  1. The data for water-rich CI and CM chondrites and for CR clan Tafassites are shown as well. Notes: \(^{(\text {Bre})}\) breunnerite, \(^{(\text {Cal})}\) calcite, \(^{(\text {Dol})}\) dolomite, \(^{(\text {Pho})}\) phosphate, \(^{(\text {Pl})}\) plagioclase, \(^{(\text {Px})}\) pyroxene, \(^{(\text {W})}\) whole-rock, \(^{(\text {Ol})}\) olivine, \(^{(\text {Car})}\) carbonates. The age data are from39(CR),25(Flensburg),41(NWA 011 and NWA 2976),23,42(NWA 4587, NWA 7680),22,43(NWA 6704),23(NWA 10132),15,41(Tafassites),13,39(CI, CM). The closure and formation temperatures are from44,45(CR1-3),25(Flensburg),46,47 and48(NWA 011, NWA 2976, NWA 4587, NWA 6704, NWA 10132),15(Tafassites),13(CI, CM). A CAI age of 4567.9 Ma was used.
