| Sumario: | An analysis ofmultichanell seismic profiles leads to define the main fracture zones in the northeastern continental margin of Spain. Two fault systems have been mapped: I) NE-SW to N-S that defines a classical extensional model of passive margin, with blocks limited by .lis tric faults and rotated around horizontal axis; 2) NW-SE to WNW-ESE that constitutes a Transfer Zone in the extensional stage of the margin (Late Oligocene-Burdigalian) and a localized extensional region since Tortonian times (Basins of Rosas and Bagur). This Transfer Zone limited two differents areas in the Western Mediterranean basin in relation with the rotation of the Corso-Sardinian block |
