  • Based on the regional geological analysis,we know that there are 3 large-scale ductile shear zones from north to south in the studied area,which were caused by the collision and continual extrusion between South Plate and North Plate during the late Paleozoic Era.The ductile shear zones controlled the distribution of the gold deposits in the area.Three ductile deformation periods could be marked out from the late Variscanic period to the early Yanshanian period,and accompanied by gold activation,transfer and enrichment for different stages.The shear of deeper earth's crust andmagmatic activities provided the heat power andm inerallogenic elements and hold space for gold mineralization.The characteristics of gold vein (in Bayanwenduer shear cane) show that the fissures in shear canes are the favoredplace for enrichmentof Au element.Them etallogenic model of gold deposit related with ductile shear canes in Sunitezuoqi area,and ore-founding direction for gold are put forward.
