Fig. 1. Summary of NWA 7034 and paired stone radiometric ages, and chronology of major events experienced by the breccia.
Dates from each study are reported in Supplementary Data 1. The ejection event is constrained from 22Ne/21Ne cosmic ray exposure ages12, 13. Whole rock (w.r), zircon and or baddeleyite (zr.b), apatite (ap), and augite (aug) on which ages have measured are also mentioned. The different chronometers used in these studies are reported (Sm-Nd, Pb-Pb, U-Pb, K-Ar, U-Th/He, U-Th-Sm/He). Note that green, red and blue boxes correspond to resetting ages of the noted chronometer. Reset ages in green are widely interpreted as the disruption induced by an impact-derived heating event that has excavated the oldest components of the breccia ~1.5 ago9, 11, 23, 26, although its precise age is still unconstrained due to the wide range of isotopic dates reported in the literature.
