Abstract
Data on geochemical analysis of sediment cores obtained from Lake Priyadarshini, Schirmacher Range, Eastern Antarctica is presented. Elemental distribution in vertical profiles has been correlated with the redox cycles which provide information about depositional environment. Very low sedimentation rate is inferred in the periglacial environment of Antarctica with a very limited sediment supply. A 14 C age of ~8 kyr indicates that the lake formed in early Holocene as a result of major deglaciation after the end of the last glacial period.
