[1] The concentration and incorporation mechanisms of hydrogen into (Mg, Fe)2SiO4 olivine have been studied under water saturated conditions at 12.5–14.0 GPa and 1100–2000°C. The hydrogen content of olivine (Fo90–Fo95) coexisting with enstatite and hydrous melt increases from about 4600 ppmw at 1100°C to a maximum of 6250 ppmw at 1200°C. Above 1400°C, the hydrogen content of olivine decreases non-linearly, reaching 160–240 ppmw in the 1800–2000°C range where there is a high melt fraction and no… CONTINUE READING
