From: Grain-size-evolution controls on lithospheric weakening during continental rifting
a, Temporal evolution of the laterally averaged integrated strength (boundary force) of pure dislocation and grain-size-dependent composite diffusion–dislocation-creep experiments. b, Laterally (x = 990–1,000 km) averaged lithospheric strength profiles after 5 Myr. For colour code, see a. c, Strength and grain-size profile along lithospheric shear zone at 5 Myr. Location of profile indicated in Fig. 1b.
