Fig. 6. F/Cl vs F content of partial melts for metasomatized mantle sources (blue lines) and F-rich sources (green lines), for different modal abundances of amphibole and mica. The grey area represents the possible F/Cl values of melts derived from metasomatized mantle sources, while the light green area represents possible values of melts derived from F-rich sources. The dark green area represents the overlap of F/Cl values between sources that have different halogen contents, mineral abundances and underwent different degrees of partial melting. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
