Oxidized conditions in iron meteorite parent bodies

Abstract:

Magmatic iron meteorites are thought to originate from the cores of differentiated planetary embryos, but it is unclear where they formed in the circumstellar disk. Oxygen fugacity (fO2) is thought to have varied radially across the disk, affecting planetary accretion and core formation. Metal-silicate equilibration experiments show that the chromium concentration in metallic melt increases with decreasing fO2. Chromium can therefore be used to reconstruct fO2during metal segregation. Here, w...
