This video shows the fayalite (ferrous orthosilicate Fe2SiO4)-water interface from a molecular dynamics simulation with a water model capable of breaking up into OH- and H+ ions. This is in the early stages of hydroxylation, representing about 0.25 nanoseconds of real time.
Silicons are blue, oxygens are red, protons are white and irons are brown. Solvent waters are rendered partially transparent. Note that waters in the hydration layer are becoming incorporated into the olivine.
