Extended Data Fig. 7: Predicted melt compositions for variable Temperature-X(H2O) water-fluxed batch melting scenarios for Harcuvar Mountains migmatite sample TLAZ22-08.
From: Porphyry copper formation driven by water-fluxed crustal melting during flat-slab subduction
Petrological modelling outputs showing predicted melt volume, water content (wt%) in the melt and volume proportions of k-feldspar, plagioclase and garnet, with major element composition (wt%). Calculations were performed isobaric at a pressure of 0.75 GPa, varying temperature and X(H2O) (0.25–6 wt% H2O). Red and yellow lines mark average biotite ± hornblende and muscovite ± garnet-bearing granites, and red and yellow fields mark the observed range in biotite ± hornblende and muscovite ± garnet-bearing granites respectively. All geochemical data of Laramide granites is available in Supplementary Table 2.
