The errors for ⁵⁵Mn/⁵²Cr ratios are 5%. The ⁵⁵Mn/⁵²Cr for H chondrite samples in [7] Pedersen et al. (2019) are re-measured (same solution) by MC-ICP-MS in this study.

The Fe/Cr (atom) ratios for CB and CH chondrites: PCA 91467, 97; A-881020, 115; QC 001, 25; HaH 237, 235

The errors for O isotope data in [18] are 1SD of multiple O isotope data, and in [10] and [11] are quoted as 0.08 from [9].

The ε⁵³Cr 2SE uncertainty for PCA 91467 is less than 0.004. The CB and CH samples in this study, including PCA 91467, MIL 05082, A-881020, QC 001 and HaH 237 may not represent the bulk composition of the parent chondrites given the clear evidence for sample heterogeneity in CB and CH chondrites and the fact that the mass of our samples is relatively small. The ε⁵⁴Cr data for Bencubbin is the average (with 2SD uncertainty) of two data (silicate > metal and silicate < metal) in Trinquier et al. (2007). The ε⁵⁴Cr data for Gujba is the average (with 2SD uncertainty) of the data for chondrules and metals in Yamashita et al. (2010).
