Figure 8

C-isotopic ratios of DOM 08006 presolar SiC grains compared to literature data for ~16,000 isolated grains from acid residues (top panel; Zinner, 2014) and 118 grains found in situ in previous studies (bottom panel; Floss and Stadermann, 2009a; Nguyen et al., 2010; Bose et al., 2012; Leitner et al., 2012b; Haenecour et al., 2018). The vertical solid line indicates the terrestrial ratio of 89 and the vertical dashed line indicates the peak of the isolated grain distribution at 12C/13C=57.
