Genetic Stratigraphy And Geochronology Of Last Interglacial Shorelines On The Central Coast Of South Carolina, Russell Willis
Genetic Stratigraphy And Geochronology Of Last Interglacial Shorelines On The Central Coast Of South Carolina, Russell Willis
LSU Master's Theses
This study investigated the shallow subsurface of the Lower Coastal Plain of South Carolina in order to determine the sea-level history and stratigraphic architecture preserved within several emergent shoreline complexes. The absolute age of each shoreline complex was estimated using single-aliquot regenerative-dose (SAR) optically stimulated luminescence (OSL) techniques. The resulting geochronology was incorporated into a high-resolution stratigraphic framework defined by ground penetrating radar calibrated with deep sediment cores, many of which contain a complete sequence of highstand deposition. Three emergent barrier complexes were identified within the Lower Talbot, Pamlico, and Princess Anne terraces, and assigned to sea-level highstands during interglacial …
