An example of lunar impact melt breccia (a) variations of Re, Os, Ru, Pt, Rh, Pd and Au with Ir, (b) CI-chondrite normalized HSE abundances and (c) 187Re/188Os versus 187Os/188Os for the fine-grained sub-ophitic impact melt 67935. This particular sample has yielded the only Re–Os isochron for a lunar impact melt rock, of 4.21 ± 0.13 Ga, yet has one measured fraction that deviates from a potential linear correlation in (a) and has a flatter pattern (b). Data from Fischer-Gödde and Becker (2012).
