Full textClimate and tectonic factors are the main ones that control the lacustrine sedimentation. Climatic variations are marked in the sedimentation by different vegetal and fauna associations, and different lithologies. Tectonic variations control the structuration of the basin, and influence the stromatolites repartition. The marls and limestones display deposition cycles, due to periodic climatic changes, like alternations of more or less humid periods. Associated stromatolites present various shapes, made of vegetal and fauna associations, and depending on their growth environment. The detail of their internal structure reveals the recording of chemical variations of the water, happening during the climatic changes. The calculations made on their speed of growth indicate that this one is fast and discontinuous. Stromatolites associations in the lacustrine environment can form plurimetrical built complexes, which record the evolution of the subsidence through time

Full textThis survey presents a synthesis of the results on the general subject of the history of the land use from the Iron Age to the late Antiquity on a given area of the Puy-de-Dôme department (one of the administrative divisions of France) : the Limagne des buttes. Data, either already available ones or those collected while prospecting-surveying in this micro-région have been studied in order to try to fill an historiographical gap over a rural area and its land use from the ninth century B. C. To the early eighth century A. D. This study's aim is to propose an attempt of model of the population evolution in the country on the southern part of the Grande Limagne in the Auvergne and in the Bourbonnais, and this from documentation which is mainly archeological, but also based on the perusal of textual and cartographical sources, as well as all the paleoenvironnemental date available

Full textThis thesis presents the results of a multi-proxy geoarchaeological study of how anthropogenic forces and climate have shaped the evolution of the landscapes of the plateau of Corent (Auvergne, France) from the Neolithic to Roman period. A detailed geomorphological map of the study area was constructed based on LiDAR data and fieldwork. Two areas were selected for geoarchaeological analysis: i) the Lac du Puy, a small pond located within the archaeological site of the plateau of Corent, and ii) la Narse de la Sauvetat, a larger hydromorphic basin in the calcareous lowlands, at the foot of the southwestern slopes of the plateau.Geoarchaeological survey in the Lac du Puy revealed an expansive group of over one thousand storage pits, dating from the Hallstatt period. The results of fieldwork permitted the construction of a chrono-stratigraphic framework and allowed a reconstruction of the main phases of the hydro-morpho-sedimentary and pedological evolution of the basin. Multi-proxy geoarchaeological analysis of sedimentary cores provided additional information concerning palaeoenvironmental evolution of the Lac du Puy. Anthropogenic impact is clearly discernable throughout five millennia starting in the Neolithic, and is identified as the main driver of the palaeoenvironmental evolution of the basin until its final destruction by human activity.In the lowlands, geomorphological analysis of la Narse de la Sauvetat revealed that the hydromorphic basin is the result of the closure of a palaeovalley by a massive landslide issuing from the southwestern slopes of the Puy de Corent. Geomorphological and stratigraphic evidence indicates that the isolation of the basin likely occurred at the beginning of the Subboreal. Lithostratigraphic analysis was used to reconstruct the main phases of the evolution of the basin from its initial alluvial phase in the late Pleistocene, through to its hydromorphic and palustrine dynamics from the late Neolithic, highlighting the strong palaeoenvironmental potential of its sedimentary record. Multi-proxy geoarchaeological analysis of three sedimentary cores from the basin, combined with results of external malacological analysis, allowed a reconstruction of the palaeoenvironmental evolution of the basin from the late Neolithic to the early Middle Ages.Results obtained from the Lac du Puy and La Narse de la Sauvetat were integrated into the broader morpho-sedimentary system of the plateau and its margins for the period between 3000 BC and 1 AD. The geographic and temporal perspective was then further enlarged through comparison with temperate Western Europe data. The evolution of the socio-environmental system of Corent and southern Limagne was analysed in detail for the first millennium BC. Finally the role of proto-urbanization processes in the forcing of morpho-sedimentary systems is examined, marking their entry into the anthropocene

Full textThe palaeoenvironment dynamics of the upper watershed of the Garonne river have been established from the end of the glacial times until the present-day on the basis of palynologicval, sedimentological and isotopical analysis. During the pleniwurm, the regional vegetation consisted of a steppe with poaceae. The two cold episodes suggested by the fall of delta 18 0 slightly before 1750+ -300 bp and between 15800+ -270 bp and 15100+ -300 bp are the equivalent of the cold episodes recorded in the oceans around 18000 bp and 15000 bp. During the oldest dryas, between 15100+ -300 bp and 13490+ -220 bp, a steppe with artemisia established itself locally, as a result of a climate warming, also suggested by higher delta 18 0 values. The beginning of the bolling was characterised by the establishment of a sparse woodland with betula and a bushland with juniperus. During the lateglacial interstadial, the notable increase of the delta 18 0 and the delta 13 c suggests markedly warmer climatic conditions. At the beginning of the holocene, a medio-european type oak forest penetrated with corylus and ulmus established itself. The atlantic was characterized by the expansion of an oak forest with tilia

Full textTo think about populating, one must take into consideration the notion of territory. This study is based on geomorphology and applied geophysics with an approach of an archaeological settlement at local and regional scale. We have tried to establish the evolution of the interaction between these societies, their environments and what have been built in process of time. To focus on this relationship, we chose two distinct geographical areas: the desert of the Agriate (France, Haute-Corse, 2B) and the lower valley of the Taravo (France, Corse du Sud, 2A). These two areas represent a different geographical context. The first one is characterised by a mineral/rocky and hilly landscape that presents at first sight a few agro-pastoral potential ; the second one, on the other side, shows much vegetal, animal and raw material potential. A methodology of study has been put in place and was enable to fit to the features of the land. The technics used were electrics and electromagnetics methods with mechanical boreholes and geological observations which brought us the following results. For the oriental side of the desert of the Agriate : _the repetition of periods of erosion and then stabilization of soils, related to charcoal flows, suggests a rhythmic evolution of the catchment area, associated with populating phases, the importance of the anthropization, even if it is difficult to evaluate, is still an essential problematic of this study. For the lower valley of the Taravo : the cuts and the electromagnetic prospectings allow a precise visualization of the spatial distribution of the sediment, _different morphological phases for ancient periods have been brought to light, the pond of Caniccia shows a relation between the morphological evolution and human occupation,privileged areas for archaeological research have been delimited. The prospects studies involve : a complementary geomorphological study in the desert of the Agriate and of the Nebbiu, with a participation to archaeological excavations,pluridisciplinary rospectings-inventories (archaeological and geomorphological) in the lower valley of the Taravo, new mechanical boreholes in the floodplain and in the pond of Caniccia, comparison with others valleys of Corsica, comparison with others island of the Meterranean sea

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
