My work focuses on the interface between chemistry and two other disciplines, geology and archaeology or paleoanthropology.A relatively new way of determining the age of materials is to look at radiation damage caused by radioisotopes in the material itself and in its surroundings.Aggradation phases dated to 76 ± 4 ka, 42.1 ± 5.1 ka and 12.5 ± 1.5 ka are broadly coincident with global glacials and stadials, whilst during the Last Interglacial and successive interstadials the drainage system underwent entrenchment, manifested on the coastal plain as telescopic fan segmentation and associated fan head trenching.
Geologic studies of active tectonism are greatly aided by definition and time calibration of local stratigraphic sequences.
Because all dating techniques may be subject to considerable error, reliability should be assessed by stratigraphic consistency between results of different dating methods or of the same method.
Quaternary geochronology is the field devoted to dating Earth's history of the past 1.8 million years, the Quaternary Period.
The field has come a long way since its early formulations at the beginning of the 20th century and the advent of radiocarbon dating 50 years ago.
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.Including non-dating applications of luminescence and ESR (APLED-4) Nov 22nd, 2015, Dosi Vox Workshop (optional)Nov 23rd-25th, 2015, Conference, Adelaide, Australia Nov 26-28th, 2015, Field Trip, Naracoorte, South Australia The Braggs Building School of Physical Sciences & Institute for Photonics and Advanced Sensing University of Adelaide, Adelaide, South Australia, 5005, Australia The conference seeks to bring together researchers to present new developments in Luminescence and ESR, with particular focus on techniques, applications and issues relevant to the Asia-Pacific region.Luminescence dating has its roots in the middle of the 20th century, with the landmark paper by Farrington Daniels and colleagues (Science, 1953) being the first to expound the application of Thermoluminescence as a dating technique for the geosciences and archaeology.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.The coastal alluvial fan sequences of Cyrenaica are important archives of environmental change data, but hitherto relatively little has been known about their formative processes and rates.
