Meteoritical Bulletin: Oxygen Isotope Plots

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).
