Fig. 1. Previously published isotopic anomalies of Ti, Cr, and O in Ryugu and other Solar System materials.

Plots of μ⁵⁰Ti versus μ⁵⁴Cr (A), μ⁵⁰Ti versus Δ¹⁷O (B), and μ⁵⁴Cr versus Δ¹⁷O (C). In these diagrams, Ryugu and CI represent an endmember to the CC array. Data for Ryugu are from Yokoyama et al. (6). The average Ti and Cr isotopic compositions of NC and CC meteorite groups and Earth’s mantle are from the data compilation of Burkhardt et al. (64) and O isotopic data from the compilation of Dauphas (65). Uncertainties for individual groups are the 95% confidence interval of the mean. If not visible, error bars are smaller than symbols.
