Extended Data Fig. 8: Influence of light elements on the density and velocity jumps across the ICB assuming an O-enriched Martian core.

From: Seismic detection of a 600-km solid inner core in Mars

Extended Data Fig. 8

a, From top to bottom: amount of O, C, and S in the Martian core used in our modelling; influence of O content on the density and velocity jumps across the inner and outer core boundary. The amount of O, C, and S and their partitioning between outer and inner core are from ref. 21. b, Calculated density and velocity of Fe-light element alloys in the Martian IC. Grey lines: seismic observations in this study (Case 8); green: Fe; blue: Fe3C; red: FeO.
