Ivuna-type chondrites Archives - Astrobiology

Iron isotopic compositions of CI chondrites, CV chondrites, and terrestrial rocks. The μ 54Fe and μ58Fe data for different sample types (see legend) from this study (solid symbols) together with data from previous works (open symbols) (Table S1). Error bars indicate 95% confidence intervals. CV chondrites have similar μ 58Fe but elevated μ 54Fe compared to terrestrial samples. CI chondrites have similar μ 54Fe but elevated μ 58Fe compared to terrestrial samples. -- astro-ph.EP
