鸡笼山金铜矿床, 封山金洞矿田, 阳新县, 黄石市, 湖北省, 中国

Porphyry and skarn gold-copper 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.
