Extended Data Fig. 3: The composition of CF melt inclusions (MIs), compiled from the literature.
From: Escalation of caldera unrest indicated by increasing emission of isotopically light sulfur
a, The trachybasaltic MIs entrapped in crystals from the Minopoli and Fondo Riccio eruptions (studied here for sulphur content and sulphur isotope composition; Supplementary Table 2) are the most mafic volcanic products ever measured37,65,79,80 at CF, and hence the most representative of the deep parental melts. In (b) the model predicted evolution of dissolved melt H2O and S contents (data from model runs 1-10 in Supplementary Data 1) are shown for comparison, and nicely reproduce the sulphur (and H2O) loss from melt (to the vapor phase) upon decompressional degassing to ~3-6 km (the storage zone of more evolved – trachytic to phonolitic – and volatile-poor melts39).
