Fig. 19

Bulk resistivity (solid line) of dacitic melt and rock complex at 900 °C, 0.15 GPa as a function of melt volume fraction and of water content in the dacitic melt. The gray shaded area represents the 67% CIR of Fig. 14b, and the solid lines show water content of dacitic melt in weight percent. Note that the upper and lower bound of 67% CIR is the bottom and top of the gray shaded area, respectively. Melt resistivity is calculated from Laumonier et al. (2015). Solid phase resistivity is fixed at 1000 Ωm [e.g., granite data of Kariya and Shankland (1983)]
