1. Microfacies and diagenetic evolution of the limestones of the upper part of the Crato Formation, Araripe Basin, northeastern Brazil
Abstract This paper presents the results of a petrographic and diagenetic study of the laminated limestones of the upper part of the Aptian to Albian Crato Formation, northeast of Brazil. The applied techniques were optical microscopy, cathodoluminescence and scanning electron microscopy (SEM) coupled to a wavelength-dispersive spectrometer (WDS). Petrograph

2. Estudo diagenético aplicado ao Membro Maruim da Formação Riachuelo , na parte terrestre da sub-bacia de Sergipe, Brasil / Diagenetic study applied to Maruim Member (Riachuelo Formation) in the onshore part of the Sergipe sub-basin
O Membro Maruim da Formação Riachuelo (Neoalbiano), na parte terrestre da Sub-bacia de Sergipe, contém fácies de água rasa compostas, principalmente, por rudstone/grainstone oncolítico oolítico, com baixo conteúdo e variedade de bioclastos. A correlação dos afloramentos e análise petrográfica detalhada, envolvendo catodoluminescência, microscopi

3. Padrões diagenéticos em arenitos de sistemas de Sabk ha costeiros-eólicos: um estudo comparativo dos reservatórios Juruá da área de Urucu, Bacia de Solimões, AM
Coastal-eolian sabkha sandstones from different ages and basins show similar diagenetic patterns, which understanding is important for their evaluation as geochemical systems and as hydrocarbon reservoirs. The Carboniferous sandstones of the Juruá Formation (Solimões Basin) are one of the most important gas reservoirs of Brazil. The sandstones and interbed

4. Estudo sobre a evolução do aporte natural e antrópico de matéria orgânica para sedimentos de um sistema estuarino- lagunar tropical (Mundaú-Manguaba, Alagoas) utilizando lipídios como marcadores moleculares / Study on the evolution of natural and anthropogenic inputs of organic matter for sediments of a tropical lagoon-estuarine system (Mundaú-Manguaba, Alagoas) using lipids as molecular markers
This thesis presents a study on the accumulation of organic matter in the sediments of the complex estuarine lagoon Mundaú Manguaba (CELMM) using lipids (fatty acids, sterols and linear alcohols) as molecular markers to evaluate the sources (natural and anthropogenic) and spatial and temporal variation in the composition of sedimentary organic matter, as we

5. Caracterização mineralógica e tecnológica dos lutitos diatomáceos da Península de Santa Elena, Equador
The diatoms lutite, that had been studied in this these, are inserted in the Villingota Member of the Tosagua Formation, in the Progreso Basin, in the Santa Elena Peninsula, that constitutes an important area located to the southwest of the coast of Ecuador. Arenites in some levels of the Tosagua Formation had also been researched, which had its presence as

6. Evolução diagenética das formações Pirambóia e Botucatu (Sistema Aqüífero Guarani) no Estado de São Paulo / Diagenetic evolution of Pirambóia and Botucatu formation (Guarani Aquifer System) in the São Paulo State
A investigação das rochas das formações Pirambóia e Botucatu em subsuperfície foi realizada através da revisão, coleta e análise de amostras de calha de poços de captação de água no interior do Estado de São Paulo, além de dados de poços de petróleo da Bacia do Paraná, com o objetivo de delinear a evolução diagenética destas unidades e i

7. ASSESSMENT OF THE DEGRADATION OF OIL IN MANGROVE SEDIMENT: STUDY CASE, GUANABARA BAY / AVALIAÇÃO DA DEGRADAÇÃO DE ÓLEO EM SEDIMENTOS DE MANGUEZAL: ESTUDO DE CASO, BAÍA DE GUANABARA, RJ
Brazil is observing an increasing growth in the petroleum industry resulting in an equally increased risk of accidents involving petroleum and derivatives. A great part of the Brazilian coastal plain is covered by mangroves, which are an important ecosystem for procreation and preservation of marine and terrestrial species. As a result it is urgent the need

8. DEPOSIÇÃO E EVOLUÇÃO DIAGENÉTICA DOS RESERVATÓRIOS DO MEMBRO MUCURI (CRETÁCEO INFERIOR), NOS CAMPOS DE RIO PRETO E SÃO MATEUS, BACIA DO ESPÍRITO SANTO, BRASIL
The Mucuri Member represents the rift phase of the Espírito Santo Basin stratigraphic column. It is considered one of the best oil reservoirs in the emerse portion of the basin, where the fields of the Rio Preto and Sao Mateus are located. Within the Mucuri Member, 14 litofacies were identified. These litofacies include conglomerates, shales and even evapor

9. Oceanic minerals: Their origin, nature of their environment, and significance
The chemical and isotopic compositions of oceanic biogenic and authigenic minerals contain invaluable information on the evolution of seawater, hence on the history of interaction between tectonics, climate, ocean circulation, and the evolution of life. Important advances and greater understanding of (a) key minor and trace element cycles with various r
