Notes. Values represent ensemble averages of all qualifying simulation systems, with uncertainties indicating the 1 ±σ dispersion among simulations. Reference compositions for Earth and Mars are also listed for comparison. Mantle compositions are reported as oxides, whereas core compositions are given as elemental abundances. The resulting CMF are also shown.
