Earth’s landscape evolution through time is generated by complex feedbacks between deep (e.g. mantle dynamics, subduction/collision cycles) and surface processes (erosion, weathering, sedimentation). Rates quantification of these processes relies mainly on the measurement accuracy and correct interpretation of geochronological data, including radiogenic dating of mineral crystallisation, low-temperature thermochronology and nuclide cosmogenic dating. Advances in geochronological methodologies are providing significant improvements in analytical precision and resolution, as well as in the volume of available data. At the same time, scientists are realizing that cross-method integration is essential to contextualize dates with geological events.
In this session, we propose to explore the timescale of geological processes that shape the Earth’s landscape based on recent improvements in the geochronological techniques, data treatments or original applications to natural cases. Integrated studies, combining several dating techniques or interdisciplinary methods (e.g. experiments, petrology/geochemistry, computional tools), are particularly welcome.
