Change title:

Oxygen isotope composition of CI and CM chondrites. Data for CMs and CIs from Clayton and Mayeda (1999); CVs and CKs from Greenwood et al. (2010); COs from Greenwood and Franchi (2004). TFL: terrestrial fractionation line, Y&R: slope 1 line (Young and Russell, 1998), CCAM: carbonaceous chondrite anhydrous mineral line (Clayton et al., 1977; Clayton and Mayeda, 1999).
