Resum

This paper presents a new view of recent sedimentation in the Alboran Sea, based on the analysis of the largest database of available seismic profiles in that sea. The results reveal that contourites represent the main morphosedimentary features that characterize the margins and basins. Several types of contourite features have been characterized, both depositional (plastered, sheeted, elongated-separated, confined, and channel-related) and erosive (moats, terraces and furrows). These elements are interrupted by the construction of turbidite fans, mainly in the Spanish margin, and by sedimentary instabilities that locally affect to the open slope, Alboran Ridge and morphological highs. This new morphosedimentary view of the Alboran Sea reveals for the first time the important role of along slope processes (transport, sedimentation and erosion) associated with Mediterranean water masses.
