| الوصف: | Archaeological excavations in sediments dating to between 60000 and 40000 years ago are rare in Australia. Yet this is precisely the period in which most archaeologists consider that Aboriginal people arrived on the continent. In the few cases where such early sites have been investigated, questions have invariably been raised as to the reliability of stratigraphic associations between cultural items and the surrounding sediments. This paper describes a method for examining sediment mixing in a stratigraphic sequence using the optically stimulated luminescence (OSL) signals from individual sand-sized grains of quartz. We apply this method to the archaeological site of Nonda Rock (north Queensland), in combination with radiocarbon dating of charcoal fragments, to construct chronologies for human occupation and for the preceding, culturally sterile, deposits. Our age estimates have implications for the timing of first human arrival in Australia. Copyright (c) 2007 John Wiley & Sons, Ltd. |
