英文摘要	Eastern North China Craton (NCC) is connected with Korean Peninsula, constituting an important part of Sino-Korea Craton. Different scales of gold deposits with significant regional characteristics have been found in the Jiaodong Peninsula of NCC and Korean Peninsula. More than 200 gold deposits/spots within Jiaodong Peninsula, including world-class Sanshandao, Jiaojia, Xincheng and Linglong gold mines, have been explored. Two types of gold deposits at Jiaodong are widely accepted, namely quartz vein-style and structurally controlled altered rock-style. Geochronology demonstrated that these gold mineralizations were happened in a short time interval around 120Ma. All gold deposits were formed at the same tectono-magma-fluid geodynamic background. Auriferous fluids were come from mantle-derived magma or interaction between mantle-derived magma and crust. Gold mineralization took place in the extensional tectonic settings at crust/lithosphere in the Early Cretaceous. The deposits at Jiaodong were called decratonization gold deposits. Pyonganbuk in the North Korean, adjoining Liaodong, hosts several tens gold deposits and gold resource are huge. Gold occurrence and mineralization type are similar to Wulong gold deposit in the neighbour Liaodong. This quartz vein type gold mineralization might be also connected with lithospheric thinning and craton destruction of NCC at Early Cretaceous. The gold-silver deposits in South Korea can be classified into Jurassic mesothermal and Cretaceous epithermal styles of mineralization. Gold occurrence of Jurassic lode mineralization in South Korea is similar to that at Jiaodong with remarkable discrepancy of mineralizing peak around 160Ma. The Cretaceous gold-silver deposits in South Korea were mainly formed at 100 70Ma, and associated with the subduction of the Pacific plate. The deposits are belonged to typical epithermal base metal metallogenic series related to hydrothermal systems around porphyry and sub-volcanic activity. Similarities and differences among type, occurrence and mineralizing time of gold deposits in the Jiaodong and Korea peninsulas are closely related with Mesozoic geological evolution and geodynamic setting.
