Fig. 20

Bulk resistivity (solid line) of andesitic melt and rock complex at 900 °C, 0.29 GPa as a function of melt volume fraction and of water content in the andesitic melt. Melt resistivity calculations from Guo et al. (2017) are shown by the broken line, and from Laumonier et al. (2017) are shown by the solid line. Solid phase resistivity is fixed at 500 Ωm [e.g., rhyolite data of Kariya and Shankland (1983)]. Others are the same as Fig. 19
