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 ... -
Serpentinization-driven H2 production from continental break-up to mid-ocean ridge spreading: unexpected high rates at the West Iberia margin
Albers, Elmar; Bach, Wolfgang; Pérez-Gussinyé, Marta; McCammon, Catherine
; Frederichs, Thomas (2021)
Molecular hydrogen (H2) released during serpentinization of mantle rocks is one of the main fuels for chemosynthetic life. Processes of H2 production at slow-spreading mid-ocean ridges (MORs) have received much attention ... -

(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 ...
