25. A interação entre os eventos tectônicos e a evolução geomorfológica da Serra da Bocaina, Sudeste do Brasil / The interaction between tectonic events and the landscape evolution of Bocaina Ridge, Southeastern Brazil
The Bocaina Ridge landscape is strongly controlled by both ductile and brittle structures related to the Ribeira Belt (Brasiliano Orogeny ca. 790-480Ma) and also to the mesozoic-cenozoic reactivations. The rocks were subdivided in four tectonic terrains accreted in the brasiliano collisional stages. The most prominent structures related to these collisions a

26. Considerações morfo-estruturais ao largo da Ponta do Pai Vitório, Búzios, RJ / Morfo-structural considerations offshore of Ponta do Pai Vitório, Búzios, RJ
The understanding of the mechanisms e causes of the tectonic movements has much worried the human race, not only in concern of natural catastrophic events, as well as the protection and maintenance of engineering structures and bottom and sub-bottom morphology in many places of the earths crust. This present work aims to illustrate structural features origin

27. "Tectônica rúptil mesozóico-cenozóica na região da Serra dos Órgãos, RJ" / "Mesozoic-Cenozoic brittle tectonics of the Serra dos Órgãos range, RJ"
Mezosoic-Cenozoic brittle tectonics of the Serra dos Órgãos range in the Rio de Janeiro State, southeastern Brazil, was investigated using morphostructural analysis and field surveys. The study area is a sector of the Serra do Mar coastal range, with summits over 2.200 m a.s.l., and is included in the central segment of the Neoproterozoic-Cambrian Ribeira

28. Integração de dados de geofísica aérea aplicada à geologia e à prospecção mineral no distrito esmeraldífero de Itabira-Ferros, Quadrilátero Ferrífero, MG.
The Itabira-Ferros area is located in the Quadrilátero Ferrifero region, State of Minas Gerais, and it is known for abundant emerald occurrences. The area is characterized by volcanic metasedimetary sequences of the greenstone belt type (Rio das Velhas Super group) and paleoproterozoic iron formations of Minas Super Group, inserted in granitic bobies (Borra

29. Geology and metallogenetic potential of the anorthositic-leucogabbroic Lagoa da Vaca Complex, Curaça, Bahia State, Brazil / Geologia e potencial metalogenetico do complexo anortositico-leucogabroico de Lagoa da Vaca, municipio de Curaça, Bahia
The complex is one of the three litho-structural domains mapped (central domain), and has an outcrop width of 3 kilometers. It is made up mostly of north-south-trending layers of anorthositic, meta-leucogabbroic, meta-gabbroic and ultramafic compositions. Ultramafic rocks of unknown stratigraphic relations, vz. peridotite and amphibole meta-peridotite, were

30. A edificação urbana como expressão da prática informacional: análise do campo tectônico de Belo Horizonte
The thesis views the urban building as a product of the art of edifying, engaged in its cultural and social dimensions. We are interested in recognizing the information concerning urban building as part of the field of knowledge and in understanding the social relations between the subjects all of them as elements to investigate information as a social pract

31. Tectonic evolution of the Maranco-Poço Redondo Domain : records of the Cariris Velhos and Brasiliano orogenesis on the Sergipano belt, NE Brazil / Evolução tectonica do dominio Maranco-Poço Redondo : registro das orogeneses Cariris Velhos e Brasiliana na Faixa Sergipana, NE do Brasil
This Thesis aims to advance in the geological knowledge of the Sergipano Belt, by studying the tectonic evolution for two within seven lithotectonic domains: the Marancó -Poço Redondo Domain. To reach the objective a detailed field work, that used four geological maps (1:100.000) from the Carira Project (PLGB, DNPM-CPRM, 1988) as base maps and a Landsat im

32. Caracterização macro, meso e microscópica das estruturas frágeis do corpo arenítico conglomerático da região de Santana do Acaraú (CE) e seu embasamento circundante
The structural framework of the sedimentary basins usually plays an important role in oil prospects and reservoirs. Geometry, interconectivity and density of the brittle features developed during basin evolution could change the permo-porous character of the rocks involved in generation, migration and entrapment of fluid flow. Once the structural characteriz

33. Evolução tectono-estrutural do Campo de Xaréu (Sub-bacia de Mundaú, Bacia do Ceará - NE do Brasil: abordagem multiescala e pluriferramental
The Xaréu Oil Field, located in the center-southern portion of the Mundaú Sub-Basin (eastern portion of the Ceará Basin), is characterized by a main Iramework of NW-trending and NE-dipping faults. The faults in the Xaréu Oil Field, among which the Xaréu Fautt stands out, are arranged according to an extensional-listriclan, rooted on a detachment surface

34. Estratigrafia fÃsica e deformaÃÃo do sistema lacustre carbonÃtico (aptiano-albiano) da bacia do Araripe em afloramentos selecionados / Physical Estratigrafia and deformation of the carbonÃtico lacustrine system (aptiano-albiano) of the basin of the Araripe in selected outcrops
The purpose of this thesis was to study the physical stratigraphy of the carbonate deposits exposed in the Araripe Basin, in order to help in the quality prediction of the subsurface analogous reservoirs. The following methods were applied: field work for the selection of outcrops, and consecutive stratigraphical and sedimentological descriptions, sample col

35. 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

36. Petrogenese das intrusões graniticas compostas de Teofilandia e Barrocas, Greenstone Belt do Rio Itapicuru, Bahia, Brasil
The Rio Itapicuru Greenstone Belt (RIGB) is a Paleoproteozoic sequence situated in the northern portion of the São Francisco Craton, Bahia state, Brazil. Overlying a basement consisting of gnaisse and migmatites, this volcanic-sedimentary belt is intruded by several granitoid intrusions of different chemical compositions. Two of the most important intrusive
