Abstract We report the bulk C abundances, and C and O isotopic compositions of carbonates in 64 CM chondrites, 14 CR chondrites, 2 CI chondrites, LEW 85332 (C2), Kaba ( CV 3), and Semarkona ( LL 3.0). For the unheated CM s, the total ranges of carbonate isotopic compositions are δ 13 C ≈ 25–75‰ and ...
