Metallogenic provinces are not self-evident geochemical provinces. A scheme to quantify the processes of »geochemical heritage« and »magmatic differentiation« in the evolution of tin granites is presented. Geochemical heritage can be limited to a maximum contribution in the 5–10 ppm Sn range. The crucial process in the formation of tin granites is magmatic differentiation. A variable bulk Sn distribution coefficient controls the tin ore potential of granites.
