13. 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

14. "Aplicação de marcadores orgânicos moleculares em estudos oceanográficos e paleoceanográficos: estudo de caso na Margem Continental Superior do Sudeste do Brasil" / Molecular Organic Markers Application in Oceanographic and Paleoceanographic Studies: Case study at the Southeastern Brazilian Continental Margin
Climatic changes produce environmental signatures with which it is possible to reconstruct past environmental conditions. In the ocean, the fate of most of the organic matter is the marine sediment. Sediment core analyses reveal a unique reservoir of biological, chemical and geological information about past processes and how they responded to the environmen

15. Contributions to South Atlantic paleoceanography in the last 25,000 years: evidence from calcareous nannofossils from northeastern brazilian slope / Nanofósseis calcários da margem continental nordeste do Brasil: uma contribuição à paleoceanografia do Atlântico Sul nos últimos 25.000 anos
This study focuses on changes in calcareous nannofossil assemblages as an evidence of paleoceanographic variability during the last 25,000 years in two deep sea piston cores from the northeastern Brazilian continental margin. To support reconstructing ancient marine environment others proxies have been applied along with the calcareous nannofossil analysis:

16. Distribution of planctonic foraminifera (0 m - 100 m in the water column) and theirsedimentary record on the Southeastern Brazilian continental margin, between São Sebastião Island, SP, and São Tomé Cabe, RJ / "Distribuição de foraminíferos planctônicos (0 - 100m na coluna dágua) e seu registro no sedimento na margem continental sudeste brasileira, entre São Sebastião, SP, e Cabo de São Tomé, RJ"
The present work focuses on the study of planktonic foraminifera on the southeast Brazilian continental margin between São Sebastião, SP and São Tomé, RJ. This was done by means of a survey of the existing species in the plankton. The seasonal and vertical distribution in the water column (0-100 m depth) of the planktonic foraminifera species was also de

17. Litoestratigrafia e deformação cenzóica na região de Icapuí, Ceará, e implicações para a estruturação de campos de petróleo na borda ocidental da bacia Potiguar(NE do Brasil)
This thesis deals with the sedimentological/stratigraphic and structural evolution of the sedimentary rocks that occur in the NW continental border of the Potiguar Basin. These rocks are well exposed along coastal cliffs between the localities of Lagoa do Mato and Icapuí, Ceará State (NE Brazil). The sedimentological/stratigraphic study involved, at the ou
