Full textWe have analyzed of 87054 bones and teeth of the west cave at Le Portel, focusing on the geochemical conditions of preservation and fossilization. In order of importance, we have identified 21 species, among the large herbivore community Rangifer tarandus, Equus caballus germanicus, Bison priscus, Cervus elaphus, Capreolus capreolus, Capra pyrenaica, Rupicapra rupicapra, Megaloceros giganteus, Coelodonta antiquitatis, Mammuthus primigenius, Sus scrofa (large herbivore community) and Canis lupus, Vulpes vulpes, Crocuta crocuta spelaea, Ursus spelaeus, Meles mels, Martes martes, Mustela putorius, Panthera (leo) spelaea, Lynx lynx, Felix sylvestris. It is possible to predict that the environmental conditions under which the large mammal community existed was an arcticor cold open biotope (steppe,toundra). The archaezoological analysis provide data on the hunting strategies and reveal an opportunistic behavior of the neandertal man. Nevertheless, the exploitation of the main ongulates (reindeer, horse, bison, red deer) shows a selective pattern in the hunting strategy by the sex and age composition of species samples. Le portel may have been a strategic hunting location where a multicomponent site has been formed, producing evidence for many episods of killing and butching leading to the early Wurm (upper Pleistocene, isotopic stage 6-3)

Full textThis study aims at breaking apart the mechanisms of collective action in altitude pasturing. From the diachronic point of view, it raises the question of permanencies and discontinuities in the managing of the mountains of Ariège and rests on the analysis of the standards governing the access and the use of collective altitude pastures. Based on the assumption of a deep renewal of mountain farming and pastoralism, the description of a double historical and space discontinuity in pastoral practices allows one to affirm the emergence of new relations between the breeders and altitude pastures. In spite of the apparent diversity in the ways of managing, the systems of standards of altitude pasture breeders are characterised by a remarkable homogeneity and their great coherence enables them to associate operational, social and symbolical objectives. Altitude pasturing, beyond its strict technical functions, is at the origin of complex social and identity constructions which brings it to the level of space ideology

In that ununsual context, most of that councils experienced some difficulties and composition changes. The legislative framework underwent many transformations and the municipal council member attitudes varied depending on the cases during the Occupation. At the Liberation, new disruptions affected these councils with, among others, the appearance of Liberation Local Committee. 1945 and 1947 Municipal elections saw the accession to power of political majorities directly sprung from the Resistance

Full textOur objective is to understand what is the part of individual choice in change ; how does an individual select between many possibilities and act to modify his positions when one part of his whole activities is interfered with. It it is also to understand the role of social interactions in the choices individually. Made. As our basis we have taken the theory of "activities system" (cnrs 259) to show that when the subject adopts a strategy (choice of organizing his activities in such a way as to respond to the disturbance and to build a new equilibrium) this is his "model if living" which intervenes because it constitutes taking a stand in relation to practices conflicts (modern traditional). The results obtained through statistical computation questionnaire send to 80 breeders allow us to say that : - it is by the interpersonal exchanges (coopera- tive or conflict ridden) that the subject manages to take a stand in relation to pratices conflicts and transforms his "model of living" ; - this taking a stand is made easier, is speeded up by some interactive situations produced in the midst of the "local professional group" (j. P. Darre) ; - it is according to the sens he gives to the innovation that the subject make an effort or not of his "appropriation". So the innovation can't be perceived as a simple process of adaptation and, because it arouse an activity of "intersignification", the technical change can no longer be studied independantly of the others

Full textThe catalan forge was born and was perfected during the XVIIth century in the Foix county and in the East of the Pyrenees. This ironworks is a major technical innovation to be seen in the context of a long fidelity to the direct smelting of iron ore. At the origin of an iron industry, it has a higher output of recognizable metal (fer mol, fer fort, acier naturel), saving charcoal at the same time. The quick diffusion of this inventionon both sides of the Pyrenees and the systematic appeal to Ariege ironworkers show that it answers metal processing methods appropriately, with costs compatible with the rural society finances, bearable for the mountain environment, acceptable for the mountain communities in the traditionla agro-pastoral civilization and finally closely connected with the regional market demands belonging to Toulouse. This forge allowed mountain people getting always more numerous to survive in the high valleys. The catalan forge disappeared at the end of the XIXth century (to be more precise in 1884), while pyrenean society undrewent a radical transformation

Full textAfter a historic piecing together of floods and catastrophic torrentiality in the ariege catchment, this study is trying to establish its connections with regional development. In spite of a hazard though historically proved, we are faced with the non-development of the valley. Although attempts have been made, principally in the second part of the 19th century, none has succeeded. All the more so since the disaster did not seem to be noticed after 1920. Successfull during the last century and still recently, the anthropocentric hypothesis, according to which mankind was held responsible for floods and torrentials disturbances, seemed to make sense here. Nevertheless temporarily, both, in an environmental context of desertion and return to "natural" harmony, the recurrence of great floods from 1950's make us doubt about the original issue. Since obviously the anthropic implication was not fully satisfactory, anbother hypothesis was essential, in relation with climatic fluctuations. Indeed, faced with with the steadiness of anthropic pression over environment up to 1950, or at least of its ecological expression, the rythmic dynamics of floods since the 18th century can easily be applied to this thesis. Finally, beyond the question of nowadays development in an environment with hazards, no doubt it is the issue about discontinuities of naturals environments evolution wich is our new concern
Boutin, Alexandre. "Etude des conditions de formations du gisement de talc-chlorite de Trimouns (Ariège, France)." Thesis, Toulouse 3, 2016. http://www.theses.fr/2016TOU30158/document.
Full textThe Trimouns talc-chlorite deposit is located in the north Pyrenean Saint Barthelemy massif (Ariège, France). This deposit is remarkable in its minerals' quality and quantity as well as for its strategic position in the Pyrenees geological history. This study aims at understanding the formation conditions of the talc-chlorite deposit and at integrating them in the alpine pre-orogenic context. To this, we focus on three main themes : 1) Using geological and structural mapping studies, we describe the rocks and their organization as to estimate how much variscan and alpine orogenies affected them. 2) With thermometric analyses using different methods, we seek to define what is the thermal history recorded in the different units of the deposit. 3) Using in-situ dating on a wide range of minerals, we locate temporal references on various geological objects to document hydrothermal events. Achieved results demonstrate the polyphase caracteristics of the deposit, in the three focal areas used : deformation, thermal approach, and geochronology. Structural analysis shows that the mineralisation seals an other deformation, probably of the variscan period. This mineralisation is also formed in a dynamic context and then deformed as well. The thermal study highlights that mineralizations are associated with one or more cold events, and a hot thermal foot-print is preserved in the footwall and the hanging wall of the deposit. Dating results show that the formation talc and chlorite in Trimouns is multiphase, associated with succession of metasomatic events. The Albian event is the major hydrothermal event but older episodes are recorded in Jurassic at Trimouns and in Permian in other fields on the west-ern Pyrenees. The synthesis of our works allows us to propose a model of the formation of the Trimouns talc-chlorite deposit. This model is part of a post-Variscan extensive geodynamic context that can be related to the Pyrenean extensive pre-orogenic phenomena during Cretaceous period (120-85 Ma). This pre-orogenic context is associated with mantle exhumation, likely source of magnesium necessary for the formation of talc. Our studies also show that the Saint Barthelemy massif and possibly other similar north Pyrenean massif are not "simply" Variscan but have been deeply affected by the events of the Alpine cycle

Full textThe West cave of the Portel located in Ariége in the commune of Loubens has been excavated between 1949 and 1987 byJoseph and Jean Vézian. The excavators identified 20 layers spread in 4 archeologically stratified groups : the basic group, the first Mousterian group and the second Mousterian group and an ensemble of the superior Paleolithic group corresponding to the isotopic stages 5, 4, 3, beginning 2. The contents excavated from this cave gave us 34 Neanderthal human remains and more than 200 000 artifacts corresponding to the industry, the macrofauna and the microfauna. Paleontological studies have been realized on the 4495 Bovinae and Equidae remains. Environmental Paleolithic studies have been completed from 12963 remains of the macrofuna and from 896 rodents registered to this day (NMI). Bovinae paleontological studies (1486 remains) allowed identification of two genre : Bos and Bison. The diachronic and synchronic comparisons have led to determination of Bison priscus mediator and Bos primigenius primigenius. Equidae paleontological studies have allowed confirmation of the first determination: Equus caballus germanicus (Gardeisen,1998).The diachronic and synchronic comparisons with the statistical tests associated (ACP, CAH, and the test of k means)allowed to bring closer the horse from the Portel to those of the Combe Grenal (layers 1 to 35) and the horses of the Tournal cave (stages II middle and II B). Some remains found in the superior Paleolithic have been attributed to Equus caballus gallicus. This horse resembles the horses of Camiac, of Jaurens (inferior recent Würm) and of Solutré (stage of the Aurignacian). Environmental Paleolithic studies has shown, at the bottom of the contents excavated, a landscape semi open, rather temperate forest corresponding to the isotopic stage 5 (interglacial Riss-Würm and to the beginning or ancient Würm). The isotopic stage 4 is rarely represented. The principal occupation of the site by Neanderthal (F à D) is during the isotopic stage 3 characterized by very great climatic changes with a succession of Heinrich events (H4, H5) and phases of warming or cooling phases of the cycle Dansgaard-Oeschger (7, 8, 9, 10, 11, 12, 13) in a landscape very open, far reaching and vast. The layer B presents one gravettian industry and some Bos, and certainly corresponds to the phase of warming of the cycle Dansgaard-Oeschger 2

Full textThe consequences of the great crisis that resulted from the confrontation of the church and the republic are particularly grave in the Ariège region. Indeed it bore witness to a surge of political anticlericalism as well as disastrous performance in schools. The latter was caused by the secularization, and later the outlawing, of religious congregations. The factors contributed to a great decline of the influence of the clergy while religious callings were less numerous in the wake of the separation of the state and the church. The times of crisis are also characterized by an increasing disregard for Catholicism. On the era of 1914, a slight majority of women obeyed the precepts of the church whereas the male population utterly disregards them. But the contrast is great between east and west, the latter being more faithful. In order to take these challenges the bishops - his grace bishop Rougerie and then his grace bishop Izart had enough priests whose training they improved. But Rougerie's long episcopate - from 1881 to 1907 - was branded by controversies which blemished the clergy's reputation owing unruly and unevenly zealous clergymen. Although the pastoral was still centered on the mission it did evolve during this period. Under the influence of ultramontane spirituality a less stem brand of religion was offered to the faithful. The penance practice was softened and devotions centered on Christ and moral issues were advocated. They met with widespread success, especially when they were rooted in traditional stuff such as pilgrimage to local sanctuaries dedicated to the Virgin Mary. On the contrary the frequent practice of communion hardly gained ground over this period. Several factors share the responsibility of the religious setback such as the insufficient action of the clergy, the influence of " democratic radicalism " and modernity bursting in the countryside, as well as factors rooted in a more distant past but Catholicism in Ariège was still thriving in 1914. In the context of crisis a first "action catholique" was set up and the religious feeling was strongly displayed during popular devotions or during the missions

Full textFor several decades, the central Pyrenees have been the subject of multidisciplinary researches, which deal with medieval mining and metallurgical activities. In the ancient viscounty of Couserans, archaeological excavations unearthed the site of Castel-Minier, which played a major role in mining and metals production between the late 13th and 15th centuries. The artefacts uncovered have highlighted the polymetallic activities of the workshop, which is characterized by the practice of several metallurgies concerning silver, copper and its alloys and lead. Our work aims, on the one hand, to identify the nature and origin of the mineral resources that supply the site and, on the other hand, to understand the functional organisation of the different workspaces through the restitution of the chaînes opératoires.Our research is carried out in a multidisciplinary perspective, combining the study of textual and iconographic sources, the results of archaeological excavations and data from the archaeometric studies of the metallurgical artefacts. The results show, besides the transformation of argentiferous galena to extract silver, the production of desilvered lead, unalloyed copper and antimony-lead bronze, or caldarium. Each chaîne opératoire is subject to a detailed study in which technical practices are discussed, as well as the forms and qualities of production. The association of several metallurgical activities in Castel-Minier workshops is an opportunity to address the issue of workers' multi-skilling and expertise, and also to discuss their adaptability according to the mining opportunities and the expectations of the metals market

Full textTThe twelwe southwestern departements of Aquitaine sheltered from the end of the directoire an active resistance to enrollment in the army. Draft dodging was at its highest in 1798-1799 (year an VII of the revolution calendar) and from 1805 to 1807, when Napoléon gained his greatest victories ; it decreased gradually afterwards due to clever forms of repression by the authorities and did not reappear until the very end of the empire, when France was invaded. Draft dodging found a widespread support among civilians that went as far as local authorities and even some prefecture civil servants. At all levels of society, everyone had then favourite way of escaping the law : the sons of the upper class would hire a replacement, the less rich would obtain illegal exemptions, while the poorest were forced to flee from the family home without hope of return. Though the practice of replacement highlights the injustice of the whole arrangement, draft dodging hardly seems to be a reaction of the poverty stricken against the prejudices of the conscription system. It was, finally, all of society that was opposed to conscription and thus supported the draft dodgers. Faced with such opposition, the authorities reacted by mixing firmness, psychology and clemency. But the operations of garrisons and of flying columns heightened an already tense situation. The explosion of collective revolts, notably in the mountain cantons of Ariège and of Haute-Garonne recall the uprisings against the state as tax collector under the ancien regime

Full textThis thesis seeks to analyse a series of issues pertaining to social uses of folklore, traditions and rural heritage. Based on historical materials and an ethnographic fieldwork undertaken in the Couserans, a small “pays” located in the western part of the French (department of the Ariège, in the central Pyrenees), the analysis focuses on the economic and political dimensions of “policies of authenticity”, promoting local singularities. First, the thesis investigates historical issues: the genesis of social representations of this “pays”, in having a look to the part played by nineteen century’s folklorists in the institutionalisation of these images, the political uses of folklore and tradition under the Vichy gouvernment and the consequences of such uses after the Second World War. The analysis focuses then on the relations between two main aspects of contemporary process. First, I begin by describing the “rural tradition renewal” wich can be observed in this part of the Pyrenees during the 1990s. I stress on the fact that the aim of such renewal practices was the valorisation of rural heritage and the promotion of “local authenticity”. In the same time, this aim was directly integrated in contemporary public policies towards rural development, especially with the creation of new territorial development public structures, the pays, created by the “Voynet” act in 1999. After the creation of such a pays in Couserans, the use of rural heritage as a key tool for social and economic development will enhance the construction of images of authenticity and the transformation of the socio-economic functions of the territory

Full textThe Western European variscan belt is a vast metallogenic district which hosts a wide diversity of mineralizations. A large part of them have been historically exploited, such as Salau (Central Pyrenees), the most important French tungsten deposit. The field results combined with the mineralogical and geochemical studies converge to show that it exists two superimposed ore types: (1) a calcic silicates skarn with rare fine grainedscheelite and disseminated sulphides; (2) a mineralized breccia with massive sulphides (pyrrhotiteand chalcopyrite dominant), gold and abundant coarse-grained scheelite which have constituted the main part of the exploited ore. This breccia is localized in ductile-fragile shear-zones (Veronique fault) which crosscut the granodiorite. U/Pb datings on zircon, apatite and scheelite place the skarn, contemporaneous of the LaFourque intrusion at 295±2 Ma while the massive sulphides breccia was formed ca. 6 Ma later at 289±2 Ma.These mineralizations, from two successive intrusions (granodiorite then leucogranite), belong to the evolution of an Intrusion Related Deposit model. The emplacement of the high grade gold and scheelite breccia was initiated by the progressive focalization of the regional deformation in the Axial Zone of the Pyrenees within EWdextral-reverse faults. The source of gold at the Pyrenees scale could be explained in part by this type of high-grade mineralizations. The RSCM paleo-temperature map has made possible to locate other undercover intrusions, extending the mineralized district over more than 7 km until the W-Au Aurenere occurrence in Spain
