| Since the Miocene, the thinned continental crust below the Alboran Sea as well as its overlying sedimentary cover have been undergoing deformation caused by both convergence of Eurasia and Africa and by deep processes related to the Tethyan slab retreat. Part of this deformation is recorded at the Xauen and Tofiño banks in the southern Alboran Sea. Using swath bathymetry and multichannel seismic reflection data, we identified different stages and styles of deformation. The South Alboran Basin is made up of Early Miocene to Pliocene sedimentary layers that correlate with the West Alboran Basin depocenter and are dominated by E‐W trending folds and thrusts. The Xauen and Tofiño Banks first recorded the phase of extension and strike‐slip movement during the... |

| In active basins, tectonics can segment the continental shelf and control its stratigraphic architecture and physiography. Segmentation can explain the local evolution and morphology of the continental shelf because of sea-level variations, local tectonic segmentation and hydrodynamic processes. Here we investigate the tectonically active Morocco continental margin (southern Alboran Sea) using high-resolution seismic profiles and multibeam bathymetric data. The active faults bounding the transtensive Nekor basin triggered the segmentation of the shelf into three sectors showing different subsidence rates: a western sector corresponding to an extensive fault relay, a central sector corresponding to the subsiding Al-Hoceima Bay and an eastern sector... |

| The Bransfield Basin is a young active rift basin located between the northern margin of the Antarctic Peninsula and the South Shetland Islands margin. Deception and Bridgeman Islands divide the Bransfield Basin in three subbasins, the western, central and eastern. Specific morpho-tectonic features and sediment fill differentiate each subbasin. The structure and geodynamic evolution of the Central Bransfield Basin, which is in a stage of incipient seafloor spreading, have been investigated in detail from a dense grid of single-channel seismic reflection data. The Central Bransfield Basin is dominated by two families of normal faults which are oriented northeast and northwest. The NE-trending faults define three graben systems that are roughly parallel to... |
