Full textThis theses deals with the attainments of magdalenian, epipaleolithics and mesolithics settlements during the Tardiglacial period in both Savoie and southern Jura. This essay presents, first, a statement of the attainments published at the end of ancient excavations then it develops the pluridiscinary results of the author's personal excavations achieved in four prehistorics places in both Savoie. The author analysis the chrono-industrial data to each culture in their natural environnment, that is to say synchronised with their paleoenvironnment vegetal and animal. A chrono-cultural schema of all the places of the study is proposed to be used as a bases for further discussions with researchers concerned with those cultures

Full textThe Pyrenees form a mid-latitude, intermediate altitude mountain range displaying weak tectonic activity and a westward gradient of increasing topographic inheritance from the work of Pleistocene glaciers. This thesis aims to characterize and to quantify the influence of the glacial and non-glacial erosive processes on the most elevated areas of the mountain range, during the last climatic cycle (~100 ka), according to an E-W transect from the Carlit to the Maladeta, via the Ariège. The Holocene tills volumes (Maladeta) were quantified from DEM- and GIS-derived measurements, while the lowering of the glaciated and unglaciated surfaces was determined from cosmogenic nuclides (CN). Denudation was measured through TCN concentrations in alluvial sediment in elevated catchments. Würmian denudation on supraglacial ridges (10–25 mm/ka) was slower than on cirque floors (30–40 mm/ka), thereby resulting in an increase in topographic relief. Denudation of the cirques floor increases during post-Würm spatially limited glaciations (20-400 mm/ka). Small Holocene glaciers erosion in the Maladeta is 180-700 mm/ka even > 1 m/ka. These rates are noteworthy higher than bedrock and regolith plateau weathering (2.60 mm/ka and 20-40 mm/ka, respectively). Postglacial catchments denudation (25-450 mm/ka) linearly increases with mean slope (r = 0.83) and then with the Pleistocene glacial inheritance of the landscape. Results confirm the atonic tectonic activity of the Pyrenees and show the influence of the glaciers and fragile meta-sedimentary lithologies on the Holocene denudation

Full textBetween the XIIIth and Xth millenniums BC, human societies of Western Europe experienced significant techno-economic and social changes. Considering lithic artifacts are the only elements available in Western France, comparative lithic technology has proved to be the best suited tool for very close scrutiny in those last Paleolithic societies. The study of late glacial lithic industries has allowed us to confirm and refine the chrono-cultural organizational model proposed those last years, shifting assemblages traditionally seen as Magdalenian to the end of the Pleistocene. This work has also identified major changes in the know-how but also more generally in the ways of living and thinking. The inclusion of these data within the European context has led to the understanding of population dynamics of the area and to the development of a reflection on the cultural and technical exchanges in Western Europe during the Late Glacial

Full textWith its southern latitude position (30 n), "the Western Chtouka region" shows the characteristics of a sub-arid environment. In the past, the western Chtouka littoral received an important flow of sandy sediments and still does toda during the successive droughts which hit the region, this aeolian action has become greathly predominant. A clear altera of the morphodynamic as thus teken place over some decades. The study of the existing dunes systems shows that dunes mov the coast towards the interior of the region. The sedimentary evolution expresses it self during the transport by a prog decreasing of the grain size, an impoverishment of the carbonate contents and a growing aeolisation of quartz grains. The study of the morphological inheritances of this coast, clarified by both the morphosedimentary analysis and a 14 c chronology, allowed us to understand the main features of the landscapes evolution from the ouljian (=Eemian) until now. Ouljian dune systems, besides the dynamic factors, the eustatic causes are at the origin of the edification of these san the western Chtouka coast. Eight dune systems have been identified, the oldest studied here being attributed to the late followed by the soltanian (=Weichselian), mellahian, and holocene systems. The formation of this post-ouljian sand depos been controlled by the sedimentation-subsidence balance. And its essentielly linked to the fluctuations of the ocean lev of morphodynamic activity which have been kept allowed us to follow more or less precisely the evolution of the palaeo-l particularly at the upper soltanian and holocene. Today, the degradation of this environment is increased by the anthrop especially since historical periods. The degradation of the argania sp. Forest is the most striking evidence of it

Full textThe Ramandils Cave is a key archeological site situated on the Mediterranean coast. The importance of this site derives not only from its geographical and chronological position, but also from the density of the artefacts left by Neandertal populations who settled there on several occasions as early as isotopic stage 5. This study concerns 29 997 lithic objects from five stratigraphical units. The industries, mainly in flint, are all small sized (< 30 mm). Although similar typical Mousterian features have been identified throughout the infill, some technological and typological variations (such as an increase in denticulates in units V and I) are discerned within the different stratigraphical units. The small size of the elements composing this assemblage is a singular characteristic which has been taken into consideration in this study. Indeed, the Ramandils Cave lithic assemblage fits within the variability of Middle Paleolithic sites, however differing by a characteristic size reduction in knapping economy, in matrix and resulting products production. How might we interpret this small size characteristic: as a purely cultural factor or as a result of circumstances ? Results show that this micro-production does appear to be predetermined. The characteristics of the lithic assemblage from Ramandils Cave give them a special status in the debate regarding the definition of micro-Mousterian and in the identification of technocomplexes geared towards micro-production. The goal of this study has been to better understand the technological and economical behaviour of Neandertal populations and provides new information to contribute to data already available concerning the variability of Middle Paleolithic lithic assemblages

Full textCulture groups' approach of the tardiglaciar period in the Middle Pyrenees was attempted through a lithic technology study based on five importants sites : Bedeilhac (Ariège), Enlène (Ariège), Labastide (Hautes-Pyrénées), La Balma de la Margineda (Andorre) and Troubat (Hautes-Pyrénées). Eight archeological levels including more than 30 000 flint pieces have been considered. Those ones are part of a time period ranging from middle (Bedeilhac, Enlene and Labastide), upper and later magdalenian (Troubat, levels 8 and 7) to azilian (Balma Margineda, levels 10 to 7 ; Troubat, level 6). Firstly, th process used has been a petrographic analysis of the vestiges. The main object was to find out the supplying sources of raw materials and the rules of material management. Secondly, the production schredules have been taken into account depending on the aims of debitage attributed to the corresponding archeological series (blades, bladelete, flake). We then tried to find out some typical behaviours by tool making through the kinds of blanks that were used and the types of raw materials that could have been selected for that purpose. Eventually, in a global view, these remarks are put back in the dynamic setting of culture groups by the end of the tardiglaciar period. Considering what those lines taught us, it is possible to highlight the paradygms which tend to associate those cultures into a probably common evolutionary process

Full textThe reconstitution of ice flows in north-western Alps during the Würm ice-surface maximum is the main scope if this study. Thanks to the acquisition of new geomorphologic observations, a consistent palaeogeographic cartography of the glacial system during the Würm Glacial Maximum has been achieved, for upstream watersheds and downstream zones, Second, the study has been applied to determine the origin of the different ice flows that have fed the piedmont lobes in the north-western Alps. To conduct this work, the use of several complementary methods has been necessary : (i) a glacio-morphologic approach allowing to define the altitude of the glacial equilibrium line; (ii) petrographic analysis of erratic boulders to identify from which watersheds they originate; (iii) and analysis of the heavy minerals contained in the fine fraction of ablation tills, to complete and confirm the petrographic analyses. The first stages of the deglaciation associated with the individualization of the flows coming from the four main systems of the Rhône, the Arve, the Isère and the Romanche valleys have been reconstructed. Lastly, a chronological approach has been conducted, in particular to date the Würm glacial maximum. It is based on the analysis of the available data and tends to expose the main trends. The obtained results provide a significant contribution to the paleogeographic reconstructions and to the study of ice flow organization during the Würm maximum. These new data/elements allow a novel interpretation of the glacial network organization in north-western Alps and questions/challenges/disputes, in particular, the traditional vision of the Rhône glacier reaching the « internal moraines complex ». Indeed, the analyses prove that the whole ices of Lyon piedmont lobe were coming from the accumulation zones of the internal part of the French northern Alps : south of the Mont-Blanc massif, Beaufortin, Tarentaise and a part of the Maurienne. In addition, they confirm the strength of the glacial systems that have filled in the big transverse valleys of the subalpine massifs and emphasise the essential role of the transverse glaciers coming from the central Alps in the feeding of the Lyon piedmont lobe. As for the feeding of Moirans lobe, the petroaraphic analvses and the counting of heavy minerals demonstrate a major contribution of the Romanche glacier. The study of the deglaciation stages highlights the relative significance of the different systems. In particular, it shows the pridominnace influence of the Isère glacier and the significance of which being often undervalued by authors. Lastly, a chronologic approach has been undertaken. Although it does not provides decisive new information, it suggests a diachronism between the extension of the systems of the northern Alps (late minimum) and of the western Alps (early maximum)

Full textA 2 m profile of intramoraimc organic sediments was cored from the Evian high plateau. Pollen, plant macrofossils and insect remains were used to reconstruct the local palaeoenvironment, which may be compared with a mire surrounded by a dense Abies /Pvsa mixed forest. Moreover, the use of pollen and macrofossil data led necessarily to attribute this peat layer to the final Eemian. Pollen and radiometric analyses of four palaeolacustrine profiles have allowed us to reconstruct vegetation dynamics since the last ice retreat. According to palynostratigraphic and radiocarbon data, the last degladation would have occurred prior to the L. GM Isotopic and magnetic analyses have evidenced some climatic variability during the Lateglacial that had some impact on vegetation dynamics. Accordingly to the geomorphological context of the area, these new data indicate that the Wiirmian maximum of the Rhone glacier might have occurred earlier than assumed, and prior to the Last Glacial Maximum

Eleven pollen diagrams established by 1165 pollen spectra and supported by 64 14C datings make it possible to reconstitute the Late Glacial and Holocene vegetation history. Durind the Late Glacial interstadial the forest recolonisation begin with the Pinus developpement, without the Betula phase. Picea begin to expend from the refuges. After an Younger Dryas well marked, the Holocene begin with the Betula, Ulmus and Picea expansion, then, at about 9,000 BP, by that of Fraxinus, Quercus and Tilia. Corylus optimum is correlated with the Atlantic chronozone (after 8,000 BP), that of Carpinus is characteristic of Subboreal (at about 5,000 BP). The forests of Fagus are spread starting from 4,000 BP. The first evidences of cultivation of cereals appear around 6,500 B. P. The regional diachronisms evidences makes it possible to reconstitute the migration routes of some forest taxa

Full textThe rhône valley was always a major route for humans between northern europe and mediterranean sea. Located in its middle part, the southern ardèche preserves remains of this activity. The saint-remèze plateau and ardèche canyon offered shelters and resources to the populations which lived since 350 ka. Caves and rock shelters are traps which allowed to preserve sediments and archaeological remains the study of their contents is essential to restore environment and the climate contemporary with human occupations. Sedimentological and micromorphological analyses of colombier filling and its environmental sediments allowed to find the deposit and postdepositionnal conditions. The site is located at the outflow of karstic network. Its functionning is attested by sandy silts of lower part. These deposit were drained by water from labastide-de-virac basin. When fluvial dynamic stopped, collapse of the cave resulted from the rock shelter formation. The site became suitable for the installation of humans. They will occupy nine times this place between 14,5 ka to 11 ka bp. The sedimentation of the upper part was then conditionned by climate. Analyse of these deposits showed the succession of climatic variations which has affected environment during lateglacial. The correlation of our results with the curves of palaeotemperatures validates our interpretations and the regional dimension of this palaeoclimatic and palaenvironmental framework

Full textSince its discovery in the French Pyrenees at the end of 19th century, the Azilien has an important role in construction and reconnaissance of the last Palaeolithic societies. It was characterized by its specific lithic industry (baked points), osseous artefacts (harpoons) and artistic remains (painted pebbles). However, new discoveries shed some new light on the character and dynamics of Azilian. This work deals with lithic industry in order to question its regional character and its relation other chrono-cultural data. Six lithic assemblages were examined in this work: Rhodes II (Ariège), Troubat (Hautes-Pyrénées), La Tourasse (Haute-Garonne), Le Poeymaü (Pyrénées-Atlantiques), Gouërris (Haute-Garonne) and Pagès (Lot). Primary, this study allows questioning the evolution of Azilian culture and its relation to the development of Laborien. Further, we question the character of Pyrenean Azilian, its status and particularity by comparing it with its northern counterparts. Finally, we’re observing the Azilian phenomenon in larger perspective by comparing the French facies with those of Western Europe. The development of Azilian in the Pyrenees differs from the situation observed in the “azilianisation phase” of the northern sites as the Magdalenian persist until 14 200 cal. BP and the transitional phase is actually lacking. However, during the younger phase some common traits are identified on the larger territory (France, Pyrenees, Cantabria) marked in particularly by a technological simplification. Still, the Pyrenean Azilian (between 14 200 and 12 500 cal BP) preserves its regional particularity as seen in its lithic industry characterized by double backed points, little scrapers and use of anvil in percussion. The Laborian, sporadically present in the Pyrenees, might indicate the retour of “technological normalisation” characterized by more regular and straight production. This “technical renewal” will soon characterize the whole Western Europe around 12 300 cal. BP

Full textAnalysis of human societies and horse populations interactions is viewed in the Western Europe Late Glacial context, an unstable climatic and environnemental period. The diversity of equids have been realised toward three areas : the Paris Basin, the Switzerland Plateau, and the Charente. The usual morphometrics analysis of several anatornical parts come out onto a regional pattern of horse populations, distinct of the specific reference, Equus caballus arcelini, Guadelli 1991. The distribution areas fragmentation imply a low level of genetic flux between them, a high démographie density and the absence of large scale migrations. On the other hand, it could be pointed out that all those horses evolved in the same kind of habitats (lowland meadows, river banks, marshes). The analysis of the equids exploitation allow to understand the socio-economic features of Paris Basin's Madgalenian and early Azilian bands, helped by a comparative study of Switzerland Plateau Magdalenians. In those areas, the evidence of large butchery sites show a year round exploitation of horse harems, killed during collective hunts. Conversely, in the reindeer dominated sites, horses have been obtained by less ambitious hunts. The "functionnal complementary" model of Madgalenian sites seems to be the more probable, despite the radiocarbon plateau chronological uncertainties. In the early Azilian case, the exploitation strategies are distinguished by less efficient but repeted approach or chase hunts, at différent seasons. The probable coexistence of those two Paris Basin cultural entities could have been possible thanks to the large horse populations presence

Full textDenudation is a key parameter controlling the formation and evolution of landforms across the Earth's surface. The interaction between surface processes (namely denudation) and climatic variations at the geological time scale is a highly debated issue, due to the lack of continuous sedimentary records unaffected by tectonic forcing. In order to constrain this interaction, this thesis focuses on the Var watershed (French Maritime Alps) and on its sedimentary archive which allow to track the variations of denudation rates from the present until 75 000 years ago. This period covers the end of the last glacial cycle (the Würm) as well as the transition to the current climatic period (the Holocene). The measurement of 10Be (cosmogenic isotope) in sediments allows the quantification of denudation rates integrated over the entire watershed. This method, applied to present-day sediments of the Var, constrained the current denudation rate of the Var catchment at 0.24 ± 0.04 mm yr-1. The same method was then applied to samples from two sedimentary cores constituting a continuous and high-resolution sedimentary archive of past Var sediments. The results show that the Last Glacial Maximum glaciers' advance (between 19 000 and 26 500 years) induced a significant increase on denudation (~ × 2), whereas during the previous glacial stages (between 26 500 and 75 000 years), the denudation was steady and similar to present-day value. This nonlinear response of denudation to climate change suggests the existence of a threshold controlled by the erosive dynamics of glaciers, which was close to ~ 2 mm yr-1 during the Last Glacial Maximum and ~ × 4 lower between 75 000 and 26 500 years

Full textDuring the coldest periods of the Late Glacial, in alitude the development of vast colonies of marmots is to be linked with the evolution of the upper limit of the forest. Human groups (Magdalenian, Azilian and Laborien) have focused on the preferential use of this small game.From several current collections marmots, we have established two referentials for determining the age and slaughtering season. Then, the methodological tools were applied to seven archaeological series: Colomb and the Passagère (Méaudre), Olette (Lans-en-Vercors), the Freydières (Saint-Agnan-en-Vercors), Bobache (La Chapelle-en-Vercors), Jean-Pierre 1 (SaintThibaud-de-Couz), La Chênelaz (Hostiaz). Skeletochronology analysis on a sample of archaeological material has confirmed the results obtained from the referentials. This work has highlighted the preferred hunting season to the groundhog. For all archaeological series, the season of death occurs before hibernation (from late August to early October). Thus marmots were shot during the time they have in terms of the highest quality and quantity of potential resources, for both technical products (fur and fat) and for foods (fat and meat). Moreover zooarchaeological study confirms intense butchery, with a view to recovering these different products for a deferred consumption and export to lower altitude sites

Full textAlong the coast of the Tunisian Sahel, the Pleistocene littoral deposits are organized into three distinct marine formations: Douira, Rejiche and Chebba defined by Paskoff and Sanlaville (1976) and later redefined by Mahmoudi (1988) in terms of lithostratigraphic units Douira, Khniss and Réjiche. However, the chronostratigraphy, the distribution and the relationship between tectonics and eustatism during the Middle and Upper Pleistocene remained so far problematic. The present thesis offers to establish regional chronostratigraphic subdivisions by means of IRSL luminescence dating. The IRSL ages of the Pleistocene littoral deposits (marine, lagoonal and eolian) from the eastern Cap Bon peninsula, the Sahel area and Southeastern Tunisia, are ranging between 335 ka and 66 ka. They are subdivided into six units correlative with MIS 9, MIS 7, MIS 6/5, MIS 5.5, MIS 5.3/5.1 and MIS 4. These IRSL ages demonstrate that the pre-tyrrhenian littoral deposits assigned to the Douira unit belong to two distinct marine interglacial high stands correlative of MIS 9 and MIS 7. The IRSL results of the Tyrrhenian littoral deposits from eastern Tunisia (Khniss and Rejiche units), so far assigned to MIS 5.5, are consistent with a longer chronology that extends from the MIS 6/5 transition to MIS 4. The detailed tectonic analysis of fault populations and joint sets data affecting these Middle and Upper Pleistocene littoral units (MIS 9 to MIS 4) enabled to specify the tectonic regime. It also helped to ascertain the different stress tensors. The latter were classified and compared with each other according to the chronostratigraphic data. The new lithostratigraphic, chronological, sedimentological and tectonic data obtained in this thesis are then replaced in the context of the western Mediterranean basin

Full textThe evolution of the Greenland ice sheet in the future is a major societal issue, given its potential contribution to global sea level rise. The ice sheet is controlled by ice dynamics and climate conditions. Its modelling is a challenge due to the lack of data covering the whole ice sheet and the fine scale of the interaction processes between the ice sheet and the atmosphere. To improve our understanding of the role of the Greenland ice sheet in the climate system, I have first developed an inverse method to obtain appropriate initial conditions for the GRISLI ice sheet model. I then applied this procedure for coupling the MAR regional atmospheric model to GRISLI. I have shown that representing atmosphere – ice sheet interactions at fine scales is essential to avoid underestimating global sea level rise in multi-centennial future projections. Finally, I have used the same models to study the last interglacial (130 – 115 ky BP), which is a warm period during which the sea-level was 6 to 9 m higher than today. My work shows that downscaling large scale model outputs at the regional scale is required to represent climate – ice sheet interactions

Full textThis thesis proposes a multi-criterion analysis, from which have been displayed the bioclimatic characteristics of the Late-Glacial stadials and interstadials. Mapping data, mainly obtained through crossing three quantification methods, lead to the opposition of distinct paleoclimatic domains in the study area. The relative synchronism of the studied geochronologies highlights the central position of the Northern Atlantic Ocean in the determination of Late-Glacial abrupt climatic changes. However, a review of the main scenarios of oceanographic forcing identifies some of their limitations in the triggering, self-maintenance as well as the teleconnection of the climatic signal. The exploration of other physical mechanisms allows validating the hypothesis by which the air masses’dynamic is an essential component in the forcing of abrupt climatic events. However, the usual theoretical model of atmospheric circulation can not accurately reconstruct the paleoclimatic dynamic of Late-Glacial events. One of the main innovations of this thesis is therefore to experiment a general circulation model, the Mobile Polar High’s one, which provides a comprehensive explanation of climate changes by determining two distinct modes of aerologic circulation (fast and semi-fast). The advantage of this model lies in its ability to analyze a relevant diversity of paleoenvironmental changes in North America and Eurasia during the study period

Full textSolid (sS) and dissolved (dS) sediment yield (S) have been quantfied along Late Glacial and Holocene in Marais de Sarlieve catchment (France Massif Central) from the study and quantifying of carbonated lacutrine sediments. Comparaison of sS and dS with the evolution of human settlement and vegetation in the catchment permit to specify agriculture development impact on erosion. During the oldest Dryas and the beginning of Holocene, S was weak : 28 t. Km[-]². An[-1] until younger Dryas, 8t. Km-²an[-1] during Preboreal then 13 t. Km[-]². An[-1] during Boreal and the beginning of Atlantic. These variations were related to pedogenesis. During the Atlantic, P reached 61 t. Km-². An[-1], with a strong increase of sS related to first clearances. During Subboreal, affected by a more pronounced humidity, P reached 201 t. Km-². An[-1] then 238 t. Km-²an[-1] during Subbatlantic. These increases are related to conjonction of climatic and human parameters

Full textThe end of glacial time is a period of change. The succession of different vegetations and faunas from the end of Lateglacial period to the beginning of the Holocene is marked by the large range and sometimes short time climatic fluctuations. Between the XIIIth and Xth millenniums BC, human societies of Western Europe experienced also significant techno-economic and social changes. This study focuses on the evolution of Younger Dryas societies and more specifically on the transformation of lithic industries and on the palaeohistoric meaning of these changes.The lithic material of the A4 level of Rochedane rock shelter (Villars-sous-Dampjoux, Doubs, France) constitutes a first rate corpus to reflect on this issue. The study of this corpus, which integrates the technological, typological and economical aspects of lithic industry, has allowed us to confirm and refine the chrono-cultural organizational model proposed those last years by A. Thévenin. Confronting results obtained from Rochedane to those groups located in bordering regions, this work has allowed the definition of “industries de type Rochedane”. The inclusion of these data within the European context has led to the understanding of population dynamics of the area and to the development of a reflection on the cultural and technical exchanges in Western Europe during the Late Glacial. Identity of “industries de type Rochedane” is double: those industries are part of epigravettian world and of Straight Blades and Bladelets Industries
