Iron Partitioning in Earth's Mantle: Toward a Deep Lower ...

Abstract. We measured the spin state of iron in ferropericlase (Mg 0.83 Fe 0.17)O at high pressure and found a high-spin to low-spin transition occurring in the 60- to 70-gigapascal pressure range, corresponding to depths of 2000 kilometers in Earth's lower mantle.This transition implies that the partition coefficient of iron between ferropericlase and magnesium silicate .
