Recent advances made by reaction experiments on melting of heavily metasomatized hydrous mantle
Mantle-derived magmas are traditionally assumed to originate by melting of an upper mantle
consisting of uniform spinel-or garnet peridotite dominated by olivine. However, extensive …

The role of redox on bridgmanite crystal chemistry and calcium speciation in the lower mantle
The amount of ferric iron Fe3+ in the lower mantle is largely unknown and may be
influenced by the disproportionation reaction of ferrous iron Fe2+ into metallic Fe and Fe3+ …
