Radiocarbon dates of fossil shells from raised beach sediments along the Soya Coast, East Antarctica -A report on a geomorphological survey during JARE-35 (1993-94)-

Abstract

40 Radiocarbon ages are obtained from fossil shells collected from raised beach deposits along the Soya Coast, East Antarctica during the summer season of JARE-35,1994. They are clearly classified into younger Holocene dates of 3ka to 8ka and dates older than 35ka. The older dates are restricted to shells from the Ongul Islands, while the younger ones were found in all outcropped areas, although older dates had been reported from Langhovde in previous studies. Older shells in the Ongul Islands are distributed at higher elevation up to 20m above present sea level than younger shells. The highest elevation of a Holocene raised beach attains 26m above sea level in Skarvsnes. This is the first report of radiocarbon dates from Skallevikhalsen and Rundvagshetta.
