Fig. 8. Schematic depiction of the final stages of core formation on Mars and Earth and subsequent late accretion. Sulfur, Se and Te in the mantle of Earth and Mars in combination with approximately chondritic HSE ratios require late accretion of volatile element-depleted and -undepleted material onto Mars (this work) and Earth (Wang and Becker, 2013), respectively. The final stages of Martian core formation occurred much earlier (e.g., Dauphas and Pourmand, 2011) than on Earth (Jacobson et al., 2014). The ‘dry’ Martian late veneer implies that the Martian water was delivered before the late veneer. See text for details.
