Supplementary Figure 2: Rare earth element (REE) concentrations for (a) shergottites, (b) shergottites with offset concentrations by multiples of 100, 1, and 0.01 for enriched, intermediate, and depleted shergottites, respectively. This better illustrates the distinct REE patterns for each shergottite geochemical group, namely the relative enrichment in the light REE, (c) nakhlites and chassignites, and (d) ungrouped samples NWA 7034 and ALH 84001.
