We surveyed the Owen Fracture Zone at the boundary between the Arabia and India plates in the NW Indian Ocean using a high-resolution multibeam echo-sounder (Owen cruise, 2009) for search of active faults. Bathymetric data reveal a previously unrecognized submarine fault scarp system running for over 800 km between the Sheba Ridge in the Gulf...
The north Ligurian margin is a complex geological area in many ways. It has witnessed several phases of highly contrasting deformation styles, at both crustal scale and that of shallower cover tectonics, simultaneously or in quick succession, and with significant spatial variability. This complex interplay is mirrored in the resulting intricate...
The North Anatolian Fault (NAF) is a >1200 km-long continental strike-slip fault system, acting as the plate boundary between Eurasia and Anatolia. West of the Yeniçaga fork in Turkey, the NAF divides in two main strands: the Main Marmara Fault crossing the Marmara Sea to the North, and a southern branch of the NAF crossing the Biga Peninsula....
Le bassin Ligure, à la jonction entre la mer Méditerranée occidentale et la chaîne Alpine, résulte d'une extension arrière-arc liée au retrait de la plaque plongeante Ionienne depuis l'Oligocène jusqu'au Miocène. Cette phase d'extension prenant place dans le contexte de la collision Eurasie-Afrique a créé des structures complexes dans une...
The north Ligurian margin is a stretched continental margin located at the junction of the Western Mediterranean Sea and the Alpine belt. The back-arc Ligurian basin opened from late Oligocene to early Miocene, as a result of the Apulian slab rollback. It has then evolved next to the active Alpine orogen, in a regional compressional setting...
The north Ligurian margin is a stretched continental margin located at the junction of the Western Mediterranean Sea and the Alpine belt. This region underwent several phases of contrasting deformation styles. The Ligurian basin opened from late Oligocene to early Miocene times, as a result of a back-arc extension induced by the rollback of the...
The first leg of the SEFASILS cruise took place in November 2018 onboard the RV Pourquoi-Pas ?Up-to-date multichannel and wide-angle seismic data were acquired offshore Monaco, from margin to basin, aiming at providing a renewed vision of the complex North Ligurian backarc system. The compressive and extensive tectonic phases that have closely...
New geophysical data collected at the Aden‐Owen‐Carlsberg (AOC) triple junction between the Arabia, India, and Somalia plates are combined with all available magnetic data across the Gulf of Aden to determine the detailed Arabia‐Somalia plate kinematics over the past 20 Myr. We reconstruct the history of opening of the Gulf of Aden, including...

The north Ligurian margin is a complex geological area on many accounts. It has witnessed several phases of highly contrasting deformation styles, at crustal scale and through shallow cover tectonics, simultaneously or in quick succession, and with significant spatial variability. This complex interplay is mirrored in intricate structures that...
Geophysical and geological data from the North Mozambique Channel acquired during the 2020–2021 SISMAORE oceanographic cruise reveal a corridor of recent volcanic and tectonic features 200 km wide and 600 km long within and north of Comoros Archipelago. Here we identify and describe two major submarine tectono-volcanic fields: the N'Droundé...
A new geophysical and geological dataset, acquired during the SISMAORE oceanographic campaign (2020-2021), reveals a recent tectonic and volcanic deformation distributed over 130km in the abyssal plain that permit to unravel the unconstrained lithospheric plate boundaries between Lwandle and Somalia blocks and the controversial origin of the...
