Luminescence dating in archaeology from origins to optical

more Recent archaeological investigation at Box Gully, located on the north western tip of the Lake Tyrrell lunette, has resulted in the first documentation of pre-30,000 cal BP Aboriginal occupation of the extensive area between the Murray River and the Tasmanian highlands.The remains of repeated small scale camping episodes were uncovered in a palaeosol capping a buried pelletal clay lunette.Review of the late Pleistocene archaeological record of the western Murray Basin allows the finds at Box Gully to be placed in a human occupation context of adaptation to severe climatic stress leading to the Last Glacial Maximum. 27,000 cal BP, lacustrine localities including the Willandra Lakes, Lake Tandou and the Lower Darling were much less heavily frequented than previously, or like Lake Tyrrell, abandoned.At the same time sustained occupation of the Murray River valley occurred, as did the initial occupation of rockshelters in the highlands of southern Victoria.

L'os calciné survit bien en sol acide et donne des informations fiables, précises et très exactes au niveau des âges estimés.Following final lake retreat c.15 ka avulsion of the dominant fluvial inflow eastwards, the Willandra lunettes periodically reactivated, experiencing erosion, aeolian redeposition and alluvial sheetwash.These reworked sedimentary archives reflect regional climatic conditions rather than those of the entire catchment.Des telles pratiques permettront une meilleure démarcation et fournir des explications quant aux taux de changements économiques selon le lieu et la région.Recent archaeological investigation at Box Gully, located on the north western tip of the Lake Tyrrell lunette, has resulted in the first documentation of pre-30,000 cal BP Aboriginal occupation of the extensive area between the Murray...
