%X Effective elastic thickness of the lithosphere of the Iberian peninsula was estimated from acoherence analysis of topography and gravity spectra, for which a multitaper technique wasused. Coherence estimates provide an average Te value of 17 ± 4 km. To verify the Te derivedfrom the spectral analysis, we compare it to independent Te estimates from strength envelopesconstructed for some tectonic units located at the interior of the Iberian peninsula.We obtain Tevalues ranging from 10 to 25 km. These values are consistent with coherence results. Tectonicevolution of the area involved an Early Mesozoic rifting (Late Permian—Early Cretaceous)and a subsequent period of compression. Present morphotectonic units result from Alpinedeformation events (mainly Neogene). No widespread volcanism activity or/and high heatflow values have been reported to have occurred during intraplate domain deformation. TheIberian lithosphere response to loading primarily reflects its pre-existing inherited mechanicalstructure, which has remained thermally relatively unperturbed.
