| Abstract: | Analyses of high-resolution seismic-reflection data and geological samples revealed the characteristics of Quaternary sedimentation
in the Kadeok region at the opening of the Nakdong River. The sediments comprise two layers, i.e., a 20- to 45-m-thick Holocene
mud layer, and a coarser late-Pleistocene layer deposited in a fluvial environment. Sedimentological variations in the late-Pleistocene
layer to the west and east of Kadeok Island are due to differences in channel maturity prior to the Holocene transgression.
Holocene mud in the sea to the west of Kadeok Island was transported through a passway north of the island.
