Full textPast reconstructions of the isotopic Sr composition (87Sr / 86Sr) of marine carbonate skeletons (MCS) are very widely used by chemostratigraphs and palaeoenvironmentalists because they allow to reconstruct variations of the 87Sr/86Sr ratio of the ocean across geological time. Paleoenvironmental reconstructions and chemostratigraphic dating are based on the consensus that MCS precipitate their carbonate skeletons at the isotopic equilibrium with surrounded seawater, that is considered as homogeneous at global scale due to a residence time of Sr (2 Ma) higher than the global ocean mixing duration(1600 years). Their reliability as chemostratigraphic tools can therefore be questioned, in particular because no formal evaluation of biological and environmental biases has been carried out at a global scale. This study proposes a global reassessment of the Sr isotopic composition of both MCS and seawater of coastal and oligotrophic environments. The isotopic signature of MCS and coastal water is largely influenced by continental inputs that can modify their isotopic signatures. In fact, given these heterogeneities, this study has recalculated the Sr residence time. Finally, this study propose a better understanding of the global strontium cycle at different time scale

Full textThe La Voulte Lagerstätte (Ardèche, France) is characterized by a diverse and exceptionnaly well-preserved fauna that dates back to the Lower Callovian (MiddLe Jurassic, ca 160 Myr). It is located along the western margin of the South East Basin that belongs to the Tethyan Ocean. During the Jurassic, this margin was characterizd by a complex submarine palaeotopography of tilted blocks generated by a series of faults inherited from the Hercynain tectonics. The submarine relief was steep and corresponded to a major break in the marine bottoms. The sedimentation was dominated by marls and calcareous mudstones suggesting a low energy and deep-water depositional environment. These deposits may be affected by local sedimentary slides (slumps) originating from the fault-controlled escarpment and thus confirming the strong tectonic control. These sediments are rich in fossils whose composition and quality of preservation differ in the two main localities studied here : the Chénier Ravine and the Mines Ravine where the La voulte Lagertstätte crops out. The fossils from the Chénier Ravine consist excusively of biomineralized skeletons that occurs in alternations of marls and marly limestones. The fauna is dominated by siliceous sponges (Haxactinellids : 11 species, Lithistids : 6 species) and stalked crinoids (Cyrtocrinids : 7 species). Palaeoecological comparisons with Recent representatives of the two groups indicate a deep-water palaeoenvironmental setting probably located in the bathyal zone. The fauna from the La Voulte Lagerstätte contains both numerous sideritic nodules with frequently 3D-preserved crustaceans and marly horizons rich in more or less flattened softbodied fossils. The updated faunal inventory recognizes about 60 soecies distributed within arthropods, coleoid cephalopods, marine worms, echinoderms, vertebrates, bivalves and brachiopods. The major components of the fauna are the arthropods (50 % of the species), the coleoid cephalopods (10 %) and the echinoderms (10 %). Among the arthropods, four groups dominate in numerical abundance : the Thylacocephalans (33 % of the specimens), and the Solenoceridae (23 %), the Coleiidae (16 %) and the Penaeidae (9 %) crustaceans. The composition and some anatomical features (e. G. Bioluminescent organs, hypertrophy of eyes) of thes arthropods suggest a relatively deepèwater environment characterized by dim-light conditions. The coleoid cephalopods (cirrate octopods, vampyromorph, squids, giant teuthoid squis) and other organisme described here for the first time (sea spiders, sea stars) have Recent analogues that all live in deep water niches always exceeding 200 m. The fauna as a whole bears the characteristic features (composition, adaptive features) of the present-day bathyal fauna. The la voulte Lagerstätte may be one of the rare Jurassic Lagerstätten, if not the unique, to have fossilized a deep marine fauna. It brings key-information and original data on the biodiversity of an assumed bathyal environment during the Middle Jurassic. The presence of both thick iron deposits and unusual sedimentary minerals (e. G. Galena, sphalerite, barite, celestite) may indicate hydrothermal processes (vents, cold seeps ? ), in possible relation with the activity of the La Voulte fault. The fauna from the Lagerstätte, by its composition, preservation and remarkable in situ concentration of benthic organisms shows some ressemblances with Recent faunal communities living in the vicinity of hydrothermal vents. The main difference with these present-day hydrothermal communities is the absence of characteristic sessile benthos (ex : giant bivalves, tubeworms) but the originality and the remarkable abundacne of the crustaceans reinforce the hydrothermal hypothesis. The La Voulte Lagerstätte, exceptional on several accounts, might be considered as a very particular deep-ssea possibly linked to marine hydrothermal site

Full textThe Benguela sedimentary basin was selected to revise the Albian biostratigraphy of the Angolan margin. Seven localities were thus retained, distributed along approximately 120 km from North to South. Of the 30 lithostratigraphic sections sampled, bed-by-bed, with centimetric precision, only 18 are presented in this study. An analysis of macrofaunal systematics described 91 ammonite species, including one new species. The echinofauna comprises 23 species, including nine new ones. This study of the macrofauna of the Albian in Angola comes after an absence of research lasting over half a century in the case of Echinidea and 20 years for ammonites. The study of the ammonite fauna allows the identification of 17 horizons distributed in 8 subzones correlated with the zonation of the Tethyan Province. Such a precise division is proposed for the first time for the Albian of this area

Full textThe Valanginian is characterized by a 13C positive incursion, outlining an increase in productivity that started in the Campylotoxus zone and reached its maximum in the Verrucosum zone. In order to detail the environmental changes and their chronology, this work focused on three basins located in the Tethysian domain: the Vocontian basin, the Betic basin, and the Lombardian basin. The method consisted in the study of clay assemblages, organic matter geochemistry, and paleotemperature reconstruction, based on isotopic composition analyses of belemnites. From the data gathered, a scenario is proposed. The environmental perturbations seem to begin in the Campylotoxus zone. The end of this zone is characterized by an increase in productivity and preservation of organic matter. This led to a significant cooling. Ice, permanent or not, appeared at higher paléolatitudes. Their formation triggered a sea-level fall at the Campylotoxus-Verrucosum transition, leading to higher kaolinite contents in the three domains studied. The setting-up of upwellings also contributed to organic productivity. A positive feedback loop seems to have maintained relatively cold conditions until the beginning of the Hauterivian. The production of organic matter has likely been initiated by the conjunction of several factors. There was probably an upwelling system at the beginning of the Valanginian. Also, the aerial volcanism recorded at the beginning of the Campylotoxus zone could have played a significant role in the organic production through the fertilization of oceans
