  Information - GM21 New applications of terrestrial cosmogenic nuclides in Earth surface science (co-listed in IG)

Event Information
Terrestrial cosmogenic nuclides (TCN) provide quantitative constraints on the evolution of Earth's surface. The last decade has seen an explosion in the use of the workhorse nuclides, 10Be and 26Al, to disciplines such as glacial chronology. This has gone hand-in-hand with the refinement of analysis/interpretation of hitherto less commonly-used isotopes, 3He, 21Ne and 36Cl, and the development of new isotopes, e.g. 14C and 53Mn. These developments offer opportunities for more sophisticated and ambitious applications which are driving development of more complex interpretive strategies and models. The resultant range of quantitative constraints on near surface earth processes now extends well beyond the exposure age‚ versus steady state erosion rate‚ options. This session seeks to tap into these recent developments to provide a flavour of the new applications of TCN. We particularly encourage presentations that integrate chronometers, and/or cover new developments; such as testing concepts on catchment-scale processes and soil processes, constrain long-term landscape development, and paleoaltimetry, to name but a few. This session is co-sponsored by CRONUS-EU.
