Abstract

Extreme global climate change in the Late Neogene is well known. In Australia, climate changed from wet conditions in the Late Neogene to the arid conditions that characterize much of the continent today. We constrain the nature and timing of the onset of aridity in southeastern Australia by detailed stratigraphic analysis of palaeo megalake Bungunnia. The demise of the megalake has previously been thought to herald the onset of arid climatic regimes and the sedimentary record of this event has become a proxy-type section for understanding Plio-Pleistocene climate in southern Australia. Our investigations of this sedimentary record reveal regionally extensive and correlatable aeolo-lacustrin..
