| 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... |

| On the Gulf of Lions margin, the Messinian Salinity Crisis (MSC) event led to a significant and widespread erosion of the Miocene shelf and slope. It is thus difficult nowadays to restore the morphology of the margin at the beginning of the crisis, and to study the Middle-Upper Miocene series rarely preserved from erosion. In this study, thanks to the use of multichannel seismic reflection data from the Gulf of Lions western slope, it has been possible to image the Miocene slope deposits. Interpretation of the data reveals several diachronic sediment bodies just beneath the Miocene/Pliocene boundary. These bodies are related to slope erosional-depositional complexes, underlain by erosional unconformities outlined by seismic reflector truncations. They are... |
