(a) CI-chondrite normalized HSE abundances and (b) 187Re/188Os versus 187Os/188Os for martian meteorites. Isochrons in (b) are at 586 Ma and 164 Ma, with the 164 Ma age originating from an errorchron age of 164 ±12 Ma (187Os/188Osi = 0.12516 ± 18; MSWD = 2.7) from EETA 79002 (Brandon et al. 2012). Data from Riches et al. (2011), Brandon et al. (2012), Dale et al. (2012) and Filiberto et al. (2012).
