Mo isotope compositions of the CC and NC meteorite groups in a μ⁹⁴Mo versus μ⁹⁵Mo diagram (using the same color scheme as in Fig. 8). The blue CC-line fit is taken from Budde et al. (2016). NC meteorites are plotted close to an s-process mixing line through ureilite (thick red s-Ur line). Thin contours give the unprocessed mass fraction encompassing the OC and EC chondrites. The dashed gray line represents the line fit through the NC group obtained by Yokoyama et al. (2019). Literature data sources: CI (Burkhardt et al. 2011), CO (Burkhardt et al. 2014), CV, OC, EC (Yokoyama et al. 2019), ureilites, angrites, and mesosiderites (Budde et al. 2018). The mesosiderites may represent Vesta-like material (Haba et al. 2019).
