Item Ações na escola para educação e segurança no trânsito(Universidade Federal de Goiás, 2021) Santos (org.), Alex Mota dosItem Análise do tema economia solidária nas produções dos programas de pós-graduação em Geografia(2015-07) Severino, Maico Roris; Barbosa, Janete Costa Ribeiro; Ribeiro, Marina PiresThe Solidarity Economy experiences have grown exponentially in Brazil since the start of the 21st century. To that extent, the various areas of knowledge have been developing studies to better understand this phenomenon, among them, Geography. The purpose of this paper is, therefore, to perform a quantitative and qualitative analysis of graduate programs productions (theses and dissertations) on geography and the solidarity economy topic. Hence, a literature review was conducted in order to gather all theses and dissertations up to the year of 2014, that addressed the topic. It was perceived that the geography research on the topic is still limited and regionally concentrated, but on the other hand, the studies analyzed show interesting analysis and broad scopes. The main contribution of this paper is the diagnosis of how the solidarity economy theme has been studied in geography, as well as to point out other research opportunities.Item Avaliação do ganho ambiental com o uso da bicicleta de carga na última milha - uma revisão sistemática da literatura(Universidade Federal de Goiás, 2023-09-22) Oliveira, Fernando Soares Ribeiro de; Guerrero, Cintia Isabel de Campos Roque; Andrade, Carlos Eduardo Sanches de; Andrade, Carlos Eduardo Sanches de; Souza, Alessandro de Santana Moreira deThe continuous growth of cities entails the demand for the use of means of transport, both for passengers and cargo. In the last mile, conventional means of transport are used, which consume fossil fuels, but more and more people are looking for other transport alternatives that live better with the environment. An example is the transport by bicycles and cargo tricycles, which can be used as sustainable alternatives for transporting cargo in the last mile. This work aimed to apply a Systematic Literature Review on using these vehicles in the last mile to evaluate the environmental gain obtained. The PRISMA methodology was used, and it led to quantitative and qualitative results relevant to the theme. Ten published articles were selected, seeking to obtain the state of the art of these sustainable transport alternatives worldwide. The results showed that the use of bicycles and tricycles is successfully applied to small and medium-sized goods, food products, pharmaceuticals, and documents, among others, and has significantly contributed to the reduction of congestion, CO2, traffic accidents, and local pollutants, increasing the quality of life in cities. An analysis of the results and its application in Brazil was carried out, where the potential for use was found, but in need of improvements in cycle paths and implementation of pilot projects.Item Correlações entre transporte e desenvolvimento econômico aplicadas ao turismo: uma análise a partir do município de Caldas Novas/Go - Brasil(2017-12) Perim, Thiago Marcell Pires; Caetano, Mauro; Costa, Sérgio Henrique Barroca; Pimenta, Daiana Paula; Almeida, Cristiano FariasUnderstanding the elements that potentiate the economic development of a certain locality becomes necessary in the managerial sciences and planning of touristic destinations. Collaborating with theoretical gaps related to the particular analysis of transport activities and their impact on tourism, this study seeks to identify the economic relations between tourism and road transportation of people in tourist cities, being adopted as a reference the case of Caldas Novas / Goiás / Brazil, one of the main tourist destinations in the country. From the use of economic data and the characteristic of people transportation, statistical models has been used to analyze, for example, the impact of the increase of vehicles to public transport at the gross domestic product of the municipality, demonstrating the levels of impact between the variables considered. Such results can be used to manage the transport activities and for the planning of tourism.Item Exploring the relationship between transportation infrastructure and regional economic growth using Losch’s location theory(2021-05-14) Almeida, Cristiano Farias; Silva, Francisco Gildemir Ferreira da; Araujo, Paulo Henrique CirinoThere are some knowledge gaps regarding the relationship between transportation infrastructure and economic development, especially about economic impacts that occur due to implementation of infrastructure in a given region, albeit various studies have addressed the issue. This paper aims to identify variables that affect economic development in order to contribute to the development of a theoretical model that could explain the relationship between transportation infrastructure and economic development. The theoretical model is satisfactory because it begins by analyzing the actions generated by the transportation infrastructure. Moreover, the model is based on the Location Theory considering the economic development and taking into account variables such as transportation costs, gain, product value, consumption, competition between companies and lastly monopoly. Finally, an econometric procedure, Spatial Panel Auto Regressive Vector Model (PVAR), was used to evaluate the relationship between economic development and investments in transportation infrastructure.Item Guidelines to devise a multimodal freight transportation network in developing regions under economic growth approach(2014-12) Almeida, Cristiano Farias; Gularte, Juliana Gomes; Yamashita, YaekoIn Brazil, especially at the Amazon Region, the relationship between transport and economic development has been studied since 70s with elaboration of several plans. However, due to many factors, such as the incompatibility between the proposed models of transport planning and territorial planning, the expected results were not reached. Under these aspects, the goal of this paper is to define guidelines in order to devise a multimodal freight transportation network that allows efficient transport of products in a developing region. This network was developed using natural resources and it stimulates the economic growth and development based on the Growth and Development Poles Theory and Graphs Theory. As result three networks related to three different scenarios – status quo, investment in transport infrastructure by the governmental programs, and the strategy scenario – have been elaborated and analyzed considering the operational transport costs and their spatial configuration.Item Identification of development poles on Brazilian Amazon region and analysis of the geographic accessibility(2020-10) Santos, Alex Mota dos; Almeida, Cristiano Farias; Soares, Daniel de Oliveira; Silva, Carlos Fabricio Assunção daIdentification of development poles within the regional planning is important for defining the nodes of a given transport network and plays the role of driving economic growth in a region. Nevertheless, such proceedings are complex, especially in some areas where there is a lack of data that could support studies of this nature, for example in the case of the Amazon region. Thus, this study aims to identify development poles using spatial analysis of production values of soya, coffee, wood, and mineral products like cassiterite, aluminum ore, iron ore and copper. In addition, the geographic accessibility analysis was carried out at these poles in order to identify the potential of the transport network to be structured. Results demonstrated that it is possible to build a dense transport network by identifying more development poles, which would increase the connectivity, allowing more intense exchange of flows and development of the region.Item Isótopos estáveis (C, O, S) e geoquímica de rocha total de carbonatitos da província Ígnea Alto Paranaíba – SE Brasil(2016-09) Gomide, Caroline Siqueira; Brod, José Affonso; Vieira, Lucieth Cruz; Junqueira-Brod, Tereza Cristina; Petrinovic, Ivan Alejandro; Santos, Roberto Ventura; Barbosa, Elisa Soares Rocha; Mancini, Luis HenriqueThe present work investigates the relationship between whole-rock geochemistry and stable isotope composition from carbonatites belonging to the Tapira, Araxá, Salitre, Serra Negra, Catalão I, and Catalão II alkaline-carbonatite complexes of the Alto Paranaiba Igneous Province (APIP), central Brazil and from the Jacupiranga Complex, of the Ponta Grossa Province, southeast Brazil. The APIP complexes are ultrapotassic, comprising bebedourites, phoscorites, nelsonites, and carbonatites, whereas Jacupiranga is a sodic complex composed of ijolite-series rocks, syenites, carbonatites, and alkaline gabbros. The geochemistry data allied to mineralogical constraints allowed us to classify the carbonatites into five groups, and to devise a chemical index (BaO/(BaO+SrO)) to gauge the magmatic evolution of the studied carbonatites.The APIP carbonatites evolve from apatite-rich calciocarbonatites toward Ba-, Sr-, and rare earth element (REE)-rich magnesiocarbonatites. This evolution is mostly driven by apatite, phlogopite, dolomite, and calcite fractionation and consequent enrichment in monazite, norsethite, and strontianite. Stable isotope data show a wide diversity of petrogenetic processes in play at the APIP, relatively to the Jacupiranga Complex, which is interpreted as a result of the shallower intrusion levels of the APIP complexes. Such shallower emplacement, at low lithostatic pressure, allowed for a complex interplay of fractional crystallization, liquid immiscibility, degassing, and interaction with hydrothermal and carbohydrothermal systems.Item Mapeamento geológico da região das nascentes do Rio Vermelho e arredores no município de Goiás (GO) em escala 1:20.000(Universidade Federal de Goiás, 2023-08-29) Gomes, Camila de Sousa; Altoé, Elisandro Seraco; Macedo, Sarah Karoline Costa; Rodrigues, Sérgio Wilians de Oliveira; Rodrigues, Sérgio Wilians de Oliveira; Lima, Martha Noélia; Carneiro, Jônatas de Sales MacedoThe present work consists of a detailed geological mapping study in the region of the headwaters of the Vermelho River and adjacent areas in the municipality of Goiás (GO), carried out at a scale of 1:20,000. The main objective of the study was to analyze and describe the geological characteristics of the region, aiming to understand its geological and structural evolution. The adopted methodology involved fieldwork, analysis of collected data, such as direct observations of rocks and geological structures, as well as the collection of samples for petrographic and geochemical analysis. Additionally, geophysical data and topographical survey information were used to assist in the interpretation of geological features. Fourteen lithological units and alluvial cover were identified. These units were placed in the context of existing literature. Petrographic analyses allowed the characterization of rocks in terms of mineralogy and texture, contributing to the interpretation of formation and metamorphic conditions. Geochemical analyses aided in understanding the chemical characteristics of the rocks, providing insights into the provenance of the rocks and associated geological processes. This geological mapping study provides important insights into the geology of the study area, such as the relationships between the mafic-ultramafic rocks of the Goiás Velho Group and the Caiçara Complex, and between these rocks and the Serra Dourada Group. The findings are relevant not only for understanding the local geological evolution but also for comprehending geological phenomena in broader contexts. Furthermore, the mapping serves as instrumental material for Ediminas Mineração Ltda, providing support in the context of their mineral exploration activities.Item Mapeamento geológico integrado 1:50.000 da região da Serra da Jiboia (GO) - área 1(Universidade Federal de Goiás, 2023-02-15) Coutinho, Nathália Amaral; Maciel, Victor Augusto Silva; Nascimento, Estela Leal Chagas do; Lopes, Débora Nogueira; Lopes, Débora Nogueira; Santos, Marcelo Henrique Leão; Siepierski, LincolnThis paper presents the results obtained from the 1:50000 mapping of the Serra da Jiboia region. The detailing of the geological units was possible with the conciliation of bibliographical survey, photointerpretation, geophysical, geochemical, and geoenvironmental, lithological and structural data obtained in the field. As a result, the following mapped units were detailed in the context of the Brasília Belt brim and the Goiás Magmatic Arc (AMG): Anicuns-Itaberaí Metavolcanosedimentary Sequence (SAI), Campestre Gnaissic-Migmatitic Complex, Santa Bárbara Complex and the Creoulos Granodiorite. The SAI is characterized in forearc basin associated with an island arc system, recorded by platform sedimentation in the rhythmic-carbonate unit and marine regression depositional in the psamo-pelitic unit. The Creoulos granodiorite records syncolonal magmatism of meta to peraluminous granites. The geological evolution is marked in the Brasiliano, responsible for the opening of the Goiás Ocean and later the closure. This phase concludes the formation of island arcs and the Brasília orogen. The deformation of the rocks is represented by east-west compression that resulted in isoclinal thrust folds with N-S axis and eastward vergence with higher temperature and pressures. Conjugate fracture systems occur, with E-W and NE-SW direction that, by progressive deformation, originate NS, NW and NE transcurrent shear zones. The observed metamorphism of the rocks is a variation of high greenish schist to amphibolite facies, associated to SAI, besides hydrothermal metamorphism linked to shear zones. The area presents some economic aspects, with potential for manganese, calcitic marble and remineralizers for agriculture and gravel and sand for civil construction.Item Mapeamento geológico integrado 1:50.000 da região da Serra da Jiboia (GO) - área 2(Universidade Federal de Goiás, 2023-02-16) Nadote, Hianna Carvalho; Cardoso, Sara Vieira; Lopes, Débora Nogueira; Nascimento, Estela Leal Chagas do; Nascimento, Estela Leal Chagas do; Paixão, Marco Antônio Pires; Chagas, Daniel Bezerra dasThis work begins through the processing and interpretation of image data, geophysical, geochemical, mineral resources and environmental data and following data collect of lithological, structural, environmental and mineral occurrence in field. The geological mapping in the Serra da Jiboia (GO) region intend to describe and interpretate the units Anicuns-Itaberaí Sequence, Gnaíssico-Migmatítico Complex and Santa Bárbara Body. The first fase of deformation is associated to the S1 foliation, to the intrafolial folds and quartz veins, the phase 2 is characterized for the shale which is well preserved in all area and associate with the assimetric isoclinal regional fold of the Serra da Jiboia. The third phase also receive emphasis by the extensive shear zone which occurs in the Santa Bárbara Body limits, this compressive deformational fase also occurs crossing folds. The fase 4 distinguishes for the crenulations and spaced cleavage. The potential economy of the area is diverse and with emphasis on clay and gravel occurrences.Item Mapeamento geológico integrado 1:50.000 da região da Serra da Jiboia (GO) - área 3(Universidade Federal de Goiás, 2023-02-14) Silva, Gabriela Soares Freitas e; Silva, Michele Urbano da; Reis, Mateus Andrade; Reis, Mateus Andrade; Heringer, Rodrigo de Almeida; Lima, Martha NoéliaThe area of study is located in the southeast portion of the state of Goiás, next to the municipalities of Nazário and Anicuns. It is geologically located in the context of the Goiás Magmatic Arc (AMG), which is composed by rocks that register the complex metamorphic and structural geotectonic development, associated with the Brasiliano orogenesis (Arquean-Neoproterozoic), developed mainly during the structuring of the Brasília Belt. The integrated geological mapping aimed to map the different lithofacies associated with the outcropping units, namely: Anicuns Itaberaí Metavolcanosedimentary Sequence, Anápolis Itauçu Granulitic Complex, Campestre Gneiss Migmatitic Complex, Anicuns-Santa Bárbara Suite, Creole Granite and undifferentiated granitic intrusions. The work was carried out from the processing and interpretation of photointerpretive, geophysical, geochemical and geoenvironmental data, as well as lithological and structural data collected in the fieldwork, generating geological, structural and point maps as final products. The rocks exhibit metamorphism from greenschist facies to the amphibolite-granulite transition. Four deformational phases were identified: D1 generated a main E-W compression, marked by isoclinal folds with NS axes, which folded S0 and originated the S1 foliation; D2 represents the continuity of compression, generating parasitic folds and S2 foliation; D3 represents the formation of NW-SE shear zones and thrust faults, associated with the continuity of E-W compression; D4 reflects the decrease in compression, generating S3 foliation. The area presents occurrences of minerals used in civil engineering and industry.Item Mapeamento geológico integrado 1:50.000 da região da Serra da Jiboia (GO) - área 4(Universidade Federal de Goiás, 2023-02-15) Santos, Daniel Carelli Batista; Carvalho, Franklin Williams Silva de; Lima, Gabriel Dutra de; Temporim, Filipe Altoé; Temporim, Filipe Altoé; Oliveira, Ítalo Lopes de; Arab, Paola BrunoThe present work had as objective the geological mapping in the region of Nazário - GO from the accomplishment of systematic works that integrated data from remote sensing (orbital images), geophysical, geochemical, lithological, petrographic, structural and geoenvironmental surveys. The result of the integrated work was the geological cartography of Neoproterozoic units associated to the Goiás Magmatic Arc: Metavolcanosedimentary Anicuns-Itaberaí Sequence, Anápolis-Itauçu Complex, Creoulos Granite and Santa Bárbara Anorthositic Complex. Four deformational stages were recognized in the area: D1 represents E-W compression associated with regional folds with eastward vergence; D2 is the E-W compression refolding of the D1 progression; D3 characterizes shallower crustal level change during deformation progression and generates N-S lateral shortening of the D2 deformation and N-S axis crenulations; D4 represents the ruptile-ductile stage of E-W compression with formation of shear zones and thrust faults. In general, the rocks of the Anicuns-Itaberaí Metavolcanosedimentary Sequence in the study area are metamorphosed between green schist and amphibolite facies with retrometamorphism to green schist facies. The region is relevant for understanding the evolution of the Brasília Belt, as the rocks are linked to tectonic and magmatic events that started with in the formation of the Magmatic Arco f Goias. The study area is economically interesting due to the presence of mineral occurrences with potential for metallurgy (manganese and iron) and civil construction (sand, gravel, crushed stone and ornamental rocks).Item Mapeamento geológico-ambiental, em escala 1:25.000, de área adjacente ao reservatório do ribeirão João Leite, região metropolitana de Goiânia - Goiás(Universidade Federal de Goiás, 2022-10-08) Álvares, Amanda Pereira; Silva, Ariele Lisita; Silva, Icaro Souza; Canile, Fernanda Maciel; Canile, Fernanda Maciel; Nogueira Neto, José de Araújo; Trindade Netto, Gil BarretoThe area under study comprises a peri-urban strip, located in the northwest region of the municipality of Goiânia, capital of the state of Goiás, which is part of the rural macro-zone of João Leite, an area destined for the preservation and sustainable use of its resources, under the influence of the Área de Preservação Permanente de João Leite (APAJoL). It is inserted in the geological context of the Anápolis-Itauçu Complex, belonging to the Brasília Belt, formed during the Brasiliana Orogeny in the Neoproterozoic. The objective of this work was to carry out an integrated mapping, in which the main aspects of the physical environment are related to geoenvironmental characteristics, based on the analysis of variables such as hypsometry, slope, drainage density, soil use and occupation, erosive susceptibilit, structural surveys, among others. Furthermore, in the area, four lithotypes belonging to the Anápolis-Itauçu Complex were characterized: i) garnet-hornblende-clinopyroxene-plagioclase granulite; ii) hypersthene gneiss, with presence of hornblende; iii) tremolithites, indicative of metasomatism; vi) quartzite metasedimentary sequence. The results obtained suggest that it is necessary to adopt inspection measures and control the advance of areas for agricultural purposes, implementation of allotments and residential condominiums that increase the deforestation of the Cerrado and cause erosion that cause silting and pollution of the rivers that supply the city.Item Mapeamento geológico-geotécnico: mina de Barro Alto - GO, Anglo American(Universidade Federal de Goiás, 2022-10-14) Santos, Lavoisier Matias dos; Arab, Paola Bruno; Rodrigues, Sérgio Wilians de Oliveira; Rodrigues, Sérgio Wilians de Oliveira; Temporim, Filipe Altoé; Lima, Martha NoéliaThe Barro Alto Mafic-Ultramafic Complex is part of the Goiás Massif, which is inserted in the geological context of the Tocantins Province. The deformations associated to the amalgamation of Gondwana generated in the study area a series of structures and deformation stages. A schistose (S1) subparallel to the compositional banding (S0) is characterized. Boomerang-like refolding patterns associated with flexural slip mechanisms are also observed. Conjunctively, a NE-SW and NW-SE fracture system compatible with idealized fracturing models associated with cylindrical flexural folding are observed. The Barro Alto supergene nickel deposit is composed of lithological units derived from ultrabasic rocks - dunite-serpentinized, dunite boulder, base ore, acid ore, ferruginous ore, internal waste rock, soft chalcedony, hard chalcedony and laterite soil. Nickel extraction in Barro Alto is characterized by open pit mining, which consists of excavation of the soil or soft rock and consequent modification of the topography. These modifications must be technically planned, in order to optimize resources and increase safety levels. Saprolitized heterogeneous massifs are composed of reliquary structural features, rock blocks immersed in the weathered profile (bedrock), and irregular zones with contrasting weathering. These heterogeneities usually control the failure mechanisms and locations, as well as the factor of safety. For this work, in addition to good internal practices, the geological-geotechnical characterization was carried out based on the recommendations suggested by the ISRM and the criteria established by the RMR rock mass classification system (Bieniawski, 1989). The geological-geotechnical characterization indicated a rather heterogeneous and anisotropic massif. Furthermore, the simple kinematic analysis performed as a preliminary study obtained indices higher than 0.1 (10%) for planar and wedge type ruptures.Item Methodology focused on identifying variables necessary to develop logistics clusters(2021-04-29) Almeida, Cristiano Farias; Yamashita, Yaeko; Cools, Mario; Marchal, Jean; Piette, BernardItem Metodologia para avaliação de rotas cicloviárias sob o enfoque da psicologia ambiental(2021-12) Almeida, Cristiano Farias; Hamer, Luciana Joyce; Cools, MarioThis study aimed to develop a methodology for evaluation of cycle routes through indicators and based on Environmental Psychology and the physical characteristics of the urban space. For the study of the people behavior in the urban environment, the legibility and apprehension parameters of the "place" were adopted in addition to the foundations presented by Environmental Psychology: personal space, territoriality, privacy and density/crowding in its relation with cycling. The variables presented were measured through the Hierarchical Analysis in order to evaluate the Via Condition Index, which enabled the definition of a more efficient segment in a road network1 to compose the cycling system. The methodology is composed of the following steps: area delimitation, characterization of the area of study, identification of the segments with greater potential for trips with bicycles, evaluation of the condition index of the route, analysis of intervention opportunities and choice of the stretch of implementation. A case study was carried out in the city of Goiânia in order to validate the presented methodology. Thus, it is intended to assist managers and professionals in decision making regarding the implementation of cycle routes within a behavioral perspective.Item Modelo de acidente de aeronaves por colisão com aves na aviação comercial(Universidade Federal de Goiás, 2023-09-22) Azevedo, Bruna Borges; Bandeira, Michelle Carvalho Galvão da Silva Pinto; Bandeira, Michelle Carvalho Galvão da Silva Pinto; Roriz Junior, Marcos Paulino; Pereira, Leonardo MariniOne of the types of occurrences that have been a problem since the beginning for aviation is bird strikes, which can generate from minor incidents to significant accidents, especially in terms of operating costs for airlines. It is observed in the literature and in the database of official entities, that the occurrence of accidents and incidents increase with the flight movement and aircraft fleet. This shows that studies in this area should be prioritized and bring more assertive responses. Thereby knowledge about what the main factors, how they relate to each other and what most impact this type of accident, collaborates with the operational safety of air transport. In this context, this work aims to present a bird strike accident model for commercial aviation that is able to quantify the impact of the main factors (time, cloud cover, species behavior, species mass, phase of flight, AGL height, affected part of the aircraft), the interrelation of these factors and their probabilities. Thus, a survey of the main factors and occurrences in Brazil between 2011 and 2021 was conducted. From the analysis, the "Bird Strike Accident Model" was proposed, developed using the Bayesian Networks method. Through graphic representation of the model, the impact of the global - among the states that make up the selected factors - was determined in scenarios with and without evidence. Comparing the scenarios with evidence and without evidence of the event, it was identified that the critical scenario in Brazil involves the following factors: fuselage as the main part reached (1º); landing phase as the most critical (2º); aircraft speed up to 80 knots (3º); engine as second main part reached (4º); height AGL up to 500 feet (5º); radome as third main part reached (6º); one bird (7º), mass up to 1,500 grams (8º); night time (9º), clear sky (10º). These results are relevant to the players involved and can contribute to the decision-making process of risk management and operational costs management of airport operators, companies, public and private entities that are related to accident investigations, regulation of civil aviation, training centers, among others.Item New service development process applied on air transport industry(2020-06) Cualheta, Luciana Padovez; Caetano, Mauro; Almeida, Cristiano FariasObjetivo do estudo: O objetivo desse estudo consiste em identificar as principais atividades do processo de desenvolvimento de novos serviços (PDNS) aplicáveis às empresas de transporte aéreo; Metodologia / abordagem: Várias atividades do PDNS foram identificadas na literatura, sendo elaborado um modelo conceitual, cujas atividades foram confrontadas com a realidade a partir de estudos de casos múltiplos realizados; Originalidade / relevância: A indústria de serviços de transporte aéreo é altamente relevante para a economia global e cresceu cerca de 6 vezes mais que o PIB global nos últimos anos. Apesar disso, nota-se que limitações gerenciais na oferta de novos serviços tem sido identificadas no setor; Principais resultados: A partir do desenvolvimento de um modelo conceitual aprimorado a partir de casos práticos, os resultados propoem um modelo de processo de desenvolvimento de novos serviços aplicáveis ao transporte aéreo; Contribuições teóricas / metodológicas: Ao se comparar os resultados dos estudos de caso com aqueles identificados na literatura, há atividades consideradas recorrentes na indústria de transporte aéreo, tais como a análise do ambiente externo e da capacidade financeira da empresa, bem como novas atividades do modelo, como mensuração da participação de mercado e identificação de novos consumidores; Contribuições sociais / gerenciais: Busca-se colaborar com o desenvolvimento de novos serviços que possam ser úteis não apenas na gestão da inovação das empresas, mas também que otimizem a eficiência no setor;Item Recycling process and proto-kimberlite melt metasomatism in the lithosphere-asthenosphere boundary beneath the Amazonian Craton recorded by garnet xenocrysts and mantle xenoliths from the Carolina kimberlite(2022) Gervasoni, Fernanda; Jalowitzki, Tiago; Rocha, Marcelo Peres; Weska, Ricardo Kalikowski; Novais-Rodrigues, Eduardo; Rodrigues, Rodrigo Antonio de Freitas; Bussweiler, Yannick; Barbosa, Elisa Soares Rocha; Berndt, Jasper; Dantas, Elton Luiz; Souza, Valmir da Silva; Klemme, StephanHere we present new data on the major and trace element compositions of silicate and oxide minerals from mantle xenoliths brought to the surface by the Carolina kimberlite, Pimenta Bueno Kimberlitic Field, which is located on the southwestern border of the Amazonian Craton. We also present Sr-Nd isotopic data of garnet xenocrysts and whole-rocks from the Carolina kimberlite. Mantle xenoliths are mainly clinopyroxenites and garnetites. Some of the clinopyroxenites were classified as GPP–PP–PKP (garnet-phlogopite peridotite, phlogopite-peridotite, phlogopite-K-richterite peridotite) suites, and two clinopyroxenites (eclogites) and two garnetites are relicts of an ancient subducted slab. Temperature and pressure estimates yield 855–1102 C and 3.6–7.0 GPa, respectively. Clinopyroxenes are enriched in light rare earth elements (LREE) (LaN/YbN = 5–62; CeN/SmN = 1–3; where N = primitive mantle normalized values), they have high Ca/Al ratios (10–410), low to medium Ti/Eu ratios (742–2840), and low Zr/Hf ratios (13–26), which suggest they were formed by metasomatic reactions with CO2-rich silicate melts. Phlogopite with high TiO2 (>2.0 wt.%), Al2O3 (>12.0 wt.%), and FeOt (5.0–13.0 wt.%) resemble those found in the groundmass of kimberlites, lamproites and lamprophyres. Conversely, phlogopite with low TiO2 (<1.0 wt.%) and lower Al2O3 (<12.0 wt.%) are similar to those present in GPP-PP-PKP, and in MARID (mica-amphibole-rutile-ilmenite-diopside) and PIC (phlogopite-ilmenite-clinopyorxene) xenoliths. The GPP-PP-PKP suite of xenoliths, together with the clinopyroxene and phlogopite major and trace element signatures suggests that an intense proto-kimberlite melt metasomatism occurred in the deep cratonic lithosphere beneath the Amazonian Craton. The Sr-Nd isotopic ratios of pyrope xenocrysts (G3, G9 and G11) from the Carolina kimberlite are characterized by high 143Nd/144Nd (0.51287–0.51371) and eNd (+4.55 to +20.85) accompanied with enriched 87Sr/86Sr (0.70405–0.71098). These results suggest interaction with a proto-kimberlite melt compositionally similar with worldwide kimberlites. Based on Sr-Nd whole-rock compositions, the Carolina kimberlite has affinity with Group 1 kimberlites. The Sm-Nd isochron age calculated with selected eclogitic garnets yielded an age of 291.9 ± 5.4 Ma (2 r), which represents the cooling age after the proto-kimberlite melt metasomatism. Therefore, we propose that the lithospheric mantle beneath the Amazonian Craton records the Paleozoic subduction with the attachment of an eclogitic slab into the cratonic mantle (garnetites and eclogites); with a later metasomatic event caused by proto-kimberlite melts shortly before the Carolina kimberlite erupted.
