| Session Description |
Alkaline (pH 10 – 12) hotsprings in ophiolites are unique in the way that heat is derived from exothermic serpentinization processes and not from a magma-heated reservoir rock. These springs serve as terrestrial analogues for a number of peridotite-hosted deep sea hydrothermal vents. Furthermore, the resemblance of the seafloor crust with areas of Martian crust makes ophiolites a good Mars analogue. Subsequent carbonation of serpentinized ultramafic rocks can also create an environment suitable for carbon sequestration strategies. Interaction of high pH fluids with sediments at the top of the ophiolite sequence have recently been investigated by researchers involved in radioactive waste disposal. We welcome studies from all fields to better elucidate the hydrochemical, geochemical and biogeochemical processes occurring in ophiolites and their impact and applications. |
