Cosmogenic 3he helium age dating

Therefore, it relies on the early measurements of that of atmospheric helium.

The accuracy of the absolute 3He/4He ratios of the atmosphere and other working standards including HESJ is crucial in some applications of helium isotopes, such as tritium-3He dating, surface-exposure age determination based on cosmogenic 3He, and the accurate measurement of the neutron lifetime.

Cosmogenic nuclide evidence for minimal erosion across two subglacial sliding boundaries of the late glacial Fennoscandian ice sheet.

First attempt to combine terrestrial cosmogenic nuclide (10Be) and Schmidt hammer relative-age dating: Strauchon Glacier, Southern Alps, New Zealand. Overall, in-situ produced cosmogenic radionuclide techniques provide a means with which to constrain a wide range of ice-sheet and glacial models over time-scales of a thousand to a few million years.

3, Strasky, Stefan Di Nicola, Luigia Baroni, Carlo Salvatore, Maria Cristina Baur, Heinrich Kubik, Peter W. Surface exposure ages imply multiple low-amplitude Pleistocene variations in East Antarctic Ice Sheet, Ricker Hills, Victoria Land. An interesting new application, currently at the level of theoretical model development, concerns the unraveling of complex exposure and burial histories.
