This study was carried out geochemically and mineralogically to define how Kunsan shore sediments are related to their terrstrial source rocks in the region of Keum River Basin, western Korea. As a whole the chemical composition for major elements, trace elements and rare earth elements analysis from shore sediments and river bed sediments doesn t show the big difference, and especially rare earth elements chondrite normalized patterns are almost same. Heavy minerals of shore sediments are identified as horn-blende, epidote, ilmenite, garnet, hematite, sphene and rutile. Compared with Taean Area of Seo et al. (1998) and Byeonsan Area of Kwon et al. (1999). Kunsan shore sediments of this study area were origined mostly from Keum River Basin. Key words : shore sediments, riverbed sediments, rare earth elements, chondrite.
