1. Geochemistry, metamorphic evolution and tectonic significance of metabasites from Caçapava do Sul, southern Brazil
Abstract This paper proposes the generation and closure of a proto-ocean and formation of an island arc in the Neoproterozoic Passo Feio Metamorphic Complex (PFMC), Caçapava do Sul region, southern Brazil. The PFMC, São Gabriel Terrane, consists of a Neoproterozoic supracrustal metavolcano-sedimentary sequence intruded by the Caçapava Granite. The study u

2. Evolução estrutural das zonas de cisalhamento dúcteis na porção centro-leste do domínio da Zona Transversal na Província Borborema / Structural evolution of ductil shear zones on Central Eastern segment of transversal zone domain on Borborema Province
A área estudada está inserida no Domínio Transversal da Província Borborema. As unidades litoestratigráficas que compõem o embasamento paleoproterozócio (riaciano) são representadas por rochas ortoderivadas dos Complexos Salgadinho e Cabaceiras. Esses complexos foram individualizados de acordo com as suas diferenças composicionais, texturais e/ou ge

3. Ocorrência e significado dos Septos do embasamento encontrados nas suítes graníticas do Batólito Pelotas, RS, Brasil
The Pelotas Batholith situated in the eastern part of Sul-rio-grandense Shield is NE oriented and has dimensions of about 400 x 120 km. It is a granitic belt with six main suites: Pinheiro Machado Suite, Erval Suite, Viamão Suite, Encruzilhada do Sul Suite, Cordilheira Suite and Dom Feliciano Suite. The development of a continental collision whose evolution

4. Padrões de distribuição geográfica de linhagens intra-específicas e processos demográficos históricos em aves da floresta atlântica / Patterns of geographical distribution of intraspecific lineages and historical demography of Atlantic forest birds
This dissertation explores the evolution of Atlantic Forest (AF) organisms. Specifically, we used endemic forest birds as models and a phylogenetic phylogeographic perspective. Studied bird species are all passerines: Xiphorhynchus fuscus (Dendrocolaptidae), Dendrocolaptes platyrostris (Dendrocolaptidae) and Schiffornis virescens (Tytyridae). We used mitocho

5. Geologia do Terreno Paranaguá / Geology of Paranaguá Terrane
The Paranaguá Terrane is composed of precambrian geological units distributed in a NE-SW elongated swath, about 250 km long and 30 km wide, in south-southeastern Brazil, within the States of São Paulo (Nothern Paranaguá Terrane), Paraná and Santa Catarina (Southern Paranaguá Terrane). This terrane is constituted mainly by an igneous complex, represented

6. Evolução de terrenos tectono-metamórficos da Serrania do Ribeira e Planalto Alto Turvo (SP, PR) / Evolution of tectono-metamorphic terranes of the Ribeira Ridge and Alto Turvo Plateau, SE Brazil
Numerous Precambrian terranes of enigmatic origin are recognized in the Ribeira Valley and Alto Turvo Plateau regions (Southeastern Brazil), based on contrasting evolutive histories and distinct lithotectonic, metamorphic and structural patterns. These suspect terranes form three major composite terranes juxtaposed during the late Brasiliano Cycle: Apiaí Te

7. Cráton do São Franscisco, kimberlitos e diamantes
The São Francisco Craton is a large stable area in the eastern portion of South America. Its basement comprises Archean terrains that were reworked and amalgamated during Paleoproterozoic tectonic events and later on affected marginally by the Neoproterozoic Brasiliano orogeny, during the amalgamation of West Gondwana. In this work the geological evolution

8. Airbone geophysical and geologic data integration and its contribution the geodynamic evolution of central Ceara domain, Borborema Province / Integração de dados aerogeofisicos e geologicos e sua contribuição a evolução geodinamica do dominio Ceará Central, Provincia Borborema
Advances in airborne geophysical data processing techniques and their integration with geologic data allow recovering valuable information from both geophysical surveys and, the older technology. These information represent an essential tool for geologic-structural mapping of Pre-Cambrian terrains, where the stratigraphic and structural relations are difficu

9. Geologia do sudoeste do Estado de Goiás : Integração de dados geológicos e aerogeofísicos de alta densidade
The airborne magnetic and gamma ray spectrometry data related to the Airborne Geophysic Survey Project of the State of Goiás (Block 1) executed between 2004 and 2006 and considered of high density by the acquisition and treatment configuration, were integrated in GIS environment with the existing geologic information, in the SW Goiás region located from th

10. Mineralizações de ouro no terreno Almas-Dianópolis-TO : guias de exploração mineral
The distribution of the main gold occurrences and deposits of the Almas-Dianópolis Terrain (TAD), firstly evinced by recognition prospecting in drainage sediments, is controlled by N35-50W/N40-60E shear zones and, less frequently, by NS-shear zones. Gold essentially occurs in quartz veins bordered by albitic, argilic and sericitic alterations associated wit

Integração digital de imagens de radar e LANDSAT-TM com dados geológicos e aerogamaespectrométricos no auxílio ao mapeamento geológico da região do Complexo Granítico Estrela - Pará (PA) / Radar, geologic, airborne gamma ray and LANDSAT-TM digital data integration for geological mapping of the Estrela Granite Complex (PA).
This work is focused on the geotectonic context of the Carajás Mineral Province, Amazon Craton, which represents the most important Brazilian Mineral Province and hosts iron, cooper, gold, manganese and nickel deposits. At the end of Archean age, during the tecno-metamorphic evolution, moderated alkaline granitoids were generated, such as, Estrela Granite C
