Incision in the Ebro Basin since 10 Ma in two key areas, the Zaragoza area (black) where the end of basin infilling is recorded, and the Aragón valley (brown). Rectangles figure the constraints. Numbers represent the incision rate in m/Ma. The path for the period between 10 and 3 Ma is shown with a dashed line, which figures the possibility the current topmost strata has been buried for a while (García-Castellanos and Larrasoaña, 2015). The Zaragoza area does not show a marked change at ∼ 3 Ma. On the contrary, both records suggest a threefold increase in incision rates after the MPT.
