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)-
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...
