Optical dating of sediment using optically stimulated luminescence has become important
for studying Earth surface processes, and this technique continues to develop rapidly. A …

Continuing developmental work into optical dating has led to some clarification of the optical
behaviour of quartz and feldspar sediment extracts. We have verified the key assumption …

Single aliquot protocols are now widely used as a means of measuring the equivalent dose
(De) in quartz and feldspar optical stimulated luminescence (OSL) dating of both heated and …

In the last 30 years, from 1967 to 1997, the use of luminescence signals from naturally
occurring minerals has gone though a major metamorphosis, from thermoluminescence (TL) …

Coarse grained quartz has been widely used for optical dating due to its natural abundance,
lack of fading and, as was found by Godfrey-Smith et al (1988), the fact that the quartz OSL …

K-feldspars were exposed to optical stimulation using different wavelengths and the
resulting emissions studied. The existence of a rather deep light-sensitive trap (∼ 2eV) is …

Three exponential components have been isolated from observed high temperature OSL
decay data of quartz. These components have been found to display differential bleaching …

The paper reviews basic spectral features of luminescence from minerals used in dating and
allied research. Luminescence production is a result of multiple interactions within the …

The principles behind a regenerative-dose single-aliquot protocol are outlined. It is shown
for three laboratory-bleached Australian sedimentary quartz samples that the relative …

The date at which people entered Australia has important implications for the debate on
modern human origins. Thermoluminescence dates of 50–60 ka, reported for initial …
