Abstract

A review is presented of processes controlling sediment alteration and mass transport during hydrothermal seawater-sediment interaction at a constant temperature and pressure and under the influence of a thermal gradient. The results of two thermal gradient experiments involving seawater and sediment are discussed. These experiments were carried out in order to assess the degree and rate of separation of aqueous components in an appropriate thermal gradient. Several areas for future research are outlined. These include additional experiments to determine the temperature and pressure dependence of Soret coefficients for pertinent aqueous species, as well as computer modelling of complex alteration processes involving seawater-sediment interaction at elevated temperatures and pressures.
