The Nakdong River Delta in Korea consists of wide and thick sediments, which are excellent for undertaking highresolution investigations of paleo-environmental evolution. This study describes the horizontal evolution of the sediment environment during the Late Quaternary based on the KND-3 and ND-3 cores obtained from the downstream area of the Nakdong River Delta. The lowest sediments in these cores differ markedly, with KND-3 mainly being composed of olive gray coarse, sandy sediments with pebbles of c. 2-cm diameter, which are interpreted as representing a paleo-channel environment, and ND-3 mainly consisting of red silty sediments (paleosol), which are interpreted as representing alluvial deposits that were exposed to the atmosphere. By contrast, the upper sediments above 40.00 m in both cores were deposited when the sea level rose to a similar level as seen today, at which time both cores evolved through a succession of environments from estuary complex, through to shallow-marine, prodelta, delta front, and the present-day delta plain.
