Iron isotopic fractionation between silicate mantle and metallic core at high pressure

Iron isotopic fractionation between silicate mantle and metallic core at high pressure

Terrestrial basalts have a unique iron isotopic signature taken as fingerprints of core formation. Here, high pressure studies show that force constants of iron bonds increase with pressure similarly for silicate and metals suggesting interplanetary isotopic variability is not due to core formation.
