GIN (Géochimie des Isotopes stables non-traditionnels)

Salle ICPMS

Research on the geochemistry of non-traditional stable itosopes at OMP has shown that these "new" isotopes, inscreasingly scrutinized by international science since around 2000, provide a novel insight into a number of major scientific questions.

OMP teams have thus made discoveries on core formation in telluric planets, metal adsorption on the membranes of micro-organisms, the cycle of pollutants in the environment, the differentiation of silicic magmas, volcanic degassing, or the origin and cycle of iron in the ocean. This research action uses the ICP-MS service and unites the GET, LEGOS, EcoLab, IRAP and LA laboratories. Funding is granted by OMP, CNRS, IRD, UPS, the EU, and ANR.

Our ongoing research endeavors rely on these new skills as well as preexisting competences of the Toulouse community. Topics include mass-independant fractionation of mercury isotopes in atmospheric aerosols of urban and industrial origin; experimental research on cinetic and equilibrium fractionation of magnesium, sicilium and iron isotopes between minerals and continental water; and the stellar nucleosynthesis of iron and nickel isotopes.
