Proterozoic intracontinental basin succession in the western margin of the São Francisco Craton: Constraints from detrital zircon geochronology

Furthermore, based on the new data, we present a stratigraphic revision for the actual Araí and Paranoá groups, proposing to raise the Traíras Formation to group status and its former members to formation status, representing an individual sag-type basin, different from the Araí rift-type basin. We also propose to combine the three Proterozoic intracontinental extensional pulses (which generated the Araí, Traíras and Paranoá groups) as the Veadeiros Supergroup, respectively chronocorrelated to the lower, middle and upper Espinhaço Supergroup, located at the SFC eastern margin.
