抄録

The southern half of Korean peninsula is composed geologically of Geyonggi-Yeongnam massif of Precambrian, Ogcheon group of age unknown, Joseon group of Cambro-Ordovician, Pyeongan group of late Carboniferous to Permian, Daedong group of late Triassic to early Jurassic, Gyeongsang group of Cretaceous, Yangbuk arid Yeonil groups of Tertiary, and alkaline volcanics of Quaternary. Three groups of granites are distributed in the peninsula, that is, Triassic granite series (Songrim granite series), Jurassic granite series (Daebo granite series) and Cretaceous granite series (Bulgugsa granite series). In the southern half of Korean peninsula, the latter two are widespread.<BR>The mineral deposits related to Daebo granite series are many hypothermal to mesothermal Au-quartz veins known as Korean-type gold vein. These are distributed in NNE direction. The majority of metallic and nonmetallic mineralizations in the southern half of the Korean peninsula is considered to have been formed associated with the Cretaceous granite series. The vein-type deposits are mainly emplaced in the Cretaceous sediments and intermediate volcanics in the Gyeongsang basin. Economically important skarn type deposits are found along the same horizon between shale and upper limestone of Cambro-Ordovician formation in the Taebaegsan area. The southern half of the Korean peninsula can be divided into three metallogenic provinces of Gyeonggi-Yeongnam province, Ogcheon-Taebaegsan province and Gyeongsang province.
