Structural Controls and Temperature-Pressure Conditions

The gold-bearing quartz veins are commonly accompanied by felsic dykes, whose orientations are controlled by shear zones. The dykes were previously interpreted to be emplaced before the development of shear zones and genetically unrelated to the quartz veins. New observations suggest, however, that felsic dykes and quartz veins are coeval.
