Pressure Effect on Dislocation Creep Rheology of Lower Mantle Minerals: Importance of In-situ High-Pressure Deformation Experiments Using Synchrotron X-ray Facilities
FROM GRAIN TO EARTH: UNDERSTANDING PLATE TECTONICS THROUGH ROCK MICROPHYSICS AND RECRYSTALLIZATION TO MANTLE-SCALE ANALYSES II POSTER
mineral and rock physics | 13 december 2023
Jennifer Girard, Shun-ichiro Karato
The lower mantle is mostly composed of bridgmanite (~70%) and magnesiowüstite(~20%). Assuming diffusion creep, Yamazaki and Karato[1] suggested a larg...
