Entre o mercado e a construção social: uma análise da experiência da implantação doPRONAF-infraestrutura e PRONAT nos territórios do Mato Grande-RN e sertão do Apodi-RN (1997 - 2010)

Analyzes the development experience in the Territories of Mato Grande and Sertão do Apodi in the state of Rio Grande do Norte, evaluating the actions of the National Program for Strengthening Family Agriculture, specifically the line of infrastructure (PRONAF-INFRA), and the National Program for Sustainable Development of Rural Territories (PRONAT) in these territories. Summarizes the various rural development approaches and takes the theoretical assumptions of territorial development, the concept of constructed territory and market-plan territory, further the cycle model to analyze public policies selected these experiences. Thus, we propose to test the hypothesis that most of the actions implemented would lead to the formation of market-plan territories, in other words, perceived only as a platform for the presentation of projects. The literature and documents, combined with case studies, interviews and direct observation of the meetings of committees, showed that, despite two boards are under the same laws, rules and formal regulations, have clear differences when considering the theory and concepts that were used as reference. The Apodi s territory is closer to a constructed space thus the search for a broader agenda, more autonomous and more appropriate to the reality experienced by local actors. On other hand the Territory of Mato Grande had the characteristics of a market-plan territory more present. As the result, the territory of Sertão do Apodi accesses not only as part of a greater number of policies and funding sources, ensuring a greater and more diverse investment volume than the territory of Mato Grande. Despite these differences, studies have shown that territorial boards surveyed are still far from becoming the main forum for managing the development from conception planning socially constructed. Showed, finally, that territorial development strategy is relevant, but requires a long walk and a deep and continuous learning process to be successfully implemented in rural areas of Northeast Brazil

Em cada canto, um conto, uma canção: o velho, a tradição oral e a educação no Mato Grande/RN

This dissertation is about an Education which is made concrete through orality and gestuality of the elderly joking masters of the territory of Mato Grande/RN and proposes a reflection about the exchange between these two knowledges and school education. Thus, it presents the following objectives: identifying the joking elderly in the region; recording their life experiences related to the jokes of the tradition and the way they realize such references at present; besides investigating and recording educative practices which consider the elderly s jokes at the present education. The investigation is supported by the metaphor in the making of a quilt as a methodological resource in the actions of measurement, choice of patches, sewing and binding off. The mapping of the territory of Mato Grande/RN has enabled the identification of seventeen joking elderly people. It considers and records their experiences with the popular amusements and from them, it discusses the ways through which the oral tradition in Mato Grande may be recognized in four categories/actions, namely, narrating, singing, dancing and getting old, which are analyzed under the studies by authors like Benjamin, Zumthor, Almeida, Porpino, among others. Finally, it also focuses the relation between the elderly, the knowledge of the tradition and the systemized education. It describes and articulates educative actions able to connect the knowledge by the joking elderly people and the knowledges taught at school, possibilities of concretization of a rebinding of knowledges which might bring orality and writing, the new and the old, science and tradition close to each other

Gênero, trabalho e saúde mental entre trabalhadoras rurais assentadas na região do Mato Grande Potiguar

The lack of studies aimed at the mental health of the rural population, the social, economic, familial and emotional impact that mental disorders produce and the vulnerability that women have in this context, lead us to believe in the need to investigate the mental health demands of female rural workers, in order to subsidize the development of more effective and culturally sensitive public health programs and policies that take into account the specificities of this population. The present study aims to investigate the prevalence of common mental disorders (CMD) and the possible factors associated with the emergence of such disorders among women living in a rural settlement in Rio Grande do Norte. This survey has a quantitative and qualitative character with an ethnographic approach. As methodological strategies, we made use of an adapted version of the socio-demographic and environmental questionnaire prepared by The Department of Geology/UFRN s Strategic Analysis Laboratory to evaluate the quality of life of the families from the rural settlement and the mental health screening test Self-Reporting Questionnaire (SRQ-20) to identify the prevalence of CMD in adult women from the community. Complementing the role of methodological tools, we use the participant observation and semi-structured interviews with women who presented positive hypothesis of CMD attempting to comprehend the crossings that build the subjective experience of being a woman in this context. The results point to the high prevalence of CMD (43.6%) and suggest the link between poverty, lack of social support, unequal gender relations and the occurrence of CMD. We also verified that the settled women do not access the health network to address issues relating to mental health and that the only recourse of care offered by primary health care is the prescription of anxiolytic medication. In this context, the religiosity and the work are the most important strategies for mental health support among women

Dançando, cantando e contando histórias, os velhos do Mato Grande/RN educam através dos gestos e da oralidade

Compartilho fragmentos da dissertação que trata de uma Educação que se concretiza na oralidade e na gestualidade dos velhos mestres brincantes do território do Mato Grande/RN e propõe uma reflexão sobre o trânsito entre esses saberes e a educação escolar. Assim, assume os seguintes objetivos: identificar os velhos mestres brincantes da região do Mato Grande, registrar suas experiências de vida relacionadas às brincadeiras da tradição e o modo como os mesmos percebem essas referências na atualidade, investigar e registrar práticas educativas que considerem as brincadeiras dos velhos na educação atual. Assim realiza um mapeamento do território do Mato Grande/RN a partir do qual identifica dezessete velhos brincantes. Considera e registra suas experiências com os folguedos populares e a partir desses registros passa a discutir os modos pelos quais a tradição oral do Mato Grande pode ser reconhecida a partir das ações: narrar, cantar e dançar. Por último, lança um olhar para a relação entre o velho, o conhecimento da tradição e a educação sistematizada

Gato-do-mato-pequeno (Leopardus tigrinus) na Caatinga: ocupação e padrão de atividade de um felídeo ameaçado e pouco conhecido na floresta tropical seca do nordeste do Brasil

While the carnivores are considered regulators and structuring of natural communities are also extremely threatened by human activities. Endangered little-spotted-cat (Leopardus tigrinus) is one of the lesser known species from the Neotropical cats. In this work we investigate the occupancy and the activity pattern of L. tigrinus in Caatinga of Rio Grande do Norte testing: 1) how environmental and anthropogenic factors influence their occupation and 2) how biotic and abiotic factors influence their activity pattern. For this we raised occurrence data of species in 10 priority areas for conservation. We built hierarchical models of occupancy based on maximum likelihood to represent biological hypotheses which were ranked using the Akaike Information Criterion (AIC). According to the results the feline occupancy is more likely away from rural settlements and in areas with a higher proportion of woody vegetation. The opportunistic killing of L. tigrinus and in retaliation for poultry predation close to residential areas can explain this result; as well as more complex vegetation structure can better serve as refuge and ensure more food. Analyzing the records of the species through circular statistics we conclude that the activity pattern is mostly nocturnal, although considerable crepuscular and a small diurnal activity. L. tigrinus activity was directly affected by the availability of small terrestrial mammals, which are essentially nocturnal. In addition, the temperatures recorded in the environment directly and indirectly affect the activity of the little-spotted-cat, as also influence the activity of their potential prey. Generally, the cats were more active when possible prey were active, and this happened at night when lower temperatures are recorded. Moreover, the different lunar phases did not affect the activity pattern. The results improve the understanding of an endangered feline inhabiting the Caatinga biome, and thus can help develop conservation and management strategies, as well as in planning future research in this semi-arid ecosystem.

Genotoxicidade e composição do material particulado emitido pela queima de Biomassa: um estudo de caso em Tangará da Serra, Região da Amazônia Brasileira

Tangara da Serra is located on southwestern Mato Grosso and is found to be on the route of pollutants dispersion originated in the Legal Amazon s deforestation area. This region has also a wide area of sugarcane culture, setting this site quite exposed to atmospheric pollutants. The objective of this work was to evaluate the genotoxicity of three different concentrations of organic particulate matter which was collected from August through December / 2008 in Tangara da Serra, using micronucleus test in Tradescantia pallida (Trad-MCN). The levels of particulate matter less than 10μm (MP10) and black carbon (BC) collected on the Teflon and polycarbonate filters were determined as well. Also, the alkanes and polycyclic aromatic hydrocarbons (PAHs) were identified and quantified on the samples from the burning period by gas chromatography detector with flame ionization detection (GC-FID). The results from the analyzing of alkanes indicate an antropic influence. Among the PAHs, the retene was the one found on the higher quantity and it is an indicator of biomass burning. The compounds indene(1,2,3-cd)pyrene and benzo(k)fluoranthene were identified on the samples and are considered to be potentially mutagenic and carcinogenic. By using Trad-MCN, it was observed a significant increase on the micronucleus frequency during the burning period, and this fact can be related to the mutagenic PAHs which were found on such extracts. When the period of less burnings is analyzed and compared to the negative control group, it was noted that there was no significant difference on the micronuclei rate. On the other hand, when the higher burning period is analyzed, statistically significant differences were evident. This study showed that the Trad-MCN was sensible and efficient on evaluating the genotoxicity potencial of organic matter from biomass burning, and also, emphasizes the importance of performing a chemical composition analysis in order to achieve a complete diagnosis on environmental risk control

A encruzilhada da vida política em assentamentos de reforma agrária no Rio Grande do Norte

The rural settlements represent a mark in the expensive historical process of fight by the land in Brazil. At first offer basic terms of survival, through the access the land and of the fundamental supports for exploration. At the same time, have stimulated organization forms politicizes of the families who manage to work with the new challenges of the everyday. The moment that follows the land conquest, and therefore, the settlements construction while life and work project, it is crossed for objective and subjective demands, with highlight for options of agricultural production and strategies of collective action. Originally formed as representation instance legitimates of the families - front to the government and social actors - the settlers associations are private spaces for political sociability, that guided by principles participative, can lead the settlers the new conquests through indeed democratic experiences. The goal of this work is to comprehend the participation forms in the scope of these associations and the way as that translates in life best terms for the group, from the settlements experiences located in the Territories of the Citizenship Mato Grande and Açu-Mossoró, in Rio Grande do Norte's State. The theoretical conceptions that guide this analysis are concentrate on discussions about democracy and participation (Patermam, Putnam, Bodernave) and in the reflections about the rural world (Medeiros, Martins, Woodman e Woodman and Bergamansco). About methodological, different point of view strategies were developed: The direct observation, the application in locate of questionnaires to the families settlers and interviews semi-structured with the internal leaderships. With that could verify that the participation forms in the associations operate in two heartfelt: Of a side, they promote assimilation opportunities of democratic abilities accompanied of notions of social rights and redefinition of political standards; Of another, it offers indeed the possibility of the settlers lead, with relative autonomy, the political organization and her changes in direction to a way of life that wish to have in the settling

IMPASSES, DESAFIOS E BROTOS: O papel da Assessoria na Transição Agroecológica em Assentamentos Rurais

This thesis is the result of a study on the role of technical assistance in the process of agroecological transition, which are under way in rural settlements in the territory of Mato Grande, Rio Grande do Norte. Your goal is, from the Technical Assistance Program, Social and Environmental (ATES), launched in 2004 by INCRA understand to what extent this action accomplished their goal of doing a job with a focus on agroecology. To this end, we chose to work with a qualitative methodology, through interviews with settlers, advisors and representatives of INCRA. They also contributed to developing this thesis, the direct observations, which offer visits to settlements and advisory bodies in the Rede Pardal, apart from participation in meetings and activities in which they were being discussed the issues of advice, agroecology and rural settlements. The thesis is divided into five chapters, plus introduction and conclusion. The first three refer to a theoretical analysis and historical about the process of land reform, and as a result the establishment of rural settlements, the importance of peasant tradition for the design of agro-ecological design and the relationship between agricultural models and proposals advice to the countryside. In two subsequent chapters, there was a panoramic picture of the territory of Mato Grande, settlements and groups that make up this research, for then analyze the performance of advisory services in these settlements, with the parameter, agroecology. It was found that the advice in this perspective, suffers a series of constraints, causing a gap between the ideal proposed in the manual and the actual practiced in their daily lives. Still, it is concluded that the ATES has contributed to innovations in productive groups who are experiencing agroecological processes, which can be regarded as shoots for the transition to a new dynamic of development.

Instituições, agricultura familiar e crédito rural: avaliação de resultados do Pronaf B nos territórios rurais do Rio Grande do Norte

Broadly anchored on Institutionalist literature this dissertation seeks to answer: Why rural credit granted to farming families in Rio Grande do Norte, Pronaf group B, has shown positive results in some territories while in others the same results are insatisfactory? Considering formal rules are the same, then why such results are so distinguished? This research supports the fact that these results are a direct consequence of the quality of institutions defined as longstanding social rules established and built in social interactions. For institutions one understands; organizational structures, formal and non-formal rules, social trust, thinking behaviors and its evolution as well as routines. Using Pronaf Rural Credit as a background this study measures and compares results obtained in the rural areas of Seridó, Sertão do Apodi, Mato Grande, Assú-Mossoró, Trairi, Potengi and Alto Oeste. The dimensions of measurement considered were: economics, social and guarantee of transparency. The study considers a sample of 402 Group B farming families. It also elaborates a socio-economic profile of these families in the considered areas and underlines the main causes for defaulted loans, difficulties to improve family income and results of access to Pronaf B credit line, as well as it proposes solutions to surpass obstacles to improve the efficiency of this credit line

Políticas públicas para agricultura familiar: uma avaliação sobre a correspondência do paa e do PRONAF nos territórios da cidadania do Rio Grande do Norte - 2008 a 2010.

Family farming has been considered as the new axis of rural development in the country, the focus of several public policies, especially the National Program for Strengthening Family Agriculture - PRONAF and Food Purchase Program - PAA. PRONAF was created with the aim of providing credit to farmers, while the PAA to support family farmers through the purchase of its production. In this context, the objective of this study is to analyze the correspondence of these two public policies for family farming, in the Territories of Citizenship of the state of Rio Grande do Norte, between the years 2008 to 2010. In the methodology, the analysis was performed by comparing the distributions of the two programs in the territories of citizenship status. There were also statistical tests of differences in proportions, and Spearman correlations, and estimated a logit regression model, in order to measure the probability of a farmer participating in the PAA is associated with one of the modes of PRONAF. The data used were obtained from the National and Supply - CONAB at the Institute of Technical Assistance and Rural Extension - EMATER, and the Ministry of Agrarian Development - MDA. Among the key findings was noted that policies were associated with a direct, but low in the districts of the Territories of Citizenship. And that, in the years 2008 and 2009, only in the territories of Mato Grande, Alto Oeste and Seridó, the actions of PAA and PRONAF had direct and significant correlations. It was found that in most of the territories, policies are performed randomly, ie that both have no correlation to each other. The estimates of the logit model showed that the chance of a family farmer, the PAA participant, receive credits PRONAF A, is higher in the territory of Mato Grande, and would have a chance to fall in PRONAF B in all areas surveyed. Moreover, farmers in the territories of the Assu-Mossoró, Sertão of Apodi, Seridó and Alto Oeste, participating in the PAA would be more likely to receive credits PRONAF C, reflecting thus the family farm more consolidated these territories

Uma sequência didática a partir da temática terremotos com ênfase em CTS

Throughout its history the population of the region of Mato Grande, which includes the city of João Câmara, in Rio Grande do Norte, was subject to earthquakes. These events are caused by a geological fault, known as fault Samambaia. In the 1980s there was an intensification of this phenomenon culminating in an earthquake 5.1 on the Richter scale in the early hours of November 30, 1986, causing researchers from Brazil and other countries to shift to the region to conduct research in Seismology. During this period there was a strong interaction between scientists and local people. With the aim of studying how people experienced that moment that marked the history of the city of João Câmara, from interviews with some individuals who witnessed the incident, is that this research was developed. Taking as a theoretical approach to Science, Technology and Society (STS), aimed to thus carry the theme in a systematic way to the classroom, promoting ways to help teachers with the scientific training and guidance to students in case of occurrence of earthquakes

Adaptabilidade de híbridos entre Gossypium barbadense E G. hirsutum N contendo o gene cry1Ac

Hybrids among transgenic plants and related species are expected to occur if they are sympatric and when there are not crossing barriers; as is the case, in Brazil, of cry1Ac transgenic cotton and Gossypium barbadense. This species has been maintained as dooryard plants, and should be preserved as a genetic resource. Hybrids were evaluated about traits related to fitness, leading to infer about its chances of survivor and selection. A barbadense genotype collected at the state of Mato Grosso was outcrossed to the variety DP 404, containing the gene cry1Ac, and to the isoline DP 404. All the F1 individuals and 122 among 170 F2 individuals expressed the toxin, and presented levels of resistance to pink bollworm (Pectinophora gossypiella) and cotton leafworm (Alabama argillacea) equivalent to the transgenic parent and superior to the isoline, barbadense or non transgenic hybrids. The percentage of germination and number of days to germinate did not differ among genotypes. Anthesis of the first flower and opening of the first cotton boll occurred earlier for herbaceous cotton and F1 hybrids than F2 population in average; all the populations presented a number of days to flower and opening of the first boll smaller then barbadense. The highest plants were barbadenses, and herbaceus the smallest, with F1 and F2 populations presenting intermediary heights. The number of seeds per plants were superior for F1 hybrids an herbaceous cotton, F2 populations were in average intermediary; the barbadense genotype produced the smallest number of seeds per plant. Pink bollworm, mainly, and also cotton leafworm, are important barbadense pests, so the transgene positive effect could favor the selection of hybrids, and hence G. hirsutum genome, against the maintenance of pure G. barbadense genome. The selection may be influenced by the plant uses: the smaller size of hybrids when compared to the barbadense may lead them to be differentiated from these parents to which medicinal properties are attributed; on the other hand, the greater boll production may favor hybrids maintenance with the purpose of producing lamp wicks, or use as an ornamental or swab

Detecção de predadores por dicromatas e tricromatas humanos e a sua implicação na evolução da visão de cores em primatas

Among placental mammals, primates are the only ones to present trichromatic color vision. However, the distribution of trichromacy among primates is not homogeneous: Old World primates shows an uniform trichromacy (with all individuals being trichromats) and New World primates exhibit a color vision polymorphism (with dichromatic males and dichromatic or trichromatic females). Visual ecology studies have investigated which selective pressures may have been responsible for the evolution of trichromacy in primates, diverging from the dichromat standard found in other mammals. Cues associated with foraging and the socio-reproductive status were analyzed, indicating a trichromatic advantage for the rapid detection of visually conspicuous objects against a green background. However, dichromats are characterized by an efficient capture of cryptic and camouflaged stimuli. These advantages regarding phenotype may be responsible for the maintenance of the visual polymorphism in New World primates and for the high incidence of color blindness in humans (standing around 8% in Caucasian men). An important factor that has not yet been experimentally taken into account is the predation risk and its effect on the evolution of trichromacy in primates. To answer this question, we prepared and edited pictures of animals with different coats: oncillas (Leopardus spp.), puma (Puma concolor) and ferret (Galictis cuja). The specimens were taxidermized and the photographs were taken in three different vegetation scenarios (dense forest, cerrado and grassland). The images of the predators were manipulated so that they fit into two categories of stimulus size (small or large). After color calibration and photo editing, these were presented to 40 humans (20 dichromats and 20 trichromats) by a computer program, which presented a set of four photos at a time (one picture containing the taxidermized animal amid the background vegetation and three depicting only the background vegetation) and recorded the response latency and success rate of the subjects. The results show a trichromatic advantage in detecting potential predators. The predator detection was influenced by the background, the predator species, the dimension of the stimulus and the observer s visual phenotype. As humans have a high rate of dyschromatopsias, when compared to wild Catarrhini or human tribal populations, it is possible that the increased rate of dichromats is a result of reduced pressure for rapid predator detection. Since our species came to live in more cohesive groups and resistant to attack by predators, with the advent of agriculture and the formation of villages, it is possible that the lower risk of predation has reduced the selection in favor of trichromats

Litoestratigrafia e deformação cenzóica na região de Icapuí, Ceará, e implicações para a estruturação de campos de petróleo na borda ocidental da bacia Potiguar(NE do Brasil)

This thesis deals with the sedimentological/stratigraphic and structural evolution of the sedimentary rocks that occur in the NW continental border of the Potiguar Basin. These rocks are well exposed along coastal cliffs between the localities of Lagoa do Mato and Icapuí, Ceará State (NE Brazil). The sedimentological/stratigraphic study involved, at the outcrop scale, detailed facies descriptions, profile mapping of the vertical succession of different beds, and columnar sections displaying inferred lateral relationships. The approach was complemented by granulometric and petrographic analyses, including the characterization of heavy mineral assemblages. The data set allowed to recognize two kinds of lithological units, a carbonate one of very restricted occurrence at the base of the cliffs, and three younger, distinct siliciclastic units, that predominate along the cliffs, in vertical and lateral extent. The carbonate rocks were correlated to the late Cretaceous Jandaíra Formation, which is covered by the siliciclastic Barreiras Formation. The Barreiras Formation occurs in two distinct structural settings, the usual one with nondeformed, subhorizontal strata, or as tilted beds, affected by strong deformation. Two lithofacies were recognized, vertically arranged or in fault contacts. The lower facies is characterized by silty-argillaceous sandstones with low-angle cross bedding; the upper facies comprises medium to coarse grained sandstones, with conglomeratic layers. The Tibau Formation (medium to coarse-grained sandstones with argillite intercalations) occurs at the NW side of the studied area, laterally interlayered with the Barreiras Formation. Eolic sediments correlated to the Potengi Formation overly the former units, either displaying an angular unconformity, or simply an erosional contact (stratigraphic unconformity). Outstanding structural features, identified in the Barreiras Formation, led to characterize a neocenozoic stress field, which generated faults and folds and/or reactivated older structures in the subjacent late cretaceous (to paleogene, in the offshore basin) section. The structures recognized in the Barreiras Formation comprise two distinct assemblages, namely a main extensional deformation between the localities of Ponta Grossa and Redonda, and a contractional style (succeeded by oblique extensional structures) at Vila Nova. In the first case, the structural assemblage is dominated by N-S (N±20°Az) steep to gently-dipping extensional faults, displaying a domino-style or listric geometry with associated roll-over structures. This deformation pattern is explained by an E-W/WNW extension, contemporaneous with deposition of the upper facies of the Barreiras Formation, during the time interval Miocene to Pleistocene. Strong rotation of blocks and faults generated low-angle distensional faults and, locally, subvertical bedding, allowing to estimate very high strain states, with extension estimates varying between 40% up to 200%. Numerous detachment zones, parallel to bedding, help to acommodate this intense deformation. The detachment surfaces and a large number of faults display mesoscopic features analoguous to the ones of ductile shear zones, with development of S-C fabrics, shear bands, sigmoidal clasts and others, pointing to a hydroplastic deformation regime in these cases. Local occurrences of the Jandaíra limestone are controled by extensional faults that exhume the pre-Barreiras section, including an earlier event with N-S extension. Finally, WNWtrending extensional shear zones and faults are compatible with the Holocene stress field along the present continental margin. In the Vila Nova region, close to Icapuí, gentle normal folds with fold hinges shallowly pluging to SSW affect the lower facies of the Barreiras Formation, displaying an incipient dissolution cleavage associated with an extension lineation at high rake (a S>L fabric). Deposition of the upper facies siliciclastics is controlled by pull-apart graben structures, bordered by N-NE-trending sinistral-normal shear zones and faults, characterizing an structural inversion. Microstructures are compatible with tectonic deformation of the sedimentary pile, burried at shallow depths. The observed features point to high pore fluid pressures during deformation of the sediments, producing hydroplastic structures through mechanisms of granular flow. Such structures are overprinted by microfractures and microfaults (an essentially brittle regime), tracking the change to microfracturing and frictional shear mechanisms accompanying progressive dewatering and sediment lithification. Correlation of the structures observed at the surface with those present at depth was tested through geophysical data (Ground Penetrating Radar, seismics and a magnetic map). EW and NE-trending lineaments are observed in the magnetic map. The seismic sections display several examples of positive flower structures which affect the base of the cretaceous sediments; at higher stratigraphic levels, normal components/slips are compatible with the negative structural inversion characterized at the surface. Such correlations assisted in proposing a structural model compatible with the regional tectonic framework. The strong neogenepleistocene deformation is necessarily propagated in the subsurface, affecting the late cretaceous section (Açu and Jandaíra formations), wich host the hydrocarbon reservoirs in this portion of the Potiguar Basin. The proposed structural model is related to the dextral transcurrent/transform deformation along the Equatorial Margin, associated with transpressive terminations of E-W fault zones, or at their intersections with NE-trending lineaments, such as the Ponta Grossa-Fazenda Belém one (the LPGFB, itself controlled by a Brasiliano-age strike-slip shear zone). In a first step (and possibly during the late Cretaceous to Paleogene), this lineament was activated under a sinistral transpressional regime (antithetic to the main dextral deformation in the E-W zones), giving way to the folds in the lower facies of the Barreiras Formation, as well as the positive flower structures mapped through the seismic sections, at depth. This stage was succeeded (or was penecontemporaneous) by the extensional structures related to a (also sinistral) transtensional movement stage, associated to volcanism (Macau, Messejana) and thermal doming processes during the Neogene-Pleistocene time interval. This structural model has direct implications to hydrocarbon exploration and exploitation activities at this sector of the Potiguar Basin and its offshore continuation. The structure of the reservoirs at depth (Açu Formation sandstones of the post-rift section) may be controlled (or at least, strongly influenced) by the deformation geometry and kinematics characterized at the surface. In addition, the deformation event recognized in the Barreiras Formation has an age close to the one postulated for the oil maturation and migration in the basin, between the Oligocene to the Miocene. In this way, the described structural cenario represents a valid model to understand the conditions of hydrocarbon transport and acummulation through space openings, trap formation and destruction. This model is potentially applicable to the NW region of the Potiguar Basin and other sectors with a similar structural setting, along the brazilian Equatorial Atlantic Margin
