Notes | Authors prefer the OSL dates to the TL dates due to issues with insufficient bleaching. Artefacts per litre begin at 250 cm (>14,300 yrs BP) increasing to a peak (the highest of the whole sequence) at 215-220 cm (between 14,300 and 4,000 yrs BP) followed by a general decline between 215 and 140 cm (approx 2,500 yrs BP) (centred at 150 cm) before increasing again at 120 cm (approx 2,500 yrs BP) and staying continuously high until a significant drop at 15 cm (post contact). These dates need to be compared with OSL/TL dates undertaken as part of this study. In general, the study found unifacial/bifacial points occurred in the sandsheets (open site here) <3680 and >2100 yr BP and before 900 BP in the rockshelters. Sandsheets revealed occupation much earlier than the rockshelters - Goorurarmum sand sheet reveals the lowest artefact and ochre just below 14,300 +/- 400 yr BP (OSL), versus the rockshelter, which shows basal ages of 600 +/ 200 yr BP. In Karlinga, stone artefacts are recovered from the sand sheet at about 19,000 yr BP versus the rockshelter at <4,100 yr BP. |
