Esr dating in quaternary geology
ESR dating measures the amount of unpaired electrons in crystalline structures that were previously exposed to natural radiation.
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 dating can be described as trapped charge dating.Radioactivity causes negatively charged electrons to move from a ground state, the valence band, to a higher energy level at the conduction band.Sites I have studied include Olduvai Gorge in Tanzania to look at early human evolution, Iringa in Tanzania to estimate the evolutionary history of our own speices, Mesmaiskaya Cave in Russia where there may have been overlap of modern humans and Neanderthals, and Moendas Cave in Brazil, location of the oldest human skeletal remains in the Western Hemisphere. An exciting application here has been the study of burnt bones from South Africa.Evidence shows that they had to be heated in a campfire.

The term "speleothem" as first introduced by Moore (1952), is derived from the Greek words spēlaion "cave" théma "deposit".
