UPb geochronology of the central Ribeira belt (Brazil) and implications for the evolution of the Brazilian Orogeny
TL;DR: The Ribeira belt in southeastern Brazil was generated during the Brazilian Orogeny (∼ 700-450 Ma) as discussed by the authors, which is characterized by a series of northwest-vergent crustal-scale thrust stacks emplaced under amphibolite-grade conditions.
Journal ArticleDOI
U-Pb geochronology of the southern Brasília belt (SE-Brazil): Sedimentary provenance, Neoproterozoic orogeny and assembly of West Gondwana
Claudio de Morisson Valeriano,Nuno Machado,Antonio Simonetti,Claudia Sayão Valladares,Hildor José Seer,Luiz Sérgio Amarante Simões +5 more
TL;DR: In this paper, the authors reported new U-Pb data from the southern sector of the Brasilia belt in order to provide temporal limits for the deposition and ages of provenance of sediments accumulated in passive margin successions around the south and southwestern margins of the Sao Francisco Craton, and date the orogenic events leading to the amalgamation of West Gondwana.
Journal ArticleDOI
A orogênese brasiliana no segmento central da faixa ribeira, brasil
TL;DR: The structure of the Ribeira belt is defined by three large thrust sheets (Lower, Intermediate and Upper) which override the autochthonous domain, towards the southern portion of the Sao Francisco Craton as mentioned in this paper.
Journal ArticleDOI
Ages of Detrital Zircon from Siliciclastic Successions South of the São Francisco Craton, Brazil: Implications for the Evolution of Proterozoic Basins
TL;DR: In this paper, the ages of 152 detrital zircons from lower greenschist facies quartzites from Proterozoic basin successions of the southern border of the Sao Francisco Craton, southern Minas Gerais State, Brazil were reported.
