Abstract

Along the Alboran Basin (Western Mediterranean) is located the diffuse plate boundary between Iberia and Africa. This wide deformation zone is controlled by the NW-SE convergence of these two plates. Deformation is accommodated by a large number of faults, where are placed offshore and onshore. The Alboran basin has a complex evolution, and the processes which led to the basin formation in the early Miocene are still under discussion. It is an active zone, so it involves a seismic and tsunamigenic hazard for the region. With the objective of improve the knowledge of this area, the TOPOMED-GASSIS cruise took place in October 2011. During this cruise, a deep penetration dataset was acquired using new instruments that allow the imaging of the basin at a crustal scale. The result is a series of multichannel seismic profiles with unprecedented quality in the region, which permit to use state of the art processing and imaging techniques to obtain the deep tectonic structure of the plate boundary and also a good resolution in the sedimentary infill of the basin. Moreover, we carried out Pre-Stack Depth Migration algorithms to selected profiles, in order to show the real geometry of the structures in depth and also to obtain the fault parameters.
