Hydrogen-induced decomposition of fayalite (Fe2SiO4) at high pressure is of considerable interest for a better understanding of the chemical processes occurring in the cores and mantles of icy satellites. At pressures up to 10 GPa and temperatures 25

Thermal stability of fayalite (Fe2SiO4) is studied at hydrogen pressures up to 7.5 GPa and temperatures up to 400 °C. Powder samples of Fe2SiO4 were exposed to a hydrogen or deuterium atmosphere for 24 h in the Toroid-type apparatus at pre-selected

The solubility of hydrogen in amorphous Mg0.6SiO2.6 at a temperature of 250°C and pressures up to 75 kbar is studied using a quenching technique. The molar ratio H2/formula unit is found to nonlinearly increase with pressure from x = 0.12 at P = 10
