Water transport by nominally anhydrous minerals. Shown are the bulk subduction water fluxes due to 400 ppm of water in the nominally anhydrous minerals of the oceanic crust, and of 1400–2900 ppm of water in the mantle peridotite above the subducted slab that gets dragged down with the plate. The 1400 to 2900 ppm correspond to the bulk water solubility in peridotite at 3–4 GPa and 800–1000 °C, i.e., below the volcanic arc. Assumed is a total length of subduction zones of 60,000 km and a water-saturated peridotite layer (modeled as 60% olivine and 40% orthopyroxene) above a slab of 10 km thickness.
