| Tartalmi kivonat: | Deposits of many types are known in Korea, apparently none of notable size. They are found in the southeastern and central parts of South Korea and occur in Precambrian, Paleozoic, Mesozoic and Cenozoic rocks. Hydrothermal fissure filling deposits, hydrothermal replacement deposits, sedimentary deposits, and supergene epigenetic deposits are found. The hydrothermal deposits are associated with base-metal ores and also with gold-silver ores, which increase in tenor with depth as thé manganese, usually in the form of rodochrosite, diminishes in tenor. Minor manganese oxide deposits associated with spilitization of andesite occur. One sedimentary bed of manganiferous rock intercalated into Precambrian dolostone ranges from 0.5 to 0.1 m in thickness'.q.ver an outcrop length of 9 km; unfortunately the rock has been metamorphosed and contains: a;,high percentage of silicates of no economic value as well as manganese carbonate. |
