Esr dating in quaternary geology

The reasons for seismic activity in this region can be related to neotectonic movements (including glacio-isostatic rebound) as recorded in the southeastern Baltic Sea area of the Fennoscandian ice sheet margin zone. A preliminary estimation of the time interval for the seismic event covers the period from the early up to the late Holocene. 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.

ESR allows some materials to be dated because free radical concentration is a measurement of the total radiation dose absorbed by the sample during the time it was exposed to radiation and hence their burial time (Jonas 1977).

The relation between a palaeoseismic event and the essential changes in the hydrographic network in the region is also discussed. ESR spectroscopy is the only method for detecting, identifying and quantifying free radicals (Halliwell & Gutteridge 2007; Punchard & Kelly 1996). For instance, this method is used for estimating the free radical level and paramagnetic centres produced in some materials by ionising radiation.
