Pleistocene Shoreline Sediments in Coastal Georgia: Deposition and Modification

Abstract
New evidence invalidates the former concept that Pleistocene shorelines are "terrace" cut and fill structures. Comparison of Pleistocene and Holocene sediments with morphology of the shoreline indicates that Pleistocene deposits accumulated in barrier-island environments and that the "terraces" are former lagoon-salt marshes. Stratigraphic evidence supports six major Pleistocene shorelines below an elevation of 100 feet (30 meters).
