O isotope compositions measured by L-SIMS on IOM residues isolated from the Orgueil and Murchison carbonaceous chondrites. The terrestrial fractionation line (TFL), the CCAM line, and the Y&R line are also represented, together with the O isotope compositions of the Sun (17), of CI and CM chondrite components (bulk, matrix, and anhydrous silicates; refs. 21, 22, 26, and 27), of carbonaceous chondrite Ca- and Al-rich inclusions (30–32), chondrules (33–37), and carbonates (38). Estimates for the O isotope composition of CM chondrite primordial water (HW1 and HW2) are from ref. 27 for HW1 and ref. 38 for HW2.
