| 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] |

| The evolution of the sedimentary regime that prevailed on the Armorican margin from Late Cretaceous to late Tertiary is herein discussed and interpreted. The sedimentation budget of four components of the sediment : calcium carbonate, quartz, "less than 10 m non carbonate material,"and biogenic silica are quantified as is the composition of the coarse fraction and the textural properties of the sediment. Variation of the coarse fraction components is directly related to change in the oceanic environment (terrigenous supplies, productivity, calcium carbonate dissolution). Sediment texture is a function of many factors, comprising lithology, dissolution action, and hydrodynamic control. The medians of the silt fractions from bulk and decalcified sediments... |
