Sedimentary framework for the Allendale-Topper Site.
Seventeen cores have been taken in Allendale County, South Carolina adjacent to the Savannah River to reconstruct the fluvial history and establish the stratigraphic framework for the Topper Site in hopes to date the sedimentary section that contains pre-Clovis artifacts. Vibracoring method was used to collect cores from the alluvial plain and eastern bank of the Savannah River. Recovered sediments were collected to steel core pipes. The cores were then split vertically, photographed using digital photo, and described to provide the base for reconstruction of depositional environments and core correlation. Several samples for radiocarbon dating have been taken from the longest cores. The Savannah River Valley does not exhibit one continuous episode of fluvial deposition, but rather a series of cut and fill depositional events. However, the collected cores show reliable correlation between cores and with the Topper Site. Four sedimentary units were distinguished in Turnaround coring site according to sediments lithology and textures, which represent four different depositional environments in studied area. Carbon dating has provided dates of 37,810 yr. BP [+ or -] 570 yr, 34,210 yr.. BP [+ or -] 370yr, 25,330 yr.. BP [+ or -] 130yr and 18,500 yr.. BP from silty clay and sand sections of recovered cores that stratigraphically correspond to the sedimentary section of Topper Site.
