Abstract: The Engh Had ductile shear zone occurs in the glutenite of Middle Jurassic Xiufeng formation in Mohe basin in the northern part of Daxinganling Mountains.The geometric,kinematic and dynamic characteristics show that the ductile shear zone is dextrally slanted thrust shear zone from northwest to southeast.In the condition of compression from south to north,with a heat source provided by the syntectonic acid intermediate magmatic rock, the ductile shear deformation took place in the glutenite of Xiufeng formation along or across layers.At the same time,the strong ductile deformation promoted the activation and migration of Au in the glutenites.The ductile deformation zone and derived brittle structures perform the transferring channels for ore forming fluid and space for ore deposition.
