Plots of (A) Δ¹⁷O versus ε⁵⁰Ti and (B) Δ¹⁷O versus ε⁵⁴Cr for bulk carbonaceous chondrite samples studied here and from the literature. The ε⁵⁰Ti and ε⁵⁴Cr data for Coolidge, EET 83226, EET 83355, NWA 5958, MAC 87300, MAC 87301, MAC 88107, LEW 85332, and GRO 95566 are from this study, as are the Δ¹⁷O data for each of these samples except GRO 95566 (Clayton and Mayeda, 1999) and NWA 5958 (Jacquet et al., 2016). The Δ¹⁷O, ε⁵⁰Ti, and ε⁵⁴Cr data for individual CM, CO, CV, CK, CR, CB, and CI chondrites measured previously are from: (1) Shukolyukov and Lugmair (2006); (2) Trinquier et al. (2007); (3) Trinquier et al. (2009); (4) Qin et al. (2010); (5) Yamashita et al. (2010); (6) Zhang et al. (2011); (7) Zhang et al. (2012); (8) Sanborn et al. (2019); (9) Weisberg et al. (1993); (10) Clayton and Mayeda (1999); (11) Greenwood and Franchi (2004); (12) Greenwood et al. (2010); (13) Schrader et al. (2011); (14) Hewins et al. (2014); (15) Jacquet et al. (2016); and (16) Williams et al. (2020), as denoted by the numbers in parentheses in the legend. Error bars are internal 2SE or external 2SD, whichever is larger.
