Palaeomohria Spores from the Cenomanian in Patagonia, Argentina
(Asociación Paleontológica Argentina, 2021-07)
We report the first Cenomanian record of Palaeomohria in southern South America. This finding comes from the Mata Amarilla Formation, with outcrops in the Austral-Magallanes Basin, Santa Cruz Province. These spores are ...
Sedimentology of the shallow marine deposits of the Calafate Formation during the Maastrichtian transgression at Lago Argentino, Austral-Magallanes basin, Argentina
(Asociación Argentina de Sedimentología, 2018-12)
The Maastrichtian shallow marine deposits exposed at the south margin of the Lago Argentino within the Austral-Magallanes Basin are known as the Calafate Formation. In order to interpret the depositional systems and ...
Sedimentology and stratigraphy of the Puesto El Moro Formation, Patagonia, Argentina: Implications for upper cretaceous paleogeographic reconstruction and compartmentalization of the Austral-Magallanes Basin
(Pergamon-Elsevier Science Ltd, 2019-06)
During the Late Cretaceous, the Austral-Magallanes Basin (AMB) records the change from a thermal subsidence post-rift stage to a retroarc foreland basin scenario. The lower-Upper Cretaceous Puesto El Moro Formation (PMF) ...
The Austral-Magallanes Basin (Southern Patagonia): A synthesis of its stratigraphy and evolution
(Asociación Argentina de Sedimentología, 2019-12)
The Austral-Magallanes is an oil-producing basin located in southern Argentina and Chile, containing a siliciclastic stratigraphic record ranging from the Late Jurassic to Late Cenozoic. This short paper finalize the two ...
Sedimentology and fluvial styles of the uppermost Cretaceous continental deposits of the Austral-Magallanes Basin, Patagonia, Argentina
(Asociación Argentina de Sedimentología, 2018-12)
The sedimentary infill of the Austral-Magallanes Basin since the onset of its foreland stage in the Lago Argentino region is dominated by deep-marine and coastal deposits. However, during the Late Cretaceous the basin ...
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 ...
Tectonic controls on the Maastrichtian-Danian transgression in the Magallanes-austral foreland basin (Chile): implications for the growth of the southern patagonian Andes
(Elsevier, 2020)
The Maastrichtian-Danian transgression was one of the most extensive Atlantic-derived marine incursions in Patagonia. This study examines its stratigraphic record and origin in the Magallanes-Austral Basin, revealing an ...
Burdigalian deposits of the Santa Cruz Formation in the Sierra Baguales, Austral (Magallanes) Basin: Age, depositional environment and vertebrate fossils
(2013)
A succession of marine and continental strata on the southern flank of Cerro Cono in the Sierra Baguales, northeast of Torres del Paine, can be correlated with stratigraphic units exposed along the southern border of the ...
