FURTHER THERMOLUMINESCENCE DATES FROM THE DUNE SEQUENCE IN THE SOUTHEAST OF SOUTH AUSTRALIA

Our thermoluminescence dating technique has been applied to several new samples from the remarkable sequence of stranded beach dunes in southeast South Australia that were formed during the past 800 ka. We show that Robe III is probably 100 ka as suggested by Schwebel and not 80 ka as we suggested earlier. A sample from the West Dairy dune is shown to belong to delta(18)O Stage 7 in accordance with Schwebel's original suggestion and not Stage 5 as he suggested later. A new West Naracoorte sample yielded acceptable data and an age consistent with formation just after the Brunhes-Matuyama magnetic reversal at 780 ka as required by palaeomagnetic measurements. Two more samples from the Woakwine dune show that our reproducibility is consistent with our derived errors.
