Discovery of bridgmanite, the most abundant mineral in Earth, in a shocked meteorite
Meteorites exposed to high pressures and temperatures during impact-induced shock often
contain minerals whose occurrence and stability normally confine them to the deeper …

Depressed 660-km discontinuity caused by akimotoite–bridgmanite transition
The 660-kilometre seismic discontinuity is the boundary between the Earth's lower mantle
and transition zone and is commonly interpreted as being due to the dissociation of …

Lower-mantle water reservoir implied by the extreme stability of a hydrous aluminosilicate
The source rocks for basaltic lavas that form ocean islands are often inferred to have risen
as part of a thermal plume from the lower mantle. These rocks are water-rich compared with …

Buoyancy of slabs and plumes enhanced by curved post-garnet phase boundary
Mantle convection manifests in the subduction of cold slabs and the upwelling of hot plumes,
driving both near-surface processes such as volcanism and seismicity and the chemical …

Metal–silicate partitioning of sulphur, new experimental and thermodynamic constraints on planetary accretion
Partitioning of sulphur between liquid Fe-rich metals and silicates (DS met/sil) was
investigated at temperatures from 1800° C to 2400° C, pressures from 2 to 23 GPa and …
