Fig. 4: Water contents of slab materials and the slab surface temperature in representative models.
From: Horizontally forced initiation of the Izu-Bonin-Mariana subduction zone

a–c Water contents of slab of lithospheric mantle (a), slab crust (b), and sediments (c) at different temperature-pressure conditions43. Lines with age demonstrate the evolution of slab surface temperature in the first-type model (Run 10). d–f The plotting habits are the same as in (a–c), except that slab surface temperature is from the second-type model (Run 71).
