Prunet-Tricaud, Marie-Rose. "Le château d'Assier en Quercy." Paris 4, 2003. http://www.theses.fr/2003PA040101.
Full textFrom the présent stat of the château of Assier, which represents about one-tenth of the edifice built by Galiot de Genouillac between 1515 and 1540, it is difficult to have an idea of the former greatness and quality of the edifice. As captain-general of the French artillery in 1512 and François Ist great equerry in 1525, Galiot was an eminent figure at the court, whose architectural and humanistic tastes he expresses before others in Southern France. With some exceptional documents it is possible, not only to form an idea, but also to restitute very precisely the lost wings. This study is based on the analysis of the various historical documents -figurative, manuscript or printed sources- which are confronted with the remains either on-site or dispersed. It leads to the restitution of the architecture and decoration, and to the account of the influences undergone and then exerted by what was, according to Brantôme, "the most superb house one could see"

Full textThis search is about civil architecture and try to establish, for the Quercy, the chronology of the architecture's evolution from twelfth to fourteenth century. The monographic approch studies eighty-three buildings sorted with typology. The study of architecture involves the environment of the basting in the Quercy's towns, the historic context, the natural sphere, the urban frame of the cities, the human, political, economical and social sphere and the technics resources, building modes and materials in use. In front of the fiew and wretched writing witnesses and the difficulty to identify the buildings mentioned, we have elaborated a working'method fonded on the geometral drawing of the identified footprints and the graphic restitution of the initial dispositions. The global comparative of the buildings and the study of theirs organisations permit us to elabore a typology. The fiew sculpted decoration incites us to find in the drawing of the brised arches a true trace of datation. The study of theirs definitions, based on the Villard de Honnecourt'notes deciphered by Roland Bechmann (Villard de Honnecourt, La pensée technique au XIIIème siècle et sa communication, Picard, 1991), and theirs transpositions in the buildings in census, incite to look after the proportions in use during each stylistic period. The confrontation of mark known with the identitied periods and the evolution of the architectures'shapes permit to elaborate a complete chronology. Comparisions with civils buildings outside the quercy permit to appreciate the originality of the region and to refine the bonds and the exchanges during every periods

Full textThe aim of this study is to question the link between material productions and cultural identities of Neolithic communities through the example of the Middle Neolithic Southern Chassey culture and of its ceramics. The first chapter summarizes, in a historical perspective, the different meanings given to the stylistic characteristics of the Chassey ceramic productions and the means of their recognition. In a second chapter, the monographic study of four previously unpublished sites, Capdenac-le-Haut, Roucadour, la Perte du Cros et le Noyer (Lot, France), allows to establish stratigraphic sequences documenting the local evolution of the ceramic productions. It is then possible, in the two last parts, to analyse in details the stylistic variability of those productions in a chronological and geographical context perfectly controlled and to put into evidence the complexity of the parameters working out the ceramic style. Those results lead to wonder the cultural and social mechanisms structuring the Neolithic societies

Full textA local and political newspaper's story and evolution, contents and shape's study. "l'Essor du Quercy" (december 1965 -august 1974), born in french town of Cahors (Lot), has been published for one year when its foreign origin was obviousness: the another newspaper "l'essor du Limousin", born in town of Limoges (Haute-Vienne). Informatique in both "essor" was politized by less gaullist ideology than political ambitions. Under direction of the prime minister Georges Pompidou, and his political "friends" (Jacques Chirac, Jean Charbonnel and Bernard Pons), these newspapers were used for government's propaganda and for politician's support during electioneering. In spite of endeavours to publish also other kind of news, "l'Essor du Quercy" could not become a real newspaper. That is the final result of the research

Full textOnce at the heart of the French Republic, Quercy remains a land where political vocations seem to be inherited. This lineage phenomenon is to be found, particularly, in rural areas with a strong centre-left to centre-right resonance. The political sphere and the weight of dynasty and traditions, still much in force in those lands,play a great part in keeping male domination vivid. Under such a sociological yoke, women still manage to find free shelters. Some prefer to get away geographically or symbolically, others strive to exist within the political field. Yet, whatever the roundabout way considered, all the women in the shadows belonging to the political lineages of Quercy are observed to exist for themselves. They do not put it in words,they do not claim it, they simply move on silently,silently necessarily, towards a few areas of freedom. There, more than in any other sociological fields, wives contribute to their husbands'success. The political path punctuated with elections, electoral campaigns, permanent questioning, verbal battle and doubt, weakens elected representatives. Women, their women, listen to them, back them,reassure and keep them under control, and strengthen their skills. To achieve this goal, they expend boundless abnegation in laying groundwork and in creating numerous as well as varied networks. The women in the shadows, in the political lineages of the Quercy region, are not just the "wives of. . . "-sitting there and looking pretty-exhibited by representatives anxious to secure their power of attraction, or simply settled in the "pillow-talk administration". On the contrary, in some cases,the position of the women in the shadows might almost be similar to a gynecocracy in actual fact. Such a model is timeless and might be set as an example
Czerniak, Virginie. "La peinture murale médiévale en Quercy : (XIIe-XVIe siècle)." Bordeaux 3, 2004. http://www.theses.fr/2004BOR30053.
Full textIn the northerly limits of lands from the Languedoc, Quercy, which geographically becomes confused with the primitive diocese of Cahors, belongs until XIIIth century to the sphere of influence of the house comtale of Toulouse. This position of border made of Quercy a crossroads widely opened to the influences stylistic as shows the pictorial production of it, rich in fifty sets - among which unpublished 28 % - preserved as well in the religious buildings as the civilians. This study revealed a pictorial tradition of seven centuries, since the vestiges of decoration painted by a Carolingian altar until the whole second quarter of the XVIth century which still recover from the medieval sphere. The cathedral of Cahors testifies to her only of the importance granted to the colour with a pictorial campaign realized in the 1300s, which concerned the totality of the building, up to the outside portal. If the Romanic pictorial production translates the artistic exchanges to which the country was opened, the paintings of the XIIIth and XIVth centuries underline an one-sided northerly influence whereas the decorations of the end of the Middle Age betray, by their stylistic disparity, the impulse of creation aroused by the interruption of the French-English conflict to which Quercy was particularly exposed

Full textAt the end of the « Ancien Regime » the mas (sive village) is the elementary territorial unit in the northeast of the Quercy province. Men in their estate are living from traditional farming. They suffer heavy taxes from the encompassing powers, the monarchy and the ecclesiastical lords. The thesis studies the behavior of the population in front of the different tax levies, property taxes, private incomes, tithes. As maps are not used at that time, the two types of archive documents for land registers, the « compoix » and the lord « terriers », are analyzed by an original method, using geographical referenced graphs. The soil and the human being are represented in geographic, agrarian and social networks. The research focuses on the communities of inhabitants confronted by the growing monarchic state. Consuls designed annually by the farmer's assemblies have the thankless task to collect the royal taxes, the « taille ». On another side the lords, using their property rights known as the « complexum feudale » takes off foodstuffs from the harvests. The church also plays a central role in that society where the beginning of the XVIIth century protestantism is still present. A large demographic corpus allows the study of that endogamous population which practices an unequal inheritance system. The land constitutes the only long term wealth and so directs the social reproduction strategy. The thesis considers how following the individualism growth, the rise of the population, the matrimonial diffusion, the society progressively becomes, on one side, free from the lord domination and on the other side, dutiful to the state power

Full textBetween 29,000 and 7,000 cal. BP Quercy has recorded several human occupations throughout various climatic contexts from the beginning of the Last Glacial Maximum (He3 event) to the Holocene climatic optimum. From the Middle Gravettian to the end of the 2nd Mesolithic hunter-gatherers implemented different techno-economic strategies in the acquisition and use of chert. To clarify these choices, the petroarchaeological study of the collected cherts reaches for a better understanding of the spaces travelled by the Prehistoric people. It allows us to highlight possible interactions between groups at medium or long distance and to assess the variability of occupations in the synchronic approach. In the diachronic approach, this work enables us to better comprehend the trends and the variations of these techno-economic behaviours in light of environmental evolutions.The analysis of the lithic assemblages from twelve occupations and the comparative review of fourteen sites of Quercy area and its margins allows us to characterize the litho-spaces variability and to highlight the extension/contraction phenomenon of the acquisition territories. The results make it possible to emphasize the differences between the north (Dordogne valley) and the south of Quercy (Lot and Aveyron valleys) and to perceive more precisely the territorial contraction process beginning at the end of the Upper Pleistocene and fully expressed during the Mesolithic. A reflection on the major lithological tracers also enables us to perceive probable long-distance connections with other geographical areas (Gascony, Charente, Center) at key moments of the Upper Paleolithic

Full textDuring the papacy of Avignon, so most cardinals are buried either in the pontifical city, or in their country of origin, some of them choose contrary to founding in their place of origin not only one religious community but also of the buildings to accommodate their tomb. They imitate in that the successive popes, in particular Clement V and Clement VI. In parallel, develops at the 14th century, under the impulse of John XXII, the creation of secular collegial news in the South of France.Pierre des Prés (1280-1361), quercynois, is a close relation of John XXII. Lawyer, it gains the confidence of the pope who created it cardinal in 1321, then invests it in 1325 load of vice-chancellor of the Church. The first part of this work is devoted to a biography of this character and also shows his desire to socially raise the members of its family.The cardinal des Prés is also, just like of other cardinals among his contemporaries, the founder of a religious community, charged to take care on his skin. If it chose secular canons, others privileged the orders Beggars. These is the choice which is examined and studied in the second part. To shelter these monks, Pierre des Prés made build a church in his native village, Montpezat-of-Quercy. Classified with the title as of Historic buildings by 1840, this building proved little known. Our study replaces collegial church Saint Martin in her context of construction, between 1337 and 1343, but also presents the materials used, the techniques employed, the job management and the men who have work on the project. Lastly, the last part tackles the question of the memory of the cardinal, built thanks to his tomb and with the many objects offered by him to its collegial chapter. Thanks to the latter, the memory of Pierre des Prés was transmitted of century in century, thus agreeing with the worms of Pétrarque: the fame overcomes death

Full textRiversleigh, World Heritage Property, located in North-western Queensland, Australia, contains over 200 fossil bearing localities from the Oligo-Miocene. The study presented here aims at finding new methods to improve the accuracy of palaeoecological and biochronological studies and describe the palaeoenvironmental and chronological settings of the Riversleigh fossil deposits. One of the methods developed in this thesis, Minimum Sample Richness (MSR), determines the minimum number of species that must be present in a fauna to allow meaningful comparisons using multivariate analyses. Using MSR, several Riversleigh localities were selected for a palaeoecological study using the cenogram method to determine the palaeoenvironment during the Oligo-Miocene. Finally, the Numerical ages method was used to refine the relative ages of the Riversleigh localities and a re-diagnosis of the Riversleigh Systems is proposed

Full textWe are going to explain how the aristocrats, more particularly those belonging to the middle and the low aristocracy adjusted to maintain their domination over the peasantry while the power of the count was still active (the viscount being his representative and gaining no independence) and the church was claiming more and more power. The church, in particular, played an essential part in the “de-parenting” of social relationships. The small calibre of most of these aristocrats enabled the count and the church to take over, particularly after 1130, the creation of many “castelnaux” and new towns. In front of those two powers, the aristocrats implemented strategies to assert their authority, to impose themselves locally by allowing an increasing number of serfs to settle in hamlets or inventing new taxes (after they lost the tithe for instance) ; they also circumvented difficulties : marital interdictions were not respected in order to prevent the fragmentation of patrimonies in a region where an egalitarian sharing existed. A political history of Bas-Quercy and Haut-Toulousain is set by way of an introduction. The next five chapters will represent the core of this research and will resolutely deal with the description of behaviours : naming, allying (marriages and relationships as well as fiefs and peers), demonstrating faith and dominating. The role and function of women will be mentioned in each chapter. As an appendix, there will be a file about twenty or so aristocratic lineages among the most representative ones of the diversity of situations

Full textTravertines are karstic carbonated deposits, and are well recording the evolution of passed climates and natural environnement. First, these deposits are related with the period of improved climate, more precisely, in the last interglacial period. In this period, big deposits of travertines appeared. They contained several kinds of informations concerned passed environnements, which are dating. Since the holocene period, the human interference became more and more important. Fine calcimetry can precise the composition of carbonates sediments and the biological processes. The travertines are influenced by the human interference since 7000 years. Nowdays, this human pressure is very strong and break the natural process of deposition, which resulted of karstic and biological influences. The endokarst and its hydrochemistry can explain the actual dynamic of deposition, in relation with hydrodynamic of spring and river. The dilution of karstic water can explain the absence of big deposits of travertines. In fine, this deposit resulted of the karstic dynamic and the human interference. They appeared like "karsto-anthropic" forms. These deposits are very recent, under 200000 years, in the perigord-quercy area

Full textThis thesis consists in studying a definite geographical area (1550 km2) in the departments of Lot and Tarn-et-Garonne. The research has been carried out into several subjects. The first one was the problem of the definition of a parish, especially before the term "parrochia" appears in the texts. A definition of the parish as a territorial entity seems to be the best. Indeed, the notion of territory attached to the church doesn't appear before the 10th or the 11th century. We notice a high density of churches in the South of the Quercy as early as the end of the 7th century. They were nearly all villa's annexes. This sketch has persisted until the 950's. After that there appears to be a revolution followed by the apparition of new types of settlements. The first one is the scattered settlement, "mas", "cammas", "casals" which seems to have been the basis of the social organization and of the assessment of the taxes. If the generalization of the "mas" seems to have taken place early, the settlement of population grouped in villages has been late and partial. We have defined two phases. From 1050 to 1130-1140 the villages are composed of very few houses. The church, except near the bishop's town, is not the principal reason for grouping. On the contrary the castle, with various situations, acted as center of attraction for settling down. After 1130-1140, the trade becomes the mainspring of village's foundations, like Montauban, Montech, Castelsarrasin in the 12th century, or the "bastides" and "castra embastidés" like Realville, Castelnau-Montratier or Montpezat between 1230 and 1320. The last chapter deals with the formation of the territorializated parochial system. It begins to appear in the 10th century, with the "arum" which is a vicaria's subdivision. In the 13th century the system is generalized. This process, although it takes place at the same time, seems to be separate from the village's genesis

Full textThis thesis is about contribution of young inhabitants ( between 15 and 25 years old) in cultural dynamism and futur of rural areas, through artistic and cultural behaviours, initiatives and events. This research takes into account the strong appeal of rural territories wich is shown by population’s movements and new social composition. The thesis deals with a context where cultural politics are built on a local level, are related with local development and are based on empowerment of the population. This work leans on a qualitative methodology semi-directive, interwiews, free discussions and on participating observations. The first goal is to understand how young inhabitants make their local life environment active by their artistic and cultural behaviours. The next goal is to research the link between their way of living and their background, and try to understand the need of regular back and forth trips between town and country, between here and elsewere. This approach allows us to grasp the capacity they have to build the collective places in wich they’re living, and gives a way of understanding collective dynamics of coming years

Full textTowns and small towns of the High Quercy are a good subject for a general study about urban defences during the Hundred Year’s War : their archives and the studies concerning them are rather numerous to be effectively used in connection with the most recent works of urban history and military history. Facing a mobile and rather well organized enemy, consulates defined important programs of fortification, but they had to take into account strong political and financial constraints to implement them ; the protection of the back-countries was even more difficult to realize. Within this framework, the choices made by the municipalities mainly explain the way in which the royal capacity considered the defence of the province, and finally happened to expel the enemy troops of it. The setting in defence had for first consequence an unprecedented reinforcement of the legal and tax powers of consulates, but it is through the management of the watch that the consular world took powerful ascending on the population. The guard was also at the origin of important economic losses, but, for these societies which had largely integrated the war, it was there only one of the multiple consequences of defence. The municipalities tried despite everything to fight against the perverse effects of the calamities, but they could not prevent important social changes from occurring. During the conflict, the consular elites used their political positions to maintain their situations privileged compared to the remainder of the population ; on the strategic level, the economic and military roles of the strengthened city were specified

Full textThe characterization of stigmas volatiles has allowed gaining further insight into the aroma of saffron. The specificity of saffron from the Quercy area has been demonstrated. The main volatile compound of fresh stigmas is linalool. High moisture content induces an increase of HTCC and safranal (spicy note), a loss of colour and the formation of 3-methylbutanoic acid (animal note). The molecular potential of bulbs, leaves and flowers has been evaluated to suggest novel utilisation strategies for the by-products of saffron cultivation. Bulbs contain a high amount of starch and their lipid fraction is rich in omega 6 fatty acids. Concretes from flowers and leaves give "honey" (2-phenylethanol) and "green" notes. Carotenoïds from flowers and leaves were identified as C40H56O4 and C40H56O2 xanthophylls, esterified by fatty acids in the case of flowers. The extraction of aromatic and colouring molecules has been successfully tested at pilot scale

Full textThe material from 90 localities, paleokarstic in most part, has been gathered together in order to study the Western Europe bat evolution and diversity from the middle Eocene (~44 Myr) up to the early late Oligocene (~29 Myr). The morphological and biometrical observations and comparisons of the tooth material allow recognizing 7 families, 10 genera and 52 species. Several taxa of various systematic rank were described as new ones: 1 family, 2 genera, 1 sub-genus and 21 species. Thanks to these first results and the long involved time extent (more than 10 myr), this work suggested some phyletic hypothesis. Among others were discussed the relationships between the new mixopterygid fossil family and the emballonurid and hipposiderid fossil and extant families, and by the way considering their molecular data. The peculiar Necromantis fossil genus being now better documented, its particular inferior molar pattern was exemplified as defining the necromantodont pattern. Even if the Necromantis affinities still remain unclear, the new data allowed to show the previous megadermatid assessment as being irrelevant. Thanks to the available information from the bat material, the relative datation of yet unstudied and undated new localities were proposed from biochronal reference-stages, characterized by some bat species with a given size and morphology. Also, further data were supplied for faunas dated by the numerical ages method. The taxonomic biodiversity of the studied faunas was also evaluated using other fossil material (humerus, wing-shape, tooth wear…) and when possible it was illustrated from the studied material. This approach showed us the constant need to consult the present faunas in order to better understand the fossil ones. So, two quantitative analyses are realized, bringing out informations about the structure of the fauna. First, a Principal Component Analysis of the tooth-shape showed that the premolars (P4/4) and molars Length/width ratio is characteristic for each genus. Second, the comparison of fossil and present bat cenograms suggested that the body weight composition of the community is linked to the nature of the environment in which it evolves. Finally, these analyses allowed us to deduce some bat evolutive modalities either by the variations of weight interval, either by the proportion of the different weight categories. They showed that extinctions preferentially affect morphologically or weightly extreme species. Consequently, this allowed discussing the effect of Stehlin’s faunal “Grande Coupure” event among the Western European bats at the Eocene-Oligocene boundary

Full textThe study is about a whole of wall paintings found in situ that precise time criterions, from dated or named inscriptions, from records or from armorials bearings, that relative time criterions, about iconographic data, put between the end of the xv century and the beginning of the xvii century. From previously written accounts on more than ninety visited sites, accounts related to pictures and drawings, the main subject of the study is to show the typical outlines of a renaissance wall painting in the studied area. Particularly the adaptation of the picture to an architecture, the composition of the stage, the representing of the figures and the anatomic knowings, the use of a more or less scientific perspective, which takes care of the spectator, and the translation of the relief by the modele technic, which suggests the third dimension to the trompe l'oeil. The aim of the study is also to show the importance took by the setting in the wall painting at this time, to even hide the stage and create, because of permanent or found designs, a new iconography, which has its own symbolic

Full textL'évolution naturelle des mares conduit à leur atterrissement et une étude comparative de trois mares à différents stades de comblement a montré l'évolution des paramètres abiotiques (température, concentration en oxygène dissous...) en fonction du niveau de comblement. Parallèlement, les mares varient en terme de richesse spécifique de la faune et de la flore. Chaque stade de comblement abrite une faune particulière et participe à la biodiversité globale de ces milieux et même de l'écosystème caussenard dans son ensemble.
Pour analyser ces milieux à une échelle supérieure, des échantillons ont été récoltés sur trente mares afin d'étudier les facteurs affectant la distribution de la faune dans un réseau de mares. Nous avons identifié 230 espèces d'invertébrés et 6 espèces de vertébrés. Les résultats ainsi obtenus ne permettent pas de dresser une typologie des mares ni de dégager des peuplements caractéristiques ou de réaliser une classification ascendante de ces milieux. Les mares entourées d'une matrice terrestre sont assimilables à des îles pour la faune aquatique.
C'est pourquoi nous avons choisi d'étudier plus précisément la distribution de cinq groupes ayant des capacités de dispersion différentes : Odonates, Coléoptères, Amphibiens, Mollusques et Oligochètes. La surface des mares affecte la distribution des Odonates. Le pourcentage de forêt autour des mares influence la distribution des
Amphibiens. Pour les Mollusques et les Oligochètes, les animaux à dispersion passive, les résultats indiquent que la distribution des espèces est similaire à une distribution au hasard. Pour les Coléoptères, la distribution des espèces n'est pas due au hasard mais nous n'avons pas pu mettre en évidence les facteurs explicatifs de cette distribution.
Nous avons utilisé la méthode de capture-marquage-recapture pour estimer le degré de lien de trois populations en patch d'Odonates. Nous avons montré que trois facteurs influencent la dispersion des Odonates : des facteurs abiotiques (conditions météorologiques), des différences inter spécifique (sensibilité aux conditions météorologiques, taille et comportement des espèces), des différences intra spécifiques (âge et sexe).
Ces travaux mettent en évidence le rôle des mares au niveau de la biodiversité, le rôle du réseau de mares et de l'évolution temporelle des paramètres dans le maintien de cette biodiversité. Les différents résultats obtenus sont discutés en vue de proposer une méthode de gestion rationnelle et durable de ces milieux.

Full textIn the second half of the 20th century, hunting has changed. From a free random sampling of game, it has been orientated towards concepts of mildly intrusive wildlife harvest and management. Characterizing French hunting, in particular when practiced traditionally, with hounds, is that the dueling-play with the wild game has persisted, though with some difficulty. Having been scarce for a long period, wild boar, just as other lowland ungulates, experienced a strong demographic increase over the last three decades. The species nowadays causes harm to human activities which can be rather serious. And while only the hunters regulate wild boar population, contributing at the same time to the financing of the Hunting Administration and of the compensation of agricultural damages, their own numbers are in a clear and ongoing decline. Public authorities are confronted with the necessity to control wild boar populations. In order to optimize the efficacy of hunting activities, the rules submitted and imposed to the hunter are progressively put into question to the benefit of the return of techniques which had been barred much earlier. Moved by an extraordinary passion, hunters, through the practice of their leisure activity, make a contribution to the public interest. However, they do not eagerly accept the objectives which are set for them, nor the second conceptual revolution which is imposed on them. Representations, symbolism, the relationship with game, wildlife and nature are equally underlying in the hunters’ culture and way of thinking, and at the same time they do guide his actions and choices. With the risk to jeopardize the chances of success of the new public policies, it appears that these founding and essential dimensions of the hunting act need to be taken into consideration when promoting measures such as in the normative actions undertaken by the three-party Administration “sui generis” characterizing hunting in France, involving the State, a specific public establishment and the hunters’ federations

Full textThis doctoral research is a comparative study of the late bronze age ceramics from two areas located in West and North of the Massif Central: the Quercy and the Basse Auvergne. The materials analyzed are all dated of the middle phase of the late bronze age and come from various contexts (high ground settlements, lowland pits, and burial caves). At first, we develop a typo-chronological classification method based on quantitative and statistical processing of morphological and decorative attributes of the ceramics that allows distinguishing two regional stylistic variants. Their chronological boundaries indicate that some shape and decorative changes occurred with a slight time lag. Secondly, we question the utilization of these different types. We identified several classes based on use wear and technological features. These vessel classes all together with their metallic equivalent when available were analyzed in regards to site function. In burial cave contexts, food and liquid consumption vessels prevailed; numerous connections with metallic items indicate a distinction with habitation contexts and attest of ceremonial banquet. Ceramic assemblages from high ground contexts can be distinguished from the lowland ones by a larger proportion of collective table vessel. We finally conduct an analysis of ceramic manufacturing following a "chaîne opératoire" approach. We identified same chronological changes in the two research areas based on paste preparation, shaping and finishing techniques, and heating procedures. On the contrary, several technical choices indicate a regional patterning and the existence of local specificities. Nevertheless, a fine vessel equivalent to the metallic one, involved greater skills and possibly denotes the emergence of craft specialization. Based on these results, we stress the need for a multi-scale approach in the interpretation of the extension and spread of typological and technological traits because their accuracy and integration level can vary

Full textThe retro-arc foreland basin of the Central Andes is considered as a type-example of a foreland basin system (Horton & DeCelles, 1997). Three regions have been studied : the North Amazonian basin (3-8ʿS), the South Amazonian basin (11-12ʿS) and the south-eastern Bolivian basin (19-20ʿS). The foreland basin system of the Central Andes constitutes a favoured area where studies of the deformation and sedimentary fill can be coupled. This study enabled us to arrive at a clearer understanding of the longitudinal and latitudinal structural/sedimentary evolutions and of the tectono-sedimentary dynamics of the basin and adjacent orogen, and to a sequential restoration of the basins at key-periods in the evolution of the range from the Eocene to present-day. During the early and middle Eocene, the Western Cordillera of northern Peru between 3 and 8ʿS experienced large uplift and erosion. This event is interpreted as a stage of tectonic quiescence and erosional unloading. To the south of 11ʿS, no such event is recorded in the sedimentary fill and the sedimentary arrangement indicates the development of a flexural basin related to orogenic loading. Because the North Amazonian foreland basin system is situated at the junction between the Central Andes and the Northern Andes, this change in the geodynamic process can be ascribed to the interference with the Northern Andes. .
