História das caretas: a tradição Borda Incisa na Amazônia Central / History of the grimaces: the Incised Rim tradition in the Central Amazon

Helena Pinto Lima 28 August 2008 (has links)
Esta pesquisa expõe contraposições teóricas e empíricas aos clássicos modelos de ocupação da Amazônia. Através de uma fusão entre base empírica e o corpus de conhecimento atualmente disponível, propõe uma história de ocupação da Amazônia central agenciada por grupos culturais integrados através de um complexo sistema sócio-político, que extrapolou fronteiras étnicas, lingüísticas e ambientais. Este sistema estaria materializado na tradição Borda Incisa e teria se desenrolado ao longo de muitos séculos, com início em torno do anno domini e se estendendo até os séculos XI e XII d.C. A esta intrincada rede macro-regional, que aqui denomino Esfera de Interações, estão ligados elementos como a padronização de um sistema de comunicação, expresso através da cultura material e das formas de usar e organizar o espaço. A cronologia apresentada neste doutoramento também oferece parâmetros para uma reavaliação do uso de conceitos arqueológicos tradicionais, como as fases e tradições. Logra-se maior flexibilização de tais categorias, uma vez que a fluidez de limites é inerente aos conjuntos artefatuais estudados. Na área de confluência dos rios Negro e Solimões, esta história é contada através do entendimento das relações entre as fases Açutuba, Manacapuru e Paredão. / This dissertation offers new theoretical insights and empirical data that supplements some of the classic models of occupation of Amazonia. Through a combination between empirical data and current knowledge, the dissertation proposes a history of occupation of the Central Amazon region that places cultural groups integrated in a complex socio-political system extending beyond ethnic, linguistic and environmental boundaries as its main agents. The material correlates of this system, which developed from around the beginning of the Christian era and reached until the eleventh or twelve century AD, would be pottery and associated contexts of the Incised Rim tradition. This intricate macroregional network, in effect an Interaction Sphere, includes such features as a standardisation of communication systems expressed in material culture and in forms of using and organizing space. The chronology presented in this dissertation also provides pointers to reassess the use of traditional archaeological concepts such as phases and traditions. It employs these categories with some flexibility inasmuch as the sets of artefacts that have been studied show inherent fluidity in their definitions. In the confluence area of the Negro and Solimões rivers, this permits unravelling a history that is based on an understanding of the relationships between the Açutuba, Manacapuru and Paredão phases.

Ocupações humanas pré-históricas no litoral maranhense: um estudo arqueológico sobre o sambaqui do Bacanga na ilha de São Luís - Maranhão / Pre-historic ocupations humans at Maranhense coast: an study of Bacanga Shell Midden at São Luís Island-Maranhão

Arkley Marques Bandeira 30 May 2008 (has links)
A presente dissertação discorre sobre a ocupação pré-histórica da Ilha de São Luís-Maranhão, a partir do estudo arqueológico realizado no sambaqui do Bacanga, que evidenciou vestígios materiais de populações pescadoras- coletoras- caçadoras e ceramistas, que se estabeleceram na região, em torno de 6.600 anos antes do presente e permaneceram habitando esse assentamento até o ano 900 antes do presente. A pesquisa em questão, pautada nos pressupostos teórico-metodológicos da Arqueologia da Paisagem e da Antropologia das Técnicas, aglutinou uma gama de especialidades, que se envolveram na datação de material arqueológico, na análise técnica da cerâmica, na identificação dos vestígios arqueofaunísticos, no levantamento topográfico, altimétrico e na execução de plantas e desenhos da distribuição espacial dos vestígios, bem como na caracterização geoambiental, além da própria análise dos dados arqueológicos, principalmente o material cerâmico. A descrição, interpretação e a correlação das informações obtidas no sambaqui do Bacanga permitiram construir conhecimento inédito sobre os processos ocorridos na préhistória da Ilha de São Luís, ao atestar a existência e permanência, por um longo período de tempo, de populações pescadoras- coletoras- caçadoras e ceramistas adaptadas a ambiente estuarino-marinho, cuja dieta envolvia a captura de uma variedade de animais e a coleta de algumas espécies vegetais, mas que contudo, encontrava a sua base de sustentação na pesca e na utilização de crustáceos e moluscos como alimentos. O foco da análise centrou-se na investigação do modo de vida de tais populações, a partir da caracterização técnica e tipológica da cerâmica, uma vez que a presença desse tipo de evidência em sambaquis tem sua área geográfica bastante circunscrita no Brasil, envolvendo majoritariamente algumas regiões do Pará, Maranhão e em menor escala Sergipe e Bahia. Além disso, um aspecto de fundamental importância para arqueologia brasileira e que não se obteve paralelo na literatura analisada relacionou-se à descoberta de um assentamento ceramista pré-sambaqui, cuja localização era a mesma do sambaqui do Bacanga, estando situado nas camadas mais antigas de ocupação, algo entre 6.600 a 5.500 anos antes do presente, com grande concentração de cerâmica, sem, no entanto, apresentar o acúmulo de restos alimentares nos pisos de ocupação. Ao passo que as populações pescadoras- coletoras- caçadoras e ceramistas do sambaqui propriamente dito, assentaram-se entre 5.000 a 900 anos antes do presente. Em síntese, a inserção do sítio em questão, nas escalas espaciais, temporais e ambientais, bem como o estudo dos vestígios arqueológicos estabeleceram parâmetros pioneiros para que futuras pesquisas no Maranhão encontrem referenciais de suporte e levem em consideração a história de longa duração dos primeiros povoadores da Ilha de São Luís. / The present dissertation discusses about the pre-historic occupation at São Luís Island-Maranhão, from the archaeological study realized at Bacanga Shell Mound, that appointed material vestiges of the fishing-collecting-hunters and ceramists populations that settled in the region, around 6.600 years before present and remained living this settlement until 900 before present. The research, based in theorical-methodological issues of the Landscape Archaeology and the Technicist Anthropology, united a variety of specialties, that were involved in the archaeological material process of date, in the analyses of ceramics, in the identification of archaeofaunistical vestiges, in the topographical, altimetrical research and in the execution of plants and drawings of this site, in the geoenvironmental characterization, besides the analyses of the archaeological information, mainly the ceramics remains. The description, interpretation and co-relation of the information obtained at Bacanga Shell Mound allowed to build inedited knowledge about the processes occurred in the pre-history of São Luís Island, testifying the existence and permanence, for a long period, of fishing-collecting-hunters and ceramists population adapted to estuary-sea environmental, whose diet involved the gathering of a variety of animals and gathering of some vegetable species, but, the, however, found support in the fishing and in the crustacean and mollusks as food. The focus of analyses was centered in the investigation of the way of life of this population, from the technicist and typological characterization of ceramics, considering that the presence of this kind of evidence in shell mounds has its geographical area really circumscribed in Brazil, involving majorly some regions in Pará, Maranhão, and, in a minor scale, Sergipe and Bahia. Besides that, as aspect of fundamental importance to the brazilian archaeology and that does not have parallel in the literature analyzed related to the discovery of a pre-shell mound ceramist settlement, whose, localization was the same of Bacanga shell mound, being localized in the older layers of the settlement, from 6.600 to 5.5000 years before present, with big concentration of ceramics, without, however, presenting an accumulation of food residues in the settlement floors. Making a summary, the insertion of this site, in spatial, temporal, and environmental scales, and the study of archaeological vestiges establish primary parameters to future researches in Maranhão, finding references of support and considering the long duration history of the first population in São Luís Island.

Monnaie et société chez les peuples gaulois de la basse vallée de la Seine : recherches sur les usages monétaires d’une région entre le début du IIIe et la fin du Ier siècle av. J.-C. / Coin and Society among Gallic’s people in the low valley of Seine : researches about the monetary uses of a region from the beginning of the IIIrd century to the end of the Ist century BC.

Guihard, Pierre-Marie 21 November 2009 (has links)
Traditionnellement, la monnaie gauloise est abordée comme un objet d’étude autonome, détaché de son environnement. L’usage qu’en avaient les Celtes de la Gaule préromaine n’a pas suscité de nombreux écrits, peut-être éclipsé par un art monétaire d’une exceptionnelle qualité. Pourtant, la monnaie, au même titre que tout autre objet issu de la Pensée, trouve sa justification par une fonction, matérielle et concrète pour les hommes amenés à la manipuler. La démarche qui est menée ici tente donc de combler cette lacune, à travers un exemple précis et représentatif : L’histoire monétaire des peuples gaulois de la basse vallée de la Seine entre le début du IIIe siècle et la fin du Ier siècle av. J.-C. Elle replace désormais la monnaie dans la société qui l’a engendrée. Pour partir à la recherche des usages monétaires, il a été nécessaire de s’intéresser aux choix faits par les autorités émettrices en matière de types et de dénominations (poids et étalons), mais aussi de s’interroger sur le sens des légendes monétaires et les dynamiques de circulation, c’est-à-dire la durée et la destination des monnaies sur la région. La documentation prend en compte près de 4000 monnaies en or, argent, potin et bronze, toutes issues de milieux variés (trésors, gisements archéologiques et découvertes isolées). Pour gagner en substance, cette collecte préalable a été confrontée à deux autres sources de documentation. L’une est littéraire. Elle a permis, d’après les témoignages des auteurs grecs et latins, de replacer le fait monétaire dans son environnement socio-historique. L’autre est archéologique. Elle a favorisé, grâce à sa démarche objective, une meilleure perception du rapport des populations locales à la monnaie. De là, il a été possible de reconstituer depuis son origine, au début du IIIe siècle av. J.-C., l’histoire des pratiques monétaires sur la basse vallée de la Seine, tout en apportant des renseignements sur les contextes socio-économiques dans lesquels la monnaie a été employée. Cette thèse met ainsi l’accent sur l’aptitude des sociétés gauloises à bâtir leur propre système monétaire, bien loin du cliché d’un Astérix utilisant des sesterces pour ses achats. / Traditionally, the Gallic’s coin is tackled as the subject of an autonomous study, untied off its environment. Its use by the Celtic of pre roman Gaul has not generated lots of writings, maybe outshined by a monetary art of an exceptional quality. Though, the coin, as every object from the Thought, finds its justification by a function, practical and concrete for the mankind lead to handle it. This thought process attempts therefore to fill this gap, through precise and representative example: the monetary history of the Gallic’s people in the low valley of Seine between the beginning of the III century and the end of the first century B.C. It replaces from now on the coin in the society which fathers it. To be able to research the monetary uses it has been necessary to be interested in the choices done by the issuing authorities for the models and designations (weights and standards), but also, to wonder about the meaning of the monetary legends and of the dynamic movements, that is the duration and the destination of the coins in this region. The documentations takes into account close to 4000 coins in gold, silver, potin and bronze, all coming from various environments (treasures, archaeological deposits and isolated discoveries). To have more essence, this previous collection has been compared with two other sources of documentation. One is literary. It has allowed, according to the testimonies of the Greek and Latin authors, to replace the monetary fact in its socio-historical environment. The other one is archaeological. It has facilitated, thanks to its objective thought process, a better perception of the relation of the local populations with the coin. From there, it has been possible to piece together from its origin, at the beginning of the III century B.C., the history of the monetary uses in the low valley of Seine, in the same time providing informations about the socio-economics context in which the coins was used. This thesis puts a slant on the aptitude of the Gallic’s societies to build their own monetary systems, far from the cliché of an Astérix using sestertium for his purchases.

Linking lake variability, climate, and human activity in Basotu, Tanzania

Higgins, Lindsey January 2017 (has links)
Paleoenvironmental investigations establish important baseline knowledge of the natural variability of lake systems, to better understand human impacts on the landscape, and the effects of climate change on water resources. By combining long-term environmental history with investigations into modern land use patterns and climatological events, a wider perspective can be reached that has practical applications in water governance. This thesis presents a case study of Lake Basotu (4.37°S, 35.07°E), a crater lake in the Hanang district of north-central Tanzania, which acts as an important source of freshwater for local people. A three-meter long sediment core from an interior crater of Lake Basotu was investigated using proxy records (diatoms, magnetic parameters, and carbon content) and radiometric dating (14C and 210Pb). The Lake Basotu record was then compared to other sediment-based reconstructions from East Africa and records of historical famines to better place it into the timeline and understanding of regional climate dynamics. This work was extended into modern times (1973–2015) by examining lake extent variations in the Landsat satellite archive. Shoreline boundaries for dry-season images were delineated and lake extent was calculated using GIS techniques. This remote sensing record was compared to climatological patterns, meteorological records, and the history of land-use changes in the surrounding district. As a whole, the Lake Basotu record indicates that major fluctuations in lake level are not abnormal; however, human influence has likely increased the lake’s sensitivity to climatic fluctuations. The timing of historical famines in East Africa were linked to periods of shallow lake conditions in Basotu, and the duration of the most extreme lake level changes correlate to a reversal in the 14C age-depth model. Recent variations in lake extent are likely connected to a mechanized wheat farming program implemented in the district as a foreign aid project in the early 1960s. To support the work done in Basotu, a preliminary investigation of sediment from the nearby Lake Babati was undertaken. Sediment from the two lakes indicates that their geographical location may be in a transition zone towards dryer conditions to the south during the Little Ice Age in East Africa. The results of this thesis support that Lake Basotu is an important location for understanding the potential impacts of climate change and human activity on water resources in this region. / <p>At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 1: Manuscript.

La représentation du bubale antique dans l'art rupestre de l'Atlas saharien (Algérie). / The representation of the antique buffalo in the rock art of Saharan Atlas (Algeria)

Khaled, Fatma Zohra 30 November 2015 (has links)
Parmi les représentations animales gravées qui apparaissent en Afrique du Nord au cours de la Préhistoire, le bubale antique, omniprésent dans tout l'Atlas saharien tout au long du Néolithique, occupe une place prépondérante.Notre étude a porté sur 141 gravures du bubale antique, réparties dans les différents chaînons composant l’Atlas saharien dont 79 ont été étudiées par nous-même sur le terrain. Cette étude a permis de regrouper et d’analyser les données dispersées dans de multiples travaux, auxquelles se sont ajoutées nos découvertes qui ont enrichi l'inventaire et ont élargi la répartition spatiale de ces gravures. Cette richesse n'est pas seulement quantitative, elle est aussi qualitative. Il en ressort d'importantes variations stylistiques, thématiques et techniques permettant de mettre en lumière les écoles régionales et les influences sahariennes. Nos recherches ont permis une meilleure compréhension des traditions stylistiques et iconographiques de la figuration de cet animal et nous ont permis de mieux les situer dans leur contexte chronoculturel et géographique.Les représentations du bubale antique dont certaines formes élaborées participent à la définition de provinces culturelles, révèlent l'investissement et le choix des artistes au sein d'un bestiaire varié qui a été différemment représenté selon les régions et les écoles atlasiques. / Among the carved animal figures that appeared in North Africa during prehistory, the antique buffalo, omnipresent throughout the Saharan Atlas during the Neolithic, features prominently.Our study focused on 141 of these hartebeest engravings, spread over the various links constituting the Saharan Atlas of which 79 have been studied by us on the spot. This study consolidates and analyses data scattered in multiple works, to which are added our discoveries which have enriched the record and expanded the spatial distribution of these engravings. This wealth is not only quantitative, it is also qualitative. This important spring stylistic, thematic and technical highlights the regional schools and Saharan influences. Our research has allowed a better understanding of the stylistic and iconographic traditions of figuration of this animal and allowed us to situate them in their chrono-cultural and geographical context.The representations of the antique buffalo whose developed some forms, involved in defining cultural provinces, reveal the investment and the choice of artists in a varied bestiary that was represented differently depending on the region and atlasiques schools.

Reconstitution du flux d'impact et des variations paléoclimatiques martiennes par la datation des cratères à éjecta lobés / Reconstitution of the impact rate and martian paleoclimatic variations by layered ejecta craters dating

Lagain, Anthony 17 November 2017 (has links)
Le comptage de cratères sur une surface planétaire est à l’heure actuelle le seul moyen de préciser la temporalité des événements ayant marqué l’histoire des corps telluriques. Cette technique nécessite de connaitre précisément le taux avec lequel se forme les cratères d’impact, c'est-à-dire le flux d’impact, mais aussi son évolution en fonction du diamètre des cratères, la fonction de production. Ensemble, ces deux variables forment le système de chronologie d’un corps planétaire. Il est relativement bien contraint entre 3,9 et 3,5 milliards d’années avant notre ère et considéré comme constant depuis 3 milliards d’années, une hypothèse remise en cause par des observations lunaires et terrestres. Les cratères d’impact à éjecta lobés sont très nombreux sur Mars. Leur morphologie traduit la présence d’une grande quantité de glace d’eau dans le sous-sol au moment de l’impact. La variation spatio-temporelle de cette couche est très peu contrainte. Celle-ci est principalement influencée par l’obliquité de la planète. Leurs nappes d’éjecta sont continues et constituent donc des surfaces idéales pour dater leur formation. L’objectif de cette thèse est de mieux contraindre la chronologie martienne et la variation de l’extension de la couche de volatiles présente sous la surface de Mars responsable de telles morphologies. Par la datation de la mise en place d’une population de cratères à éjecta lobés situés sur Acidalia Planitia, il a été possible de comparer leur fréquence de formation avec le flux d’impact qui a été utilisé pour les dater. Un important désaccord entre nos données et le modèle à flux constant a pu être observé. Un test d’autocohérence entre le flux d’impact mesuré et le flux utilisé pour dater chaque cratère a permis de montrer que le taux d’impact le plus en accord avec nos données était celui présentant un pic de cratérisation entre 0,5 milliards d’années et la période actuelle. Ce pic est associé à deux collisions dans la ceinture principale d’astéroïdes. Néanmoins, cette méthode inverse est soumise à un problème logique mis en évidence par la simulation d’une population de cratères synthétiques. Il apparaît à posteriori que la variable temporelle de la chronologie martienne doit être la fonction de production des cratères d’une centaine de mètres de diamètre. Ces résultats modifient profondément l’âge des surfaces martiennes qui peuvent être mesurés par comptage de cratères. La datation de l’ensemble des cratères martiens dont les nappes d’éjecta lobés sont très étendues a permis également de mettre en évidence une augmentation de l’âge de ces cratères avec la diminution en latitude. Nous avons interprété ces observations comme étant le résultat de l’évolution récente de l’extension de la couche riche en volatils sous la surface de Mars, en lien avec la variation de l’obliquité de la planète. En effet, une diminution de l’angle d’obliquité de Mars il y a 4 millions d’années a restreint l’extension de la couche de volatils à haute latitude. Le lien étroit entre la localisation de ces cratères et leurs âges a permis de poser certaines conditions quant à l’évolution possible de l’obliquité martienne sur les 80 derniers millions d’années. Enfin, la révision de la base de données de cratères martiens la plus complète à ce jour au moyen d’une interface accessible à tous a permis de créer le premier catalogue de cratères adapté à la datation de surfaces martiennes. Nous avons pour cela mis en place une classification des cratères permettant l’exclusion, lors d’une datation, des cratères de type secondaire, fantôme ainsi que des fausses détections contenus dans la base de donnée originelle. / Counting craters on planetary surfaces is currently the only way to precise the events temporality which have marked the history of terrestrial bodies. This technique requires the precise knowledge of the rate with which impact craters are emplaced over time, the impact flux, but also its evolution in function of crater diameter, the production function. Together, these two variables constitute the chronology system of a planetary body. This system is relatively well constrained between 3,9 and 3,5 billion years before present and considered to be constant since 3 billion years, a hypothesis challenged by earthly and lunar observations. Layered ejecta craters are numerous on Mars. Their morphology is related to the presence of ice-rich material in the subsurface at the moment of the impact. The spatial and temporal evolution of this layer is poorly constrained. This one is primarily influenced by the obliquity of Mars. Their ejecta blankets are continuous and therefore constitute ideal surfaces to date the impact itself. The purpose of this thesis is to better constraint the Martian chronology and to better understand the variation of volatiles layer extent present under the surface of Mars. By the dating of the formation of a layered ejecta crater population located on Acidalia Planitia, it has been possible to compare the emplacement frequency of these structures with the impact flux that has been used to date them. An important mismatch between our data and the constant flux has been noted. An auto-consistency test between the measured impact rate and the rate used to date each crater has shown that the most consistent flux with our data is a cratering spike between 0,5 billion years and the actual period. This spike is associated to two main asteroid break-ups in the main asteroid belt. Nevertheless, this inverse method is challenged by a logical problem highlighted by the simulation of a synthetic population of craters. It appears a posteriori that the temporal fluctuation of the Martian chronology comes from the production function of impact craters of hundred meters of diameter. These results modify considerably the age of the Martian surface that we can measure by counting craters. The dating of all craters which exhibits a high extent of their ejecta blankets has also allowed to highlight an increasing of their age with the decreasing of the latitude. We have interpreted this observation by the result of the late evolution of the volatiles layer extent under the surface of Mars, linked to the shift of the obliquity. A decreasing of the Martian obliquity angle there was 4 million years ago has restricted the volatiles layer extent to high latitude. The close link between the location of these craters and their ages has allowed us to set some conditions of possible evolution of the Martian obliquity during the last 80 Myrs. Finally, the correction of the most complete Martian crater database thanks to a web interface accessible to everyone has allowed to create the first crater catalogue adapted to the martian surface dating. We have developed a crater classification allowing the exclusion, during a surface dating, of secondary craters, ghosts craters as well as false detections contained in the original database.
