| The continental shelf of the "Golfe du Lion" (Gulf of Lions) has been considered for a long time as a privileged place for the study of passive margins. However, the model usually adopted to explain the formation of this type of margin does not apparently fit the subsidence history of the Gulf of Lions. Indeed, the evolution of this basin is characterized by a high subsidence rate, comparable to those of Atlantic margins, although it is only 30 MY old. Previous studies show anomalies in subsidence rate in the Gulf of Lions (Bessis and Burrus, 1986; Bessis, 1984). Seismic data from a dense grid of seismic reflection profiles acquired by the petroleum industry (RM96, LIGO and HR Total profiles) and by IFREMER (Marion and Calmar campaigns) provided by the... |

| Morphological sills condition sedimentary, water and fauna exchanges between different domains. In particular, sills are crucial factors to consider during the Messinian Salinity Crisis (MSC) palaeogeographic evolution (5.97–5.33 Ma) of the NW Mediterranean area. Here we focus on the Ebro River and its up to now unexplained short Messinian onshore length (~100 km) compared to that of the Messinian Rhone River (~480 km) despite similar present-day drainage basins. Thanks to an extensive seismic and borehole dataset, we present a new interpretation of a complete 270 km long Messinian Ebro incised-valley system course underneath the present-day continental margin and bathyal basin and its related distal detrital deposits. These results favour a syn-MSC or... |
