Geotechnical properties of Brazilian weak sedimentary rocks
(2014-01-01)
The sedimentary rocks cover about 70% of the Brazilian territory. Large sedimentary basins, from the Paleozoic to the early Cenozoic, present a wide variability of lithology, raging from coarse grained rocks as 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 ...
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)
Neogene erosion of the Andean Cordillera in the flat-slab segment as indicated by petrography and whole-rock geochemistry from the Manantiales Foreland Basin (32°–32°30′S)
(Elsevier, 2015)
The Miocene Manantiales Foreland Basin is defined as a thick succession of sedimentary rocks belonging to the Chinches Formation in the Frontal Cordillera between 32 degrees S and 32 degrees 30 degrees S, located over the ...
Geochemical aspects of the silicification in sedimentary rocks in Rio Grande do Sul, BrazilAspectos Geoquímicos de Silicificações em Rochas Sedimentares no Rio Grande do Sul, Brasil

Reactivity of Sedimentary and Metamorphic Limestones of Different Particle Sizes under Controlled Conditions
(2019-02-21)
The efficiency of limestone in amending soil acidity is primarily based on the particle size and the neutralization value of the ground rock, but the origin of the rock can also affect its reactivity. The aim of this work ...
