Water-Rock Interactions in the Bauru Aquifer System - Sao Paulo State, Brazil
(Elsevier B.V., 2017-01-01)
The study focuses on the assessment of mineral saturation indexes using data of physicochemical analysis of groundwater samples from different units of the Bauru Aquifer System, in the State of Sao Paulo, Brazil. The ...
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 ...
Modeling rock-water interaction of fractured aquifer in itabuna/BA regionModelagem da Interação Água/Rocha nos Aquíferos Fraturados da Região de Itabuna/BA
(2019-01-01)
This research aimed to investigate the geochemical mechanisms that govern the strong hydrochemical variations in the fractured aquifers of the Itabuna/BA region. Plagioclase and quartz comprise the major mineralogy of ...
Rock-solute reaction mass balance of water flowing within an aquifer system with geochemical stratification
(Elsevier B.V., 2020-12-01)
Aquifers possess distinct mineralogy, diagenetic history, and geochemical constraints, which control the pore water's hydrochemistry. Whenever aquifers exchange groundwater, the incoming groundwater establishes a new ...
Geochemical evaluation of bottled groundwater from crystalline aquifers located in the South and southeast of BrazilAvaliação geoquímica das águas envasadas de aquíferos cristalinos no sul e sudeste do Brasil
(2019-01-01)
The mechanisms related to rock-water interaction are important to understand the quality of groundwater. The chemical composition of 38 brands of bottled water from crystalline aquifers located in the South and Southeast ...

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 ...
Chemical weathering rates of clastic sedimentary rocks from the Paraná Basin in the Paulista Peripheral Depression, Brazil
(2019-12-01)
The chemical weathering plays an important role in the processes of surface geochemistry, which is fundamental to understand the landscape evolution. The Paraná Basin is an intracratonic sedimentary basin developed on the ...
Geo(anthropo)genic factors affecting the radioactivity in groundwaters from Guarani aquifer, Brazil
(2003-12-01)
This investigation was carried out within the Paraná sedimentary basin, involved the sampling of 77 pumped tubular wells, and was realized with the puipose of evaluating the radioactivity in the Brazilian part of Guarani ...
