The FeO concentration of the mantles of Earth, Mars, Vesta and the angrite parent body (APB) plotted as a function of their μ96Zr values. The FeO estimates are from ref. 75. (Earth and Mars), refs. 76,77.(Vesta) and ref. 78 (APB). Uncertainties reflect the internal precision of the measurements (2SE). BSE bulk silicate Earth, BSM bulk silicate Mars.
