Oxygen isotope composition of CR and CH chondrites. Data for CH chondrites from Clayton and Mayeda (1999), CR chondrites from Clayton and Mayeda (1999) and Schrader et al. (2011). 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).
