The basement of the Punta del Este Terrane (Uruguay): an African Mesoproterozoic fragment at the eastern border of the South American Rio de La Plata craton

The Punta del Este Terrane (eastern Uruguay) lies in a complex Neoproterozoic (Brasiliano/Pan-African) orogenic zone considered to contain a suture between South American terranes to the west of Major Gercino-Sierra Ballena Suture Zone and eastern African affinities terranes. Zircon cores from Punta del Este Terrane basement orthogneisses have U-Pb ages of ca. 1,000 Ma, which indicate an lineage with the Namaqua Belt in Southwestern Africa. U-Pb zircon ages also provide the following information on the Punta del Este terrane: the orthogneisses containing the ca. 1,000 Ma inheritance formed at ca. 750 Ma; in contrast to the related terranes now in Africa, reworking of the Punta del Este Terrane during Brasiliano/Pan-African orogenesis was very intense, reaching granulite facies at ca. 640 Ma. The termination of the Brasiliano/Pan-African orogeny is marked by formation of acid volcanic and volcanoclastic rocks at ca. 570 Ma (Sierra de Aguirre Formation), formation of late sedimentary basins (San Carlos Formation) and then intrusion at ca. 535 Ma of post-tectonic granitoids (Santa Teresa and Jos, Ignacio batholiths). The Punta del Este Terrane and unrelated western terranes represented by the Dom Feliciano Belt and the Rio de La Plata Craton were in their present positions by ca. 535 Ma.

THE RIO APA CRATON IN MATO GROSSO DO SUL (BRAZIL) AND NORTHERN PARAGUAY: GEOCHRONOLOGICAL EVOLUTION, CORRELATIONS AND TECTONIC IMPLICATIONS FOR RODINIA AND GONDWANA

The Rio Apa cratonic fragment crops out in Mato Grosso do Sul State of Brazil and in northeastern Paraguay. It comprises Paleo-Mesoproterozoic medium grade metamorphic rocks, intruded by granitic rocks, and is covered by the Neoproterozoic deposits of the Corumbi and Itapocurni Groups. Eastward it is bound by the southern portion of the Paraguay belt. In this work, more than 100 isotopic determinations, including U-Pb SHRIMP zircon ages, Rb-Sr and Sm-Nd whole-rock determinations, as well as K-Ar and Ar-Ar mineral ages, were reassessed in order to obtain a complete picture of its regional geological history. The tectonic evolution of the Rio Apa Craton starts with the formation of a series of magmatic arc complexes. The oldest U-Pb SHRIMP zircon age comes from a banded gneiss collected in the northern part of the region, with an age of 1950 +/- 23 Ma. The large granitic intrusion of the Alumiador Batholith yielded a U-Pb zircon age of 1839 +/- 33 Ma, and from the southeastern part of the area two orthogneisses gave zircon U-Pb ages of 1774 +/- 26 Ma and 1721 +/- 25 Ma. These may be coeval with the Alto Terere metamorphic rocks of the northeastern corner, intruded in their turn by the Baia das Garcas granitic rocks, one of them yielding a zircon U-Pb age of 1754 +/- 49 Ma. The original magmatic protoliths of these rocks involved some crustal component, as indicated by the Sm-Nd TDm model ages, between 1.9 and 2.5 Ga. Regional Sr isotopic homogenization, associated with tectonic deformation and medium-grade metamorphism occurred at approximately 1670 Ma, as suggested by Rb-Sr whole rock reference isochrons. Finally, at 1300 Ma ago, the Ar work indicates that the Rio Apa Craton was affected by widespread regional heating, when the temperature probably exceeded 350 degrees C. Geographic distribution, age and isotopic signature of the fithotectonic units suggest the existence of a major suture separating two different tectonic domains, juxtaposed at about 1670 Ma. From that time on, the unified Rio Apa continental block behaved as one coherent and stable tectonic unit. It correlates well with the SW corner of the Amazonian Craton, where the medium-grade rocks of the Juruena-Rio Negro tectonic province, with ages between 1600 and 1780 Ma, were reworked at about 1300 Ma. Looking at the largest scale, the Rio Apa Craton is probably attached to the larger Amazonian Craton, and the actual configuration of southwestern South America is possibly due to a complex arrangement of allochthonous blocks such as the Arequipa, Antofalla and Pampia, with different sizes, that may have originated as disrupted parts of either Laurentia or Amazonia, and were trapped during later collisions of these continental masses.

Rhyacian (2.23-2.20 Ga) juvenile accretion in the southern Sao Francisco craton, Brazil: Geochemical and isotopic evidence from the Serrinha magmatic suite, Mineiro belt

The Serrinha magmatic suite (Mineiro belt) crops out in the southern edge of the Sao Francisco craton, comprising the Brito quartz-diorite, Brumado de Cima and Brumado de Baixo granodiorites, granophyres and felsic sub-volcanic and volcanic rocks, part of which intruded into the Nazareno greenstone belt. The suite rocks have petrographic features that are consistent with magma supercooling due to the low water content combined with volatile loss, leading to crystallization of quartz and alkaline feldspar at the rims of plagioclase phenocrysts (granophyric intergrowth). The investigated rocks are sub-alkaline, calc-alkaline and show low content in rare earth elements. The U-Pb zircon crystallization ages for the Brumado de Cima granodiorite [2227 +/- 22 (23) Ma] and a coeval granophyre [2211 +/- 22 (23) Ma], coupled with available single-zircon Pb evaporation ages for the Brito and Brumado de Baixo plutons, are significantly older than the ""Minas orogeny"" (ca. 2100-2050 Ga) of Quadrilatero Ferrifero area, eastward from the Serrinha suite. Our data establish an early Rhyacian event tectonically linked with the evolution of the Mineiro belt. The bulk Nd isotopic signature [low negative to positive epsilon(Nd(t)) values] of the Serrinha samples are consistent with the important role of Paleoproterozoic mantle components in the magma genesis. The integrated geologic, geochemical and isotopic information suggests that Paleoproterozoic evolution of the Mineiro belt initiated in a passive continental margin basin with deposition of the Minas Supergroup at ca. 2500 Ma. This stage was succeeded by outboard rupture of the oceanic lithosphere with development and coalescence of progressively younger magmatic arcs during Rhyacian time. One of the earliest arcs formed the Serrinha suite. The tectonic collage of the Serrinha and Ritapolis (2190-2120 Ma) arcs produced the NE-SW Lenheiro shear zone, resulting in mylonitization and recrystallization of both the granitoid intrusions and host rocks. As a matter of fact juxtaposition of distinct magmatic units in age and origin took place along the Lenheiros structure in this sector of the Mineiro belt. (C) 2009 Elsevier Ltd.

Chondrichthyans from the base of the Irati Formation (Early Permian, Parana Basin), Sao Paulo, Brazil

Three species of chondrichthyans are reported from conglomeratic sandstone at the base of the Lower Permian (Artinskian) Irati Formation (Parana Basin) near Rio Claro, Sao Paulo State, Brazil. The fossils include: 1) dispersed teeth of the petalodont ltapyrodus punctatus Silva Santos 1990, first described from the Permian (Artinskian) Pedra do Fogo Formation, Parnaiba Basin, Northeast Brazil; 2) a new species of tooth of the Order Orodontiformes; and 3) a new species of finspine of the Order Ctenacanthiformes. These fossils occur in an allochthonous assemblage of vertebrate remains including other Chondrichthyes, Xenacanthiformes and cladodonts, paleonisciform bony fish, and tetrapods. This discovery is a significant contribution to the sparse record of South American Chondrichthyes from the Early Permian and raises questions regarding the paleoenvironmental adaptations among these fish within Paleozoic basins of Brazil at this time.

Structural analysis of the Itapucumi Group in the Vallemi region, northern Paraguay: Evidence of a new Brasiliano/Pan-African mobile belt

The Neoproterozoic (Ediacaran) Itapucumi Group in northern Paraguay is composed of carbonate and siliciclastic rocks, including ooid grainstones, marls, shales and sandstones, containing Cloudina fossils in the eastern region. It is almost undeformed over the Rio Apa Cratonic Block but shows a strong deformational pattern at its western edge. A detailed structural analysis of the Itapucumi Group was conducted in the Vallemi Mine, along with a regional survey in other outcrops downstream in the Paraguay River and in the San Alfredo, Cerro Paiva and Sargent Jose E. Lopez regions. In the main Vallemi quarry, the structural style is characterized by an axial-plane slaty cleavage in open to isoclinal folds, sometimes overturned, associated with N-S trending thrust faults and shear zones of E-vergence and with a low-grade chlorite zone metamorphism. The structural data presented here are compatible with the hypothesis of a newly recognized mobile belt on the western side of the Rio Apa Cratonic Block, with opposite vergence to that of the Paraguay Mobile Belt in Brazil. Both belts are related to the Late Brasiliano/Pan-African tectonic cycle with a Lower Cambrian deformation and metamorphism age. The deformation could be due to the late collision of the Amazonian Craton with the remainder of Western Gondwana or to the western active plate boundary related to the Pampean Belt. The structural and lithologic differences between the western Itapucumi Group in the Vallemi and Paraguay River region and the eastern region, near San Alfredo and Cerro Paiva, suggest that this group could be divided into two lithostratigraphic units, but more stratigraphic and geochronological analyses are required to confirm this possibility.

Well-preserved Late Paleoproterozoic volcanic centers in the Sao Felix do Xingu region, Amazonian Craton, Brazil

The Amazonian craton in the Sao Felix do Xingu city, southeast region of the Para state, north of Brazil, hosts exceptionally well-preserved Paleoproterozoic bimodal magmatic units grouped in the Sobreiro and Santa Rosa formations. These formations are correlated to the Uatuma magmatic event, which is largely distributed in the Amazonian craton occupying more than 1,500,000 km(2). Geological mapping and petrographical observations reveal distinct spectra of volcanic facies in both formations. The basal calc-alkaline Sobreiro Formation is composed mainly of andesitic and dacitic lava flows and associated volcaniclastic facies of autoclastic origin, with subordinate pyroclastic flow deposits. This formation shows inferred eruption style that is similar to those in Flood Basalt Provinces, with rare scutulum-type lava shields. The upper A-type Santa Rosa Formation was generated by multicyclic explosive and effusive episodes predominantly associated with large fissures and is materialized by voluminous ignimbrites with subordinated ash-fall tuff, crystal tuff, lapilli-tuff, co-ignimbritic breccias, rhyolitic dikes and domes, and associated granitic porphyries and equigranular granitic intrusions. Ignimbrite and rhyolite dikes reveal conspicuous vertical flow pattern pointing to a fissure-controlled eruption, similar to Sierra Madre Occidental ignimbrite province. The proposed evolutionary model for the Sao Felix do Xingu units differs from those of other occurrences related to the Uatuma magmatic event in the Amazonian craton, characterized by predominance of A-type volcanism and contemporaneous granites.

Determination of anthropogenic and biogenic compounds on atmospheric aerosol collected in urban, biomass burning and forest areas in Sao Paulo, Brazil

This study was conducted at three sites of different characteristics in Sao Paulo State Sao Paulo (SPA), Piracicaba (PRB) and Mate Atlantica Forest (MAT) PM(10), n-alkanes. pristane and phytane, PAHs, water-soluble ions and biomass burning tracers like levoglucosan and retene, were determined in quartz fiber filters. Samplings occurred on May 8th to August 8th, 2007 at the MAT site; on August 15th to 29th in 2007 and November 10th to 29th in 2008 at the PRB site and, March 13th to April 4th in 2007 and August 7th to 29th in 2008 at the SPA site Aliphatic compounds emitted biogenically were less abundant at the urban sites than at the forest site, and its distribution showed the influence of tropical vascular plants Air mass transport front biomass burning regions is likely to impact the sites with specific molecular markers The concentrations of all species were variable and dependent of seasonal changes In the most dry and polluted seasons, n-alkane and canon total concentrations were similar between the megacity and the biomass burning site PAHs and inorganic ion abundances were higher at Sao Paulo than Piracicaba, yet, the site influenced by biomass burning seems lobe the most impacted by the organic anion abundance in the atmosphere Pristane and phytane confirm the contamination by petroleum residues at urban sites, at the MAT site, biological activity and long range transport of pollutants might influence the levels of pristane (C) 2010 Elsevier B V All rights reserved

Mutagenicity and DNA adduct formation of PAH, nitro-PAH, and oxy-PAH fractions of atmospheric particulate matter from Sao Paulo, Brazil

Urban particulate matter (UPM) contributes to lung cancer incidence. Here, we have studied the mutagenic activity and DNA adduct-forming ability of fractionated UPM extractable organic matter (EOM). UPM was collected with a high-volume sampler in June 2004 at two sites, one at street level adjacent to a roadway and the other inside a park within the urban area of the city of Sao Paulo, Brazil. UPM was extracted using dichloromethane, and the resulting EOM was separated by HPLC to obtain PAH, nitro-PAH, and oxy-PAH fractions which were tested for mutagenicity with the Salmonella strains TA98 and YG1041 with and without S9 metabolic activation. The PAH fraction from both sites showed negligible mutagenic activity in both strains. The highest mutagenic activity was found for the nitro-PAH fraction using YG1041 without metabolic activation; however, results were comparable for both sites. The nitro-PAH and oxy-PAH fractions were incubated with calf thymus DNA under reductive conditions appropriate for the activation of nitro aromatic compounds, then DNA adduct patterns and levels were determined with thin-layer chromatography (TLC) (32)p-postlabeling method using two enrichment procedures-nuclease PI digestion and butanol extraction. Reductively activated fractions from both sites produced diagonal radioactive zones (DRZ) of putative aromatic DNA adducts on thin layer plates with both enrichment procedures. No such DRZ were observed in control experiments using fractions from unexposed filters or from incubations without activating system. Total adduct levels produced by the nitro-PAH fractions were similar for both sites ranging from 30 to 45 adducts per 10(8) normal nucleotides. In contrast, the DNA binding of reductively activated oxy-PAH fractions was three times higher and the adduct pattern consisted of multiple discrete spots along the diagonal line on the thin layer plates. However, DNA adduct levels were not significantly different between the sampling sites. Both samples presented the same levels of mutagenic activity. The response in the Salmonella assay was typical of nitroaromatics. Although, more mutagenic activity was related to the nitro-PAH fraction in the Salmonella assay, the oxy-PAH fractions showed the highest DNA adduct levels. More studies are needed to elucidate the nature of the genotoxicants occurring in Sao Paulo atmospheric samples. (C) 2008 Elsevier B.V. All rights reserved.

Conformational differences between the wild type and V30M mutant transthyretin modulate its binding to genistein: Implications to tetramer stability and ligand-binding

Transthyretin (TTR) is a tetrameric beta-sheet-rich transporter protein directly involved in human amyloid diseases. It was recently found that the isoflavone genistein (GEN) potently inhibits TTR amyloid fibril formation (Green et al., 2005) and is therefore a promising candidate for TTR amyloidosis treatment. Here we used structural and biophysical approaches to characterize genistein binding to the wild type (TTRwt) and to its most frequent amyloidogenic variant, the V30M mutant. In a dose-dependent manner, genistein elicited considerable increases in both mutant and TTRwt stability as demonstrated by high hydrostatic pressure (HHP) and acid-mediated dissociation/denaturation assays. TTR:GEN crystal complexes and isothermal titration calorimetry (ITC) experiments showed that the binding mechanisms of genistein to the TTRwt and to V30M are different and are dependent on apoTTR structure conformations. Furthermore, we could also identify potential allosteric movements caused by genistein binding to the wild type TTR that explains, at least in part, the frequently observed negatively cooperative process between the two sites of TTRwt when binding ligands. These findings show that TTR mutants may present different ligand recognition and therefore are of value in ligand design for inhibiting TTR amyloidosis. (C) 2010 Elsevier Inc. All rights reserved.

Uso de sistemas de informação geografica como subsidio ao planejamento em areas agricolas : um caso no planalto do Rio Grande do Sul

Os Sistemas de Informação Geográfica vêm sendo cada vez mais utilizados em estudos envolvendo o planejamento e gerenciamento de recursos e meio-ambiente. A agricultura é uma das atividades humanas mais intimamente relacionadas com o meio ambiente. Este trabalho investiga o emprego desses sistemas para integrar diferentes informações relacionadas à produção agrícola e obter respostas que subsidiem o planejamento em regiões agrícolas.A área estudada é uma localidade do município de Não-me-Toque, situado no planalto médio do Rio Grande do Sul, entre as coordenadas 28°21' e 28°34'sul e 53°40' e 53°57'oeste. Os resultados evidenciaram as vantagens dos Sistemas de Informação Geográfica sobre os métodos convencionais de análise, especialmente no que se refere à velocidade, precisão e à associação dos dados de interesse à sua localização geográfica.

Bioclastos de organismos terrestres e marinhos na praia e plataforma interna do Rio Grande do Sul : natureza, distribuição, origem e significado geológico

Fácies marinhas e costeiras associadas a eventos transgressivos-regressivos quaternários ocorrem na Planície Costeira do Rio Grande do Sul e na plataforma continental adjacente. Enquanto as fácies expostas na planície costeira apresentam uma composição essencialmente siliciclástica, as fácies submersas, hoje aflorantes na antepraia e plataforma interna, apresentam, muitas vezes, uma composição carbonática. Formada por coquinas e arenitos de praia fortemente cimentados, estas fácies destacam-se do fundo oceânico como altos topográficos submersos. Os altos topográficos da antepraia têm atuado como fonte de boa parte dos sedimentos e bioclastos de origem marinha encontrados nas praias da área de estudo. Os bioclastos carbonáticos que ocorrem nestes locais caracterizam uma Associação Heterozoa, ou seja, são formados por carbonatos de águas frias, característicos de médias latitudes, e são representados principalmente por moluscos, equinodermos irregulares, anelídeos, crustáceos decápodos, restos esqueletais de peixes ósseos e cartilaginosos, cetáceos, tartarugas e aves semelhantes à fauna atual. Além destes bioclastos de origem marinha, as praias estudadas apresentam a ocorrência de fragmentos orgânicos provenientes de afloramentos continentais fossilíferos, contendo abundantes restos esqueletais de mamíferos terrestres gigantes extintos, das ordens Edentada, Notoungulada, Litopterna, Proboscidea, Artiodactila, Perissodactila, Carnívora e Rodentia. A concentração dos bioclastos na praia resultada da ação direta dos processos hidrodinâmicos que atuam na região de estudo (ondas de tempestade, deriva litorânea, correntes, etc). A variação no tamanho médio dos bioclastos encontrados ao longo da linha de costa está relacionada ao limite da ação das ondas de tempestades sobre o fundo oceânico, o qual é controlado principalmente pela profundidade. Os afloramentos-fonte submersos podem ser divididos em holocênicos e pleistocênicos. A tafonomia dos bioclastos pleistocênicos permite argumentar que após o penúltimo máximo transgressivo que resultou na formação do sistema deposicional Laguna-Barreira III (aproximadamente 120 ka) parte dos depósitos lagunares permaneceram emersos e não estiveram sob a ação marinha (barrancas do arroio Chuí, com a megafauna preservada in situ), enquanto que parte dos depósitos lagunares esteve sob ação direta do ambiente praial. Em diversas feições submersas observam-se coquinas contendo fósseis de mamíferos terrestres, indicando o retrabalhamento dos sedimentos lagunares em ambiente praial. As coquinas que apresentam moluscos pouco arredondados e de maior granulometria são aqui definidas, informalmente, como Coquinas do Tipo 1. Como conseqüência da última regressão pleistocênica (iniciada após o máximo transgressivo de 120 ka) estas coquinas ficaram submetidas a uma exposição subaérea. Este fato possibilitou a dissolução diferenciada dos componentes carbonáticos existentes nos depósitos (coquinas e arenitos) e sua recristalização (calcita espática) em ambientes saturados em água doce. A Transgressão Pós-Glacial (iniciada em torno de 18 ka) foi responsável pelo retrabalhamento dos arenitos e coquinas, recristalizando mais uma vez os elementos carbonáticos. Devido ao seu grau de consolidação estes depósitos resistiram à erosão associada à elaboração da superfície de ravinamento e encontram-se atualmente expostos na antepraia e, mesmo, na linha de praia atual. Pelo menos há 8 ka houve novamente um período favorável à precipitação de carbonato de cálcio, ocorrendo a litificação de rochas sedimentares em uma linha de praia numa cota batimétrica inferior a atual. Neste intervalo de tempo formaram-se as coquinas e arenitos não recristalizados, apresentando fragmentos de moluscos muito fragmentados e arredondados e de menor granulometria, aqui definidas, informalmente, como Coquinas do Tipo 2. A interpretação da tafonomia dos bioclastos de idade holocênica sugere pelo menos duas fácies deposicionais: (a) Fósseis articulados numa matriz areno-síltica, preenchidos por silte e argila, interpretados como originalmente depositados em regime transgressivo no ambiente Mesolitoral (foreshore) para Infralitoral superior (upper shoreface), com baixa ação de ondas. (b) Fragmentos de carapaças e quelas isoladas encontradas numa coquina fortemente cimentada por calcita espática, por vezes recristalizada, interpretados como concentrados na Zona de Arrebentação por ondas de tempestades. A dinâmica costeira atual retrabalha novamente os sedimentos inconsolidados enquanto as rochas sedimentares consolidadas (formadas pelas Coquinas Tipo 1 e 2) resistem parcialmente à erosão e constituem os altos topográficos submersos (parcéis) descritos neste trabalho.

Impactos regionais de mudanças tecnológicas na agropecuária : região celeiro do Rio Grande do Sul

Este trabalho tem o objetivo de criar cenários com propostas tecnológicas para Região Noroeste do Rio Grande do Sul, sub-região Celeiro. Avaliar o impacto das tecnologias sobre a renda regional e sobre a ocupação da mão-de-obra rural, testando as orientações técnicas quanto ao direcionamento dos beneficiários, visto que a proposta de melhorar o nível sócio-econômico dos pequenos estabelecimentos rurais é preconizada pela Extensão Rural e Assistência Técnica regional. Para tal, a metodologia adotada foi a montagem de um modelo de programação linear, estratificando os estabelecimentos rurais por área e submetendo-os às técnicas propostas e comparando-as com a realidade regional. Ao final do trabalho, verificou-se que as técnicas propostas elevam a renda regional e reduzem o nível de ocupação da mão-de-obra rural. As grandes propriedades são favorecidas com a implementação das tecnologias em detrimento das pequenas, que passam a ter uma participação menor na formação da Renda Regional. O nível de ocupação da mão-de-obra nos estratos menores diminui, o que contrapõe as políticas regionais e nacionais quanto à redução do êxodo rural.

Um estudo do perfil demandado pelo mercado de trabalho para os alunos egressos da Escola Técnica da Universidade Federal do Rio Grande do Sul

A educação profissional no Brasil sempre esteve voltada para o desenvolvimento de aptidões para a vida produtiva. A rapidez das transformações tecnológicas, entretanto, passou a exigir dos profissionais de nível técnico uma qualificação atualizada, que atenda às dinâmicas exigências do mundo do trabalho. Além disso, a recente reforma na legislação básica do ensino profissional concedeu relativa autonomia às instituições de ensino, tanto para a organização e o planejamento de seus cursos quanto para a sua adequação às demandas dos setores produtivos. Daí a necessidade de se implantarem mecanismos permanentes de consulta a fim de avaliar os atributos valorizados pelo mercado de trabalho, a exemplo do que propõe o estudo de caso desta dissertação. Para definir o perfil do egresso demandado pelo mercado de trabalho, foram pesquisadas as empresas potencialmente interessadas em contratar egressos da Escola Técnica da Universidade Federal do Rio Grande do Sul, instituição que tradicionalmente forma recursos humanos com vistas ao mercado de trabalho. A partir dos resultados obtidos com o levantamento, foram elaboradas sugestões no sentido de adequar o perfil das habilitações oferecidas às demandas de mercado, considerando as diferentes áreas profissionais desenvolvidas na Escola Técnica.
