Las relaciones de saberlos pedagógicos en la formación de enseñanza, el dirigir de la tesis, si presentes como ocasión de reflejar en saber básico pedagógico el profesor práctico a él, en especial a la formación de profesores. Se considera que con éstos que saben, el profesor adquiere sensibilidad para desarrollar su elemento formativo práctico. Su función principal es favorecer a la relación teoría práctica usándose, para el, de la reflexión como ocasión de concreción de las direcciones. Actuando en diversos cursos de la formación de enseñanza, el nivel de la graduación y algunas instituciones, fue parecido con situaciónproblemas cuál si está instigado, para buscar cada tiempo más para entender porqué en esos diversos contextos prácticos el pedagógico si está configurado diferentemente. Con propósito para entender las direcciones de los formadores de los profesores en cuanto a las relaciones de saberlas pedagógicos en la formación de enseñanza, la investigación se convierte en un continente académico - tres instituciones públicas de educación superior que actúan en el estado del gran río del norte - UFRN, UERN e IFESP. Los participantes de la investigación, entrevistadas con, de 12 profesores-formadores de funcionamiento de los cursos de las matemáticas (licenciatura), de Pedagogía y de normal superior de estas instituciones. Metodología pauta desarrollada en la entrevista comprensiva, el subir de metodológica de la naturaleza cualitativa, básica para interpretar las direcciones y los valores para ser explicitados en el acuerdo los discursos entrevistados. Finalmente, se considera que los cuatro saber si explique para la interrelación que poseen. Para saber para saber si une con para saber para hacer para dar y concebir la idea para hacer. Para saberlos para hacer y para saber se ha sentido solamente habrá tenido con quién a la parte para saber para coexistir. Para saber para ser él será solamente significativo frente las lecciones de los otros para saber. El formador va a redimensionar, gradualmente y concienzudo, cada uno de éstos a saber con la educación. La dirección de aprender se desarrolla en un proceso inverso a la educación, puesto que, el aprendiz, una época el saber a ser, sabe para coexistir con sus pares, sabe para hacer e. Finalmente, sabe para saber. A este movimiento puede ser llamado de sociointeracionismo. Toda esta mediación solamente sucede si el aprendiz sujeto, el estudiante o el profesor, es concienzudo de su desarrollo y de la transformación gradual de la educación y de la sociedad. Saberlos, las filas en práctico son, otra vez, conocimiento constituido desarrollado, complejo y transformado para rehacer el paso. De este modo, si percibe la necesidad de una base para saber destinado pedagógico al profesor y a los ayudadores prácticos de la formación continuada de profesores

This Study inserts in Mathematical Education & Education that search to investigate the (self) formation of formers that gets graduation e pass to graduate others that get graduation and are formers in Mathematical Education. This Is a qualitative search in a perspective from search-formation.The work is formed of four topics. First topic talks about : The self-formation of formers. Second topic: at way of suppositions theorical-methodological from search. Third topic tells over: The life of a former life. Fouth topic A Station called Ubiratan D´Ambrosio created in his reverence and for build all the Knowledge´s Corpus developed by his studies and searches. It´s in sense of come and go from knowledge created at action by mankind to get finality of Transcendency and Survive. Look for to investigate aspects of academical, professional and personal life where are translated in language, thinking and practices oriented for one know-how holistical and transdiciplined in a reflexion, search and the critical it constitute to be a Professor, Teacher, Searcher and Etnomathematic that confered him the merit in 2005 the Prize Félix Klein, that declared Valente (2007), maximum distinction that can receive someone from Mathematical Education. The results point that the narratives of life´s stories are prominences to one re-direction of teach practical in formation´s courses of Mathematical teachers, opening spaces for what the teachers and particularly of Mathematical thinking and take position about your process of formation to be Formers. The Study also given possibilities to propose fourteen stoppages in Station that are beginnings with direction that emerge from studies and searches about the trajectory of life of Professor Ubiratan D´Ambrosio in perspective of re-signify the formative process in education and Mathematical Education

This study, developed in conjunction to the Pedagogical Practice research line and the Curriculum of Post-graduation in Education Program of UFRN is about investigations on formation of professors and teaching knowledge. Its objective is to analyze fundamental concepts for lecturing and the relationship that establishes between those concepts and the practice of forming professors. We adopted as referential the principles of social-historical approach, in the context of concepts making and development (Vygotsky, Luria and Rubinstein), and of collaborative theoric-methodological approach (Jacullo-Noto, Kemmis and Ibiapina). Collaboration with professors was mediated by diary writing, collaborative observation and conceptual network creation, essential to perceiving the given meanings to concepts that sustain the practice of 06 (six) forming professors from the UFPI Pedagogy Course. Teresina Campus. This way, reflections with collaborator professors allowed to build conceptual networks, in which prominence was given to the meanings of concepts that gave sustaining to their lecturing practices in the referred course, showing a fragmentation and disarticulation between theory and forming practice. They also indicate a need to give new concepts to the meanings of teaching concepts, learning and lecturing of these professors, in a meaning of a greater understanding about those concepts for their effective practice. On the context of collaborative reflection about conceptual networks, it was evident the conflict generated between the meanings attributed by professors and the practice developed in class, pointing to the need of rethinking the articulation between theory and practice not only on the formative process developed, but also on the continual formation of forming professors and on the construction of discussing spaces and materialization of the curricular principles of the Pedagogy Course

This thesis describes and analyzes the trajectory of education of an educator-teacher group to become tutor of memorials (final work of the course Normal Superior in Instituto de Educação superior President Kennedy IFESP-Natal-RN). The writing of memorials (self-biographical writing) propitiates to the pupil that writes a reflection on his/her student and professional life, and to whom guides an evolution in his/her professional education. From the methodological point of view, we adopt an etnomethodological perspective of qualitative approach which describes the reality of real citizens inserted in a real situation of education. It is constituted of participants of the research of 32 educator-teachers, deriving of three different areas of academic formation. The instruments of data collection consist of eight life histories, 32 contextualization applications of the participants of the research, interviews with two consultants of the project, as well as some documents. The results of the analyses put in evidence that the education of the educator-teacher goes for two parallel ways: the first deals with the experiences, interactions and elements of daily practice; the second with the academy experiences where the educator-teacher searches the post-graduation courses. The integration of these two ways defines the educator-teacher identity with foundation in knowings that constitute in the exercise of guidance of memorials. The teachers knowings are considered insufficient by the majority and others knowings are mobilized to the knowing to be educator-teacher, memorial tutor. The thesis concludes that the trajectory of the educator-teacher constitutes an educator experience, in the direction of that implies an articulation among the learnings, abilities and knowings, to support the pupil in self-discovery, and that these multiple experiences favor the education of these teachers

This work analyses pedagogical practices of Adelle Sobral de Oliveira, from 1900 to 1940, in order to notice how her performance as educator and administrator took place in Externato Angelo Varela in the Rio Grande do Norte city of Ceará-Mirim within a time in which the public teaching started to be considered modern in the State. Adelle was a self learner who developed an important role as a mentality mentor of a generation in the region. As the research corpus we have taken the five Reading Books written by Felisberto de Carvalho used by Adelle in her Externato, interviews with her ex-students and researches in the newspapers of her time, in the Public Archives and in the Historical and Geographic Institute of Rio Grande do Norte, and also in the governors messages, Education Department documents such as laws, and government decrees and acts. It was also taken as a research font the Publich Archives of Ceará-Mirim. The aim of this PhD thesis is understand the primary instruction spreading and modernization in the countryside of Rio Grande do Norte, which began with her teaching pedagogical practices. The research results show Adele Oliveira used practical and experimental modern methodological teaching methods in the subjects she taught. Due to this, in her scholar routine, she avoided physical punishment and mechanical teaching and learning strategies

This project goes beyond the interfacial field of cinema, History and education. We take as our object the epistemological potential of the cinema at the educational scenario, specifically the use of films integrated to the practices of History teachers and educative processes in which we have taken part as a builder. Our objective is to map, initially, the knowledge around this use to search a synthesis and its empirical application. From the methodological point of view, we have made use of different perspectives: (a) interviews with the educator subjects; (b) observation of their practices and formative circumstances; (c) filmic analysis and the relation of the cinema s epistemology with the other areas ones (initially History and further Journalism). Our analysis allowed us to portrait the film such as an epistemological-troubling category, what makes the cinema rather a builder technology and not simply a complementary and illustrative technological resource. Therefore, we have realized that the restriction to the cinema s educational function is linked to the restrictions to the theoretical categories to an only interfacial aspect: historical film as a film which portraits the past (at the historical field) and film on journalism as a film which approaches a single object of Journalism (at the journalistic field). These discussions happen, consequently, at the arena of the nature of cinema s genres (fiction and documentary), which are understood in a naïve way, simpler than its epistemological possibilities, boosted at this research when we analyze the confluence between fiction and reality. The reflections on educative practices and in formation related to the cinema had occurred in three empirical realities: research with professors in performance, practices docent s and accompaniment of students of history. Have to do with our personal career as a teacher and researcher and, when analyzed other practices, have become, unavoidably, the subject and object of this project

The purpose of this work is to approach and understand the Social Representations (SR) (MOSCOVICI, 2003) about Physics and Chemistry from people who are major in these courses, as well as their Social Representations about teaching . We took as principle that approaching these representations it would be possible to relate their symbolic contents, in order to show how people who are following the first segments of bachelor degree courses in Physics and Chemistry become teachers, taking into account a psychosocial view. Two source of data was used during this research: Free-association Technique FA (ABRIC, 1994); and Multiple Classification Procedure (MCP) (ROAZZI, 1995). The analytical treatment of the collected data from FA was done according to the proposition of Grize, Vergés and Silem (1987 apud ABRIC, 1994, p. 66). MCP data were analyzed through MSA (Multidimensional Scalogram Analysis) and SSA (Singular Spectrum Analysis) methods associated with the Facet Theory (BILSKY, 2003). The discourses of MCP discussing groups at the moment of explanations were studied by Content Analysis as it was proposed by Bardin (1977) and Franco (2005). Indicative of an approach to the relations with knowledge (CHARLOT, 2000), the connections which aroused from the analyses showed that the group of future majors in Physics thought that this scientific field was based on a rationalist conception, influencing the idealization sense of the phenomena to be explained by Physics. Thus, Physics as school content started to require the student of the fundamental and high school to think abstractly as a cognitive skill of learning. The identifying elements observed in the relations between SR about Physics and Teaching aroused from the antagonism between future majors and their teacher, as well as from the speculation between their fundamental and high school students and themselves, mainly when they had to face the act of teaching due to the obstacles imposed by the own educational system, and by the weakness of the initial preparation. The group of future majors in Chemistry, through its discourses, showed these relations when they conceived empiricist Chemistry and said that teaching was the way of transmission of this knowledge, and didactics of Chemistry teaching was the direction to learning through pedagogic methods in order to lead the students to discoveries. The psychosocial contents which were built and showed from the symbolic relations in the studied SR achieved the relation of identity. This relation revealed identifying elements for these people, resulting from the traffic between their condition as students of Chemistry, and as teachers regarding their work, what placed the current relational contents in the teaching space, named as Knowledge changing and Adaptability . In order to study emerging questions in the discussing environment about formation and teaching professionalization, we focused the psychosocial view on this traffic and managed to observe epistemological practical and pedagogic obstacles that limited a configuration of the teaching work as a professional activity, especially from the particular conditions which led the relations of senses to Physics , Chemistry and Teaching ; and Chemistry and Physics as it was seen in this research. Generally speaking, we noted that these obstacles can denounce such obstacles concerning to the pedagogic doings which mainly impair the learning process of fundamental and high school students

This study focuses on the central Brazilian historiography of science, focusing specifically on the life and work of a contemporaneous mathematician-physicist, and becomes part of the set of research results that investigate, organize and describe personal, intellectual and professional itineraries of Brazilian scientists and educators. The theme chosen for the study ran from seminars on Mathematics in Pará and is up to organize and describe the life history, education, professional experience and scientific production of William Mauricio Souza Marcos de La Penha (Guilherme de La Penha), considering their academic, professional and intellectual life history, so that their academic and intellectual production be spread over the Brazilian scientific and academic community. We adopted the historical research as theoretical and methodological base for the development of this study, rising arguments about the profile of Guilherme de La Penha to characterize him as a multiskill intellectual and to reveal that his thoughts about science, technology, training scientists and educators were in accordance with their writings and their professional practice in order to build a first story about the life and work of William de La Penha. In this sense, we took the theoretical aspects related to historical research, biographies, intellectual itineraries, files and inventories as sources and historical construction vehicles in order to point out the essential elements to form a profile of the transdisciplinary intellectual historians, ie a profile scientist who carries out the research, management and administration, as well as a committed educator to the on-going training and forming process. The results pointed in different directions, among which we highlight the creation of Seção Guilherme de La Penha at Universidade da Amazonia, producing several articles about the life and work of William de La Penha presented at national and international conferences and the proposal for documentary displays which could contribute to understanding the implementation of a scientific area in Pará State, an area that would not only be restricted to the production of knowledge, but more than that, it would include the spreading, which provides various means, primarily through education. Thus it was possible to ensure that La Penha has an intellectual profile that can be considered a multi-and transdisciplinary intellectual who defends the possibility of forming a scientist one and multiple, non-linear attitudes and dialogues with all other areas in order to be understood under a model scientist for the twenty-first century based on the model clearly inspired by the scientist authors with which he identified throughout their training and professional activities, like the three that stood out in their relationship science: Archimedes, Leonhard Euler and Cliford Ambrose Truesdell

We seek, through this study, to analyze about social representation that the students of licentiate degree course of the Federal Institute of Education, Science and Technology of Rio Grande do Norte - IFRN - have about didactic-pedagogical subjects. We utilize the Social Representations Theory (MOSCOVICI, 2009; 2012; JODELET, 2001) as a theoretical and methodological contribution and as aim, we identify this social representation and understand how it is influenced by the formation of these undergraduates. So we developed the research under the seven undergraduate classroom courses offered by IFRN, namely: Biology, Spanish, Physics, Geography, Computer Science, Mathematics and Chemistry, covering units located both in the capital and in the countryside. While methodological approach we used the Procedure of Multiple Classification (PMC) - (ROAZZI, 1995), whose realization requires a set of words achieved through of Free Technique of Words Association - FTWA - (ABRIC, 1998). For this realization we have a total of one hundred twenty (120) participants, with thirty (30) in FTWA and other stage in the realization of free classification and directed that correspond to the MPR. Achieved the empirical data, we use the analysis of content (BARDIN, 2011; FRANCO, 2007) and multidimensional (ROAZZI, 1995) for the course of his interpretation. Finally, we identify the social representation of didactic and pedagogical subjects centered around the idea that it is through these subjects that can achieve the profile of "good professional" as one who gathers knowledge and attributes required for the full development of teaching involving capabilities it and characteristics that mark the sense of professionalism. Furthermore, we found that the anchoring social representation on the understanding that these disciplines "teach the teacher to be" in the image and its objectification of the "good teacher", ie, one that reaches through the training process and experiences, qualities that make it unique and able to carry full professional. Still see that the actions of the teacher trainer affects the way students perceive, assume and engage in the study of teaching and pedagogical subjects and it reflects significantly the social representation then created

This study aims to contribute with the professional development of the Trainers of childhood education teachers of the City Department of Education of Natal/RN, through a formation in context, trying to understand the teaching knowledge required in the practice of these professionals. The focus of the research is in teaching knowledge understood as the ideas, beliefs, conceptions, reasons, arguments, speeches that the trainers builds during his life (ALTET, 2001; PIMENTA, 2002; TARDIF, 2001; 2002). The study inserts itself in the qualitative approach of the educational research and the chosen methodology has characteristics of an inquiryaction. In the process, the following instruments had been used: questionnaires, press conferences, personal documents. The relevance of the present research is in achieving reflections concerning the role of the trainers of teachers, who needs to be seen as a mediator in the formation of teachers, in view of the fact that he interferes and is determinative in such a way in the formative process as in its results. The findings demonstrate that: a) the identity of the trainer is in a development process, what it is resembled to the effective situation of that, symbolically, the trainer exists, however, his attributions still are not enough clear; b) the teaching knowledge of the formation in the childhood education are related, among others points, primordially, to the function / role of the childhood education, child and teacher s point of view of this stage of the basic education; c) the Trainers teaching knowledge, concerning the teaching performance, ratifies the multiplicity of knowledge that the trainer must has, beyond the necessary complementarities and conciliation between the administrative and pedagogical aspects in the exercise of the function; d) the Trainers have knowledge that are according to the speech, consisting as declarative knowledge; e) there is a conflict between the teaching knowledge of the Trainers and the actions that are part of real life, generating contradictions between the formative saying and making

This dissertation aims to contribute on teaching of mathematics for enabling learning connected to the relationship among science, society, culture and cognition. To this end, we propose the involvement of our students with social practices found in history, since. Our intention is to create opportunities for school practices that these mathematical arising from professional practice historical, provide strategies for mathematical thinking and reasoning in the search for solutions to problematizations found today. We believe that the propose of producing Basic Problematization Units, or simply UBPs, in math teacher formation, points to an alternative that allows better utilization of the teaching and learning process of mathematics. The proposal has the aim of primary education to be, really forming the citizen, making it critical and society transformative agent. In this sense, we present some recommendations for exploration and use of these units for teachers to use the material investigated by us, in order to complement their teaching work in mathematics lessons. Our teaching recommendations materialized as a product of exploration on the book, Instrumentos nuevos de geometria muy necessários para medir distancia y alturas sem que interuengan numeros como se demuestra em la practica , written by Andrés de Cespedes, published in Madrid, Spain, in 1606. From these problematizations and the mathematics involved in their solutions, some guidelines for didactic use of the book are presented, so that the teacher can rework such problematizations supported on current issues, and thus use them in the classroom

Atualmente, os conceitos de mundos de letramentos e agência social nos permitem observar o desenvolvimento de competências relacionadas às práticas sociais e às ações transformadoras que influenciam, de forma decisiva, a vida de jovens seminaristas e a vida das comunidades das quais fazem parte. Com este trabalho objetivamos contextualizar social e culturalmente os letramentos na esfera do lar e a influência da família na formação do seminarista bem como evidenciar o papel do grupo de jovens na formação pessoal e o fortalecimento do sentimento de autoestima produzido pela relação de confiança e pela delegação de responsabilidades. Procuramos, por fim, descrever os principais pilares formadores do Seminário, como agência de letramento, e sua importância na formação identitária do seminarista. Trata-se de pesquisa qualitativa de cunho etnográfico cuja metodologia baseia-se em análise de narrativas semiestruturadas e questionários sócio avaliativos. Os fundamentos teóricos que sustentam nossa pesquisa estão ancorados nos estudos de letramento (BARTON, HAMILTON, IVANI, 2000; STREET, 2003; OLIVEIRA, 2010), na Análise do Discurso (FAIRCLOUGH, 2001), no Realismo Crítico (ARCHER, 2000; AHEARN, 2001), na Sociologia (GIDDENS, 2003, 2005); (SZTOMPKA, 2005), no Interacionismo Simbólico (BERGER, P. L., LUCKMANN, 2009). A análise dos dados nos permitiu: 1) (re)afirmar o papel da instituição família como a principal guardiã do conjunto de ideias e valores, os quais fortalecem as representações sociais associadas a essa instituição, sendo responsáveis pela formação identitária de nossos colaboradores; 2) reconhecer o importante papel social desempenhado por instituições sociais informais que, com o objetivo de promover ações evangelizadoras e solidárias, proporcionam aos seus catequizados o desenvolvimento de múltiplas competências direcionadas à agência pessoal e social, dentre as quais destacamos as Pastorais como fortes aliadas nesse processo formador de identidades sociais positivas, porque os indivíduos que delas participam adquirem competências agentivas que são responsáveis por transformações de ordem pessoal e social; 3) descrever os processos formadores que permitem a manutenção da tradição dentro de uma instituição religiosa. Nossos achados apontam para a necessidade de compreendermos a sociedade como constituída e constituinte de muitos e diversos mundos de letramento, os quais estão a serviço de todo aquele que consegue se perceber como ser atuante no mundo

Considering the following conditions: (1) the fluency demands of students in an undergraduate program in Languages and Literatures/English in the Amazon region; (2) the listening and speaking needs of pre-service teachers of English as a Foreign Language (EFL); (3) my continuing education as a professor of EFL and my academic literacy as a teacher-researcher and pre-service-teacher trainer, this study, which is based on Narrative Inquiry, reports on a teacher experience of working didactically with oral genres through podcasting an activity that emerged with the advent of Information and Communication Technology (ICT). Through this process, I engage with some theorists who promote teaching as a process that is driven by a concept of language as social practice. Subsequently, I make use of the notions of context of culture and context of situation, derived from Systemic Functional Linguistics, as well as the concept of genre and register derived from the perspective of this theory. Based on these principles and beliefs, the Amazon region constitutes the register (situation) of the genres used in this study. These principles also provide, opportunities for building learning strategies appropriate to this local context, and also to teach listening and speaking skills from a task-based approach. During the experience, based on the reflective teacher-education model, the participants produced narratives about the process, which I then analyzed according to Ely, Vinz, Downing and Anzul (2001), who propose possibilities of composing meanings in Narrative Inquiry. Based on this perspective, I discuss the following topics, which were highly emphasized in the participants narratives: the lack of didactic activities using oral genres; the relevance of context within teacher education; and collaborative work as a strategy to overcome gaps in digital literacy, language fluency and teaching skills. The meanings I thereby compose point to a paradigm shift in English language teaching within this context. I also argue for a pedagogical practice that is engaged with historical and socio-cultural issues, and with the development of language skills, also one that promotes the implementation of ICTs at the very start of teacher training programs, adopting teaching and learning strategies that correspond to the demands of fluency in this particular context, and deficiencies imposed by geographical isolation

The present work aims the preparation of filmes of strontium-doped lanthanum manganite (perovskita) yttria-stabilized zirconia (LSM-SDC) films deposited on substrate of YSZ by means of spin coating technique having as principal objective their application to solid oxide fuel cells of intermediate temperature. La0,8Sr0,2MnO3 and Ce0,8Sm0,2O1,9 were obtained by modified Pechini method by use of gelatin which act as polymerization agent. The powders obtained were characterized by Xray fluorescence, X ray diffraction, electronic scanning microscopy and the superficial area by BET method. The results obtained by X-ray fluorescence showed that the route adopted for obtention of powders was effective in the obtention of the compositions with close values to the stoichiometrics. Ethyl cellulose was used as pore-forming agent and mixed with the LSM-SDC powders in weight proportions of 1:24, 2:23 and 1:9. The films were sintered at 1150 °C for 4 h and characterized by X-ray diffraction and scanning electron microscopy technique (SEM) and atomic force. The phases quantification of the precursory powders and of the obtained films was carried through Rietveld method. According with the analysis of SEM, as the content of ethyl cellulose was increased, the pore distribution in films become more uniform and the pore size reduced. The methodology used for the obtention of the films was very efficient, considering a material was obtained with characteristics that were proper to the application as electrolyte/cathode system to solid oxide fuel cells

Great part of the gold mineralizations are associated with shearing zones through which circulate a great volume of fluids, that interact with the host rocks, originating leaching or precipitation of chemical elements, including gold. The studied mineralizations are inserted in the Seridó Belt. The tungsten mineralization in Brejuí Mine is hosted in calcsilicate rocks from Jucurutu Formation. The São Francisco auriferous mineralization has as host rocks mica-schists from Seridó Formation, while the Ponta da Serra and Fazenda Simpático mineralizations are hosted in orthogneisses of this fold belt basement. The research conducted on these mineralizations had the purpose of integrate the data of chemical elements behavior during the shearing/mineralizing event, and its influence on the isotopic systems Rb-Sr and Sm-Nd. The studies of chemical mobility in the auriferous mineralizations showed that elements that during the shearing displayed in general an immobile behavior were Al, Ti and Zr. Among the elements that were mobilized during the event, K and Rb showed mass gain in ali belts of transformed rocks, while the elements Ca, Na and Sr normally lost mass. Petrographic studies showed that the minerais biotite and plagioclase, in all investigated mineralizations, played an important role in the chemical reactions occurred in the transformed rocks to the generation of muscovite, cordierite and sillimanite, justifying the input of K to the formation of muscovite, and the release of Na and Ca from plagioclase to the fluid phase. In the São Francisco auriferous mineralization, the results of the Rb-Sr isotopic analysis yielded ages of 645 ± 19 Ma and 596 ± 17 Ma, with both samples, from original and transformed rocks. Two ages, 569 ± 20 Ma. and 554 ± 19 Ma., were obtained with samples frem the transformed rocks domain. These ages suggest that there were two metamorphic pulses during the emplacement of the mineralized shearing zone. The Sm-Nd data yielded TDM ages of 1,31 Ga and 1,26 Ga with 3Nd (0,6 Ga) of -0,26 e -0,40 for the original and final transformed rocks, respectively. In case of the orthogneisses of Caicó Complex, e.g. the Ponta da Serra and Fazenda Simpático mineralizations, the Rb-Sr data did not yield ages with geological significance. In the Ponta da Serra mineralization, the Sm-Nd isotopic data yielded T DM ages of 2,56 Ga and 2,63 Ga to the original rocks and of 2,71 Ga to the mineralized sheared rock, and values of 3Nd (2,0 Ga) between -3,70 e -5,42 to the original and sheared rock, respectively. In the Fazenda Simpático, Sm-Nd data yielded TDM between 2,65 and 2,69 Ga with values of 3Nd (2,0 Ga) between -5,25 e -5,52. Considering the Sm-Nd data, the TDM ages may be admitted as the age of the parental magma extraction, producer of the protoliths of the orthogneisses from Ponta da Serra and Fazenda Simpático mineralizations. The chemical mobility studies showed that in the basement hosted mineralizations, Rb achieved mass while Sr lost mass, as Sm as well as Nd were strongly mobilized. The Sm/Nd ratio remained constant, however, confirming the isochemical character of those elements. In the basement mineralizations, Rb-Sr ages are destituted of geological significance, because of the partial opening of the isotopic system during the tectono-metamorphic transformations. In the tungsten mineralization, the diagram Sm-Nd constructed with the whole-rock data of calcsilicatic and the high-temperature paragenesis (garnet, diopside and iron-pargasitic hornblende) indicated an 631 ± 24 Ma age, while with the whole-rock data and low-temperature paragenesis (vesuvianite, epidote and calcite), a 537 ± 107 Ma age was obtained. These ages, associated with the petrographic observations, suggest that there was a time gap among the hydrothernal events responsible by the formation of the high and low temperature paragenesis in the calcsilicatic rocks mineralized in scheelite
