Dating stone arrangements using optically stimulated luminescence and fallout radionuclides
Buildings and monuments constructed from stone provide some of the best‐preserved surface archaeology, but their construction ages can be difficult to determine using radiocarbon techniques. In Australia, stone arrangements are recognised as architectural or symbolic features belonging to Aboriginal societies. The structures are predominantly inorganic with shallow infill, hampering attempts to determine their antiquity. Optically stimulated lumi…

Holocene lake-level fluctuations in Lakes Keilambete and Gnotuk, southwestern Victoria, Australia
Reconstructed Holocene lake-level curves from two saline, hydrologically closed maar crater lakes in southwestern Victoria, Australia, show near synchronous lake-level changes throughout the Holocene. We show that lake levels, reconstructed from sediment particle size and ostracod valve chemistry (δ 18 O and Sr/Ca) have undergone rapid ( 10 m) fluctuations throughout the Holocene. Finer sampling resolution shows a more sensitive response to Holoc…
Holocene lake salinity changes in the Wimmera, southeastern Australia, provide evidence for millennial-scale climate variability
Palaeosalinity records for groundwater-influenced lakes in the southwest Murray Basin were constructed from an ostracod-based, weighted-averaging transfer function, supplemented with evidence from Campylodiscus clypeus (diatom), charophyte oogonia, Coxiella striata (gastropod), Elphidium sp. (foraminifera), Daphniopsis sp. ephippia (Cladocera), and brine shrimp ( Parartemia zietziana ) faecal pellets, the δ 18 O of ostracods, and > 130 μm quartz …
Optical dating of Holocene sediments from a variety of geomorphic settings using single grains of quartz
New Ages for the Last Australian Megafauna
All Australian land mammals, reptiles, and birds weighing more than 100 kilograms, and six of the seven genera with a body mass of 45 to 100 kilograms, perished in the late Quaternary. The timing and causes of these extinctions remain uncertain. We report burial ages for megafauna from 28 sites and infer extinction across the continent around 46,400 years ago (95% confidence interval, 51,200 to 39,800 years ago). Our results rule out extreme arid…
Distinguishing dose populations in sediment mixtures
Optical Dating of Single and Multiple Grains of Quartz From Jinmium Rock Shelter, Northern Australia
Quartz sediments from the floor deposit at Jinmium rock shelter have been investigated using the multiple‐grain and single‐grain optical dating methods described by Galbraith et al. (1999, this volume). Here we present the results of this dating programme and argue that the artefact‐bearing sediments were deposited within the last 10000 years. This time interval is consistent with the radiocarbon chronology but is much younger than previous claim…
Optical Dating of Single and Multiple Grains of Quartz From Jinmium Rock Shelter, Northern Australia
Jinmium rock shelter is famous for the claims made by Fullagar et al. (1996) for the early human colonization and ancient rock art of northern Australia. These claims were based on thermo‐luminescence ages obtained for the artefact‐bearing quartz sediments that form the floor deposit at the site. In this paper, we outline the background to the optical dating programme at Jinmium, and describe the experimental design and statistical methods used t…

Preliminary luminescence dates for archaeological sediments on the Nullarbor Plain, South Australia
Human occupation of the Nullarbor Plain in South Australia has been known to extend into the Pleistocene since a series of major archaeological excavations was begun in the 1950s and 1960s. An antiquity of more than 20,000 years BP for human presence in the region was established on the basis of 14 C chronologies at Koonalda Cave and Allen's Cave (also known as site N145). The oldest date reported for traces of human activity was -22,000 years BP…
