Trapped charge chronometry beyond sediment dating
Trapped charge chronometry beyond sediment dating
Session ID#: 118782
Session 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.
