Abstract
The lithosphere of Iberia has been formed through a number of processes of continental collision and extension:
in Lower Paleozoic, the collision of three tectonics blocks produced the Variscan Orogeny, the main event of
formation of the lithosphere. The subsequent Mesozoic rifting and breakup of the Pangea had a profound effect
on the continental crust of Iberia. Since the Miocene, the southern interaction between Africa and Iberia is
characterized by a diffuse convergent margin that originates a vast area of deformation. The impact of this
complex tectonic in the structure of the Lithosphere remains an incognito, especially in its western part.
Project WILAS (PTDC/CTE-GIX/097946/2008) is a 3 years project funded by FCT in which a temporary
network of more than 20 BB seismic stations is being deployed in Portugal between 2010-2012. It will extend to
the western border of Iberia the coverage of the TOPO-IBERIA project.
The project aims to image the 3D structure beneath W Iberia. The knowledge of the Crust, Lithosphere and
Astenosphere seismic structure must be dealt at different scales, involving different but complementary methods
