Influence of pre-Andean history over Andean foreland deformation: structural styles in the Malargüe fold-and-thrust belt at 35ºS, Andes of Argentina
(Geological Society of America, 2014-05)
We present the first complete balanced cross-section of the Argentinean Andes at 35ºS. Based on an extensive field survey and limited sub-surface information, we constructed a structural model in which both the tectonic ...
Late oligocene to quaternary tectonic evolution of the extra andean basins of the pampean plain, Argentina
(Pergamon-Elsevier Science Ltd, 2019-10)
The extra-Andean Pampean plain of central Argentina shows a complex evolution history. Three basins were identified in the subsurface (Salado, Macachín and Laboulaye) generated during the opening of the South Atlantic Ocean ...
Chemical weathering and atmospheric/soil CO2 uptake in the Andean and Foreland Amazon basins
(Elsevier B.V., 2011-08)
This study is a geochemical investigation of the Andean and Foreland basins of the Amazon River at high spatial and time resolution, carried out within the framework of the HYBAM research program (Hydro-geodynamics of the ...
The North Patagonian Orogen: Meso-Cenozoic Evolution from the Andes to the Foreland Area
(Springer, 2015)
In the last decades an important amount of studies have dealt with the Patagonian orogen. However, an holistic approach on the evolution of this sector has not been addressed yet. A review of recent advances in different ...
(Un)Coupled thrust belt-foreland deformation in the northern Patagonian Andes: New insights from the Esquel-Gastre sector (41°30′–43°S)
(American Geophysical Union, 2016-11)
The Patagonian Andes represents a unique natural laboratory to study surface deformation in relation to deep slab dynamics. In the sector comprised between latitudes 41°30′ and 43°S, new apatite (U-Th)/He ages indicate a ...
The Iglesia basin in the southern Central Andes: A record of backarc extension before wedge-top deposition in a foreland basin
(Elsevier Science, 2020-10)
The Iglesia basin hosts a key sedimentary archive of the evolution of the southern Central Andes. This basin is classically interpreted as recording the transition from an outer- to an inner-wedge-top (piggyback basin) ...
Salient and recess development in the Agrio - Aluminé fold and thrust belt. Influence of a pre-Andean foreland obstacle
(Istituto Nazionale Di Oceanografia E Di Geofisica, 2013-11)
Curved traces are recurrent features of structural map-view patterns on different fold and thrust belts (FTB) of the world . Although curving FTB frequently reflect pre-deformational thickness of the sedimentary basin fill ...
The Neuquen group: The reconstruction of a Late Cretaceous foreland basin in the southern Central Andes (35-37 degrees S)
(2019)
In the southern Central Andes of Argentina, between 34 degrees and 41 degrees S, the Neuquen Group records Upper Cretaceous nonmarine deposits that provide direct evidence of synorogenic sedimentation associated with the ...
Tectonic inheritance and structural styles in the Andean fold-thrust belt and foreland basin
(Elsevier, 2022)
Andean orogenesis is expressed in the diverse deformational records of crustal structures and sedimentary basins in western South America. Here we summarize retroarc structural styles within the Andean orogenic belt and ...
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 ...
