Supplementary Movies for Pérez-Gussinyé et al. (2023) Synrift and postrift thermal evolution of rifted margins: a re-evaluation of classic models of extension Accepted in GSL Special Publications

<p>Movie S1. Evolution of deformation for the three models shown in Figures 2 and 3. Full extension rate is 10 mm/yr. Sedimentation rate is given in Figures 2 and 3 and Methods (see also Table 1). Red shading shows brittle strain rate, blue shading shows ductile strain rate. The sediments are color coded with age since the start of rifting. The color circles are trackers. The color conventions for the phases are the same as in Figures 1 and 2.</p><p>&nbsp;</p><p>Movie S2. Top: Thermal evolution of the 10 mm/yr full rifting velocity model without sedimentation along with markers (model shown in Figures 2a-e and 3a-c). Grey shading indicates strain rate. Note the development of small scale convection cells. Middle: Evolution of the basement heat flow of markers shown in top panel. Bottom: Evolution of the basement temperature at markers shown in top panel. Note that the horizontal and vertical scale change in the postrift to better show the small scale convection in the top panel.</p><p>&nbsp;</p><p>Movie S3. Top: Thermal evolution of the10 mm/yr full rifting velocity model with average sedimentation along with markers (model shown in Figures 2f-j and 3d-g). Grey shading indicates strain rate. Note the development of small scale convection cells. Middle: Evolution of the basement heat flow of markers shown in top panel. Bottom: Evolution of the basement temperature at markers shown in top panel. Note that the horizontal and vertical scale change in the postrift to better show the small scale convection in the top panel.</p><p>&nbsp;</p><p>Movie S4. Top: Thermal evolution of the 10 mm/yr full rifting velocity model &nbsp;</p><p>with largest sedimentation along with markers (model shown in Figures 2k-o and 3h-k). Grey shading indicates strain rate. Note the development of small scale convection cells. Middle: Evolution of the basement heat flow of markers shown in top panel. bottom: Evolution of the basement temperature at markers shown in top panel. Note that the horizontal and vertical scale change in the postrift to better show the small scale convection in the top panel.</p><p>&nbsp;</p><p>&nbsp;</p><p>Movie S5. Evolution of temperature field for the 10 mm/yr full rifting velocity without sedimentation, (model shown in Figures 2a-e and 3a-c). b) and c) show the geotherms of trackers shown in a) computed from the dynamic model (solid colored lines), and from the ´1-D temperature´ solution (dashed colored lines). The black curve shows the initial geotherm used for the dynamic temperature and for the ´1-D temperature´ calculations. Grey shading indicates strain rate. Note that the horizontal scale is changing to show the rifted margins as the model evolves.</p><p>&nbsp;</p><p>Movie S6.
