The ore controls on the Dongkeng gold deposit in Guangdong

The Dongkeng gold deposit is located in the silicified quartz vein belts of the green schist belts in the middle subgroup of the Sinian Yunkai Group, and constrained by the NW-trending ductile shear zones. The sulfur, heat and gold in the gold deposit are derived mainly from the magmatic rocks. The contact zones of the gold deposit are believed to be favourable sites for the accumulation and filling of the ore vein groups. The ore controls include stratigraphy, tectonics and structures, magmatic rocks, lithologic associations and migmatitic contact zones.
