Structure and development of the Andean system between 36◦ and 39◦S
(Elsevier, 2014-01)
One of the main morphological changes along the Southern Central Andes occurs from 36° to 39°S. The northern portion is characterized by prominent basement structures and a thick-skinned orogenic front with relief of over ...
Constraints on the Neogene growth of the central Patagonian Andes at the latitude of the Chile triple junction (45–47°S) using U/Pb geochronology in synorogenic strata
(Elsevier Science, 2018-10)
Desertification of Central Patagonia began between ~14–12 Ma and therefore was not directly connected to the opening of the Drake Passage and initial conformation of the Antarctica ice cap in early Miocene times. Local ...
Tectonic and geomorphic controls on the lacustrine deposits of the Neogene Vinchina basin, northwestern Argentina
(Society for Sedimentary Geology, 2020-02-27)
Two episodes of lacustrine sedimentation, separated by an erosional surface and fluvial sedimentation, took place in the southern part of the broken foreland Vinchina basin (NW Argentina) between 11 and 5 Ma. The lacustrine ...
Constraints on the Neogene growth of the Central Patagonian Andes at the latitude of the Chile triple junction (45-47°S) using U/Pb geochronology in synorogenic strata
(2018)
Desertification of Central Patagonia began between similar to 14-12 Ma and therefore was not directly connected to the opening of the Drake Passage and initial conformation of the Antarctica ice cap in early Miocene times. ...
Mountain building processes at the orogenic front. A study of the unroofing in Neogene foreland sequence (37ºS)Procesos orogénicos en el frente Andino. Estudio de una secuencia de destechado correspondiente a la cuenca de antepaís neógena
(Servicio Nacional de Geología y Minería, 2012-05)
El frente orogénico a los 37°S ha sido construido por, al menos, dos episodios contraccionales, determinados a partir de discordancias angulares entre los depósitos del Eoceno Superior y del Mioceno Superior. Un episodio ...
New age constraints for the Cenozoic marine transgressions of northwestern Patagonia, Argentina (41°-43° S): Paleogeographic andtectonic implications
(Pergamon-Elsevier Science Ltd, 2014-01)
In this contribution we address the current controversial issues related to the age, correlation, tectonic setting and paleogeographic links of the Cenozoic fossiliferous marine strata that crop out in the eastern sector ...
Tectonostratigraphic significance of the neogene sedimentary record of northwestern Austral-Magallanes Basin, Argentinean Patagonia
(Asociación Argentina de Sedimentología, 2019-05)
Despite their geodynamic significance, the stratigraphy and paleoenvironments of the lower-middle Miocene clastic deposits, genetically related to subductiondriven lithospheric processes at the latitude of the Chile Triple ...
Structure and tectonic evolution of the South Patagonian fold and thrust belt: Coupling between subduction dynamics, climate and tectonic deformation
(Elsevier, 2019)
We present an appraisal of structural domains in the SPA (Southern Patagonian Andes),recognizing a thick-skinned BD (Basement domain) and a hybrid thick- and thin-skinnedtectonic systems in the FTB (fold and thrust belt). ...
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 ...
