Refraction/wide angle seismic profiles acquired in 2000 during the Parsifal cruise across the Southportuguese Zone, the Algarve Basin and the South Iberian continental margin have allowed us to determine the crustal structure west of the Bank of Guadalquivir, which has been constrained by gravity modelling. According to the crustal model obtained, a crustal thinning of 11 km takes place from the shoreline to the Guadalquivir Bank area, where enhanced crustal attenuation has been found. Under the sedimentary cover, the velocity structure consists of a wedge-shaped upper crust with velocities between 5.8 and 5.9 km/s, characterised by a pronounced thickness variation. In the middle-lower crust, velocity increases from 6 to 7 km/s.
