Exhumation history of the Andean broken foreland revisited
(Geological Society of America, 2013-04)
The Andean broken foreland in west-central Argentina, located 400–800 km from the Peru-Chile Trench is associated with fl at subduction linked to collision of the oceanic Juan Fernandez Ridge. While the conditions associated ...
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 ...
The development of miocene extensional and short-lived basin in the Andean broken foreland: The Conglomerado Los Patos, Northwestern Argentina
(Pergamon-Elsevier Science Ltd, 2017-01)
The Conglomerado Los Patos is a coarse-grained clastic unitthat crops out irregularly in the San Antonio de los Cobres Valley in thePuna, Northwestern Argentina. It covers different units of theCretaceous-Paleogene Salta ...
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 ...
Inherited basement structures and their influence in foreland evolution: A case study in Central Patagonia, Argentina
(Elsevier Science, 2019-12)
Continental crust exhibits areas of recurrent deformation and reactivation of faults that can be persistent for hundreds of millions of years. Associated with weak lithospheric zones, the characterization of long-lived ...
(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 ...
Structural evolution of The Collón Cura basin: Tectonic implications for the north Patagonian Broken Foreland
(Pergamon-Elsevier Science Ltd, 2019-08)
The distribution and timing of the deformation for the North Patagonian broken foreland is nowadays suggested by expansion and retraction of the orogenic activity during the middle to late Miocene Andean contractional ...
Evolution of the Neogene Andean foreland basins of the Southern Pampas and Northern Patagonia (34°–41°S), Argentina
(Elsevier, 2015-12)
The Pampas plain (30°–41°S) has historically been considered as a sector that evolved independently from the adjacent Andean ranges. Nevertheless, the study of the Pampas showed that it is reasonable to expect an important ...
Middle Eocene-Oligocene Broken Foreland Evolution In The Andean Valle Calchaqui, Nw Argentina: Insights From Stratigraphic, Structural And Provenance Studies
(Wiley, 2013-09)
Two end-member models have been proposed for the Paleogene Andean oreland: a simple W-Emigrating foreland model and a broken-foreland model. We present new stratigraphic, sedimentological and structural data from the ...
Using Fluvial Cyclicity To Decipher the Interaction of Basement- and Fold-Thrust-Belt Tectonics In A Broken Foreland Basin: Vinchina Formation (Miocene), Northwestern Argentina
(Society for Sedimentary Geology, 2015-04)
The Miocene Vinchina Formation is made up of more than 5100 meters of siliciclastic sediments deposited mostly in fluvial environments in a broken foreland basin without any connection with the sea during a period of arid ...
