Eocene volcanism in the Fuegian Andes: Evidence from petrography and detrital zircons in marine volcaniclastic sandstones
(Pergamon-Elsevier Science Ltd, 2020-12)
The sedimentology, petrography, and U–Pb dating of two Eocene volcaniclastic horizons of the Punta Torcida and Leticia formations, Austral basin, Tierra del Fuego, Argentina are interpreted and documented. The volcaniclastic ...

Calibrating the Ediacaran-Cambrian transition in the SW Gondwana
(Consejo Superior Investigaciones Cientificas-csic, 2019-01-01)
The paleontological, isotopic and geochronological data summarized below support the paleogeographic and temporal correlation between Itapucumi (Paraguay) and Corumba (Brazil) groups, suggesting a coeval sedimentary evolution ...

Detrital zircons from late Paleozoic accretionary complexes in north-central Chile (28°-32°S): Possible fingerprints of the Chilenia terrane
(Pergamon-Elsevier Science Ltd, 2011-05)
During the Paleozoic the Andean basement of central Chile and Argentina grew westwards by the amalgamation of diverse tectonostratigraphic terranes some of them derived from Laurentia. The last to be accreted, in the ...
Petrography and detrital zircon U-Pb geochronology of sedimentary rocks of the Campo Alegre Basin, Southern Brazil: implications for Gondwana assembly
(Sociedade Brasileira de Geologia, 2019)
Detrital zircon geochronology and provenance of the Chubut Group in the northeast of Patagonia, Argentina
(Elsevier, 2015-11)
The Chubut Group constitutes the most widespread sedimentary unit in NE Patagonia, characterized by variable-energy fluvial deposits. U–Pb analysis of detrital zircons from two sections of the Chubut Group constraint the ...
Evolution of exhumationand erosion in western west gondwanaland as recorded by detrital zircons of late Neoproterozoic and Cambrian sedimentary rocks of NW and Centraal Argentina.
(Springer-Verlag, 2011-06)
The evolution of the provenance areas for Late Neoproterozoic,Cambrian and Early Ordovician sedimentary and meta-sedimentaryrocks of north central and northwest Argentina is discussed using 123maximum ages of detrital ...
Geochemistry of heavy minerals and U-Pb detrital zircon geochronology in the manantiales basin: implications for Frontal Cordillera uplift and foreland basin connectivity in the Andes of central Argentina
(Elsevier, 2018)
The Manantiales Foreland Basin, located at similar to 32 degrees 15'S in the Frontal Cordillera, Argentina, contains the sedimentary record of erosion of igneous basement and Miocene volcanic rocks exhumed during the Andean ...
U-Pb zircon ages from the northern Austral basin and their correlation with the Early Cretaceous exhumation and volcanism of Patagonia
(Academic Press Ltd - Elsevier Science Ltd, 2015-07)
The end of the Early Cretaceous sag stage along the Southern Patagonian Andes is indicated by the sudden appearance of shallow marine to deltaic sandstones on top of deep marine facies. We studied the detrital and volcanic ...
