Upper crustal differentiation processes and their role in 238U-230Th disequilibria at the San Pedro-Linzor volcanic chain (Central Andes)
(PERGAMON-ELSEVIER SCIENCE LTD, 2020)
Upper crustal differentiation processes and their role in 238U-230Th disequilibria at the San Pedro-Linzor volcanic chain (Central Andes)
(Elsevier, 2020)
U-series data are combined with major and trace element constraints to construct a detailed view of the magmatic system feeding the San Pedro-Linzor volcanic chain, aiding the understanding of how stratovolcanoes in extremely ...

O dólar e os desequilíbrios globaisThe dollar and the global disequilibria
(Editora 34, 2005)
Mantle heterogeneity controls on small-volume basaltic volcanism
(Geological Soc Amer, 2015)
Eruptions of basaltic material in small-scale volcanic fields located in intraplate settings display a very diverse range in physical and chemical characteristics. Despite its relevance to the understanding of volcanic ...
Uranium series disequilibria in ground waters from a fractured bedrock aquifer (Morungaba Granitoids-Southern Brazil): Implications to the hydrochemical behavior of dissolved U and Ra
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Activity concentrations of dissolved U-234, U-238, Ra-226 and Ra-228 were determined in ground waters fromtwo deep wells drilled in Morungaba Granitoids (Southern Brazil). Sampling was done monthly for little longer than ...
Weathering processes and dating of soil profiles from São Paulo State, Brazil, by U-isotopes disequilibria
(2017-01-01)
This study reports the use of the U-series radionuclides 238U and 234U for dating two soil profiles. The soil horizons developed over sandstones from Tatuí and Pirambóia formations at the Paraná sedimentary basin, São Paulo ...
The assessment of soils contamination from U-238 and U-234 disequilibria data
(2018-01-01)
Understanding processes involved in the soils formation is important for appropriate assessment of contamination occurring in the superficial horizons. Several tools have been used for such purpose, including the natural ...
