Figure 6. Evolution of phase proportions in the crystallized melts corresponding to the average bulk-rock compositions of the LZc and UZa subzones. Calculations of equilibrium crystallization were carried out using COMAGMAT-3.65 at P =1 kbar and 0.1 wt.% H2O: open systems correspond to the QFM buffer; closed systems are defined by Fe3+/(Fe3+ +Fe2+ ) = 0.15 in the starting melt.
