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

Abstract 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. Previously reported iron partitioning coefficient between these phases, KD, still have consid...
