plastic rock

The result is that, 3 basic conditions of slope, plastic rock and regional tectonic stress field were necessary for forming of detachment fault;

结果认为：形成滑脱断层需具备斜坡、塑性岩体和区域构造应力场3个基本条件；

And this pressure forced the Earth's mantle, the layer of hot, plastic rock that's located beneath the Earth's crust, to give way and ooze out and sideways.

这种压力迫使地球的表层，也就是位于地球表面硬壳下面的热的，可朔的岩石层下陷，泄漏，倾斜。

If diastrophe happened in the meantime, tectonic force due to the crust movement would drive the plastic rock deforming plastically to form gneissification intrusive rock.

此时，若发生了地壳运动，地壳运动的构造作用力，使正（半）结晶的可塑相岩体发生可塑相变形，形成片麻化岩体；
