Large-scale gold deposit, hosted in the Hercynian Shuiquan alkaline complex that intruded Archean granulite facies metamorphic rocks and exhibits a strong petrological zoning. The main rock types are alkali feldspar syenite, quartz-alkali feldspar syenite, pyroxene-amphibole-alkali feldspar syenite, pyroxene syenite, and amphibole monozite. The 40Ar/39Ar isotopic ages of the intrusion and the K feldspars in the deposit are 327.4 Ma and 157 to 177 Ma, respectively. The deposit is controlled by the east-west trending major Chicheng-Chengde fault at the northern margin of the Sino-Korean Craton. The deposit is located within an inner contact zone of the Shuiquan alkali syenite. It consists of several tens of vein cluster that trend northeast to north to northwest. Each cluster comprises numerous parallel and oblique veins. Deposition types vary from gold-pyrite-quartz veins to gold-sulphide-quartz veins, gold sulphides in veinlets, stockworks and altered rocks. Alteration consists of K-feldspar, silica, sericite, and carbonate. Deposit and alteration are strongly controlled by faults and related fissures.
