Résumé du projet

PLANEX aims at developing a high pressure high temperature (HP-HT) experimental and analytical platform allowing to perform (1) in situ chemical, structural and isotopic analyses, on fluids (molten silicates and salts, hydrous fluids and gases) and (2) simulation of fluid transfer processes in geomaterials or their synthetic equivalents, with implications in various socio-economic fields, in particular, volcanic risk management, exploitation of geothermal and mineral ressources, the improvement of industrial processes involving silicate or salt melts and related fluids, the geological storage of energy and CO2. To reach this goal it gathers the expertises of 7 laboratories : ISTO (experiments on silicate liquids HP-HT), CEMHTI (HT in situ spectroscopies on silicate liquids and molten salts), LPC2E (gaz spectroscopy, isotopes), GREMI (X-ray flash source), CRPG (isotopic analyses via ion probe), BRGM (simulation of fluid transfers in reactive media), IRCP (molten salts and fuel cells) and I. Néel (transparent vessels). The new instruments consist of (1) a novel Griggs apparatus allow high precision deformation up to 3 Gpa, (2) an upgraded Paterson press devoted to deformation up to 0.3 Gpa, (3) hydrothermal vessels allowing simulation of reactive transfer of fluids in porous media with the monitoring of permeability and fluid chemistry, (4) electrochemical measurements on molten salts/carbonates, (5) one IHPV allowing sampling of fluids coupled to a high resolution laser spectrometer, (6) a Brillouin and Raman spectrometers coupled to a heating stage device for 2D mapping, (7) 3 transparent vessels coupled to IR, Raman and X-Ray spectroscopic devices. In addition PLANEX has upgraded the SIMS national facility and acquired a FEG-MEB, for chemical characterisation of run-products. Phase 1: equipements (1) to (6) are operational, while the transparent vessels (7) are in the final stage of installation. Phase 2 has started on equipements (1) to (4), and SIMS/FEG-MEB
