  • AGU session on the development and application of chronometers in geomorphology

    Sarah Boulton and colleagues will convene an interesting session at the AGU Fall Meeting. They collect contributions on the development and application of geochronometres, techniques that most of us use in everyday life for dating landscape changes and fault activity. EP047: The development and application of chronometers in geomorphology.

    Session Description

    Isotopes and other quantitative tracers are widely used to quantify rates of geomorphic processes and to fingerprint sediment sources and sinks. However, these techniques, including short-lived fallout radionuclides, cosmogenic radionuclides, optically stimulated luminescence, and thermochronology, all have methodological assumptions that limit their usefulness in geomorphology. This session invites studies using geochemical methods to investigate the rates and progress of landscape change with a particular focus on geomorphic response to perturbations such as environmental change, anthropogenic impact, and tectonic drivers. We also welcome studies that consider new developments in geochronologic techniques or test the limitations and assumptions behind commonly employed methods.
    Primary Convener:  Sarah J Boulton, Plymouth University, Plymouth, PL4, United Kingdom
    Conveners:  Amanda C Henck Schmidt, Oberlin College, Oberlin, OH, United States, Paul R Bierman, University of Vermont, Burlington, VT, United States and Kevin P Norton, Victoria University of Wellington, Wellington, New Zealand
