A substantial amount of subducted basaltic crusts may exist in the lower mantle. It features
distinct chemical composition from the peridotitic mantle and plays important roles in the …

Water solubility in the dominant lower-mantle bridgmanite phase remains controversial.
Discrepancies between previous results highlight the importance of the growth high-quality …

The chemistry of bridgmanite (Brg), especially the oxidation state of iron, is important for
understanding the physical and chemical properties, as well as putting constraints on the …

The crystal chemistry of ten well‐characterized bridgmanite single‐crystals with Fe and Al
contents ranging from 0 to 0.40 atoms per two‐cation formula units were investigated by …

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 …

The chemistry of bridgmanite is a crucial parameter for understanding the structure and
dynamics of the Earth's lower mantle. Incorporating Al, Fe2+, and Fe3+ into MgSiO3 …

Bridgmanite may contain a large proportion of ferric iron in its crystal structure in the forms of
FeFeO3 and MgFeO2. 5 components. We investigated the pressure dependence of FeFeO3 …

A series of high-pressure multi-anvil experiments were conducted in the MgO-Al 2 O 3
system between 15 and 50 GPa and at temperatures up to 2623 K, to determine the …

Experimental studies of melting relations in the MgSiO 3–Na 2 CO 3 (±Al 2 O 3, Fe 2 O 3)
multicomponent alkaline carbonate–silicate system were carried out at 23–24 GPa and …

Trivalent cations such as Al 3+ and Fe 3+ can be incorporated into the crystal structure of
bridgmanite either by the charge-coupled mechanism forming the FeFeO 3, AlAlO 3, and …
