Description of a NW-trending brittle shear zone, Ulaanbaatar, Mongolia
摘要
A fault trending NW-SE from central Ulaanbaatar to Nalaikh, Mongolia, has been inferred from a topographical viewpoint, however, its lithological and kinematical characteristics remain uncertain. This paper describes the lithology and kinematics of this fault. The rocks of the Gorkhi Formation are intensely fractured to form a brittle shear zone sub-parallel to the topographical lineament from central Ulaanbaatar to Nalaikh. The fractured rocks are partly foliated with vertical planes striking N 15˚ to 30˚W. The shear zone extends for ca. 40 km north from Nalaikh. Dragging fold and P−Y fabric of the fractured rocks show top-to-the south sense of shear.
