中文摘要:胶东型金矿是不同于国际已知类型的独特金矿类型, 深入研究其成矿系列有助于深化理解矿床成因和指导找矿。本文综合分析了胶东金(银)、有色金属矿床的类型、空间分布、形成时间和成因, 划分了成矿系列, 列举了应用成矿系列指导找矿的案例。将胶东地区早白垩世与壳幔混合岩浆活动有关的金矿床、金及多金属矿床和有色金属矿床划归为胶东型金矿成矿系列, 进一步划分了Au(Ag)矿床成矿亚系列(125~115 Ma)和Cu-Pb-Zn-Mo矿床成矿亚系列(118~110 Ma), 认为两个成矿亚系列为连续发生、且有时间重叠的成矿事件。成矿系列理论有效指导了胶东地区的找矿工作, 根据石英脉型金矿和蚀变岩型金矿的成因联系在玲珑金矿田发现了台上—水旺庄巨型金矿床, 受胶莱盆地东北缘金矿床类型的启示发现了辽上黄铁矿碳酸盐脉型金矿, 在荣成有色金属成矿小区外围发现了大邓格金多金属矿床, 根据五莲七宝山金铜矿床探明了敞沟—杏山峪银铅锌矿床。

Metallogenic Series of Jiaodong Type Gold Deposits and Its Prospecting Cases
Abstract: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.
