| Abstract: | The southeast of Korea has attracted considerable attention in the geologic community because of its extensive igneous activity and associated mineralizations from the Late Cretaceous to the Early Tertiary (Cu, Pb-Zn, W-Mo, Bi and Au-Ag hydrothermal-vein deposits, porphyry, skarn and altered clay deposits). The southeast of Korea is composed of Cretaceous sedimentary Gyeongsan basin, volcanic and plutonic rocks. Most of the mines are either closed or incapable of producing more ores because of their poor reserves. The south of the Gyeongsang basin is famous for its hydrothermal altered clay deposits associated with volcanism. In order to locate more metal resources, many researches have been conducted into the gold-silver mineralization within hydrothermai-altered deposits in the past several years. The age of plutonism ranges from 112 Ma to 44 Ma, and that of volcanism from 74 Ma to 47 Ma. |
