Past and present fluids in granitic and clayey formations
Fluides passés et actuels dans les formations granitiques et argileuses
Résumé
To characterize chemistry and movement of water in geological formations chosen for their very low water content is somehow paradoxical. We expose the genesis of a predictive model for water-rock interactions applicable to crystalline or sedimentary media. Elemental transfers are described and specific experimental methods developed for these media are cited.
