Oxygen 3-isotope diagram of individual spot analyses of olivine, Low-Ca pyroxene (Lpx), high-Ca pyroxene (Hpx), and relict grains in chondrules in Paris. Error bars, corresponding to the spot-to-spot reproducibility (2SD), are smaller than the symbol sizes. The CCAM (carbonaceous chondrite anhydrous mineral; Clayton et al., 1977), Y&R (Young and Russell, 1998), and PCM (primitive chondrule minerals; Ushikubo et al., 2012) lines are shown for reference. The terrestrial fractionation line (TFL) is also shown.
