| The observations carried out during the "Cyaligure" submersible cruise emphasize the shaping action of the submarine currents and slidings during the Quaternary. The canyons located off the french Riviera (Provence), cut in late Oligocene detrital formations, have been the locus of several phases of in-filling, lithification and cutting phenomena throughout the Messinian epoch up to now. Consequently they can be considered as complex polygenetic structures. The canyons located off SW Corsica appear to be directly cut, in their upper course either in the cristalline basement or in volcanic lava formations. In their median part, they are cut in quaternary sediments and in their lower part in middle or late Miocene sedimentary units. The strong linear NW-SE... |

| The study of seismic profiles (made with Sparker and with air-gun) recorded in the Alboran sea helps us to complete and modify an interpretation which was previously made. Further to complementary data on the structural frame, we showed the existence of a salt layer topped with evaporites, in the basins situated on both sides of the Alboran ridges. With regard to the thick infra-salt layer in the western Alboran basin, it appears that the basement of the basin, as a whole, is at a depth similar to the depth of the North-African basin. This supports the hypothesis of a common origin and evolution for both basins. [NOT CONTROLLED OCR] |
