L existence d océans aqueux sous les surfaces des grands satellites de glace de Jupiter et Saturne, théorisée durant les années 1970, est aujourd hui confirmée par les données des missions Voyager, Galileo et Cassini-Huygens. La composition des matériaux chondritiques et cométaires et les données des missions spatiales érigent aujourd hui le sulfate de magnésium et le dioxyde de carbone parmi les principaux contaminants pouvant être attendus dans ces océans extra-terrestres. Pour éclaircir les implications de la présence de ces constituants, des expériences ont été menées afin de compléter l'exploration encore partielle des systèmes H2O CO2 et H2O MgSO4 aux conditions de haute pression (0 2 GPa), de basse température (250 350 K) et de compo...
