Gold Mineralization Characteristics of Jingjiazhuang Gold Deposit in Penglai

Honghua Huang

Abstract

Jingjiazhuang gold deposit occurred near the contact belt between Guogezhuang formation in Jiaodong group and porphyritic monzonitic granite in early Yanshan stage. Controlled by NNW fault belt, the orebodies show as stratoid. Useful compositions which are associations or paragenesis with the ore are Ag, Cu, Pb and Zn, etc. The major alteration types of its rock countries are pyritization, sericitization—quartzification and silification. The gold deposit belongs to the type of rich-quartz-vein polymetallic gold deposit.
