Perple_X tables for water capacity and melt prediction. x-axis represents temperature (°C) and y-axis represents pressure (GPa). Red line represents hydrated solidus. (a) Sediment water capacity; (b) and (c) oceanic crust (basalt compound) water capacity and melt respectively; (d)–(f) mantle (peridotite compound) water capacity with 1 wt%, 2 wt%, and 12 wt% bulk water content respectively; (g)–(i) mantle melt with 1 wt%, 2 wt%, and 12 wt% bulk water content respectively.
