In this session, we propose to explore the parameter time, in all its diversity. Increasingly specific geochronological and thermochronological methods capture the timing of an increasing diversity of tectonic, metamorphic and geomorphologic processes, taking place from Hadean to Holocene, at sub-mineral to orogen scale, in minutes to million years periods, in high-temperature to low-temperature conditions. Geomorphology and tectonics need innovative quantification methods to better reconstruct erosion histories, as well as landscape and structural changes though time. Concomitantly, the volume of geochronological data is exploding, leading to new statistical treatment of information. We invite a discussion on the unprecedented perspectives of geochronology and thermochronology, covering both: (i) new experimental advances on the dating tools and computational tools for data interpretation, and (ii) natural case studies that took advantage of these methodological improvements.
