The basement of the South American platform displays the lithostructural and tectonic records of three major orogenic collages: Middle Paleoproterozoic (or Transamazonian), Late Mesoproterozoic/Early Neoproterozoic and Late Neoproterozoic/Cambrian, the Brasiliano-Pan African collage. The first two collages have their records in the basement of the Syn-Brasiliano cratons and Brasiliano Fold Belts.
