Neoproterozoic glacial deposits from the Aracuai orogen, Brazil: Age, provenance and correlations with the Sao Francisco craton and West Congo belt

, 2012
Glacigenic diamictite successions of the Macaubas Group are widespread in the western domain of the Aracuai orogen, east of the Sao Francisco craton (Brazil). Diamictites also occur on this craton and in the African counterpart of the Aracuai orogen, the

Tectonic implications of precambrian Sm-Nd dates from the southern São Francisco craton and adjcent Araçuaí and Ribeira belts, Brazil.

, 2000
The Archean and Paleoproterozoic São Francisco craton of eastern Brazil is surrounded on all sides by Brasiliano (=Pan African) orogens. The N–NE trending orogen that separates the eastern edge of the southern São Francisco craton from the Atlantic coast

The 2012–2013 Montes Claros earthquake series in the São Francisco\ud Craton, Brazil: new evidence for non-uniform intraplate stresses\ud in mid-plate South America

, 2015
On 2012 May 19, an mb = 4 earthquake shook the town of Montes Claros, Brazil in the\ud middle of the S˜ao Francisco Craton. Because of the scarce seismicity in the area, an event\ud like this could provide valuable information to characterize the ...

The sedimentology, stratigraphy and tectonic context of the São Francisco Supergroup at the southwest boundary of the São Francisco Craton, Brazil.

, 2000
Neoproterozoic metasedimentary rocks of the São Francisco Supergroup occur in the Southwest part of São Francisco Craton. Three informal lithostratigraphic units composed mainly by psephites, pelites and carbonates represent the São Francisco Supergroup.

Reconstruction of Precambrian terranes of Northeastern Brazil along Cambrian strike-slip faults: a new model of geodynamic evolution and gold metallogeny in the State of Bahia

Brazilian Journal of Geology, 2019
The Precambrian basement of Northeastern Brazil is the product of Rhyacian block convergence. The main deformation and intrusion of crustal granitoids occurred between 2.15 and 1.8 Ga ago.
