  • When such metamorphic fluids have less than 10 % molar proportion of CO 2, reactions favor serpentinisation, resulting in serpentine-amphibole type assemblages.
  • Lost City provides geologists, chemists and biologists a working ecosystem for the study of life and other processes driven by abiotic production of methane and hydrogen by serpentinisation.
  • An example could be the formal comparison of serpentinisation dealing both with the hydration of two structurally similar earth-alkaline silicates, Ca 2 SiO 4 and Mg 2 SiO 4, respectively.
  • The degree to which a mass of ultramafic rock undergoes serpentinisation depends on the starting rock composition and on whether or not fluids transport calcium, magnesium and other elements away during the process.
  • An article on BBC News Science page says there is methane being produced on Mars it says this could be geological in origin or biological, Geological would be Active volcano not heard of this before on Mars 1 . is there known active Volcanoes ? or by a process of Serpentinisation-which is a process involving water . 2 . is water in suffcient quantity to produce this effect would it need to be free flowing or in a solid form Ice maybe ? and last but not least Biological activity which i assume they mean life in some form ?
