摘要
大陆地壳结构具不均一性，由此表现出分层性。深成构造作用是应变局部化的过程，表现为韧性剪切变形作用。地壳中近水平或网络状反射体韧性剪切带的产生，为深成构造作用的结果。地壳结构的特点和深成构造作用都与大陆岩石圈流变性有密切的关系。另外，熔融作用对深成构造作用及岩石流变性也有重要的影响。
The continental crust is structurally inhomogenous, and shows several levels. And the hypogene tectonism in the continental crust is a process of the strain localization, and results in the ductile shear zones, which are related to the sub-horzontal or an asfomozing reflections. Acturally, the features of the continental crust and hypogene tectonism have a very close relationship with the lithospheric rheology, and have been constrained by the rock rheological behavior in the lithosphere. In addition, melting also play an important role in the hypogene tectonism and rock rheology.
