An increasing number of radiogenic and stable isotopic systems are used in geosciences to obtain quantitative information on the nature, rates and tempo of processes.

Among them are the measure of the time, fundamental to our knowledge of Earth and Planet history and is central to many sub-discipline in geosciences. Beside traditional radiogenic, non-traditional stable isotopes techniques were developed for novel applications, studying both terrestrial and aquatic (including marine) environments dealing with migration in biological systems, food authentication, environmental monitoring, and also for forensics and archaeometry.

This session accommodates recent developments and trends in all domains of isotope research, inviting contributions in geochronology/thermochronology (e.g. U/Pb; 40Ar/39Ar; Re/Os; U-Th/He; FT; 14C) and exposure dating (e.g., 10Be, 36Cl) as well as in the analysis of non-traditional stable isotopes (e.g. Sr, Ca, Cd, Ba, Hg, Pb) in organic and inorganic matrices in the emerging field of ecogeochemistry.

We are specifically welcoming contributions on methodological and experimental developments introducing new analytical approaches or techniques (e.g., mass bias control in stable isotope analysis, instrumental developments, spatially resolved analytical and imaging techniques), with an emphasis on developments in understanding of system behaviour, new concepts for data treatment and numerical modelling, and direct applications to geological and environmental questions.

This session is sponsored by the European Association of Geochemistry.
