Abstract

Abstract

The regional geological mapping in Beishan, Guyang County, Inner Mongolia, indicates the presence of the ductile shear zones in the Neo-Archaean quartz diorite and the Meso-Proterozoic tonalities. The field investigation, strain measurement, indoor micro-structure and electronic probe show that this ductile shear zone occurs as two groups of conjugate combinatorial shear zones. The formation mechanism of this conjugate shear zone, a simple shear that occurred at the end of the Meso-Proterozoic in the falser environment, is related to the compression between the Siberia plate and the North China plate. The metamorphic facies of this conjugate shear zone is the greenschist facies.
