Two strong (high amplitude) characteristic reflectors have been interpretated as extensional faults; one of the m (R. 1 ) corresponds basement-cover fault, whereas the deepest one (R.2) is an intra basement fault. A n inversion of interval velocity has been associated with R.2 and points to the existence of an anomalous high-velocity body over R.2. The ocurrence of peridotitic outcrops in the Betic Cordillera, and the positive gravity anomalies in the continental margin, do suggest that our data can be explained by means of a peridotitic sheet-like bodys and wiched between two extensional faults in the basement of the northwestern continental margin of Alboran SeaspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Seismic reflection profilesInterval velocityExtensionai faultsPeridotitic bodyContinental marginALboran Seaconference outputopen access
