Extended Data Fig. 9: C and N isotopic compositions of organic matter in Bennu sample OREX-501018-100.

From: The variety and origin of materials accreted by Bennu’s parent asteroid

Extended Data Fig. 9

C and N isotopic compositions determined by in situ NanoSIMS isotope mapping show discrete regions of organic matter having highly anomalous N isotopic compositions and a smaller range of C isotopic compositions. Sources of non-Bennu data are: Ryugu29,30; Orgueil29; Murchison acid-insoluble residue28; comet Wild232,140. Errors are not shown for clarity and can be found in Supplementary Table 13. The average error for the Bennu data is 85 ‰ for δ15N, and 42 ‰ for δ13C.
