Gravimetric survey and modeling of the basement morphology in the sedimentary thickness characterization, NE portion of Paraná Sedimentary Basin - Brazil
(2017-06-01)
The northeast portion of the Paraná Sedimentary Basin is distinguished by structural highs as the known Pitanga Dome, an uplifted structure identified in the last century. It represents a geological and evolutionary evidence ...
A comparative study of aquifer systems occurring at the Paraná sedimentary basin, Brazil: U-isotopes contribution
(2013-01-01)
The radioactivity due to 238U and 234U in three aquifer systems occurring within the Paraná sedimentary basin, South America, has been investigated. Uranium is much less dissolved from fractured igneous rocks than from the ...
Lower Cretaceous provenance in the northern Austral basin of Patagonia from sedimentary petrography
(Elsevier, 2015-09)
The northern Austral basin from Patagonia is characterized by an Early Cretaceous (Barremian–Albian) coarse-grained regressive sequence. These littoral to continental deposits conform a 150 km long basin cropping out along ...
Rb-Sr systematics applied to sedimentary rocks: the example of Paraná Basin, BrazilO Método Radiométrico Rb-Sr Aplicado em Rochas Sedimentares o Exemplo da Bacia do Paraná, Brasil
(Instituto de Geociências /Universidade Federal do Rio Grande do Sul, 2006)
Grupo itararé (P - C da bacia do Paraná) nas regiões de Limeira e Piracicaba - SP: Contribuição ao estudo das litofácies
(2009-12-01)
The Permian-Carboniferous Itararé Group is one complexe lithostratigraphic unit of the Paraná Basin, southeastern Brazil, typically marked by discontinuity of its lithofacies. Under the exploratory point of view, the unit ...
A comparative study of aquifer systems occurring at the Parana sedimentary basin, Brazil: major hydrochemical trends
(Springer, 2012-12-01)
This investigation was carried out within the Parana sedimentary basin, Brazil, and involved the sampling of 80 pumped tubular wells for evaluating the hydrochemistry in three aquifer systems (Bauru, Serra Geral and Guarani) ...
Late Paleozoic tectono-sedimentary evolution of eastern Chaco-Paraná Basin (Uruguay, Brazil, Argentina and Paraguay)
(2021-03-01)
Recent surface and subsurface information from the Chaco-Paraná Basin in Argentina, Brazil, Paraguay and Uruguay south of the Asunción Rio Grande Arch allowed proposing a regional tectonic-sedimentary evolution for the ...
Geochemistry of siltstones from the Permian Corumbatai Formation from the Parana Basin(State of Sao Paulo, Brazil): Insights of provenance, tectonic and climatic settings
(Elsevier B.V., 2020-10-01)
The Corumbatai Formation is a Permian sedimentary unity comprising siltstones, claystones and very fine sandstones, deposited above calcific shales, bituminous shales and dolomitic limestones from the Irati Formation, ...
Major and trace elements redistribution in weathered claystones from the Corumbatai Formation, Parana Sedimentary Basin, Sao Paulo, Brazil
(Soc Brasileira Geologia, 2017-10-01)
We studied 30 samples from 10 mining fronts of clayish rocks of the Corumbatai Formation, in the region of the Santa Gertrudes Ceramic Pole (Sao Paulo, Brazil), in order to evaluate the variation of rare earth elements ...
Geoelectrical prospection of disseminated sulfide mineral occurrences in Camaquã Sedimentary Basin, Rio Grande do Sul State, Brazil
(2012-12-01)
The mineral exploration is a complex activity that should involve a combination of direct and indirect techniques of geological investigation. The growing demand for base metals in the national and international market ...
