Episodic Jurassic to Lower Cretaceous intraplate compression in Central Patagonia during Gondwana breakup
(Pergamon-Elsevier Science Ltd, 2016-12)
From Lower Jurassic to Lower Cretaceous, several intraplate compression events affected discrete sectors of Central Patagonia, under a general context of crustal extension associated with Gondwana breakup. This was ...
Tectonic events reflected by palaeocurrents, zircon geochronology, and palaeobotany in the Sierra Baguales of Chilean Patagonia
(Elsevier, 2017)
The Sierra Baguales, situated north of the Torres Del Paine National Park in the Magallanes region of southern
Chile, shows awell-exposed stratigraphic sequence ranging fromthe Late Cretaceous to late Pliocene, which ...
Jurassic to Cretaceous (upper Kimmeridgian–?lower Berriasian) calcispheres from high palaeolatitudes on the Antarctic Peninsula: Local stratigraphic significance and correlations across Southern Gondwana margin and the Tethyan realm
(Elsevier Science, 2020-01)
We report Upper Jurassic–Lower Cretaceous (Kimmeridgian-Berriasian) calcispheres from the Ameghino (Nordenskjöld) Formation at high palaeolatitudes on the northern part of the Antarctic Peninsula. The Ameghino Formation ...
The Río de la Plata Craton of Argentina and Uruguay
(Springer, 2018)
The geology and the tectonic evolution of the Río de laPlata Craton is reviewed, taking into account geochronological,isotopic and geophysical data. The craton consistsof voluminous granite-gneissic terrains (2.2?2.1 Ga) ...
Eurydesma–Lyonia fauna (Early Permian) from the Itararé group, Paraná Basin (Brazil): A paleobiogeographic W–E trans-Gondwanan marine connection
(Elsevier Science, 2016-05)
Here, the biocorrelation of the marine invertebrate assemblages of the post-glacial succession in the uppermost portion of the Late Paleozoic Itararé Group (Paraná Basin, Brazil) is for the first time firmly constrained ...
Constraining late paleozoic ice extent in the Paganzo basin of western Argentina: Provenance of the lower Paganzo group strata
(Pergamon-Elsevier Science Ltd, 2021-03)
The western margin of Gondwana records evidence of mid-Carboniferous glaciation (Visean- Bashkirian) in the strata of the Paganzo Basin and adjacent areas.Previous studies focused on constraining the orientations of ice ...
Stratigraphical, sedimentological and palaeofloristic characterization of the Sorocayense Group (Triassic) in Barreal depocenter, San Juan Province, ArgentinaCaracterización estratigráfica, sedimentológica y paleoflorística del Grupo Sorocayense (Triásico) en el área de Barreal, provincia de San Juan, Argentina
(Servicio Nacional de Geología y Minería, 2019-07)
The northern area of Cuyo Basin (west‐central Argentina) corresponds to the Rincón Blanco half-graben, whose filling is arranged into the Rincón Blanco and Sorocayense groups. In the present study, we propose a new ...
Isotopic studies on detrital zircons of Silurian-Devonian siliciclastic sequences from Argentinean North Patagonia and Sierra de la Ventana regions: comparative provenance
(Springer, 2011-12)
The Silurian-Devonian siliciclastic sedimentary units known as Sierra Grande Formation and the upper part of the Ventana Group crop out in the eastern area of the North Patagonian Massif and in the Ventania system, toward ...
Análise de bacia sedimentar e quimioestratigrafia do Grupo Bambuí em Minas Gerais
(Universidade Federal de Minas GeraisUFMG, 2017-11-17)
For a better understanding about the evolution of the Bambuí basin in the state of Minas Gerais, different key-areas were studied from the point of view of sedimentology, stratigraphy and geochemistry. Each of these areas ...
