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 ...
Well productivity controlling factors in crystalline terrains of southeastern Brazil
(Springer, 2007-05-01)
Over the last decades, increasing water demands have fostered research to obtain high well yields in crystalline terrains where, besides the intrinsic properties of rocks, the groundwater flow depends on several factors. ...

Crystalline rock outcrops in the Atlantic Forest of northeastern Brazil: Vascular flora, biological spectrum, and invasive species
(2013-06-01)
We studied the vegetation of two crystalline rock outcrops in the Atlantic Forest of northeastern Brazil. We recorded typically rupicolous species, which are rare or classified as extremely endangered, such as Aechmea ...

Basalt weathering as the key to understand the past human use of hematite-based pigments in southernmost Patagonia
(Pergamon-Elsevier Science Ltd, 2019-12)
The present work aims at understanding the composition and source of the red rock art pigments used by hunter-gatherer groups during the late Holocene in southern Patagonia (southernmost South America), by combining micro ...
Thermo-mechanical behavior of a granodiorite from the Liquine fractured geothermal system (39 degrees S) in the Southern Volcanic Zone of the Andes
(Elsevier, 2020)
Fractures and faults in granitic rocks play an important role in geothermal systems because they permit the circulation of hot fluids. However, the thermo-hydro-mechanical behavior of granitic rocks has predominantly been ...
