The basement top surface is characterized by a structure of paleotopographic
highs and depressions (Fig. 5.10). The two main sub-basins, WAB and EAB, stand
out together with a secondary set of satellite basins found in the central segment
(Motril, Southern Alboran, Central Alboran Trough, and Intermediate basins;
Vázquez 2001) and the southeastern margin of the Alboran Sea (Habibas and
Pytheas basins; Martínez-García et al. 2013) (Figs. 5.6 and 5.10). In addition, several
structural highs are seen to have a different expression in the current seafloor
morphology. They correspond to the highs of the Motril-Djibouti marginal plateau
(Palomino et al. 2011), the Alboran Ridge, the DSDP high (whose superficial
expression corresponds to Ibn-Batouta Bank), and the highs related to the Moulouya
marginal plateau (Fig. 5.6; Chap. 6). The basement paleotopography would be
