Determination of phase relations of the olivine–ahrensite transition in the Mg2SiO4–Fe2SiO4 system at 1740 K using modern multi-anvil techniques
Chanyshev, Artem; Bondar, Dmitry; Fei, Hongzhan; Purevjav, Narangoo; Ishii, Takayuki; Nishida, Keisuke; Bhat, Shrikant; Farla, Robert; Katsura, Tomoo (Contributions to Mineralogy and Petrology, 2021-09-20)The phase relations of iron-rich olivine and its high-pressure polymorphs are important for planetary science and meteoritics because these minerals are the main constituents of terrestrial mantles and meteorites. The ... -
Oxygen Vacancy Substitution Linked to Ferric Iron in Bridgmanite at 27 GPa
Fei, Hongzhan; Liu, Zhaodong; McCammon, Catherine; Katsura, Tomoo (Geophysical Research Letters, 2020)Ferric iron can be incorporated into the crystal structure of bridgmanite by either oxygen vacancy substitution (MgFeO2.5 component) or charge-coupled substitution (FeFeO3 component) mechanisms. We investigated the ... -
Water Content of the Dehydration Melting Layer in the Topmost Lower Mantle
The water‐rich mantle transition zone and dry lower mantle suggest that a dehydration melting layer can form at the 660‐km depth boundary. However, the water content of the melting layer (CH2Omelt), which dominates its ... -
Water Solubility in Fe‐Bearing Wadsleyite at Mantle Transition Zone Temperatures
Wadsleyite can store significant amounts of H2O in its crystal structure as hydroxyl. However, H2O solubility in Fe‐bearing wadsleyite remains poorly constrained at mantle transition zone temperatures. Previous studies ...
