(26Al/27Al)0 vs. Δ17O for (a) LL3 (Kita et al. 2000; 2010), Acfer 094 (Ushikubo et al., 2012; 2013), and CO3 (Kurahashi et al., 2008; Tenner et al. 2013) chondrite chondrules, and for (b) CR2 chondrite chondrules (this study; Schrader et al., 2017: S17) and Stardust comet particles Iris (Ogliore et al., 2012) and Pyxie (Nakashima et al., 2012; 2015). Mg# ranges and uncertainties are as reported in each study, with the exception of chondrule Mg#’s from Schrader et al., 2017, which are recalculated as described in section 4.3.1.. Relative ages are calculated according to Eqn. 1 and use a canonical CAI (26Al/27Al)0 of 5.23 × 10˗5 (Jacobsen et al., 2008; MacPherson et al., 2010).
