Alluvial-channel and overlying eolian deposits exposed in coastal cliffs in the Port Campbell australite (Australian tektite) strewn field, SW Victoria, were studied stratigraphically and dated by optically stimulated luminescence (OSL) for quartz sa

Samples from plutonic geological settings emit strong and stable UV, blue and red luminescence. These samples provide a unique opportunity to investigate the evolution of luminescence emissions by comparing their origin, intensity, trapping and recom

Thermoluminescence (TL), Optically-Stimulated Luminescence (OSL) and Infrared-Stimulated Luminescence (IRSL) emitted from a set of 19 salt (NaCl) samples were studied for potential application to retrospective dosimetry. TL emission spectra revealed

The thermoluminescence (TL) of porcelain is investigated in order to develop better protocols for retrospective dosimetry. Spatial, spectral and kinetic measurements have been made on several electrical insulators. We broaden our search for suitable

Quaternary alluvial sediments occur within and on the flanks of the Mt Lofty Ranges of southern South Australia. Within the ranges they occupy colluvium-filled bedrock depressions, alluvial-fan sequences at hill/plain junctions and river terraces tha

A geochronological framework for the sequential development of coastal barrier aeolianite complexes in the mouth region of the River Murray, Australia's largest river system is presented based on amino acid racemization and thermoluminescence dating.

An unusual shell deposit at Moyjil (Point Ritchie), Warrnambool, in western Victoria, has previously been dated at 67±10 ka and has features suggesting a human origin. If human, the site would be one of Australia’s oldest, justifying a redetermina

Artesian spring mound deposits in the southwestern part of the Great Artesian Basin arise from groundwater discharge from flowing springs in the southern and western margins which reaches the surface through faults and weaknesses in thin confining be

We report single-grain quartz luminescence ages for the Puritjarra rock shelter, with the aim of resolving an apparent discrepancy between ages obtained by 14 C and a variety of luminescence methods, previously reported. Ages now found at all depths

Roonka, the Aboriginal habitation and burial site on the River Murray, South Australia, was excavated from 1968 to 1983. In 1983, thermoluminescence (TL) ages were obtained for several fireplaces at the East Bank site. Sandy dune sediments collected
