ABSTRACT

Many studies have been carried for a long time about formation timing of the marine terrace in Korea. However, there has been much debate on the age and characteristics of the deposit. In this study, we summarized and analyzed published OSL (Optically Stimulated Luminescence) ages to understand the age of the marine terrace in Korea. Previously published OSL ages differed from real timing of marine terrace formation due to problems such as characteristic of sediment for OSL sampling, type of applied OSL technique, selection of sample not related to marine terrace deposit. It is necessary to exclude abnormal ages considering characteristic of sediment and applied OSL technique to define accurate and precise the age of the marine terrace. Furthermore, researcher’s geomorphological and sedimentological interpretation at the field is important to obtain reliable age result.
