The limestone caves of the Naracoorte region in South Australia contain extensive deposits of megafauna-rich sediments and intercalated cave formation (speleothems). High-precision thermal ionisation mass spectrometry (TIMS) U/Th dating of flowstones directly associated with several large deposits reveals a distinct cyclicity in the timing of sediment and flowstone depositional events in the Naracoorte caves. This pattern parallels a cyclical alternation of 'Wet Phases', and intervening periods...[Show more]
