A Testimony of Detachment of an Inland Lake from Marine Influence during the Mid-Holocene in the Vestfold Hills Region, East Antarctica
A 47 cm long sediment core collected from an inland lake of the Vestfold Hills, East Antarctica has been examined to reconstruct the palaeolacustrine environmental changes. The core shows dates at two core intervals of 18–19 cm and 28–29 cm as 5050 ± 98 yrs BP and 5560 ± 96 yrs BP, respectively. The...
