Earth and Planetary Surface Processes

Dear Colleagues,

We kindly invite you to submit your abstracts to the session "Trapped charge chronometry beyond sediment dating" which focuses on recent developments in luminescence and ESR techniques at the AGU Fall Meeting, New Orleans, USA (& Online Everywhere) from December 13 to 17^th.

Recent advances in trapped charged chronometry have given rise to a new generation of luminescence and ESR techniques for quantifying Earth surface processes over unprecedented spatial and temporal scales. This session aims to provide a dedicated forum for the presentation and discussion of the latest research on these new techniques and their novel applications, by bringing the developers and the users of trapped charge chronometry together. Contributions on methodological aspects of the luminescence and ESR techniques, as well as their applications to address complex issues in Earth sciences and archaeology are all welcome.

Session ID: 829527
Title: EP042- Trapped charge chronometry beyond sediment dating
Description: Luminescence burial dating of silt and sand grains has contributed significantly to our current understanding of past climate, landscape evolution and human migration across timescales of years to ~0.5 Ma. Over the past decade, luminescence techniques (TL, OSL, IRSL) along with electron spin resonance (ESR) of quartz have witnessed significant advances both in theory and methodology extending their application beyond sediment dating to thermo- and photochronometry and sediment tracing. Successful case studies have demonstrated the great potential of these techniques in exposure dating, sediment tracing and provenance fingerprinting, besides quantifying erosion, exhumation and sediment transport rates over unprecedented centennial to millennial timescales and millimetre to catchment-size spatial scales. This session provides a platform for discussion on all these rapid developments. We welcome contributions on: i) novel applications, ii) kinetic models for quantifying geomorphic process rates, iii) uncertainty estimation and analyses, and iv) new developments in methodology and instrumentation.
