| Abstract | Most of the west coast of Korea is fronted by broad intertidal sand- and mud-flats formed in a macrotidal environment that is seasonally subjected to monsoonal winds and intense winter storm surges. Field studies, conducted in about 60 km2 of Namyang Bay, Korea, were undertaken for the dual purpose of describing tidal flat sedimentary facies (surficial and vertical) and tidal lamination structures (core slabs). Surficial sediments coarsen both seawards (from 7 .3 phi to 4.5 phi) and with depth, resulting in a decrease in fine silt and clay-sized material. Furthermore, the data highlight the environmental significance of primary fine lamination in this high-tide--range intertidal depositional environment. Three types of primary fine lamination can be recognized on the basis of grain-size and lamina thickness. Variability of lamina thickness appears to be related to the spring-neap tidal cyclicity and high-low turbidity variations. |
