| The Gulf of Lion margin has been created by an Oligo-Aquitanian rifting followed by oceanic accretion in the Provencal basin during the Burdigalian. Two main periods have been detailed in this study. The Messinian event represents a clear marker (between 7 and 5.3 Ma) within the history of the basin. The study of sedimentary geometries on the margin and in the deep basin gave new elements for the understanding of the messinian crisis: The first element is the identification of a thick detritic series (up to 1000 m) at the transition between the sub aerially eroded shelf and the slope. The base of this series corresponds to the very first event of the Messinian crisis. The second important element is the identification of a thick stratum of lower... |

| 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... |

| Though the late Miocene "Messinian Salinity Crisis" has been intensely researched along the circum- Mediterranean basins, few studies have focused on the central part of the Mediterranean Basin and, especially, the pre-salt deposits. Within the Western Mediterranean, the Gulf of Lion is exceptional in that its sedimentary strata have not been significantly deformed. In addition, the Gulf of Lion is characterized by a relatively constant subsidence with continuous accommodation space for sediment accumulation. This configuration, together with the availability of a wealth of offshore information (seismic profiles, boreholes), enables us to precisely describe the sedimentary geometries on the margin and in the central basin. This study gives new elements for... |
