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. 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

4. 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

5. 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

6. 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

7. 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-

8. Análise sismoestratigráfica dos carbonatos terciários da porção sul da Bacia de Santos / Sismoestratigraphy analisis of tertiary carbonates of South part of Santos Basin
Based on the sequence stratigraphy and on the excellent quality of the seismic data, a systematic study was used to better understand the development of the siliciclastic / carbonatic sedimentation of the southern portion of Santos Basin, occurred during Miocene. The database includes a multichannel seismic data, with approximately 500 km of linear data, and

9. 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

10. Aplicação da estratigrafia de sequências na seção albiana da porção sul da Bacia de Santos / Aplication of the stratigraphy of sequence on the albian section of the south portion of the Santos Basin
The main goal of this work is to detail the lower / middle Albian carbonatic section of Santos Basin based on the principles of Chemostratigraphy and Sequence Stratigraphy. Because this section was deposited under intense stress conditio ns (high salinity), its fossil content is very poor . It has limited the chronostratigraphic subdivision based only on bio

11. Sedimentação mista carbonato-siliciclástico durante o albo-aptiano na porção emersa da bacia Sergipe-Alagoas
The Albian-Aptian mixed sediments, composed of carbonate and siliciclastic constituents, occur in the onshore portion of the Sergipe-Alagoas Basin, next to its current border. Outcrops are located 50 km to northwest from Aracaju and, for the greater part, in oil well areas. The interpretations now presented are based on outcrop description, georadar sections

12. SeqÃÃncias siluro-devoniana e eocarbonÃfera da Bacia do ParnaÃba, Brasil, como anÃlogos para a explotaÃÃo de hidrocarbonetos
The present study was applied to understanding the similar hydrocarbon reservoirs on the Silurian, Devonian and Early Carboniferous sequences of the ParnaÃba Basin. The exposure investigated are located in the central area in the Piauà state. These outcrops are geologicaly inserted in the southeastern border of the ParnaÃba Basin. Three outcrops constitui
