Activités de recherche (research activities)

Chemistry and isotope chemistry of detrital and authigenic components and of brines of sediments in deposition, diagenetic, low-grade metamorphic and weathering conditions, with a special emphasis on the mechanisms of clay crystallization and recrystallization.

The recent research efforts have been directed towards: (1) the diagenetic evolution of sedimentary basins with a special attention to problems of time, duration and temperature conditions of the events, and (2) the use of combined techniques including chemistry and isotope chemistry of minerals and brines, TEM and SEM observations, fluid inclusion micro-thermometry in order to improve understanding of mineral-brine interactions.
