Understanding and quantifying processes that modify and shape the Earth surface requires the determination of accurate dates and rates. Improvement of existing and development of new geochronological methods is essential for a better understanding of those complex, often multiphase processes and their relation to tectonics and climate. Analytical methods range from dating high temperature events by U-Pb in zircon, Ar-Ar in feldspar or Lu/Hf in garnet-mineral assemblages, to exposure and burial dating using cosmogenic nuclides. To mentioning are also recent developments for in situ dating of micas by Rb/Sr and of low-uranium phases, such as carbonates, fluoride and sulfate by U-Pb, which will have a large impact on deciphering medium to low temperature processes.

Thus, this session invites contributions on developments and applications of all dating methods relevant to decipher processes in earth history. Applications that integrate field observation, petrology, and geochemistry with geochronology are also welcome.
