“…The new U-Pb ages and Hf isotopic compositions reveal that the detrital zircons of the Rio do Rasto Formation have similar frequency peaks those obtained by Ramos et al (2013) for several units in the Paleozoic Ventania Fold Belt and Claromec o Basin of central-eastern Argentina, the Silurian-Devonian successions of the southern Paran a Basin in central-northern Uruguay (Uriz et al, 2016) and Argentinean North Patagonian Massif (Pankhurst et al, 2006;Uriz et al, 2011). These data associated with large number of alluvial paleocurrent measures indicate a consistent sedimentrouting system from the south to north, with source areas located to the south and southeast of the Paran a Basin depositional site.…”

“…462 and 475 Ma found in the Rio do Rasto Formation can be chronocorrelated with the frequency peaks of 469 Ma found in the pre-Carboniferous rocks of the Cape Fold Belt (South Africa) (Fourie et al, 2011), the 478 Ma peak in the Balcarce Formation (Tandilia System) (Rapela et al, 2011) and the 475 Ma peak obtained for the Lol en Formation in the Ventania System, Argentina (Ramos et al, 2013). Recent U-Pb detrital zircon ages from the Devonian Durazno Group (Cerrezuelo and La Paloma formations) in the southern Paran a Basin of Uruguay (Uriz et al, 2016), indicating that the main source areas are Neoproterozoic, with minor contributions derived from Mesoproterozoic and Archean-Paleoproterozoic rocks. It is important to note that the youngest detrital zircons of the Durazno Group are Ordovician-age, defining a maximum sedimentation age of 485 and 484 Ma for the Cerrezuelo and La Paloma formations, respectively (Uriz et al, 2016).…”

The Late Permian sedimentary succession of the Paran a Basin, southern Brazil, provide a valuable source of information about sediment provenance, tectonic processes and, consequently, the paleogeography of the southwestern Gondwana supercontinent. In order to understand the patterns of sedimentary dispersal and reconstruct the Late Permian source-to-sink dynamic, we report a complete series of U-Pb ages and Hf isotopic compositions of detrital zircons from the Rio do Rasto Formation sandstones allied with detailed paleocurrent and sedimentologic data. Our integrated provenance study reveals a consistent sediment transport from the south to the north and northwest. According to the evaluation of zircon ages and Hf isotopes, it was possible to determine four distinct source areas: (i) a distant Late Paleozoic active magmatic arc located in the southwestern Gondwana margin (i.e. Gondwanides Orogen), corresponding to the North Patagonian Massif; (ii) recycling of orthoquartzites from the uplifted Paleozoic Ventania Fold Belt and immature sandstones from the Claromec o Foreland Basin in centraleastern Argentina and the Silurian-Devonian successions of the southern Paran a Basin (central-northern Uruguay) and North Patagonian Massif; (iii) exhumed areas of the Archean-Paleoproterozoic basement and Neoproterozoic to Early Paleozoic mobile belts of the Damara in southwestern Africa and Ribeira Fold Belt in Uruguay and southern Brazil; and (iv) southeastward provenance of Grenvillian (1.2 e1.0 Ga) zircons coming from the mafic to intermediate Mesoproterozoic igneous units of the Namaqua-Natal Belt in South Africa and Namibia. These data allow us to argue that sediments deposited in the Paran a Basin during the Late Permian come from both short-and long-distance source areas. In this context, an important population of Permian detrital zircons comes from the Gondwanides Orogen in the south, probably carried by transcontinental alluvial systems. Close to the source area, antecedent river channels would have eroded older sedimentary rocks of the Ventania Fold Belt, Claromec o and Chaco-Paran a basins and North Patagonian Massif, crosscutting a peripheral bulge and flowing towards the alluvial plain of the intraplate setting to areas further north. Concomitantly, these sediments are reworked by strong winds that even helped carrying the grains to the Paran a Basin depositional site.

“…The increasing number of studies combining paleocurrents and U-Pb-Hf data from detrital zircons has significantly improve our understanding of the Paleozoic paleogeographical scenario of the Paran a Basin and adjacent areas of southwestern Gondwana (see Ramos et al, 2013;Alessandretti et al, 2016;Andersen et al, 2016;Canile, 2016;Canile et al, 2016;Uriz et al, 2016). Here, again, we will scrutinize the paleogeographic configuration of the southwestern Gondwana and emphasize the problematic involving the sources of the sediments during the end of Permian.…”

“…The paleogeography of the SW Gondwana has been intensely debated for over a century, since the precursor works of Keidel (1913Keidel ( , 1916 and Du Toit (1927,1937). More recently, significant contributions provided a range of new data on the tectonic evolution of the southwestern sector of Gondwana, shedding light on some key questions on this issue (Newton et al, 2006;Tankard et al, 2009;Ramos et al, 2013;Linol et al, 2015;P angaro et al, 2015;Andersen et al, 2016;Alessandretti et al, 2016;Canile et al, 2016;Uriz et al, 2016). Ramos et al (2013) reported a detailed provenance study of the Paleozoic Ventania System of central-eastern Argentina, reinforcing the proposition of the Late Paleozoic collision of Patagonia terrane against the southern Gondwana continental margin.…”
