and transversal cutting, originate from the relative squeezing and twisting along the north-south and east-west directions of the crustal movement.
