| Metallogenic Series of Jiaodong Type Gold Deposits and Its Prospecting Cases |
| Jiaodong type gold deposits are unique type of gold deposits different from the internationally known type. Further study of the metallogenic series is helpful to understand the genesis of the deposits and guide the prospecting. This paper comprehensively analyzes the types, spatial distribution, formation time and genesis of Jiaodong gold (silver) and nonferrous metal deposits, divides the metallogenic series, and enumerates the cases of applying the metallogenic series to guide prospecting. The gold-only deposits, gold-plus deposits and nonferrous metal deposits related to crust mantle mixed magmatism in the Early Cretaceous in Jiaodong area are classified as Jiaodong type gold metallogenic series, and further divided into Au (Ag) deposits metallogenic sub series (125–115 Ma) and Cu-Pb-Zn-Mo deposits metallogenic sub series (118–110 Ma). It is believed that the two metallogenic sub series are continuous and time overlapping metallogenic events. The metallogenic series theory has effectively guided the prospecting work in Jiaodong area. According to the genetic relationship between quartz vein type gold deposits and altered rock type gold deposits, Taishang-Shuiwangzhuang giant gold deposit was found in Linglong gold field. Liaoshang pyrite carbonate vein type gold deposit was found inspired by the type of gold deposits in the northeast margin of Jiaolai basin. Dadengge gold polymetallic deposit was found outside Rongcheng nonferrous metal metallogenic district. And Changgou-Xingshanyu silver, lead, zinc deposit was proved according to Qibaoshan gold-copper deposit. |
