Resumen
The Mediterranean realm is characterized by Neogene tectonically-imbricated arcs and their corresponding basin systems. Although the structures have been the focus of numerous projects, and some arcs and basin deposits have been well studied, particularly in outcrops onshore, most basin-arc pairs lack modern, comprehensive geophysical studies. The lack of data precludes any detailed knowledge of crust and mantle structure, of the nature of the basement, and thus the understanding of their tectonic structure and sedimentary deposits is thus incomplete. The limited geophysical information has restrained the study of the interplay between tectonic, magmatic, and sedimentary processes in those complex systems. During the last 6 years an initiative led by scientists from the Spanish National Research Council (CSIC) in Barcelona and international collaborators has collected an extensive geophysical data base across the Gulf of Cádiz, and the Alborán, South Balearic, and Tyrrhenian basins. The new wide-angle seismic data, deep-penetration multichannel seismic reflection images, and high resolution seismic reflection records show a surprising variability in nature of crust and tectonic structure that controlled the formation of the systems, and the distribution of active faulting across the regions.
