Coastal dunes, which hold significant scenic, geological, and ecological value, are now experiencing substantial reductions in extent due to recent human activities. This review summarizes current research on the geomorphological characteristics and formation ages of modern coastal dunes in Korea, as well as the depositional ages and environments of paleodune deposits, and suggests future research directions. In Korea, most studies have been concentrated along the west coast, focusing on long-term coastal geomorphic changes and the physical factors controlling coastal dune formation. Recent advances in optically stimulated luminescence (OSL) dating techniques have enabled comprehensive investigations into the history of dune formation, providing greater precision in understanding their developmental timelines. Concurrently, paleodune deposits underlying modern coastal dunes are readily identifiable by their distinctive reddish coloration and consolidated texture. While the formation ages and depositional environments of these paleodune deposits have been examined, such studies remain relatively scarce. To date, most research has focused on the coastal regions of Chungcheong Province, with recent efforts extending into the Jeolla Province and adjacent island areas. However, paleodune studies in Korea have predominantly focused on determining depositional ages, often using these deposits as proxies for sea-level changes or shoreline migration rather than considering them as independent geological records. With growing geomorphological and ecological interest in coastal dunes, there is a need to expand geological investigations of paleodune deposits in conjunction with other related coastal sediments.
