μ25Mg of pallasites, primitive achondrites and chondrites (blue) reported as the parts per millions deviations from the terrestrial standard DSM-3. Also shown are Mg isotope data for Earth’s mantle (light gray box, [−128 ± 23 (2sd) ppm]; average calculated from pristine mantle peridotites and olivines from Young et al., 2009; Handler et al., 2009; Bourdon et al., 2010; Schiller et al., 2010; Teng et al., 2010; Huang et al., 2011; Liu et al., 2011; Pogge von Strandmann et al., 2011). Data for CI chondrites (Orgueil; Alais; Ivuna), ordinary chondrites (OC; Kramer Creek [L4]; Tennasilm [L4]; Barratta [L3.8]; Heredia [H5]), one enstatite chondrite (EC; SAH 97159 [EH3]) and the acapulcoite (DHO 1222) are from Larsen et al., 2011 (L2011). Gray shades represent weighted averages and their associated uncertainties (2sd). Error bars for individual samples represent the internal errors (2se).
