Figure S8. Vs as a function of melt fraction over aspect ratios indicative of textural equilibrium, 0.1 to 0.15. Solid phase Vs values were determined using the ~70 ka Banco Bonito rhyolite composition at 170 MPa (~5 km depth), and 700 C°. A density of 2.2 kg/m3 and bulk modulus of 9 GPa were assumed for the melt phase.
