The Hesperides basin: a continental-scale upper Palaeozoic to Triassic basin in southern Gondwana
(Wiley Blackwell Publishing, Inc, 2016-10)
The late Palaeozoic to Triassic sedimentary record of the central Argentinean offshore was analysed through the integration of data from exploratory wells and 2D seismic lines. Our interpretations were combined with existing ...
Integration of sedimentological and ichnological analysis on the wave-dominated deposits of The Maastrichtian Calafate Formation, Austral-Magallanes Basin, Argentina
(Elsevier, 2020-11)
An integrated study combining sedimentological and ichnological data has been conducted in the lower wave-dominated deposits of the Calafate Formation. The study aimed to assess the variation in fair-weather and storm ...
Recognizing drainage reorganization in the stratigraphic record of the Neogene foreland basin of the Central Andes
(Elsevier Science, 2020-07)
Changes in drainage basin reorganization as preserved in the stratigraphic record have direct implications for the composition, organization, and scaling relationships of sedimentary systems. However, isolating the ...
U–Pb detrital zircon ages in the Lajas Formation at Portada Covunco: Maximum depositional age and provenance implications for the Neuquén Basin, Argentina
(Pergamon-Elsevier Science Ltd, 2021-10)
The Lajas Formation of the Neuquén Basin (Argentina) was deposited mainly during the Middle Jurassic but with a highly diachronic pattern. The exact time elapsed in the deposition of this unit remains controversial and ...
The Iglesia basin in the southern Central Andes: A record of backarc extension before wedge-top deposition in a foreland basin
(Elsevier Science, 2020-10)
The Iglesia basin hosts a key sedimentary archive of the evolution of the southern Central Andes. This basin is classically interpreted as recording the transition from an outer- to an inner-wedge-top (piggyback basin) ...
Sedimentary evolution and tectonic setting of the Itapucumi Group, Ediacaran, northern Paraguay: From Rodinia break-up to West Gondwana amalgamation
(Elsevier Science, 2019-03)
The Itapucumi Group is recognized worldwide due to its well-preserved Ediacaran fossil assemblage. Despite its paleontological importance, this unit remains as the least studied South American Neoproterozoic sedimentary ...
Glacial-related morphology and sedimentary setting of a high-latitude lacustrine basin: The Lago Chepelmut (Tierra del Fuego, Argentina)
(Pergamon-Elsevier Science Ltd, 2018-10)
Lago Chepelmut is a relatively small lake in size, of ellipsoidal shape, located in the outer fold-and-thrust belt of the Fuegian Andes (southernmost South America). High-resolution single-channel seismic profiles, integrated ...
Flexural isostasy in the Bolivian Andes: Chaco foreland basin development
(Elsevier Science, 2009-09)
The Chaco foreland basin was initiated during the late Oligocene as a result of thrusting in the Eastern Cordillera in response to Nazca-South America plate convergence. Foreland basins are the result of the flexural ...
The Huncal Member of the Vaca Muerta Formation, Neuquén Basin of Argentina: Insight into biostratigraphy, structure, U-Pb detrital zircon ages and provenance
(Pergamon-Elsevier Science Ltd, 2020-06)
In the western sector of the Neuquén Basin, the organic-rich shales of the Vaca Muerta Formation are intercalated with turbidite sandstone intervals and slump structures integrated in the Huncal Member. The age of the ...
Late Paleozoic tectono-sedimentary evolution of eastern Chaco-Parana Basin (Uruguay, Brazil, Argentina and Paraguay)
(Pergamon-Elsevier Science Ltd, 2020-11-04)
Recent surface and subsurface information from the Chaco-Paraná Basin in Argentina, Brazil, Paraguay and Uruguay south of the Asunción Rio Grande Arch allowed proposing a regional tectonic-sedimentary evolution for the ...
