PUBLICATIONS OF GEOLOGICAL MAPS BASED ON GEOLOGICAL INFORMATION STANDARDIZATION
Since the last publication of the Geological Map of Korea (1:1,000,000 scale) in 1995, a considerable amounts of new geologic and stratigraphic information, largely based on high-quality age data, have been accumulated. This necessitate a revision of the map reflecting new findings and researches on the geology of Korea. The new, revised edition of the Geological Map of Korea (1: 1,000,000) is planned to be published in 2019. This year a revised version of the distribution of Precambrian rocks in Korean Peninsula has been completed on the basis of a systematically classified legend to reflect all of the new geological information. In particular, the revised Precambrian geological map includes new geological and stratigraphic information on the Late Paleoproterozoic to Meso-and Neoproterozoic supracrustal and intrusive rocks found along the western coastal area of the peninsula.
In addition to the revised Geological Map of Korea, a series of tectonostratigraphic maps are to be published on a scale of 1:100,000 along the western coastal areas of the central Korean Peninsula, because of the geological and tectonic importance of these areas due to the occurrence of unusual, high-pressure rocks, such as Meso- to Neoproterozoic supracrustal and intrusive types that are rarely found on the mainland. The Tectonostratigraphic map of the Gimpo-Incheon area (1:100,000 scale) was published this year.
