Oxygen thermobarometry measurements on spinel peridotite rocks indicate that the oxygen
fugacity at the top of the upper mantle falls within±2 log units of the fayalite-magnetite-quartz …

We have critically reviewed and discussed currently available information regarding the spin
and valence states of iron in lower mantle minerals and the associated effects of the spin …

Meteorites exposed to high pressures and temperatures during impact-induced shock often
contain minerals whose occurrence and stability normally confine them to the deeper …

Phase relations, mineral chemistry, and density of a natural mid-oceanic ridge basalt
(MORB) composition were investigated up to 134 GPa and 2300 K by a combination of in …

Phase transitions and the chemical composition of minerals in Earth's interior influence
geophysical interpretations of its deep structure and dynamics. A pressure-induced spin …

Iron in the major lower mantle (LM) minerals undergoes a high spin (HS) to low spin (LS)
transition at relevant pressures (23–135 GPa). Previous failures of standard first principles …

The global water cycle in the Earth is one of the most important issues in geodynamics,
because water can affect the physical and rheological properties of the mantle. However, it …

Crystallization in Earth's deep magma ocean could have caused trace element fractionation
in the lower mantle that might be inherited to the isotopic compositions of the present-day …

The sound velocities of (Mg. 16Fe. 84) O have been measured to 121 GPa at ambient
temperature using nuclear resonant inelastic x‐ray scattering. The effect of electronic …

Mineral properties in Earth's lower mantle are affected by iron electronic states, but
representative pressures and temperatures have not yet been probed. Spin states of iron in …
