Fig. 1: Extensive depletion of moderately volatile elements (MVEs) in angrites.

a Elemental concentrations of angrites analyzed in this study are plotted relative to concentrations in CI chondrites45 (both are normalized to Mg = 1.0) versus 50% nebular condensation temperatures57. Lithophile elements are shown in solid symbols and siderophile elements are shown in open symbols. REE refers to rare earth elements. b Angrites, as indicated by the blue field, represent the endmember for MVE depletion among planetary basalts. The degrees of volatile depletion in AdoR, the bulk silicate Moon, Vesta, Earth, and Mars are assessed by CI-normalized Rb/Sr and K/U ratios from ref. 8.
