1. 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

2. Geoquímica e geocronologia sedimentarno estudo das sequências paleozoica e pré-rifte de bacias do nordeste brasileiro
Integrated application of geochemical and sedimentary geochronology in pelitic rock samples from the basal section of the northeastern Brazilian continental margin, especially those of the Paleozoic and pre-rift sequences is the main goal of this thesis. The results are presented and discussed in three technical articles. Two of these articles present the Rb

3. Significados paleoambientais e paleoclimáticos dos Paleossolos : uma revisão
The majority of paleosols are described from continental deposits, most commonly from alluvial strata. In these continental records to much little is revealed of conditions between events of sedimentation. In alluvial sedimentary environments, a record of these conditions is not lost and gone forever. They may be interpreted from fossil soils formed on depos

4. Estratigrafia de seqüências aplicada à caracterização de aqüíferos: um estudo de caso na área de Candiota, Rio Grande do Sul
Detailed stratigraphic analysis of the Early Permian (Artinskian/Kungurian) succession of the intracratonic Paraná Basin in southernmost Brazil has been applied focusing stratigraphic characterization of potential aquifers. In the study area, the counties of Candiota and Hulha Negra, in the southwestern region of Rio Grande do Sul state, the sedimentary suc

5. Aplicação da estratigrafia de sequências para caracterização em multiescala de reservatórios no Grupo Guatá (Eopermiano da Bacia do Paraná) na Região São Gabriel-RS, Brasil
Detailed stratigraphic analysis of the Early Permian Rio Bonito and Palermo Formations of the intracratonic Paraná Basin in the region of São Gabriel County has been used for a study on reservoir characterization of paralic sandstones. Two main depositional systems were recognized, a fluvial-dominated delta system at the base and a wavedominated barrier is

6. Diferenças entre os depósitos auríferos do Grupo Aguapei (Estado de Mato Grosso) e os exemplos de ouro em conglomerados
Gold prospects in the Aguapeí Folded Belt are situated in the southwestern portion of the Amazon Craton, within the Alto Guaporé Province, southwestern state of Mato Grosso. The mineralizations are mainly concentrated in the Pau-a-Pique Deposit (south), Lavrinha Region (central), and São Vicente Mine (north). Gold ore comprises quartz veins and disseminat

7. Estratigrafia de sequências do intervalo aptiano ao albino na Bacia do Araripe, NE do Brasil / Estratigrafia de sequências do intervalo aptiano ao albino na Bacia do Araripe, NE do Brasil
This study has as a main objective to make a detailed stratigraphic analysis of the Aptian-Albian interval in the east part of Araripe Basin, NE of Brazil which correspond, litostratigraphically, to Rio Da Batateira, Crato, Ipubi and Romualdo formations. The stratigraphic analysis was based on three different stages, the 1D, 2D and 3D analysis; these ones we

8. Radioatividade de rochas provenientes das formações geológicas pertencentes à bacia hidrográfica do Rio Tibagi
This work is a study of the 40K and the 238U and 232Th series radioactivity in rocks measured with high resolution gamma ray spectrometry. The rocks were taken from the geologic formations in the region of the Tibagi river hydrographic basin. The course of this river cuts through the Paleozoic and Mesozoic stratigraphic sequences of the Paraná sedimentary b

9. Caracterização tectono-estratigráfica da sequência transicional na sub-bacia de Sergipe
This thesis deals with the tectonic-stratigraphic evolution of the Transitional Sequence in the Sergipe Sub-basin (the southern segment of the Sergipe-Alagoas Basin, Northeast Brazil), deposited in the time interval of the upper Alagoas/Aptian stage. Sequence boundaries and higher order internal sequences were identified, as well as the structures that affec

10. High resolution stratigraphy framework for carbonatic deposits of terciary of the Basin Campos / Geração de um arcabouço estratigráfico de alta resolução para depósitos carbonáticos terciários da Bacia de Campos
The Siri Member is of great importance due to the heavy oil content that is present on the carbonate platform developed during the Tertiary. Considering this importance, we conducted a study with the objective of generating a high resolution stratigraphic framework, on 3rd order sequences, using the interpretation of two seismic sections and the analysis of

11. Análise estratigráfica de alta resolução do intervalo praguiano-neoemsiano (Formação Ponta Grossa), na borda leste da Bacia do Paraná, com base em dados geoquímicos e sedimentológicos / High resolution stratigraphic analysis of praguian-neoemsian interval (Ponta Grossa Formation), at eastern edge of Parana Basin, with base on geochemical and sedimentologic datas
This work is the result of detailed stratigraphic analysis on the sedimentary record of Praguian?Emsian later interval, established on core samples of four wells in the Paleozoic outcrop section, eastern edge of Paran? Basin. Data set was obtained by means of sedimentology, gamma spectrometry and organic geochemistry (total organic carbon and pirolysis Rock-

12. 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
