On the iron isotope composition of Mars and volatile depletion in the terrestrial planets

Sossi, Paolo; Nebel, Oliver; Anand, Mahesh; Poitrasson, Franck


Iron is the most abundant multivalent element in planetary reservoirs, meaning its isotope composition (expressed as δ⁵⁷Fe) may record signatures of processes that occurred during the formation and subsequent differentiation of the terrestrial planets. Chondritic meteorites, putative constituents of the planets and remnants of undifferentiated inner solar system bodies, have δ⁵⁷Fe ≈ 0‰; an isotopic signature shared with the Martian Shergottite–Nakhlite–Chassignite (SNC) suite of meteorites....[Show more]
