1. 3-D Geological modelling: a siliciclastic reservoir case study from Campos Basin, Brazil
Abstract Reservoir static modelling plays a fundamental role in the evaluation phase of a petroleum field. Integrated modelling allows a better understanding of how the local geology and depositional systems are related through the distribution of facies and petrophysical properties within the reservoir. In this study, geological static models of the silicic

2. Geomorfologia, estratigrafia de sequências e potencial de preservação dos sistemas Laguna Barreira do Quaternário Costeiro do Rio Grande do Sul.
The stratigraphic record of Rio Grande do Sul Coastal Plain embraces four high-frequency depositional sequences corresponding to four barrier-lagoon systems (I to IV). These sequences have been developed during the Pleistocene and Holocene, in response to glacioeustatic cycles of 100 ka. The Holocene coastal system, related to the younger sequence (IV), exhi

3. Raciocínio sobre conhecimento visual : um estudo em estratigrafia sedimentar / Reasoning over visual knowledge: a study in sedimentary stratigraphy
Imagistic domains are those in which problem-solving process begins with the recognition of domain objects trough the visual information captured, supporting more abstract interpretations in subsequent steps. The problem-solving process, in imagistic domains, is performed trough intensive application of visual knowledge, which corresponds to the set of menta

4. Tectônica e sedimentação na Bacia do Camaquã Central (RS): exemplos do Grupo Guaritas e do Grupo Santa Bárbara / Tectonics and sedimentation in Central Camaquã Basin: the Guaritas Group and the Santa Bárbara Group
The relationship between tectonics and sedimentation plays a primordial role in the understanding of sedimentary successions. On the other hand, the study of pre-Silurian fluvial deposits represents a challenge due to the lack of interaction between land plants and river systems which characterizes post-Silurian environments. The Camaquã Basin (Ediacaran to

5. Desenvolvimento de equipamento para realização de ensaios HCT com o uso da bomba de fluxo
In general, the tailings are disposed in the form of pulp, mainly because the condition of the residue is the natural byproduct of the minerals concentrations activities, always associated with large water demands. The final disposal of wastes in pulp occurs by hydraulic filling techniques in large reservoirs of check dams. In the case of more granular taili

6. Influência de níveis de base nas características morfossedimentares das bacias dos rios das Velhas e Jequitaí (MG)
The Velhas and Jequitaí river basins have together an asymmetric shape that drain northward from Quadrilátero Ferrífero to the northern Minas Gerais State. These two basins are affluent of São Francisco river in its right margin. The headwaters of Velhas and Jequitaí rivers are dominated by quartzites ridges structured during the Brazilian orogenic cycl

7. Flood-dominated fluvio-deltaic system: a new depositional model for the Devonian Cabeças Formation, Parnaíba Basin, Piauí, Brazil
O modelo deposicional da Formação Cabeças é reinterpretado no presente estudo com base no contexto paleogeográfico da Bacia do Parnaíba durante o Devoniano e na similaridade entre as fácies encontradas na Formação Cabeças com as fácies características dos sistemas flúvio-deltaicos dominados por inundações. O tipo das clinoformas sigmoidais (co

8. Analise de facies e modelo paleodeposicional da plataforma siliciclastica ordoviciana da Pre-Cordilheira Argentina / Facies analisys and paleodepositional model of the ordovician siliciclastic shelf of the Argentine Precordillera
This work consists in the study of sedimentological and paleodepositional features of four Ordovician lithostratigraphic units of the Precordillera Argentina: Portezuelo del Tontal Formation (PTF), Sierra de La Invernada Formation (SIF), Gualcamayo Formation (GF) and Los Azules Formation (LAF). The PTF is represented by alternating fine- to very fine grained

9. Sediment distribution model in marine shelf area : a cambrian example from the Sergipano Belt (Lagarto Formation, Estancia Domain, Sergipe) / Modelo de distribuição de sedimento em area de plataforma marinha : um exemplo do cambriano da faixa sergipana (Formação Lagarto, Dominio Estancia, Sergipe)
Coastal areas of wave-influenced tidal plains are not well known in recent and ancient depositional systems. The Lagarto Formation represents one of these mixed depositional systems influenced both by tide and wave activities. This work describes the sediments in this system, interprets the depositional processes and defines a distributional model of sedimen

10. DinÃmica GeomorfolÃgica do Ambiente de Encosta em Brejo da Madre de Deus - PE: uma abordagem a partir da perspectiva morfoestratigrÃfica aplicada aos depÃsitos coluviais
This present research tried to evaluate the geomorphological dynamic of the elevated compartments of the Borborema Highlands prioritizing the occurrence of sedimentary deposits dated that were identified after a qualitative rising of the geomorphological features. The chosen area type was the district of Tabocas, in the municipal district of Brejo da Madre d

11. Sedimentary facies and provenance of the Bebedouro Formation, Neoproterozoic (BA) / Fácies sedimentares e proveniência da Formação Bebedouro, Neoproterozóico (BA)
The sedimentary record of Neoproterozoic age has become a major subject of research since the rebirth of the models of extreme glaciation and rapid climatic changes for the period, including the Snowball Earth hypothesis. These models are founded on the identification, in all continents, of Neoproterozoic diamictites directly overlain by carbonates, which ar

12. A história do intemperismo na Província Borborema Oriental, Nordeste do Brasil: implicações paleoclimáticas e tectônicas
Until some years ago, weathering geochronology was primarily based on the K-Ar and 40Ar/39Ar dating of supergene minerals. Recent advances in the analysis of supergene goethite by the (U-Th)/He method expanded the number of suitable minerals for such purpose, as well as the time of application for weathering geochronology. This study represents the first sys
