Understanding the extreme differentiation of granitic magmas through elemental geochemistry and Fe isotope signatures

The Supplementary Material comprises two files: Supplementary data 1 and Supplementary data 2. Supplementary data 1 includes Supplementary Table S1, which is the bulk-rock major- and trace-element compositions of the BST granitic rocks, and Supplementary Table S2, which contains the parameters used for fractional crystallization modelling by Rhyolite-MELTS. Supplementary data 2 contains Figure S1, which illustrates bulk-rock geochemical variations of the BST granites, And Figure S2, which is a cross plot of Fe isotope compositions for mineral pairs and an evaluation of inter-mineral Fe isotope fractionation, and Figure S3, which shows the relationship between F/Cl ratio versus δ56Fe values and Fe2O3T contents.
