Figure 40.

Plot of the range of chondrite compositions (from Figure 9) versus martian mantle estimates from shergottite meteorites (Table 2 – MgO-HSE regression method) and high-P and high-T experimental constraints on martian mantle composition (Righter et al. 2015) (× 150). Estimates of martian mantle composition from shergottite meteorites are associated with large uncertainties (error bars). The high-P, high-T estimate of martian mantle HSE content at 14 GPa and 2100 °C does not reproduce chondritic Re/Os. Note linear scale. Orgueil normalization from Table 3.
