Evidence of Siderian juvenile-like contribution to the continental arc magmatism in the Western Guanambi-Correntina block, São Francisco Craton (Brazil).

The Guanambi-Correntina Block, a basement relic within the Sao ̃ Francisco Craton, played a determining role in the stabilization of the South American plate during the Paleoproterozoic, preceding the formation of the Nuna-Columbia supercontinent ...

Neoproterozoic glacial dynamics revealed by provenance of diamictites of the Bebedouro Formation, Sao Francisco Craton, Central Eastern Brazil

, 2009
One of the main questions on Neoproterozoic geology regards the extent and dynamics of the glacial systems that are recorded in all continents. We present evidence for short transport distances and localized sediment sources for the Bebedouro Formation ...

Transamazonian orogeny in the Southern São Francisco craton region, Minas Gerais, Brazil : evidence for paleoproterozoic collision and collapse in the Quadrilátero Ferrı́fero.

, 1998
The Paleoproterozoic Transamazonian orogeny yielded a series of discrete orogens in Brazil. The present field study in the Quadrilátero Ferrı́fero (QF) indicates that the southern São Francisco craton region of the Brazilian highlands preserves a portion

Geophysical perspective on the structural interference zone along the Neoproterozoic Brasília and Ribeira fold belts in West Gondwana

Brazilian Journal of Geology
: The Brasília and Ribeira fold belts have been established in south-southwestern São Francisco Craton during the Brasiliano-Pan African orogeny (0.9-0.5 Ga - Tonian to Cambrian), and played an important role in West Gondwana continent assembly.
