| Abstract: | Based on characteristics of the ductile shearing zones and Au mineralizations in the south belt, this paper discusses the control of ductile shearing zone on Au mineralization, genetical mechanism and ore-searching direction of the ductile zone type Au deposit. Combination of Au-bearing metamorphic rock sequence, medium-low temperature ductcle-brittle shearing and intermediate-acidic granite is the ore-searching mark. Distribution, size and morphology of the Au deposits are dominated by the ductile shear zone. |
