Fe2+ Partitioning in Al‐Free Pyrolite: Consequences for Seismic Velocities and Heterogeneities

Geophysical Research Letters
Iron partitioning among the main lower mantle phases, bridgmanite (Bm) and ferropericlase (Fp), has non‐monotonic behavior owing to the high‐spin to low‐spin crossover in ferrous iron (Fe2+) in Fp.

Abundant high-pressure minerals and submicroscopic metallic iron discovered in a shocked lunar meteorite

Communications Earth & Environment
Although the Moon’s surface is covered by countless impact craters, high-pressure phases are rare in lunar samples, limiting our understanding of impact history and their associated shock effects.
