(Table S2) Data for compositional traverses perpendicular to olivine rims, and results of diffusion modelling

C0 and C1 are the compositions of olivine cores and rims, respectively, for the one-dimensional diffusion model.Dt is calculated from the best-fit of an analyzed traverse by an error function; L is the profile length calculated as L = 4*sqrt(Dt);t is the calculated diffusion time using a diffusion coefficient of 1.6*10-17 m2s-1.
