DUCTILE SHEAR ZONES FORMED BY DIFFERENT MECHANISMS
-
摘要: 笔者通过对山西省早前寒武纪变质岩区的花岗质岩石（均一的）中的韧性剪切带研究，初步将变窄和变宽韧性剪切带特征进行了总结，认为混合岩化作用是伸展构造作用下变宽韧性剪切带岩石发生的“自分异作用”。Abstract: On the basis of a study of ductile shear zones in granitic rocks in an Early Precambrian metamorphic terrain of Shanxi province the author preliminarily summarizes the features of narrowing and widening ductile shear zones. It is considered that migmatization is ″,self-dif-ferentiation″ causing rocks of widening ductile shear zones to occur under the effect of exten-sional structure.
