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 ...
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) ...

U-ages in soils and groundwater evidencing wet periods 400-600 kyr ago in southeast Brazil
(Elsevier B.V., 2007-07-01)
U-238 and its radiogenic daughter U-234 have been utilized for dating soil formation and groundwater residence time during the last 1.5 million years, in this case based on the U-clissolution/precipitation occurring during ...

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 ...
