Supplementary Data for 'Experimental constraints on the sources of lithium-rich granites and pegmatites'

To test the anatectic origin of lithium-rich granites and pegmatites, partial melting experiments were performed on variably enriched metasedimentary rocks. Here, the major and trace element compositions of minerals and melts from the starting materials and the experimental run products are presented. Geochemical analyses are supported by Supplementary Tables 1 to 14 from Horányi et al. (2025).
