Porphyry and skarn Au-Cu deposit, consisting of a Cretaceous (Yanshanian) porphyritic granodiorite (138 Ma, U-Pb; 113 Ma, K-Ar) body emplaced into Triassic limestone and argillaceous dolomite along the axis of a syncline. Irregularly shaped massive sulphide to disseminated orebodies are concentrated along the contacts between granodiorite and Triassic carbonate country rock.
