The Denggezhuang gold deposit is one of the most typical quartz vein gold deposits in the Muping-Rushan metallogenic belt in Jiaodong Peninsula. Based on a study of the “three in one” ore-forming model, the authors hold that the formation age of the vein rock is the same as the ore-forming age, and this vein rock and early Cretaceous magmatic rock are respectively Ⅰand Ⅱ grade ore-forming geological bodies. Jingshan Group metamorphic rock served as the activator, Jiaodong Group partially provided ore materials, magmatism provided heat source for multiple ore-forming fluids, and fractures played the role of dynamics and location space.
