    The sedimentology, stratigraphy and tectonic context of the São Francisco Supergroup at the southwest boundary of the São Francisco Craton, Brazil.
    (2000) Castro, Paulo de Tarso Amorim; Dardenne, Marcel Auguste
    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. The last two units formed in storm influenced muddy shelf and platform/ramp systems, respectively. The psephitic unit crops out as isolated bodies nearby the external zone of the southernmost part of Brasilia Fold and Thrust Belt. Its origin is related to fan delta systems that developed eastward, in a foreland basin, as a result of erosion of metamorphic rocks of Brasilia Fold and Thrust Belt.
