Apart from one age inversion attributed to recent disturbance associated with mining, the OSL ages are in sequential order when considered in the context of their associated error terms.
The OSL ages indicate an extremely rapid initial phase of sedimentation (i.e.
The age is obtained by measuring the radiation dose received by the sample since it was last bleached by sunlight, and dividing this estimate by the dose rate from environmental sources of ionising radiation.
The new microscopes cater for current research into soil micromorphology and the function of ancient stone, bone and shell tools.
The OSL dating laboratory is also at the forefront of technical advances in the analysis and interpretation of OSL data collected from single sand-sized grains of quartz, building on the pioneering research of Roberts and Jacobs in this field.

Preliminary results of an optically stimulated luminescence dating study in the western Murray Basin in semi-arid south-eastern Australia are presented.
The ultimate objective of the dating study is a reconstruction of dune formation indicative of palaeoclimatic changes in this region.
