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. Razões isotópicas 87Rb/86Sr, 87Sr/86Sr e 143Nd/144Nd como traçadores de proveniência de rochas sedimentares siliclásticas: exemplos no Grupo Camaquã(Paleozóico interior; RS, Brasil)
The Rb-Sr and Sm-Nd isotopic systems are ideal in constraining the provenance of fine-grained clastic rocks. This is particularly true for continental, fluvio-lacustrine, sedimentary units deposited under semi-arid climate conditions, where mechanical desintegration of source rocks dominates the weathering processes. Three sets of red-colored, continental si

4. 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

5. Monumento Natural das FalÃsias de Beberibe/Ce: diretrizes para o planejamento e gestÃo ambiental / Cliffs Natural Monument of Beberibe / Ce: guidelines for planning and environmental management
The coast of Beberibe is known by its landscape diversity, mainly because of the cliffs with colored sands which form structures, such as the maze and MÃe DâÃgua Cave. The cliffs landscape, which is from Morro Branco Beach to the beginning of Fontes Beach, was decreed a Conservation Unit, the Natural Monument of Beberibe Cliffs, a category which integrate

6. VIANENSE LACUSTRINE SYSTEM: ESSAY OF CONCEPTUAL MODELS FOR THE LAKES IN VIANA IN MARANHÃO. / SISTEMA LACUSTRE VIANENSE: ENSAIOS DE MODELOS CONCEITUAIS PARA OS LAGOS DO MUNICÍPIO DE VIANA-MA
VIANENSE LACUSTRINE SYSTEM: ESSAY OF CONCEPTUAL MODELS FOR THE LAKES IN VIANA IN MARANHÃO. We consider a study about the functional aspects of the lacustrine set of Viana in Maranhão in which it is focused the dynamic and structural work and also the dynamical and structural elements of the enviroment. Highlighting the hydroclimatic factors which are respo

7. Paisagem natural paleógena da bacia sedimentar de São Paulo no município de Guarulhos, Estado de São Paulo.
Sedimentary rocks of Cenozoic age, composed primarily of sand and clays, can be found in the city of Guarulhos, located in the metropolitan area of the city of São Paulo, State of São Paulo, Brazil. Paleogene sediments of this region represent a significant source of water for urban, industrial and agricultural activities. This basin is an integral part of

8. COMUNIDADE ZOOPLANCTÔNICA DE CINCO RESERVATÓRIOS TROPICAIS DO SISTEMA FURNAS S.A. (BRASIL): ABUNDÂNCIA E BIOMASSA EM CARBONO / COMUNIDADE ZOOPLANCTÔNICA DE CINCO RESERVATÓRIOS TROPICAIS DO SISTEMA FURNAS S.A. (BRASIL): ABUNDÂNCIA E BIOMASSA EM CARBONO
Gases generation, as contributor to the greenhouse, inside reservoirs it is one of the possible impacts caused for these systems to environment. Inside reservoirs, the zooplankton community had constituted one source of carbon so that this community would be also under influence of other physical, chemical and biological factors associated with morphometric

9. SUSTENTABILIDADE DOS SISTEMAS AGRO-EXTRATIVOS DE PRODUÇÃO DA REGIÃO LACUSTRE DE PENALVA-MA, NA ÁREA DE PROTEÇÃO AMBIENTAL DA BAIXADA MARANHENSE / The sustainability of agro-Extractive systems in the lacustrine region of Penalva, in the Area of Environmental Protection of Baixada Maranhense
The lacustrine region of Penalva, in the Area of Environmental Protection of Baixada Maranhense, has a number of agro-extractive systems which are characteristics of the traditional human populations of this region. These systems are distributed on different landscape units of the municipal district, and composed by different agricultural, fishing, extractiv

10. Aplicação de sensoriamento remoto no estudo da influência da dinâmica sazonal do Rio Amazonas sobre a morfologia dos sistemas lacustres / Use of remote sensing to study Amazon river seasonal dynamic on floodplain lake system morphology
Nesta pesquisa foi avaliado o efeito da dinâmica sazonal do nível d´água do rio Amazonas, sobre a caracterização morfológica dos sistemas lacustres. A área de estudo selecionada para esta pesquisa compreende a faixa da planície de inundação do Rio Amazonas, que se estende do rio Madeira, ao rio Tapajós. O presente trabalho teve como hipótese que

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

12. Phylogeography and RAPD-PCR variation in Hoplias malabaricus (Bloch, 1794) (Pisces, Teleostei) in southeastern Brazil
In the Rio Doce basin of southeastern Brazil, the freshwater fish Hoplias malabaricus (trahira) is a widespread predatory characin and one of the few resilient native fishes in a highly impacted lake system. In order to test for genetic differentiation in populations within this basin and for biogeographic relationships among populations of this species in o
