Figure 2: Characterization of the reaction products.
From: Effect of water activity on rates of serpentinization of olivine
(a) Raman spectrum showing characteristic O–H bands of serpentine (lizardite) and brucite, the broad band for liquid H2O and H2 in the vapour bubble. (b) Raman map of the SFI: serpentine shown in red, brucite in green, aqueous solution in blue and H2 in yellow. (c) Reaction products attached to the wall of an SFI imaged after the SFI was excavated by FIB. (d) TEM image of an SFI showing the fibrous and conical shapes of serpentine (chrysotile) crystals.
