Metallogenesis in Korea

筆者는 1981年 파리, 1983年 마닐라에서 개최되었던 CGMW會議에 參席함을 계기로 世界共通의 製作規約을 遵守해 가면서 大韓地質圖 및 한국의 地體構造圖를 基本圖로 하여 그간의 鑛床調査硏究資料中 444個 主要對象鑛床을 選定, 이들 資料를 整理綜合 分類하여 1983年에 한국의 鑛床生成圖를 發刊(韓國動力資源硏究所)한 바 있다. 처음 試圖된 일이었을 뿐 아니라 對象個個 鑛床의 精密調査資料가 不足하여 恰足하지 못하였음에 次後 보다 補完된 充實한 內容의 鑛床生成圖를 期待하여 마지 않는다.

In order to make preparation of the Metallogenic Map of Korea, the writer have to collect and review the data of general geology and ore deposits of Korea which have been published up to date. The geology of Korea has been briefly simplified and grouped into the 15 formations so as to provide the base geologic map for making the Metallogenic Map of Korea. Geologic provinces of south Korea are divided into four, that is, Gyeonggi-Ryeongnam province, Ogcheon geosynclinal province, Gyeongsang basin province and Tertiary province. In the view of tectonics and related granites, the major orogenies in south Korea are as follows; Ryeongnam orogeny, Taebaeg disturbance, post-Sangweon disturbance, post-Joseon disturbance, Bulgugsa disturbance and Yeonil disturbance. Metallogenic epochs might coincide with the period of syntectonic or subsequent igneous rock intrusions accompanied with the above listed orogenies and disturbances. Thus, metallogenic epochs that are certain in Korea so far are; Precambrian periods, Paleozoic periods, Jurassic to early Cretaceous periods, late Cretaceous to early Tertiary periods, Quaternary periods and age-unknown periods. The Metallogenic Map of Korea shows 444 ore deposits and/or mines by symbols on a background adopted from the existing geologic and tectonic map. The 444 metallic and non-metallic deposits are categorized by the commodities they contain, size, geologic environment, mineralized age and mineralogic nature.
