Fe isotope fractionation in iron meteorites: New insights into metal-sulphide segregation and planetary accretion

Abstract:

Magmatic iron meteorites are considered to be remnants of the metallic cores of differentiated asteroids, and may be used as analogues of planetary core formation. The Fe isotope compositions (δ 57/54Fe) of metal fractions separated from magmatic and non-magmatic iron meteorites span a total range of 0.39‰, with the δ 57/54Fe values of metal fractions separated from the IIAB irons (δ 57/54Fe 0.12 to 0.32‰) being significa...
