Bienvenue au 23e congrès de l’Association Internationale de minéralogie (IMA), qui se tiendra à Lyon, France, du 18 au 22 juillet 2022 (https://www.ima2022.fr/) et où, en particulier, la minéralogie aux couleurs de l’exploration spatiale sera mise en avant. L’IMA a déclaré 2022 Année de la minéralogie. En 2022, nous honorons également le bicentenaire de la mort du plus célèbre minéralogiste français, René Just Haüy. Notez le déroulement d’une session dédiée à l’étude des minéraux terrestres et extraterrestres à l’échelle nanométrique :

Session T9-S2. Nanoscale contributions to terrestrial and extraterrestrial mineralogy

Conveners: Anne-Magali Seydoux-Guillaume (CNRS, LGL-TPE, France) and Lee White (Open University, UK)

Minerals record isotopic and structural evidence that tells us about the nature, intensity or duration of geological processes (including metamorphism, weathering, and deformation). For many systems, the size of minerals and features which preserve evidence of these processes require a challenging sub-micrometer approach. This is made possible by the improvement of new high spatial resolution analytical techniques including Transmission Electron Microscopy, Atom Probe Tomography, STXM, TKD, NanoSIMS, TOF-SIMS, and many others which make it possible to extract chemical, isotopic and structural information at close to atomic scale. This session aims to bring together researchers focusing on the development and integration of “nanoscale” analytical techniques in terrestrial and extraterrestrial minerals to solve major geological and planetary issues.
