      Chanyshev, ArtemORCIDiD; Bondar, Dmitry; Fei, HongzhanORCIDiD; Purevjav, Narangoo; Ishii, TakayukiORCIDiD; Nishida, Keisuke; Bhat, Shrikant; Farla, Robert; Katsura, TomooORCIDiD (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 ...

      Penetrating, high‐energy synchrotron X‐rays are in strong demand, particularly for high‐pressure research in physics, chemistry and geosciences, and for ...

    • Stability and Solubility of the FeAlO3 Component in Bridgmanite at Uppermost Lower Mantle Conditions 

      Liu, ZhaodongORCIDiD; McCammon, CatherineORCIDiD; Wang, Biao; Dubrovinsky, Leonid; Ishii, TakayukiORCIDiD; Bondar, Dmitry; Nakajima, Ayano; Tange, YoshinoriORCIDiD; Higo, YujiORCIDiD; Cui, Tian; Liu, Bingbing; Katsura, TomooORCIDiD (Journal of Geophysical Research: Solid Earth, 2020)
      We report the stability and solubility of the FeAlO3 component in bridgmanite based on phase relations in the system MgSiO3-FeAlO3 at 27 GPa and 2000 K using a multi-anvil apparatus combined with in situ synchrotron X-ray ...
