In the original publication,the vertical coordinate in Fig. 7 is incorrectly published as δ56Fe instead of δ57Fe. The correct Fig. 7 is provided in this correction.

Fig. 7 Iron isotope compositions of various geological samples relative to IRMM-014 analyzed over the period of three months.The gray line represents a linear regression of δ56Fe vs.δ57Fe with a slope of 1.490 ± 0.015 (SE) (R2 = 0.9665, N = 332). This relationship is statistically consistent with both theoretical predictions of massdependent isotope fractionation (slope of 1.475; Young et al. 2002)and with previously measured isotopic mass-dependent fractionation trends using Nu Plasma (slope of 1.482; Chen et al. 2017a)
