Dating and Rating Landscape Evolution with Geochemical Methods on Geomorphic to Geologic Time Scales

The Earth's surface is under constant change. Tectonic, climatic, biogenic and anthropogenic forcings have a measurable impact on erosion, weathering and surface uplift. Information on the interactions among these processes and their spatio-temporal distribution can be inferred from observations of the available geologic archives. These involve, among others, the morphology and the geochemical-mineralogical composition of exposed bedrock, sedimentary products and soils. In order to successfully predict future landscape responses, it is therefore important to investigate these archives and to quantify the timing and rate of past landscape changes in response to the different forcings. In this session, we gather contributions involving state-of-the-art applications of geochronologic, thermochronologic and geochemical methods, aiming to quantify dates and rates of landscape change. In particular, we welcome any field-, laboratory- and/or modeling-based study, covering a range of timescales (hundreds to millions years), spatial scales (hillslope, catchment, orogen) and techniques (e.g. cosmogenic nuclides, thermochronology, luminescence, isotopic dating etc...).
