Inter-mineral oxygen isotope ratios of chondrules from this study that have plagioclase data for comparison. Oxygen isotope data are from Tenner et al. (2015). Low-, mid-, and high-Ca pyroxene data have wollastonite endmember contents of 0.8–3, 7–9, and 33–37, respectively. Uncertainties are the 2SD external reproducibility of bracketing standard measurements. Shown are the primitive chondrule mineral (PCM; Ushikubo et al. 2012), carbonaceous chondrite anhydrous mineral (CCAM; Clayton et al. 1977), Young and Russell (1998), and terrestrial fractionation lines.
