Abstract

Abstract

In order to explore the influence of the Nenjiang-Balihan fault zone in the study area, the authors made field structure elements measurement and comparative study of Ulanhot regional ductile deformation zone and, on such a basis, put forward the argument that the study area is at the sinistral strike-slip deformation stage. Through the study of the toughness deformation characteristics of the ductile shear belt, the deformation stage of shear band is defined as the initial mylonite and mylonite. Based on previous researches and related chronologic data, the authors hold that the slip time was Early Cretaceous (139~113 Ma). It is of great significance to further clarify the macroscopic characteristics of the fracture zone and the formation time.
