  • Metastable Phase Relations in the Mantle Transition Region
    NISHI Masayuki, Review of High Pressure Science and Technology/Koatsuryoku No Kagaku To Gijutsu, 24, (2) 136 - 144,   2014 01 01 , Untransformed metastable minerals exist under the low-temperature conditions of the subducting plates. Here I report the experimental studies on the transformation kinetics of pyroxene and garnet at high-pressure and hightemperature conditions. Slow kinetics of the pyroxene-garnet transformation due to the low atomic diffusion rate indicates that large low-density metastable regions would exist in the slab, greatly contributing to the slab stagnation around the mantle transition region.
  • Diffusion Controlled Reaction Rim Growth and Metastable Transformation of Minerals in the Lower Mantle
    NISHI Masayuki, Review of High Pressure Science and Technology/Koatsuryoku No Kagaku To Gijutsu, 25, (2) 172 - 180,   2015 01 01 , © 2015 Japan Society of High Pressure Science and Technology. All rights reserved. Atomic diffusion rates and transformation mechanims of mantle minelars provide important constraints for understanding many physical and chemical processes in the Earth's interior, including mantle rheology and chemical transportation. Here I introduce two recent experimental studies on the atomic diŠusivity and transformation mechanisms of mantle minerals under lower mantle conditions up to 50 GPa using a Kawai-type high-pressure apparatus combined with sintered diamond anvils. DiŠusion-controlled growth kinetics of the polycrystalline MgSiO3 bridgmanite enabled us to estimate the grain boundary diŠusivity of bridgmanite in the lower mantle. Also, metastability of the deep subducted plate was disscussed based on the mechanism changes through the post-garnet transformation under large over pressure conditions.
