Internal structure of the Late Triassic Central Patagonian batholith at Gastre, southern Argentina: Implications for pluton emplacement and the Gastre fault system
(Geological Society of America, 2017-10)
The Central Patagonian batholith (CPB) comprises two Late Triassic calcalkaline plutonic suites (the Gastre superunit of 221 ± 2 Ma and the Lipetrén superunit of 215 ± 1 Ma) which have been interpreted as a record of major ...
Middle Triassic trachytic lava flows associated with coeval dyke swarm in the North Patagonian Massif: A postorogenic magmatism related to extensional collapse of the Gondwanide orogen
(Pergamon-Elsevier Science Ltd, 2017-04)
The Marifil Volcanic Complex is an extended volcanic and pyroclastic unit outcropping in the North Patagonia. It has been included in the Chon Aike large igneous province associated to the thermal anomaly of the Karoo ...
Rifting evolution of the Malvinas basin, offshore Argentina: New constrains from zircon U–Pb geochronology and seismic characterization
(Elsevier Science, 2019-11)
The Malvinas basin, emplaced offshore southern Patagonia, is an asymmetric extensional basin formed by NNW-striking faults. In this contribution we present a review and updated structural framework for the Malvinas basin, ...
U–Pb geochronology of the meta-volcanic rocks from Sierra de Calcatapul: Implications for the Middle Triassic syn-rift volcanism and tectonic evolution of northern extra-Andean Patagonia
(Pergamon-Elsevier Science Ltd, 2021-06)
This contribution deals first new ICP-MS U–Pb zircon ages that indicate Middle- and Late Triassic magmatic episode and tectonometamorphic events, respectively, for the central Patagonia region, instead of a Paleozoic history ...
A Provenance Analysis from the Lower Jurassic Units of the Neuquén Basin. Volcanic Arc or Intraplate Magmatic Input?
(Springer, 2018)
A possible signal of the Jurassic Chon Aike Igneous Province within the early infill of the Neuquén Basin is recognized in our provenance analyses. We use a combination of detrital zircon geochronology and Lu-Hf isotope ...
Mudanças hidroclimáticas e no padrão de oxigenação de água de fundo ao longo do limite Triássico-Jurássico na seção Levanto-Maino, Peru: possíveis gatilhos vulcânicos
(Universidade do Vale do Rio dos Sinos, 2022-03-03)
The evolution of the Earth is marked by different periods of mass extinction, the main five being called the Big Five. Often these extinctions are associated with Large Igneous provinces (LIPs). The Triassic-Jurassic ...
