  abstract = {{T}he interplays between deep geodynamic processes and {E}arth-surface erosion processes control the elevation and distribution of land masses, which in turn control environmental changes. {T}hese interactions can be best eval-uated in post-orogenic landscapes defined by decaying crustal deformation. {T}his is the case of the {I}beria peninsula where a growing body of geological evidence suggests the existence of a post-orogenic erosion around 10 {M}a, well documented across the {P}yrenees. {D}ifferent mechanisms have been proposed, including lithospheric and sublithospheric processes, and {E}arth-surface processes triggered by base-level change and/or climate forcing on erosion. {H}ere, we focus on the {E}bro basin, which was a closed basin that opened towards the {M}editerranean in the late {M}iocene. {T}he distribution and exact timing of erosion in the {E}bro basin are, however, only partially known, and do not yet allow resolving the post-orogenic mechanisms involved. {W}e present new ({U}-{T}h-{S}m)/{H}e dates on apatite obtained in sandstones distributed from the edges of the {E}bro basin to its center. {T}he results of the thermal modelling confirm that the exhumation of the {E}bro {B}asin took place between 12 and 6 {M}a, or around 10 {M}a when accounting for model uncertainties. {R}econstruction of the sediment infill reveals that the late {M}iocene post-orogenic deposits were the thickest, between 1 and 1.6 km, near the topographic front of adjacent mountain ranges and were the thinnest, approximately 300 m, in the center. {T}he exhumation in the {E}bro basin occurred after shortening has stopped, and before the {M}essinian {S}alinity {C}risis. {I}t is consistent with the wide-spread 10 {M}a-exhumation event documented throughout {I}beria, from the {A}quitaine basin to the {B}etic {C}ordillera, and provides evidence of large-scale lithospheric and sublithospheric processes that coincide with the cessation of slab retreat in the {W}est {M}editerranean. {W}e propose that a plate-scale uplift driven by deep-seated processes is the main cause of the {E}bro basin incision. {T}he response of the landscape to this geodynamically controlled erosion event led to a complex tectonic reorganization, e.g. along the strike of the {P}yrenees, environmental changes in the {M}editerranean, leading to the {M}essinian {S}alinity {C}risis, and faunal turnover over {I}beria.},
