[1] Infrared spectroscopy on synthetic olivines has established that there are at least four different mechanisms by which hydrogen is incorporated into the crystal structure. Two mechanisms occur in the system MgO-SiO2-H2O associated with silicon and magnesium vacancies, respectively. A third mechanism is associated with trivalent cation substitution, commonly Fe in natural olivine, while the fourth mechanism, which is the one most prevalent in natural olivines from the spinel-peridotite… CONTINUE READING
