The Alboran Sea (Western Mediterranean) revisited with a view from the Moroccan Margin

Abstract This paper presents a new depth to acoustic basement map based on a grid of seismic profiles. In the Western Alboran Basin the basement is more than 10 km deep. An examination of a seismic profile of this region suggests that Late Oligocene–Early Miocene 5 km thick synrift formation has been accumulated in this basin. This West Alboran basin has been formed in an extensional setting, but in a fore‐arc position, south of the Balearic Islands then westwards transported behind a subduction zone.
