Abstract
Los principales rasgos de la topografía de Iberia, tanto onshore, como en el offshore Atlántico, son el resultado del desarrollo de pliegues litosféricos desacoplados de los de la Corteza Superior bajo un contexto de acercamiento N-S entre Iberia y Eurasia durante el Oligoceno – Mioceno Inferior. El acoplamiento mecánico entre Iberia y África, produjo una deformación muy distribuida hasta el Anti-Atlas en Marruecos. El emplazamiento del Bloque de Alborán desacopló Iberia de África de E a O, con lo que sólo en la zona más Occidental de la Península Ibérica, y en el offshore Atlántico, continúa aún activo este proceso.
The main topographic features of Iberia, onshore and in the Atlantic offshore, are the result of the development of Lithospheric folding and decoupled Upper Crustal folds under a N-S approach between Iberia and Eurasia during the Oligocene-Lower Miocene. The mechanical coupling between Iberia and Africa, produced a very distributed deformation up to the Anti-atlas in Morocco. The emplacement of the Alboran Block decoupled Africa from Iberia from E to W, with what only in the westernmost zone of the Iberian Peninsula, and in the Atlantic offshore, this process still continues nowadays.
