The effect of oxygen fugacity on hydroxyl concentrations and speciation in olivine: Implications for water solubility in the upper mantle

Abstract:

The effect of oxygen fugacity on hydroxyl speciation and solubility in San Carlos olivine was investigated in a series of piston cylinder experiments at 2.0 GPa and 1100 and 1300 °C. The presence of enstatite was intended to fix silica activity and experimental fO2 in most runs was regulated by lining the inner walls of the sample-containing Pt capsules with either Fe, Ni or Re foil. Polarised infrared absorbance spectra show that olivine annealed in capsules lined with Fe foil only contain h...
