Abstract
Sedimentological, geochemical, geophysical and micropaleontological analyses of 10 borehole cores were carried out to understand depositional environment and sequence stratigraphy of late Quaternary sedimentation in the estuary of the Nakdong River. Holocene Formation in study area is classified into five sedimentary units. Early Holocene freshwater lower pebbly sandy deposit(Unit I), lower muddy deposit(Unit II), middle thin sandy deposit(Unit III), upper muddy deposit(Unit VI), and upper sandy deposit(Unit V), in ascending order contolled by global sea-level change since interglacial period(about 15,000 yrs B.P.). Unit I deposited in erosional environments before marine trangression. Unit II and Unit VI composed of clay were deposited in cold and worm currents for marine trangression., respectively.
