Radiocarbon determinations luminescence dating and australian archaeology

We describe a rapid OSL methodology for dating burnt hearth stones to complement previously applied radiocarbon methods, which we have tested using 37 samples from hearths with radiocarbon determinations.We propose a geoarchaeological model in which these hearths were constructed by people whose activity took place on an archaeological surface, formed by the earlier deposition of fluvial sediments.Bioluminescence, fluorescence, and phosphorescence are examples of luminescence that can be produced by biological or chemical processes.Luminescence is a phenomenon occurring in crystal materials, when electrons, trapped in special energy stages (traps) caused by defects in crystal structures, are released and emitting light (luminescence) which wavelength corresponds the change in charge carriers energy stages during the process.Research conducted by the Western New South Wales Archaeology Program (WNSWAP) provides the opportunity to assess the reliability of optically stimulated luminescence (OSL) dating of late Pleistocene and Holocene fluvial sediments and burnt stone samples from arid zone geoarchaeological contexts.

The emission of light that does not derive energy from the temperature of the emitting body, as in phosphorescence, fluorescence, and bioluminescence.

In more extensive dating models the usability of method grows when separate luminescence dating results can be added for example with radiocarbon results and thereby grow up the knowledge behind the models.
