The Devonian Durazno Group as part of the Paraná Basin was deposited in an extensional basin.
- class="label">•
Its provenance is determined by petrography, geochemistry and detrital zircon dating.
- class="label">•
U–Pb detrital zircon age populations indicate main sources related to the Neoproterozoic, whereas minor record Mesoproterozoic rocks.
- class="label">•
Provenance from the Cuchilla Dionisio-Dom Feliciano, Nico Pérez and Piedra Alta terranes (Uruguay-Brazil) is evident.
- class="label">•
Source rocks and paleogeographical implications in SW Gondwana are compared and discussed.
