Nova analise da evolução carstica do canion do Rio Peruaçu (Minas Gerais, Brasil). - Nouvelle approche de l’évolution karstique du canyon du rio Peruaçu (Minas Gerais, Brésil).
The River Peruaçu Basin develops on the left margin of the Rio São Francisco, north of the Minas Gerais state. In its lesser course, the river cross through the Bambui limestones, of Proterozoic age, lying over the basement of the São Francisco craton, opening an impressive karst landscape with very deep collapse dolinas over a fluvio-karst drainage. For over 17 km, it develops a large canyon interrupted by great tunnel caves.
