Description :
Potassium-rich feldspars separated from aeolian sands from the East and West Cronese Basin have been dated by IRSL. Sands from shoreline-reworked aeolian dune ridges in the West Cronin Basin suggest that Late Holocene playa lakes have existed in the basin within the last 2000 years. 4 dates from these ridges suggest that a phase of aeolian deposition and stabilisation occurred 150-250 years ago. Late Pleistocene dates were obtained from an eolian unit in the East Cronese Basin giving limiting ages on wavecut shorelines formed in the deposit. This aeolian sand appears to have been deposited at a similar time to part of the Cat Dune.
