Movie M1: Oceanward rift migration during formation of Santos–Benguela ultra-wide rifted margin

Evolution of the Kinedyn model used to simulate the tectonic evolution of Santos–Benguela Conjugate Margin (Figs 8 and 9). Top panel shows a general view of the model; middle panel shows a zoom of the model. The upper, lower crust, mantle lithosphere and asthenosphere are colour coded. Light brown: upper crust; beige: lower crust; green: mantle. The red- and blue-shaded areas indicate the areas of highest plastic and ductile strain rate. The age of the sediments is colour coded: rainbow scale shows sediments of synrift age. Dashed blue lines are sea-level; dashed black lines are isotherms.
