Contributions are also invited on applications to new materials, current developments and methodological aspects of ESR, Thermoluminescence and Radioluminescence, and novel Optical Dating techniques such as TT-OSL and PIR-IRSL.The conference will be followed by an optional 3-day field trip that will take participants to the south-east of South Australia for a palaeontological and geological themed visit to the World Heritage Naracoorte Caves fossil sites, the stranded Pleistocene beach ridges and UN Kanawinka Geopark and the world-famous Coonawarra and Limestone Coast wine regions.These techniques can be grouped as numerical, relative dating, and correlation.Numerical techniques are best, but datable materials are often lacking, and in these cases age estimation must be made using relative-dating or correlation techniques.Geologic assessment of active tectonism depends on two key measures: the age and the amount of deformation of a given stratigraphic unit.The amount of deformation can normally be measured with greater accuracy than the age.Oversimplified, the longer something has been buried, the more damage should be found.The extent of damage can be measured with electron spin resonance (ESR), a technique that looks at the unpaired electrons often found when a stable bond is broken.

The Wadi Zewana coastal fan near Tolmeita was studied and a range of dating techniques (U-Th, ESR and OSL) applied to selected components of the stratigraphy.Electron spin resonance (ESR) dating was introduced into archaeology about 20 years ago.Although the method is still in a rapid phase of development, it has demonstrated its value by providing new chronological evidence about the evolution of modern humans.Adequate age control is thus a limiting factor in studies of active tectonism.About 26 dating techniques can be applied to dating deposits and deformation of late Cenozoic age (past few million years).ESR dating in archaeology has been applied to tooth enamel, speleothems, spring deposited travertines, shells and burnt flint.
