Mid-mantle water transportation implied by the electrical and seismic properties of ε-FeOOH
Water in the mantle transition zone and the core-mantle boundary plays a key role in Earth's
stratification, volatile cycling, and core formation. If water transportation is actively running …

Seismological expression of the iron spin crossover in ferropericlase in the Earth's lower mantle
The two most abundant minerals in the Earth's lower mantle are bridgmanite and
ferropericlase. The bulk modulus of ferropericlase (Fp) softens as iron d-electrons transition …
