Fig. 5: 2-D thermomechanical numerical modeling of large-scale flat subduction and related upper mantle flow.
From: Ghost-arc geochemical anomaly at a spreading ridge caused by supersized flat subduction
Model evolution showing the development of a large-scale flat-slab of about 2700 km in 35–40 Myr. The progressive deformation of the Lagrangian grid (red markers) illustrates the lateral shifting of the upper mantle during the inland growth of the large-scale flat subduction. Material colors as in Supplementary Data Fig. 4; white lines are velocity vectors. The maximum velocity in all panels is 8.4 cm/yr.
