Korean Peninsula is situated at the peripheral to marginal part of Western Eurasian Plate so that peninsula has received some degree of compression stressed from the Eurasian-Pacific Plate boundary.This paper illustrates some evidences found from the excavation sites,particularly from the upper Pleistocene sedimentary records formed since the Last Interglacial periods.The geomorphic records in coastal terrace system in the eastern part of Korea has been well documented by mapping shoreline angles along the coasts,which reveals the uplift rate assumed 0.13~0.40 mm·a~(-1)in general,even though it shows 0.1 ~1.4 mm·a~(-1) in exceptional point data.The general rate is smaller than that of Japan Island Arc and those of other western Pacific margins where uplift rates are as high as 1~2 mm·a~(-1).However it is significant that the rate is much increasing in modern GIA monitoring data in Korea.As the denudation rate of fluvial drainage basin in Korea since last 300 ka,base level lowering is computed as large as 0.14~0.25 mm·a~(-1) as shown in Jiri mountain and Donggang area.This implies that both Paleoshoreline angles and valley degradation shifted approximately at the same rate in Korea.This means terrestrial uplifting plays an important role on both coastal geomorphic process and valley degradation system.In Korea traditional glacial/interglacial climatic fluvial terrace formation,responding to both extraglacial excessive valley cutting regime and subtropical pedological geomorphic process as end-member,may be locally deviated by exceptional differential uplift. Korean Peninsula is situated at the peripheral to marginal part of Western Eurasian Plate so that peninsula has received some degree of compression stressed from the Eurasian-Pacific Plate boundary. This paper illustrates some evidences from the excavation sites, particularly from the upper Pleistocene sedimentary records formed since the Last Interglacial periods.The geomorphic records in coastal terrace system in the eastern part of Korea has been well documented by mapping shoreline angles along the coasts, which reveals the uplift rate assumed 0.13-0.40 mm · a -1 in general, even though it shows 0.1 ~ 1.4 mm · a ~ (-1) in exceptional point data. The general rate is smaller than that of Japan Island Arc and those of other western Pacific margins where uplift rates are as high as 1 ~ 2 mm · a ~ (-1) .Wowever it is significant that the rate is much more in modern GIA monitoring data in Korea. As the denudation rate of fluvial drainage basin in Korea since last 300 ka, base level lowering i s computed as large as 0.14 ~ 0.25 mm · a -1 as shown in Jiri mountain and Donggang area. This implies that both Paleoshoreline angles and valley degradation shifted at at the same rate in Korea. This means that terrestrial uplifting plays an important role on both coastal geomorphic process and valley degradation system. In Korea traditional glacial / interglacial climatic fluvial terrace formation, responding to both extraglacial excessive valley cutting regime and subtropical pedological geomorphic process as end-member, may be deviated by exceptional differential uplift.
