Fig. 5: Global mantle convection model showing the relationship between horizontal mantle flow and slab detachment.
From: Mantle-driven plate convergence due to slab detachment

a and b Global mantle flow model of ref. 42 at 200 and 250 km depth, respectively. c and d Global mantle flow model of ref. 40 at 200 and 250 km depth, respectively. e and f Drag coefficient calculated from the model of (a and b). g and h Drag coefficient calculated from the model of (c and d). Black lines with arrows show the direction of mantle flow. Color palettes at the figure base represent (from left to right): horizontal mantle flow velocity (a–d), slab depth (a–h), and mantle drag coefficient (e–h).
