Late Quaternary sedimentation in the Kadeok region, Korea

Analyses of high-resolution seismic-reflection data and geological samples revealed the characteristics of Quaternary sedimentation in the Kadeok regi on 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-Pleistocen e 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. Holoc ene mud in the sea to the west of Kadeok Island was transported through a p assway north of the island.
