6000 years of environmental changes recorded in Blue Lake, South Australia, based on ostracod ecology and valve chemistry

Gouramanis, Christos; Wilkins, Daniel; De Deckker, Patrick

Description

A 4m long core taken from the freshwater Blue Lake crater near the township of Mount Gambier in southeastern South Australia provided a high-resolution palaeoclimatic record for the last six millennia. Accelerator Mass Spectrometry (AMS) radiocarbon (14C) dates were obtained from organic plant fibres and biogenic carbonates from the laminated sequence of the core and from a modern water sample. Large discrepancies between the radiocarbon ages determined from plant fibres and biogenic carbonates...[Show more]
