EP047:
The development and application of chronometers in geomorphology

Submit an Abstract to this Session



Session ID#: 29505

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.
