1. Análise da deformação pós-Rifte na Bacia do Araripe, Nordeste do Brasil
The Araripe Basin is located over Precambrian terrains of the Borborema Province, being part of Northeast Brazil inner basins. Its origin is related to the fragmentation of the Gondwana supercontinent and consequently opening of South Atlantic during early Cretaceous. The basin has a sedimentary infill encompassing four distinct evolution stages, comprising

2. Tectônica e sedimentação do Grupo Jacadigo (Neoproterozóico, MS) / Tectonics and sedimentation of Jacadigo Group (Neoproterozoic, MS)
At the south of Corumbá, Mato Grosso do Sul state, there are huge topographic elevations made of Jacadigo Groups neoproterozoic sedimentary deposits. Those mountains are known as Maciço do Urucum. The basal unit named Urucum Formation is composed by siliciclastic rocks with maximum thickness of 200 to 300m. The sucession continues with mixed GIF (granular

3. 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

4. Mineralização aurifera de Lages-Antonio Dias, Ouro Preto-MG controles lito-estratigraficos e estruturais
The Lages-Antônio Dias area is eomprised within the Ouro Preto mountain range, Minas Gerais. The area hosts a number of aneient, abandoned gold mines; Chieo Rei, Scliar and Duas Bocas being among the largest deposits. Detailed geologieal mapping of both the Lages-Antônio Dias area (1:2000) and these mines (1:250 se ale) showed that gold is associated with

5. Mecanismos de alojamento de magmas granitóides :exemplo do plúton de Japi(RN)
This dissertation describes the igneous suites of the Japi granitoid pluton, intrusive in the Paleoproterozoic gneiss-migmatite complex of the eastern domain of the Seridó Belt, northeastern Brazil. Field relations show that the pluton is affected by strong deformation associated to the Brasiliano orogeny (known as the D3 phase) , with a NW-trending extensi
