The Jáchal river cross-section revisited (Andes of Argentina, 30°S): Constraints from the chronology and geometry of neogene synorogenic deposits
(Pergamon-Elsevier Science Ltd, 2020-09)
In the southern Central Andes, between 27 and 33°S, a flab-slab subduction has been established since the last 10 Ma. This particular subduction geometry has been proposed to control the eastward migration of the deformation, ...
Paleogene and Neogene magmatism in the Valle del Cura region: New perspective on the evolution of the Pampean flat slab, San Juan province, Argentina
(Pergamon-Elsevier Science Ltd, 2007-09)
El Valle del Cura está geológicamente caracterizado por una espesa secuencia volcánica y volcániclástica que registra la evolución del magmatismo terciario de arco y retroarco de la Cordillera Frontal de Argentina sobre ...
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 ...
A Pliocene–Pleistocene continental biota from Venezuela
(Springer, 2021-05)
The Pliocene–Pleistocene transition in the Neotropics is poorly understood despite the major climatic changes that occurred at the onset of the Quaternary. The San Gregorio Formation, the younger unit of the Urumaco Sequence, ...
Neogene Growth of the Patagonian Andes
(Springer International Publishing, 2018)
After a Late Cretaceous to Paleocene stage of mountain building, the North Patagonian Andes were extensionally reactivated leading to a period of crustal attenuation. The result was the marine Traiguén Basin characterized ...
Neogene deformation and its implications for the structural framework of the oil fields in the Icapuí-Ponta Grossa (CE) region, onshore Potiguar BasinDeformação neógena e suas implicações na estruturação dos campos de petróleo na região de Icapuí-Ponta Grossa (CE), Bacia Potiguar emersa

Synsedimentary broken-foreland tectonics during the Paleogene in the Andes of NW Argentine: new evidence from regional to centimetre-scale deformation features
(Wiley Blackwell Publishing, Inc, 2018-02)
Unravelling the spatiotemporal evolution of the Cenozoic Andean (Altiplano-Puna) plateau has been one of the most intriguing problems of South American geology. Despite a number of investigations, the early deformation and ...
Spatio-temporal variation of the strain field in the southern Central Andes broken-foreland (27 degrees 30 ' S) during the Late Cenozoic
(Elsevier BV, 2021-03)
We present an integrated structural and Anisotropy of Magnetic Susceptibility (AMS) study focused on the characterization of the spatio-temporal variation of the strain field during the main Neogene deformation, of the ...
New data on neotectonic contractional structures in Precordillera, south of Río de La Flecha: Structural setting from gravity and magnetic data. San Juan, Argentina
(Elsevier, 2014-01)
The Central and Eastern Precordillera form oppositely verging thrust systems on the western and eastern sides of the Matagusanos-Maradona-Acequión valley, establishing a thick-skinned triangle zone with significant changes ...
