Thermoluminescence chronology of late quaternary deposition on the riverine plain of south-eastern Australia

Journal Article


Abstract


  • Thermoluminescence (TL) datinq of surficial deposits of the Riverine Plain of south-eastern Australia has revealed a record of fluvial, aeolian and lacustrine deposition during the last 100,000 years (100Ka). At the end of the last interglacial the Plain was networked by low sinuosity, bedload-dominated prior streams which declined in activity after about 85Ka. A subsequent phase of prior stream activity in the northern Murrumbidgee region dates at between 50 and 40Ka and corresponds with a period of high lake levels in southern Australia. Local tectonism on the southern part of the plain confuses an interpretation of riverine response to changing Pleistocene climate. TL dates show that drainage diversion in response to tectonic movement along the Cadell Fault near Echuca began as early as 60Ka but that the damming of the Goulburn River to produce Lake Kanyapella did not occur until about 30Ka. Hydrologic changes on the Riverine Plain correlate broadly with those documented elsewhere in Australia, notably in the Lake Eyre Basin and numerous inland playa systems. �� 1991, Taylor & Francis Group, LLC.
