| 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 results of 14 aives made with the submersible Cyana in the lower parts of the Stoechades and Saint-Tropez canyons, between 2,400 and 1,500 m, are compatible with the following geological history of the French Mediterranean margin: a thick terrigeneous sedimentary series was deposited near the Oligo-Miocene transition; the canyons were eroded subaerially within this series during the Messinian; the morphology of the canyons has been maintained since by active bottom currents and gravity tectonics on the bordering cliffS.
