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 ...
Indicadores cinemáticos deformacionais do granito itapeti, Região de mogi das cruzes-sp
(2014-01-01)
Itapeti granitic body is located near the cities of Mogi d as Cruzes, Guararema and Santa Branca-SP. It is inserted in Precambrian metamorphic rocks with a large extent inlaid in the Taxaquara Shear Zone. Foliations, ...
Sm-Nd system in total rock open versus closed isotopic composition in zones of high deformation
(2002-12-01)
High strain shear zones of Brasiliano age, developed in Paleoproterozoic basement gneiss of the Caicó region, Borborema Province, NE Brazil, were associated with medium- to low-grade metamorphism and deformational processes ...
Early foreland deformation of the Fuegian Andes (Argentina): Constraints from the strain analysis of Upper Cretaceous-Danian sedimentary rocks
(Elsevier, 2013-01)
This contribution addresses new structural data from Upper Cretaceous-Danian sedimentary rocks of the Fuegian Andes orogenic front in Argentina. The structures studied, called D0 , were formed during the early foreland ...
