Esr dating in quaternary geology
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.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.

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.
The intervening years have seen the introduction of ESR and Optical Dating, and their rapid evolution and application to diverse fields in which ionising radiation effects provide either a "clock" or a characterisation tool.
The conference invites contributions from this broad range of applications, including Quaternary geology, geomorphology and landscape evolution, palaeontology, palaeobotany, archaeology, soil science, palaeoclimatology, provenancing, mineral prospecting, tectonics, space science, dose-rate assessment, retrospective population dosimetry and radiological event studies, including relating to the aftermath of the 2011 Tohoku earthquake.
Electron spin resonance (ESR) dating was introduced into archaeology about 20 years ago.
