Depositional Environment in a Fresh Water Lake in Eastern Antarctica Inferred from Shallow Sediment Cores

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...
