AB The Iberian Chain is a wide intraplate deformation zone formed by the tectonic inversion during thePyrenean orogeny of a Permian –Mesozoic basin developed in the eastern part of the Iberian Massif. The N – Sconvergence between Iberia and Eurasia from the Late Cretaceous to the Lower Miocene times producedsigni cant intraplate deformation. The NW –SE oriented Castilian Branch of the Iberian Chain can beconsidered as a “key zone ” where the proposed models for the Cenozoic tectonic evolution of the IberianChain can be tested. Structural style of basin inversion suggests mainly strike slip d–isplacements alongprevious NW –SE normal faults, developed mostly during the Mesozoic. To con rm this hypothesis, structuraland basin evolution analysis, macrostructural Bouguer gravity anomaly analysis, detailed mapping andpaleostress inversions have been used to prove the important role of strike slip deformation. In addition, wedemonstrate that two main folding trends almost perpendicular (NE SW t–o E W an–d NW SE) w–eresimultaneously active in a wide transpressive zone. The two fold trends were generated by dierentmechanical behaviour, including buckling and bending under constrictive strain conditions. We propose thatstrain partitioning occurred with oblique compression and transpression during the Cenozoic.
