Análise faciológica e estratigráfica das formações Taciba (parte superior) e Rio Bonito (membro Triunfo) em poços testemunhados da área de Monte Alegre (PR)

The Triunfo Member, from Rio Bonito Formation, is a potential reservoir for hydrocarbons and water, and contains coal deposits in the northern state of Paraná. On the eastern edge of the Paraná Basin, the Triunfo Member has two depocenters in Santa Catarina and offlap to the North of Paraná; here in two adjacent areas characterized his final lapout. These areas have a number of wells core/logged with the initials MA and NF, Monte Alegre and Figueira North, which were drilled by the Companhia de Pesquisa e Recursos Minerais (CPRM), in order to research for coal in the Rio Bonito Formation. In this study, three wells in the MA area, and they were MA-4, MA-6 and MA-7 was subjected to vertical facies analysis (1D), from the description of wells and processing of data, so that later it was possible to chronocorrelate thereof, together with MA-5 well, through cycles facies (2D). This is a thesis which has never been developed in these wells mentioned above, it was possible to observe the development of part of the Member Taciba (top) and the Member Triunfo as a whole, can be determined three cycles facies to the latter, as well as their depositional environments. Finally, the chronocorrelate showed that there is a tabular architecture between the wells studied, this occurred because of subsidence uniform

Modelo estrutural do maciço rochoso do Depósito de Cobre e Ouro da Mina da Chapada, Alto Horizonte, GO

The Cu-Au mine of Chapada is located in the municipality of Alto Horizonte, in the northwestern portion of Goiás state and is inserted in the geological context of the Brasilia Belt, specifically the Mara Rosa Magmatic Arc, which hosts important deposits of Au and Cu-Au. The rocks found in the study area belong mainly to the Volcano-Sedimentary Sequence of Mara Rosa and are composed of basic to acidic metavolcanic rocks, psammiticpellitic metasedimentary rocks, chemical rocks and also hydrothermal products. Late intrusions occur and are represented by pegmatitic dikes and tonalitic bodies. The ore deposit of the Chapada mine is formed predominantly by the chalcopyrite-pyritemagnetite association, where pyrite is the most abundant mineral. Through the structural mapping of the mining fronts, it was able to recognize three deformational phases (Dn, Dn +1, Dn +2). During the Dn phase, isoclinal recumbent folds were formed, in association with amphibolites facies metamorphism. Later, in phase Dn +1, there was formation of drag folds and intrafolial folds in association with retrograde metamorphism in the greenschist facies. The deformational phase Dn +2, in its turn, was responsible for late symmetrical folding of the foliation, with NS and EW axes, resulting in an interference pattern of the dome-and-basin type

Produção de enzimas xilanolíticas por fungo filamentoso em diferentes fontes de carbono

O trabalho teve como objetivo principal identificar a produção de enzimas xilanolíticas de um fungo encontrado no solo amazônico a partir do seu crescimento em diferentes fontes de carbono e em dois tipos de meio de cultivo: meio semi sólido e meio líquido Vogel. No mei semi sólido o crescimento do fungo aconteceu durante 7 dias, já no meio líquido foi feito em quatro tempos diferentes: 24, 36, 48 e 52 horas. As fontes de carbono usadas para ambos os meios foram: Após o crescimento os meios foram filtrados e foram realizadas a dosagem de proteína pelo método de Lowry e a determinação da atividade específica. Os filtrados foram concentrados através de tratamento com caulin, diálise e precipitação com acetona. Com os filtrados selecionados pode-se determinar o pH e a temperatura ótimas para a xilanase através de curvas de pH e temperatura. O fungo estudado produz enzimas do complexo xilanolítico, sendo que os melhores resultados foram encontrados usando a xilana no meio líquido e o sabugo de milho no meio semi sólido. Para a enzima encontrada o pH de atividade ótima é no valor 5,0 e foram encontrados dois picos de temperaturas ótima, na faixa de 30ºC e 60ºC, o que pode indicar a presença de mais de uma enzima do complexo xilanolítico

Caracterização litogeoquímica dos basaltos do município de Monções -SP

The paper deals with the petrographic and geochemical investigation of basalt flows present in a gravel quarry in the town of Monções in northwestern São Paulo State, members of the Serra Geral Formation of the Paraná Basin. Were collected 11 samples from different horizons within a topographic vertical profile with an average of 18 meters in height. The samples were subjected to macroscopic and microscopic petrographic and chemical major, minor and trace. The results indicated that it is tholeiitic basalts with dense fine grained average. Petrographic analyzes show that basalts studied are basically constituted by plagioclase (between 33 and 49%), labradorite and clinopyroxenes (between 29 and 46%) represented by the subordinate pigeonite and augite, having as accessories opaque (between 3 and 15% ), olivine (<2%), apatite and zircon as dashes. The secondary minerals correspond to cloropheite, chlorite, serpentine, epidote, albite and iron oxides and hydroxy as well as bowlingit of clay, nontronite, and celadonite. The basalts are kind of high-titanium (Hti)> 1.8% TiO2, and apparently belong to the Pitanga magma-type. The geochemical analyzes proved unsatisfactory for the determination of a probable lithogeochemistry differentiation within the vertical stroke for generating multiple data correlation or no immediately discernible trends

Caracterização metamórfica do Greenstone Belt de Guarinos - GO

The study area comprises Guarinos Greenstone Belt which is located in the centralwest state of Goias and has an approximate size of 280 km2. The present work has as main objective to characterize the metamorphism of the greenstone belt and the relationship between the tectonic events and the metamorphism. For the execution of the work we used data collected in the course Geological Mapping of Crystalline Area of the geology course of UNESP, classes 2009 and 2010, the data collected by Alex Choupina Joaquim Andrade Silva in his master's thesis and the information collected in field in the study area. This compilation of data allows approximately 200 thin sections have been evaluated and allowed the construction of the metamorphic map in scale 1:125.000, also allowed the preparation of the geological map in scale 1:125.000 greestone belt, based on 1:25.000 scale maps performed by students of UNESP and the mapping conducted by Silva (2011). The study area was divided into two tectonic compartments depending on the Shear Zone Engenho Velho that longitudinally crosses study area, with direction approximately NW-SE. The west compartment is bordered by granite-gneiss complex and the east compartment, seems thicker to the south and narrows gradually towards the north and its structure is seen in general as a great monoclinal with NW-SE direction with trim to SW, this way your stack was considered as a package of rocks at the base and metaultramafic metamafic the top, with a second package in tectonic contact, which is composed of detrital and chemical metasedimentary rocks. The east compartment is represented by the intrusion of a large granitic body surrounded by amphibolites and metasediments, is bounded on the east by a granite-gneiss complexes through thrust fault, and is bounded on the west by the other compartment. The structure of the compartment is seen as a major axis oriented roughly... (Completo abstract click electronic access below)

Análise do conforto térmico da cidade de Mirandópolis/SP em seus espaços abertos

Mirandópolis/SP appeared in 1934 from the railroad “the Brazil Northwest”, that there it served one of the points of its stretch that had as main function to drain the agricultural production northwestern native of São Paulo of that time. The installation of the town happened absent of concerns with initial urbanístico planning, thus modifying its natural landscape and modifying characteristic ambient without compensatory measures aiming at a future expansion of the urban mesh. Fact this that still causes today consequences the quality of life of the people and also the observed thermal comfort later. Ahead of this, the present work had for objective to identify through measurements of temperature and relative humidity of the city of Mirandópolis/SP the differences that in the fabric urban they corroborate for a comfort situation or thermal discomfort to the outdoors in accordance with the Diagram Bioclimático de Olgyay the collection of data was made throughout the month of July of 2011 involving the attainment of information of Temperature and relative humidity of air and questionnaire applied to the passer-bys in the act of the measurements. Also approaching the different thermal dynamic of the zones of housing in relation to the Urban Cannyon that develops the commerce as predominant activity. This research sample that, although a city to be small, the quality of life of its inhabitants is not only guaranteed by the transport or that its thermal comfort reveals inside homogeneous of the urban perimeter, but that it has yes heterogeneidade in the scope of the urban climate in these spaces

Impactos e características nos projetos hidrelétricos Sul-americanos: o caso de Inambari no Peru, o investimento brasileiro e a lei de consulta prévia, 2006-2011

Esta pesquisa trata de um grande projeto hidrelétrico, Inambari, que estava se transformando em realidade como parte de acordos entre o governo do Brasil no segúndo período de Lula (2006-2010) e do governo peruano de Alan Garcia – AG (2006-2011). Inambari é um dos mais recentes projetos hidrelétricos peruanos feitos para exportar ao Brasil. Mas, apesar de formar parte de um acordo entre esses países, por agora está detido devido a protestos e mobilizações da população dos territ´porios de Inambari contra a política hegemônica de AG. Analogamente ao caso da estrada Interoceãnica Sul, a construção e operação da Usina Inambari pode ser entendida como um caso emblemático no cenário Latino Americano atual. Esta não seria apenas o maior projeto hidrelétrico da amazônia peruana, custando aproximadamente 4 bilhões de dolares e prometendo um potencial de geração de energia elétrica de cerca de 2.200 MW para exportar ao Brasil por ano, mas também concretizaria o vínculo energético estratégico entre estes dois países através de um complexo de usinas e linhas de transmissão interconectados. Para sua concretização se conta com o amparo financeiro e legislativo dos dois governos e suas instituições de fomento, além de instituições de internacionais de investimento (como o BID e o BM) e do capital internacional (este útlimo proveniente principalmente de empreiteiras brasileiras beneficiárias do modelo de concessões federais). Aqui se estudam os potenciais impactos na economia amazônica do modelo vigente de exploração de recursos naturais hídricos amazônicos através do caso INAMBARI. A conclusão aponta que inexistência de participação popular como o maior entrave ao desenvolvimento amazônico e tenta explicar a novaconfiguração dos movimentos sociais que buscam voz para os povos da Amazônia bem como o pioneirismo peruano em relação a lei de consulta prévia

Levantamento estrutural da porção norte do Greenstone Belt do rio Itapicuru e dos Alvos Encantado e C1W, Bahia

The study area is located in the geological context of the northern portion of the Rio Itapicuru Greenstone Belt (GBRI), located northeast of the São Francisco Craton, Bahia State. The GBRI is known for its great economic potential for gold mineralization, looking south at Fazenda Brasileiro Mine and North Mine Maria Preta, is situated in the study área. The structural pattern of the northern portion of the Greenstone, theme of this work, is of great importance to understand the mineralization present. To characterize the structural model three geologic sections (scale 1:25000) were made with NW-SE and EW directions and detailing two mineralized targets, Encantado, located northwest of the area, near the city of Nordestina, and C1W, located near Itapicuru River, west of the Maria Preta mine. Thus, field work and petrographic analysis were conducted, that allow to indicate the existence of two structural domains characterized by the existence of a main foliation, low angle dipping main foliation and another with high dip angle, both with NW, moreover, folds occur in the area Dn-1 and post-Dn folds. Dn-1 folds are observed less frequently but they occur mainly forming an oblique foliation and the Sn is present in porphyroblasts observed in petrographic analysis, whereas in relation to the folds post Dn, there are more than one type of folding in area, which differ by the orientation of their axis, a post Dn NS and EW Dn another post. Moreover, two areas of metamorphic green schist (biotite zone) and medium amphibolite, which are directly related to the structural domains found

Estudo da inflexão da Serra do Garrote e sua influência na zona de falha de Vazante (MG)

The Vazante Fault Zone (VFZ), located northwestward of Minas Gerais, host the largest zinc deposit known in the Brazilian territory. This structure is hosted in Vazante’s Group rocks, a metassedimentary sequence of marine environment. Near Vazante is situated the south end of the VFZ. To the west, occur the Serra do Garrote inflexion, characterized by a curvature in the contact of Formations Serra do Garrote and Serra do Poço Verde. This structure is through the analysis of aerial imagery of the region and represented in the published geological maps. The objective of this work is to understand what causes this inflexion and determine whether it affects the VZF, causing a shift in the same, and possibly, in the mineralization as well. To this end, it was done a mapping work in the region covering the Serra do Garrote inflexion and the south end of the VFZ, in 1:25.000 scale, supplemented by petrographic description of thin section and geologic sections, with cooperated to the understanding of the structural evolution of the region. Data analysis allowed the identification of six deformation phases. The D1 an D2 phases generated the main foliation. The D3 phase generate kink bands folds, with NS axis and vertical axial plane. The fourth phase is responsible for generating the Vazante Fault Zone. The fifth phase produces low angle folds and shear zones, subparallel to S1//S2. The last phase generates folds with NW axis and vertical axial plane, with causes the inflection of lithologic contactas. Field observations also make possible the conclusion that the Vazante Fault Zone presents a south continuation, which is affected by deformation associated to D6 phase attributing to the trace of the VFZ a curved geometry, similar to that exhibited by lithologic contacts between units of the map

Geologia e pesquisa mineral na região oeste do maciço Caritianas, municípios de Alto Paraíso e Itapuã D'Oeste, Rondônia

The granites Rondonianos, located in Rondônia Tin Pronvíncia, the southwestern portion of the Amazonian Craton, have great economic importance due to its large potential metallogenic. These granites stands out Intrusive Suite or Suite Granites Latest Rondônia Rondônia, with approximately 997-998 Ma (Bettencourt et al., 1997, 1999), for their tin mineralization having the largest reserves of this ore from Brazil. These tin mineralization in veins greissen are genetically related to these granites, deposits with different structural styles both within granitic plutons (endogreissen) as the host rocks (exogreissen). The western region of the Massif Caritianas has few published works, and the geology and potential econômicoão that were never fully known, now with the recovery of tin in the world market need new campaigns and prospective discoveries of new deposits
