Matrix abundances vs. bulk Zn and C contents. In general, the abundances of Zn (Wasson and Kallemeyn 1988; Kallemeyn et al. 1991; Brown et al. 2000; Bischoff et al. 2011) and C (Alexander et al. 2012; Alexander et al. 2014a) are what would be expected if the matrices in these chondrites were dominated by CI-like material. The exception is the bulk C content of Tagish Lake (TL), but this seems to be because it is unusually rich in carbonate. The C contents for the OC, CO and CV chondrites are for the most primitive members of their groups (Semarkona, DOM 08006, and Kaba, respectively).
