A presente pesquisa trata de aspectos funcionais e espaciais de um conjunto de sítios arqueológicos localizados na área setentrional do Pantanal Mato-grossense conhecida como Pantanal de Cáceres. Inseridos no contexto de diversidade cultural que caracteriza a região do Gran Chaco e Alto Paraguai, sítios arqueológicos associados à cerâmica Pantanal - atribuída a grupos pescadores-caçadores-coletores, e à cerâmica Descalvados - atribuída a grupos cultivadores - são discutidos a partir de seu material lítico e cerâmico, bem como da distribuição espacial desses vestígios. Pela primeira vez é realizado um estudo sobre o material lítico da ocupação Descalvados, evidenciando uma indústria de adornos. Ao longo do trabalho diferentes níveis de relações são explorados, desde as possíveis funções dos sítios no âmbito de sistemas de sítios, como a organização interna de um sítio da ocupação Descalvados. Para a discussão de sistemas de sítios são consideradas variáveis paisagísticas e a variabilidade presente no material arqueológico de distintos sítios. Para a discussão da organização interna de um sítio são comparados materiais cerâmicos e líticos, além de estruturas arqueológicas, aos quais foram atribuídas determinadas funções. Oposições binárias como tralha doméstica versus parafernália ritual, e espaços domésticos versus espaços funerários são exploradas numa perspectiva estruturalista, permitindo vislumbrar aspectos materiais e não materiais da ocupação Descalvados. A discussão extrapola a abordagem funcionalista ecológica, à medida que trata de aspectos que vão além das funções práticas dos elementos materiais e espaciais. São também testadas algumas hipóteses construídas previamente, tais como as funções das vasilhas cerâmicas, e a possível concomitância das ocupações associadas às cerâmicas Pantanal e Descalvados. Novas datações absolutas foram obtidas, preenchendo um lapso temporal que existia para a ocupação Descalvados, e recuando em cerca de um milênio o início da ocupação pelos grupos associados à cerâmica Pantanal / This research deals with functional and spatial aspects of a set of archeological sites located in the northern area of the Mato Grosso Pantanal known as the Pantanal of Cáceres. Within a context of cultural diversity which characterizes the region of the Gran Chaco and Upper Paraguay, archeological sites associated with Pantanal ceramics (attributed to groups of fishermen, hunters and collectors) and Descalvados ceramics (attributed to groups of farmers), are discussed in terms of the lithic and ceramic material, as well as the distribution of these remains. For the first time, a study is being carried out on the lithic material of the occupation by the Descalvados revealing the production of decorations. During the study, different levels of relationships were explored starting from the possible functions of the sites in the realm of site systems through to the internal organization of a site occupied by the Descalvados. In order to discuss the site systems, variables such as the surrounding area and variations in the archeological material present in distinct sites were taken into consideration. For discussion of the internal organization of the site, ceramic and lithic material were compared as well as archeological structures to which specific functions were attributed. Binary opositions such as domestic utensils vesus ritual paraphernalia and domestic space versus funeral spaces are explored from a structuralist perspective permitting a view of the material and non-material aspects of the Descalvados occupation. The discussion extrapolates the ecological, functionalist approach since it deals with aspects which go beyond the practical functions of the material and spatial elements. Also, some previously constructed hypotheses are tested such as the functions of the ceramic containers and the possible concomitance of the occupations associated with the Pantanal and Descalvados ceramics. New absolute datings were obtained filling in temporal gap that existed with respect to the Descalvados occupation taking back the beginning of the occupation by groups associated with Pantanal ceramics by one millennium

Trata-se de um sítio arqueológico com três camadas estratigráficas bem definidas com cinco momentos de ocupação, sobretudo na base, ultima camada pode-se dizer três momentos distintos que o sítio foi ocupado, e pelas datações apresentou períodos de intervalos (abandonos) com uma faixa de até 1000 anos. Geologicamente situado do domínio da Serra do Espinhaço área denominada de Serra Negra (face leste), o sítio está nas proximidades das três principais bacias estaduais, São Francisco, Jequitinhonha e Doce. Para o Planalto Diamantinense há ocupações humanas que constam da transição do Pleistoceno-Holoceno e para o Holoceno-Superior, recentes datações realizadas no sítio Cabeças 04 permitiram identificar uma cronologia que consta para o Holoceno médio, inédita para a região. Com o intuito de se atingir o objetivo proposto, a saber, analisar o conjunto lítico datado do Holoceno médio do sítio Cabeças 04 seguindo o conceito de cadeias operatórias, entendendo sobre as escolhas da matéria-prima, técnicas de redução e inferindo sobre o seu uso social a pesquisa avaliou as possíveis relações tecnológicas e culturais entre o conjunto lítico em pauta com os conjuntos líticos regionais antigos e recentes, portanto, cooperando para informações arqueológicas importantes e inéditas regionalmente, propiciando a ampliação do conhecimento das relações dos grupos e seus ambientes, sobretudo pelas ocupações contínuas na área arqueológica da Serra Negra, a partir de aproximadamente 7000 AP. / The Cabeças 04 site is located in the city of Felício dos Santos, in the Araçuaí river basin, an affluent of Jequitinhonha River, in Minas Gerais. It is an archaeological site with three well defined stratigraphic layers with five moments of occupation. Primarily at the base of the last layer there are three distinct moments that can be noticed that the site was occupied. By the dates it is presented periods of intervals (abandonments) with a range of up 1000 years. It is geologically located in the Serra do Espinhaço area, called Serra Negra area (east side). The site is in the proximity of the three main state basins: São Francisco, Jequitinhonha, and Doce. For the Plateau Diamantinense there are human occupations that consist of the transition from the Pleistocene-Holocene and to the Holocene-Superior. Recent dates made in the Cabeças 04 site allowed to identify a chronology that appears for the Holocene-Middle period, unpublished for the region. The objective was to analyze the lithic complex dated to the Holocene-Middle of the Cabeças 04 site, following the concept of operative chains. It was necessary to understand about raw material choices, reduction techniques and inferring about their social use. In this way, it cooperated to important new archaeological information in the region. It helped favoring the expansion of the knowledge of the relations of the groups and their environments, especially for the continuous occupations in the Serra Negra region, from approximately 7000 AP

Le site Gaudreau est un site perturbé et à occupations multiples situé dans le sud-est du Québec, et présente des occupations datant du Paléoindien Récent jusqu’à la période historique. Les occupations Archaïques du site, noté par la présence de bifaces diagnostiques de l’Archaïque Supérieur et de l’Archaïque Terminal et par des Macrooutils de l’Archaïque Moyen et de l’Archaïque Supérieur, sont le sujet principal de ce mémoire. Puisqu’aucune occupation ne peut être différencié horizontalement ni verticalement, et qu’aucun objet non-diagnostique ne peut être associé avec certitude, seul un échantillon de 32 objets ont été observés. Étant donné la faible taille de l’échantillon analysé, il est fort probable qu’un plus grand nombre de sources de matières premières aient été utilisés durant les occupations de l’Archaïque. Toutefois, un réseau de matières premières lithiques similaire à ceux des sites du Lac Mégantic a été observé, avec une forte représentation de la rhyolite Kineo-Traveller et des cherts Appalachiens. Des cherts des Grands Lacs et le quartzite de Cheshire sont aussi présents. Le mudstone silicifié d’origine locale et le quartz sont par contre faiblement représentés dans l’échantillon, probablement dû à un biais de proximité de source. L’analyse technique de l’échantillon, sans contrôle pour les pratiques techno-économiques, dénote plusieurs récurrences techniques à l’intérieur des unités typologiques, sans toutefois appuyer des différences récurrentes significatives entre les matières premières de régions différentes. À cause de la taille de l’échantillon et du contexte perturbé, la pertinence des fortes similarités entre certains objets est douteuse. La segmentation interpersonnelle des chaînes opératoires ne pouvait être déterminée dans l’échantillon. Cependant, les résultats incitent plutôt à croire que les matières premières devaient circuler sous diverses formes. Il peut être considéré que, en dehors des matières premières locales, les occupants Archaïques du site Gaudreau n’avaient pas d’accès direct aux matières premières exogènes. / The Gaudreau site is a disturbed multicomponent site located in Southeastern Quebec, with occupations dating from the Late Paleoindian into the historic period. The Archaic occupations, noted through the presence of multiple diagnostic bifaces forms and macrotools, are the primary subject of this thesis. As no occupations can be isolated horizontally nor vertically, and no non-diagnostic artifacts can be associated with certitude, only a sample of 32 objects were analyzed. As only a small sample of the assemblage was analyzed, it is likely that more raw material source areas were used during the Archaic occupations of the site. Nonetheless, the resulting raw material networks are similar to those of the Megantic Lake region, with a strong representation of Kineo-Traveller rhyolite and Appalachian cherts. Great Lakes cherts are also present, as is Cheshire quartzite. Local silicified mudstone and quartz are weakly represented in the sample, though this is likely an effect of source proximity resulting in the near absence of completed forms made of local raw materials. The technical analysis of the sample, without control for techno-economic practices, denotes many technical recurrences within typological groupings, with no significant and recurring differences between raw materials of different source regions. Due to sample size and to the disturbed context, the significance of objects linked due to similarities in technique is doubtful. Interpersonal segmentation of operational sequences could not be determined, though the evidence appears to point towards the circulation of raw materials in multiple forms. It is to be assumed that, outside of the locally obtained raw materials, the occupants of the Gaudreau may not have had a direct access to any of the exogenous sources.

A presente dissertação expõe os resultados provenientes da pesquisa desenvolvida junto ao Projeto Arqueológico Quebra Anzol - MG, a qual versa sobre o estudo das cadeias operatórias e sistema tecnológico relacionado às indústrias líticas provenientes dos sítios ATM-691, localizado no Município de Tupaciguara - MG, Novo 1, Novo 2, Canindé e Buraco Seco, localizados no Município de Monte Alegre de Minas - MG, além de uma correlação junto aos dados que dizem respeito às ocupações mais recuadas do sítio Rezende, este localizado no município de Centralina - MG, em todos os casos caracterizados como sítios a céu aberto tocantes a contextos de ocupações de populações com economia extrativista de provisão relacionada às atividades de caça, coleta e pesca e que tem como único remanescente sua cultura material lítica. Pelo viés da tecnológica lítica, tivemos como principal objetivo analisar as dinâmicas socioculturais em sua compreensão intrassítio, de modo realizar um estudo pormenorizado dos sítios arqueológicos numa perspectiva da análise da cadeia operatória e sistema tecnológico dos vestígios líticos, bem como a análise inter-sítio, que visa à correlação dos dados obtidos no estudo dos cinco sítios propostos junto aos dados de outro sítio já estudado na região, de modo que foi possível verificar possíveis permanências e mudanças culturais manifestadas por meio da tecnologia presente nos conjuntos artefatuais oriundos das dinâmicas de populações caçadoras-coletoras, o que nos permitiu conceber um modelo empírico regional de ocupação baseado na caracterização da paisagem, economia de aprovisionamento, organização social e tipificação da tecnologia lítica para o médio vale do Paranaíba. / The Archaeological Project Quebra Anzol - MG, which deals with the study of the operative chains and technological system related to the lithic industries from the ATM- 691 sites, located in the municipality of Tupaciguara - MG, Novo 1, Novo 2, Canindé and Buraco Seco, located in the municipality of Monte Alegre de Minas - MG, in addition to a correlation with the data referring to the most backward occupations of the Rezende site, located in the Municipality of Centralina - MG, in all cases characterized as open - air sites touching contexts of occupations of populations with extractive economy of provision related to the activities of hunting, gathering and fishing and that has as its only remaining material lytic culture. The main objective of this study was to analyze the sociocultural dynamics in its intra-site understanding, so as to carry out a detailed study of the archaeological sites from the perspective of the analysis of the operative chain and the technological system of the lithic vestiges, as well as the inter-site analysis, which aims to correlate the data obtained in the study of the five sites proposed together with the data of another site already studied in the region, so that it was possible to verify possible permanences and cultural changes manifested through the technology present in the artifactual ensembles derived from the dynamics of hunting populations which allowed us to conceive a regional empirical model of occupation based on the characterization of the landscape, economy of supply, social organization and typification of lithic technology for the middle valley of Paranaíba

O objetivo do presente trabalho é o estudo da tecnologia de produção artefatual lítica lascada e suas cadeias operatórias em sítios líticos a céu aberto localizados no nordeste do Estado de São Paulo. Inicialmente foi levantada a bibliografia amadora e especializada dentro da área de estudo, dedicando atenção às tecnologias líticas produtivas e procurando nelas tópicos como preferências locacionais dos sítios líticos e os tipos de matérias-primas e seus suportes; em outras palavras, as economias de matéria-prima levadas a cabo pelos artesãos. Todo o aporte teórico-metodológico do conceito de cadeia operatória foi empregado, inclusive buscando-se o gestual dos artesãos - análise diacrítica, tentando reconstruir por meio do processo operatório e seu gestual o projeto mental do artesão, que se encontra sob uma matriz técnica, a tradição cultural. Por fim apresentamos os resultados das análises alcançados, sintetizando as cadeias operatórias praticadas e ilustrando os artefatos líticos por meio de croquis. Embora tenham sido estudados diretamente os artefatos líticos, com atenção a seus atributos técnicos, é fato que representam mais do que um contexto particular, e propiciam, mesmo que indiretamente, a possibilidade de que todo um sistema de sítios venha a ser pensado. / The main objective of this research is the study of the production technology of chipped stone artifacts and their operational sequence on lithic archaeological sites located in Northeastern São Paulo State. A bibliographic research was made based, firstly, on the amateur and specialized archaeological literature related to this specific subject, paying attention to the lithic production technology and looking for different topics such as locational preferences of the archaeological sites and the types of raw materials and their supports, in other words, the raw materials economy chose by the artisans. All methodological and theoretical operational sequence (\"chaîne opératoire\") was used, including the search for the artisans\' gestures - a diacritical analysis, intending to reconstruct through the operational processes and the gesture sequence the artisans\' mental project, related to a technical matrix - their technical tradition. Finally, the analytical results are presented, summarizing the operational sequences and illustrating lithic artifacts with drawings. Although lithic artifacts had been studied directly, focusing attention on its technical attributes, it is known that they represent more than a particular context, they may provide, even indirectly, interpretations about a whole system of sites.

Le territoire belge est caractérisé par de nombreuses découvertes de Préhistoire ancienne, réparties sur un espace géographique restreint mais contrasté en termes de relief et de disponibilité des ressources minérales. Il est donc favorable à létude de la relation de lHomme à son Environnement par le biais des importantes différences régionales relatives aux types de sites représentés (grottes/plein air) ainsi quà la proximité et à la morphologie du silex disponible. Le rapport entre les populations néandertaliennes et chacun des types denvironnements rencontrés constitue le cur de ce travail, structuré en quatre parties intimement liées. La première partie est consacrée aux variations environnementales. Celles du substrat dabord, puisque quelques kilomètres à peine séparent les plaines riches en silex de Moyenne Belgique des profondes vallées de Haute Belgique. Variations chronologiques ensuite, puisque la sédimentation quaternaire eut une incidence tant sur laccessibilité des ressources lithiques que sur la préservation des traces archéologiques qui nous sont parvenues. Lhistorique des recherches est aussi abordé car les motivations et les contraintes des chercheurs qui se sont succédés depuis 1829 sont largement responsables de labondance mais aussi de la qualité très variable des documents. La deuxième partie concerne cette documentation. Nous avons identifié 437 lieux, inégalement répartis sur le territoire, qui ont livré des artefacts relatifs au Paléolithique moyen : 46 sites en contexte karstique (dont 16 majeurs) et 391 en plein air (dont 31 majeurs). Leur distribution tient tant à des paramètres taphonomiques et aux circonstances des découvertes quà des choix opérés par les Néandertaliens eux-mêmes. Deux environnements sont particulièrement favorisés : les plaines dont le substrat livre un silex abondant et les grottes du Bassin mosan. Lexamen de la position topographique des gisements montre des récurrences traduisant des choix liés à limplantation dans le paysage : les plateaux ou le haut des versants surplombant de petites vallées sont ainsi clairement privilégiés. La distribution chronologique des traces est aussi abordée, mettant notamment en évidence labondance de la documentation relative au Début Glaciaire weichselien, labsence de véritable occupation durant le Pléniglaciaire weichselien inférieur ainsi quune concentration de traces attribuables au Pléniglaciaire weichselien moyen tout à fait exceptionnelle pour le Nord-Ouest européen. En létat actuel des données, les datations situent les industries les plus récentes du Paléolithique moyen vers 38.000 B.P. (grotte Scladina) et les derniers Néandertaliens vers 36.000 B.P. ( Bètche-aux-Rotches à Spy). La troisième partie consiste en une étude approfondie dune dizaine dindustries lithiques dépendant de contextes environnementaux variés. Plusieurs tendances générales sen dégagent dans la manière dont les populations paléolithiques ont adapté leurs systèmes dacquisition et dexploitation des roches. Ainsi, des variations claires se marquent dans les systèmes dacquisition des roches exploitées selon un gradient nord-est sud-ouest. En Basse Belgique, lemploi de galets de silex local est couplé à limportation de nucléus et d'éclats provenant de Moyenne Belgique. En Moyenne Belgique, le silex disponible localement est employé prioritairement et le recours à dautres roches locales ou importées est tout à fait exceptionnel. En Haute Belgique, limportation de silex depuis la Moyenne Belgique combinée au recours à dautres matériaux disponibles localement constitue la règle. Ces variations dans les systèmes dacquisition génèrent de la diversité en termes de nature, de morphologie, de conditionnement et de disponibilité des matériaux mis en uvre par les tailleurs. Ces différents paramètres ont une incidence sur les choix techniques posés par les Néandertaliens lors de la phase de débitage. Sobservent ainsi des différences régionales importantes. Les sites de Haute Belgique procèdent doptions économiques qui se manifestent tant dans la réduction des blocs, comme au Trou du Diable à Hastière, que dans ladaptation des concepts de débitage à tel point quils en deviennent parfois atypiques comme lattestent les nombreux remontages de la grotte Scladina. À linverse, les sites de Moyenne Belgique témoignent dun usage dispendieux de la matière première et dune expression des concepts Levallois, Discoïde et Laminaire dans leur acception la plus stricte comme le montrent notamment les industries du gisement paléolithique dOtrange ou dObourg Canal. La quatrième partie est consacrée à une discussion des résultats et à une ouverture sur le reste de lEurope. Cette disparité des productions liée à la position géographique des gisements est particulièrement importante : des sites voisins mais diachroniques (couches 5 et 1A de la grotte Scladina) présentent entre eux plus danalogies que dautres pénécontemporains mais dépendant denvironnements contrastés (couches 1A de la grotte Scladina et WFL de Veldwezelt-Hezerwater). Dautres facteurs de variabilité se surimposent à cette diversité régionale : fonction des sites, traditions culturelles et techniques, variations paléoenvironnementales, chronologie. Des comparaisons sont opérées avec les résultats obtenus dans les régions limitrophes de la Belgique mais aussi à plus grande distance, des similitudes comportementales étant observées dans le sud de lEurope, dans des environnements qui évoquent par certains aspects le karst des vallées du Bassin mosan. Belgium is noted for its many ancient prehistoric sites which are spread over a limited geographic area. Despite its limited size, this area shows important regional contrasts in terms of topographic relief and availability of mineral resources. These factors in conjunction with important regional differences related to the types of sites represented (cave/open air) as well as the proximity and morphology of the available flint make this area favorable for the study of man's relationship with his environment. The connection between the Neanderthal populations and the types of environments encountered constitutes the focus of this study which is divided into four closely associated parts. The first part is devoted to environmental variation starting with the interface between the flint-rich plains of Middle Belgium and the deep valleys of Upper Belgium. Only a few kilometers separate these two contrasting environments. Chronological variations follow because quaternary sedimentation had as much impact on the accessibility of lithic resources as on site preservation. The history of the research from 1829 to the present is also addressed. The motives and constraints of the researchers are responsible for both the abundance of documentary evidence and for the extremely variable quality of these documents. The second part concerns the previously mentioned documentation. Artifacts attributable to the Middle Paleolithic have been recovered from 437 sites : 46 sites (16 major ones) are found in karstic contexts and 391 sites (31 major ones) are open air sites. The distribution of these sites is a direct result of taphonomic processes, circumstances of discovery, and choices made by the Neanderthals themselves. In particular, two environments were favored : the plains which have abundant flint resources and the caves of the Mosan Basin. Prehistoric Man's choice of sites appears to be linked to topographical position : plateaus or cliff tops overhanging small valleys were preferred. Chronological distribution is also examined. It notably shows an abundant documentation from the Beginning of the Weichselian Pleniglacial and an absence of occupation during the Lower Weichselien Pleniglacial It also shows a concentration of archaeological evidences related to the Middle Weichselian Pleniglacial which is very exceptional for Northwest Europe. Based on research to date, Scladina Cave (38.000 B.P.) gives the most recent date for Middle Palaeolithic industries and Betche-aux-Rochtes at Spy (36.000 B.P.) provides the date for the last Neanderthals. The third part consists of a detailed study of ten lithic industries and their environmental context. Several general tendencies were detected in the way Palaeolithic populations adapted their systems of acquisition and exploitation of rocks. Clear variations in the systems of acquisition and exploitation along a northwest/southeast gradient were noted. In Lower Belgium, the use of local flint pebbles was coupled with the importation of nuclei and flakes from Middle Belgium. In Middle Belgium, the available local flint was used almost exclusively. Recourse to other local rocks or to imports was very exceptional. In Upper Belgium, the importation of flint from Middle Belgium in combination with other locally available materials constituted the rule. These variations in the systems of raw material procurement generated diversity in terms of nature, morphology, conditioning, and availability of the nodules chosen by the knappers. These diverse parameters impacted the technical choices of the Neanderthals during the reduction or debitage stage. Other important regional differences were also observed. The sites of Upper Belgium exhibited economic options which manifested in the reduction of blocks (Trou du Diable at Hastière) and in extreme adaptations or manipulation of concepts of reduction such as those recognized in several refittings from Scladina Cave. The sites of Middle Belgium exhibited an extravagant use of the primary material and a strict expression of different concepts : mainly Levallois, also Discoid, and volumetric blade production (gisement paléolithique d'otrange, Obourg Canal). The fourth part is devoted to a discussion of the results and a preliminary comparison to the rest of Europe. The connection of the diversity in lithic productions and the geographic position of the sites is particularly important. Lithic industries from the two occupation layers of Scladina (layers 5 and 1A) present more analogies between themselves than other plenicomtemporaneous sites in different environments (lays 1A of Scladina and WFL of Veldwezelt-Hezerwater). Other factors of variability superimpose themselves in this diverse region : function of the sites, cultural traditions and techniques, palaeoenvironmental variations, chronology. Comparisons with the results obtained from regions bordering Belgium as well as those obtained from greater distances showed some behavioural similarities in southern Europe in environments which evoke aspects of the karst valleys of the Mosan Basin.

Ce projet de recherche tente de mieux comprendre le phénomène des supports sur plaquette en quartzite du site ElFs-010 situé en Jamésie. Aucun travail de cette ampleur n’avait encore été réalisé sur ce type d’outil. Il y avait donc un vide à combler. Afin de répondre le plus adéquatement possible à cette problématique, nous avons divisé notre travail en trois objectifs. Dans un premier temps, déterminer si les plaquettes en quartzite sont le produit d’une technologie lithique ou bien d’un processus géologique naturel. En second lieu, démontrer si nous sommes en présence d’un épiphénomène propre au site ElFs-010. Finalement, définir si une période chronologique correspond à cette industrie. Les résultats de nos recherches nous démontrent que les supports sur plaquette en quartzite du site ElFs-010 se retrouvent naturellement sur le talus d’effondrement de la Colline Blanche. Leur faible épaisseur moyenne ainsi que leurs pans abrupts ont sans doute été les facteurs qui ont le plus influencé leur sélection. En nous basant sur ces deux caractéristiques, nous suggérons qu’ils auraient pu être utilisés comme des lames interchangeables ou bien des burins. Nous avons recensé 33 sites jamésiens qui comportaient au moins un fragment de plaquette en quartzite. Malgré quelques indices archéologiques, il est encore trop tôt pour affirmer que cette industrie est diagnostique d’un groupe culturel jamésien. Les données chronologiques suggèrent que cette industrie a connu un essor vers 1300 ans A.A. De plus, il semble que les régions géographiques que nous avons attribuées aux sites correspondent à des séquences culturelles bien définies. Finalement, nos hypothèses portent sur des recherches futures concernant un ensemble d’événements qui, tout comme les supports sur plaquette en quartzite, sont révélateurs de changements dans le mode de vie des groupes préhistoriques de la Jamésie. Mots-clés : Archéologie, Jamésie, ElFs-010, Colline Blanche, plaquette en quartzite, technologie lithique. / This research project seeks to better understand the phenomenon of tabular quartzite tools from the archeological site Elfs-010. No detailed work had yet been carried out on this type of tool, leaving a void to fill. To respond as adequately as possible to this problem, we focused our work on three main objectives. First, determine if tabular pieces of quartzite were the product of a particular lithic technology or of a natural geological process. Second, evaluate whether we are dealing with a unique phenomenon that is specific to site Elfs-010. Third, and finally, define if a specific time period corresponds to this industry. The results of our research show that tabular pieces of quartzite from site Elfs-010 occur naturally on the talus slope of the Colline Blanche. Their low average thickness and their steep sides were probably the factors that most influenced their selection. Based on these two characteristics, we suggest they could be used interchangeably as blades or burins. We identified 33 Jamesian sites that had at least one fragment of tabular quartzite. Despite some archaeological evidence, it is still too early to say that this industry is diagnostic of a Jamesian cultural group. Our chronological data suggest that this industry flourished around 1300 years BP. In addition, it appears that the geographic areas that we have attributed to the sites correspond to culturally well-defined sequences. Finally, our proposed hypotheses for future research concern the events that took place around 1300 years BP and which, like the tabular pieces of quartzite, are indicative of changes in the lifestyle of prehistoric groups of the James Bay region. Keywords: Archaeology, James Bay, ElFs-010, Colline Blanche, tabular pieces, quartzite, lithic technology. / Réalisé en collaboration avec Arkéos Inc.

Les industries lithiques de l’Holocène moyen, entre 8.000 et 4.000 BP dans le centre et le nord-est du Brésil ont souvent été décrites non pas en fonction des caractères présents mais de ceux absents : absence de lesma (pièce façonnée unifacialement), absence de céramique. Les traits techniques spécifiques à la période sont difficiles à cerner à cause de la diversité des artefacts. Décrites comme peu élaborées ou simples, ces industries interrogent pourtant par leurs caractères extrêmement différents de ceux de la période antérieure. Des hypothèses liées à des facteurs externes ont été évoquées pour expliquer de tels changements dans la culture matérielle : changement climatique avec une forte modification de l’environnement, remplacement de la population par une nouvelle vague de peuplement. Toutefois, il est difficile d’évaluer les modalités de cette rupture tant les analyses sur des assemblages de la période sont peu nombreux. Nous proposons dans ce travail de caractériser les systèmes techniques de l’Holocène moyen et par ce biais aborder le phénomène de rupture technique avec le technocomplexe Itaparica. Deux assemblages lithiques de l’Holocène moyen ont été étudiés selon une approche techno-fonctionnelle : la Toca Nova do Inharé dans la Serra da Capivara (Piauí) et le site Cajueiro (BA-RC-19) au nord-est du plateau central (Bahia).Les résultats obtenus mettent en évidence l’existence de caractères partagés et de variabilités importantes. L’organisation des différentes parties fonctionnelles des outils, structurée par la présence récurrente de pans abrupts, constitue un caractère commun fort. Les supports d’outils sont en revanche très variables selon les sites, expliquant cette impression d’absence d’outils clairement définis déjà soulignée.La confrontation de nos résultats aux données disponibles dans la littérature nous a permis d’affirmer ces caractères comme une spécificité des industries de l’Holocène moyen et de confirmer également l’existence d’une rupture technique importante avec le technocomplexe Itaparica. / During middle Holocene, between 8000 and 4000 BP, central and northern Brazil lithic industries were often described in terms of lacks more than tangible characteristics: lacks of “lesma” (unifacial shaping tool), lacks of ceramics. Specific technical features linked to that period are not easy to pinpoint because of a high level of artifacts diversity. Described as somewhat elaborate or simple, the specific nature of these industries highlights differences between this period and the previous one. To explain such a change in material culture, external factor hypothesis were proposed: huge environment modification due to climate change, new population that replaces another one. However, it is uneasy to evaluate break modalities regarding few studies on these period assemblages.Our work proposes to characterize the technical systems for the middle Holocene, and, by this way, to broach the technical break phenomenon using Itaparica techno-complex. Two middle Holocene lithic assemblages were study in a techno-functional way: la Toca Nova do Inharé, in Serra da Capivara (Piauí) and the Cajueiro site (BA-RC-19) northeastern of the central plateau (Bahia). Results reveal shared characteristics and significant variability. Organization of different functional parts of tools outlined around recurrent presence of abrupt sides, form a strong shared feature. Tool blanks have, however, high degree of variability according to different sites, explaining the lack of strictly defined tools. Our results compared to available literature data allow us to confirm that these features are specific to these middle Holocene industries and also to bear out the existence of a significant technical break with the Itaparica techno-complex.
