| 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... |

| Within the French 'Margins' Programme (Groupement de Recherches 'Marges', or 'GDR Marges'), The Gulf of Lions was selected as a key area where scientists specialized in complementary aspects of geosciences (structural geology, tectonics, stratigraphy, sedimentology, various aspects of modeling) work together in order to better understand the processes that control the formation and evolution of continental margins. A key objective was to link offshore data (that mainly consist of seismic data and few wells) and onshore studies (mainly based on well and field data). This special edition of Marine and Petroleum Geology on the Gulf of Lions presents some of the main results obtained during three years of research by the group 'GDR Marges-Golfe du Lion'. |

| The Messinian erosional surface that can be observed on the Mediterranean margins is a good marker of the relative lowering of the sea level which happened during the Messinian salinity crisis. The estimate of the volume of Miocene sediments on the Gulf of Lion platform gives a minimum eroded volume of 5 300 Km . The eroded layer reaches one kilometre in numerous places (Figures 2 and 3). This volume demonstrates the erosion of the continental shelf in the Gulf of Lion and does not include the eroded volumes in the Rhone valley, the surroundings of the Gulf of Lion and on the slope. Thus, this minimum eroded volume is logically transferred towards the basin. |

| 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... |
