Δ17O vs. ε54Cr in impact glasses and tektites from this study compared with chondrites, achondrites and large planetary bodies. The plot is modified from refs. 3, 26, 58 with new data from this study plotted as yellow symbols (circle—SBM-88; reversed triangle—IR-7; diamond—IR-8), with 2 s.e. uncertainties plotted. For oxygen, the error bars are smaller than the corresponding symbol size. Different hues of orange from light to dark represent different classes of carbonaceous chondrites (CI, Tagish Lake, CR, CB, CM, CV, CO, CK—red spot), the single point with high Δ17O ~2.5‰ represents Rumuruti chondrites. Different hues of blue from light to dark represent ureilites (farthest from Earth), mesosiderites–HED meteorites–pallasites–IIIAB irons group, ordinary chondrites, aubrites, angrites and enstatite chondrites (near-identical to Earth). Triangle—Mars; star—Earth; crescent—Moon
