1. Sedimentary and U-Pb detrital zircons provenance of the Paleoproterozoic Piracicaba and Sabará groups, Quadrilátero Ferrífero, Southern São Francisco craton, Brazil
Abstract The Quadrilátero Ferrífero is an important mineral province located in Southern São Francisco craton, SE Brazil. Its prominent feature is the Gandarela syncline that was formed as part of the regional deformation event in the southernmost part of the craton at ca. 2,000 Ma. The syncline exposes several economically important units of Rio das Velh

2. Local geological sections and regional stratigraphy based on physical geology and chemical stratigraphy of the Serra Geral Group from Araraquara to Avaré, SP
ABSTRACT: From Araraquara to Avaré, in the Serra Geral Group outcropping area, 22 detailed geological sections were elaborated. The stratigraphic relationships and the chemical analysis allowed the identification of seven [P2O5] basalt classes, all of them pertaining to the Pitanga type, showing a consistent stacking order across the studied region. Thus, e

3. Sedimentology and stratigraphy of Neoproterozoic-lower Paleozoic carbonate-siliciclastic succession of the southwesternmost Amazon Craton, state of Rondônia, Brazil
ABSTRACT: Facies and stratigraphic analysis were carried out in Neoproterozoic-Lower Paleozoic carbonate-siliciclastic deposits of Cacoal and Pimenta Bueno formations exposed on basement rocks and into the Pimenta Bueno Graben, northwestern portion of Parecis Basin, southwesternmost Amazon Craton. The redescription and redefinion of this succession confirmed

4. Estudios arqueofaunísticos en un contexto estratigráfico de las llanuras interiores de Entre Ríos: el sitio Laguna del Negro 1 (departamento Gualeguay, Argentina)
Abstract The virtual absence of zooarchaeological data from the extensive inland plains of Entre Ríos, northeastern Argentina, can be explained by the scarcity of archaeological investigations and the lack of stratigraphic contexts available for study. Recently, the detection and excavation of Laguna del Negro 1, a late Holocene site with evidence of multip

5. How the use of stratigraphic coordinates improves grade estimation
Abstract Some mineral deposits show mineralization along layers. These layers may pass through several subsequent geological events such as folding and/or severe erosional processes. Grades within these deposits tend to be correlated along orientations where the mineralization was originally deposited or along the same geological period (stratigraphic level)

6. Análise estratigráfica: uma contribuição ao projeto de restauro / Stratigraphic analysis a contribution to the restoration project
O monumento histórico normalmente constitui-se por acúmulos de estratos, mudanças advindas de novas construções ou demolições que se sucedem no tempo e deixam marcas e testemunhos materiais. E é como tal que, do ponto de vista da ciência, cultura e ética, deverá ser compreendido. Isso faz com que seja imprescindível o domínio da estratigrafia pe

7. Análise estratigráfica do campo de Pirapema na bacia da foz do Amazonas / Stratigraphic analysis of Pirapema field at the mouth of the Amazonas basin
A Bacia da Foz do Amazonas localiza-se no extremo noroeste da plataforma continental brasileira, mais precisamente na margem equatorial. Esta margem se distingue da margem leste brasileira, principalmente pela existência de esforços transtensivos que culminaram com a criação de falhas transformantes de direção E-W e, consequente, criação de bacias do

8. 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

9. Mamíferos del pleistoceno superior de santiago del estero (Argentina) y sus afinidades paleobiogeográficas
A new mammalian assemblage from the Upper Pleistocene of the Dique "Los Quiroga" locality (Santiago del Estero province, Argentina), positioned in the Chaco Region is here described. The material here described were collected from fine sand and shale deposits of an unnominated stratigraphic unit. Panochthus greslebini and Mixotoxodon larensis, are described

10. Arquitetura estratigráfica e arcabouço estrutural dos depósitos fluviais albianos da base da Formação São Mateus no Norte da Bacia do Espírito Santo
The main aim of this dissertation is make at the high-resolution stratigraphic subdivision of the basal section from the São Mateus Formation, Albian the Espírito Santo Basin. The interval studied is consists predominantly of alluvial deposits. Against the difficulties presented for the stratigraphic correlation of these deposits, as discussed by Wright &M

11. 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

12. 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
