Figure 3. Magnesium normalized volatile element abundances in the BSE relative to CI as a function of their 50% condensation temperature26,41,46.

Figure 3

Lithophile plateau volatile element abundances in the BSE (TC < 750 K) can be explained by the addition of 10 - 15 wt.% CI-like material within Earth’s building blocks before core formation ceased. Sulfur, Se and Te were likely completely stripped of the mantle during this event before late accretion of 0.4 - 0.7 wt.% CM-like material3. Error bars represent the propagated uncertainties of CI chondrite and BSE concentrations. For data sources see Supplementary Table 1.
