...Christopher D.K. Herd Abstract The NWA 1068/1110 martian meteorite contains megacrystic olivine and associated chromite set in a basaltic groundmass of pyroxene, maskelynite (shock-isotropized plagioclase), phosphates, ilmenite, and ulvöspinel. Spinel is compositionally zoned from chromian cores...

.... On the other hand, the more isotopically enriched shergottites such as NWA 1110 and EETA 79001 have early spinel with higher magnetite (3–6%) and inverse spinel components (magnetite + ülvospinel ~ 5–7%). Based on comparison with our data, the f O 2 of crystallization for the enriched shergottites is more...

In comparison, the redox conditions reported by Herd...
