Cenozoic intraplate tectonics in Central Patagonia: Record of main Andean phases in a weak upper plate
(Elsevier Science, 2017-11)
Contraction in intraplate areas is still poorly understood relative to similar deformation at plate margins. In order to contribute to its comprehension, we study the Patagonian broken foreland (PBF) in South America whose ...
Transient plate contraction between two simultaneous slab windows: Insights from Paleogene tectonics of the Patagonian Andes
(Pergamon-Elsevier Science Ltd, 2018-11)
Plate kinematic reconstructions show that the Farallon-Phoenix (Aluk) spreading center subducted under South America sometime between the Late Cretaceous and the Paleogene periods. Geological studies have supported a ...
Jurassic intraplate contraction of southern Patagonia: The El Tranquilo Anticline area, Deseado Massif
(Pergamon-Elsevier Science Ltd, 2019-10)
A late Early Jurassic shortening event affected the southern end of the back-arc Chubut Basin in southern Patagonia, interspersed within a general lithospheric extensional context linked to Gondwana breakup. In this work, ...
Cretaceous intraplate contraction in Southern Patagonia: A far-field response to changing subduction dynamics?
(American Geophysical Union, 2018-08-13)
The origin, extent, and timing of intraplate contraction in Patagonia are among the least understood geological processes of southern South America. Particularly, the intraplate Deseado fold-thrust belt (FTB), located in ...
Cenozoic intraplate tectonics in Central Patagonia: Record of main Andean phases in a weak upper plate
(2017)
Contraction in intraplate areas is still poorly understood relative to similar deformation at plate margins. In order to contribute to its comprehension, we study the Patagonian broken foreland (PBF) in South America whose ...
Along-strike segmentation of the Farallon-Phoenix midocean ridge: Insights from the Paleogene tectonic evolution of the Patagonian Andes between 45° and 46°30′S
(Elsevier, 2019)
The kinematics of the Farallon-Phoenix-South America triple junction during the Cretaceous and Paleogene periods remain incompletely resolved. Geological studies have interpreted Paleocene-Eocene ridge subduction beneath ...
Early Jurassic intraplate extension in west-central Argentina constrained by U-Pb SHRIMP dating: Implications for the opening of the Neuquén basin
(Elsevier Science, 2020-11)
The early Mesozoic extensional processes recognized in SW Gondwana have been related to a supercontinent precursor break-up phase, the gravitational collapse of a late Paleozoic orogen, changes in subduction dynamics or ...
Lower Jurassic to Early Paleogene Intraplate Contraction in Central Patagonia
(Springer International Publishing, 2018)
Breakup and dispersion stages of Gondwana were ruled by crustal extension. In Patagonia, this regime was associated with the opening of extensional basins from the Jurassic onwards, a process that was interrupted by the ...
