The stony-iron meteorites. (a) CI-chondrite normalized HSE abundances for pallasites from Wasson and Choi (2003; unfilled circles) and Lee et al. (2006; lines) and (b) ¹⁸⁷Re/¹⁸⁸Os versus ¹⁸⁷Os/¹⁸⁸Os for pallasites and mesosiderites from Shen et al. (1998) and Chen et al. (2002). Shown in (b) is the IIIAB isochron (solid line, from Smoliar et al. 1996) and the best-fit slope for pallasites (dashed line) from Chen et al. (2002), along with calculated age and initial Os isotope composition. Dashed lines and gray symbols in (a) denote Eagle-Station, or anomalous metal pallasites (please refer to text).
