Upper Plate Controls on the Formation of Broken Foreland Basins in the Andean Retroarc Between 26°S and 28°S: From Cretaceous Rifting to Paleogene and Miocene Broken Foreland Basins
(American Geophysical Union, 2020-06)
Marked along-strike changes in stratigraphy, mountain belt morphology, basement exhumation, and deformation styles characterize the Andean retroarc; these changes have previously been related to spatiotemporal variations ...
Patagonian broken foreland and related synorogenic rifting: The origin of the Chubut Group Basin
(Elsevier Science, 2015-05)
The Central Patagonia is characterized by prominent continental deposits that belong to the Cretaceous Chubut Group Basin, whose tectonic setting remains controversial. It has been interpreted as a foreland basin, an ...
Petrology and provenance of the Toro Negro Formation (Neogene) of the Vinchina broken-foreland basin (Central Andes of Argentina)
(Elsevier, 2014-01)
Detrital modes of sandstones and conglomerates of the Toro Negro Formation (Late Miocene-early Pliocene) were used to analyze the evolution of the broken-foreland stage of the Vinchina Basin (28°30′–29°00′ S and 68°30′–68°20′ ...
The Neocomian of Chachahuén (Mendoza, Argentina): evidence of a broken foreland associated with the Payenia flat-slab
(Geological Society of London, 2014-02)
Isolated marine sedimentary Lower Cretaceous deposits crop out in the foreland of the Neuquén Basin, west-central Argentina. They are the result of an anomalous uplift of the Sierra de Chachahuén in the far foreland region. ...
Seismic interpretation and cenozoic tectonic evolution of the Pozuelos Basin, Andean plateau, Argentina
(Pergamon-Elsevier Science Ltd, 2021-01-24)
The Andean basin formation across the Altiplano-Puna plateau has been mostly associated with: (i) interconnected depozones within a simple eastward-migrating foreland, (ii) isolated depocenters in a broken foreland or (iii) ...
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 ...
Magnetostratigraphy and paleomagnetism of early and middle Miocene synorogenic strata: Basement partitioning and minor block rotation in Argentine broken foreland
(Springer, 2011-04)
Magnetostratigraphic and paleomagnetic studies on early Andean synorogenic strata (Del Crestón Fm.), in the Famatina Belt (28.7°S, 67.5°W) clarify details of chronology that permit calculation of sedimentation rates within ...
Tectonic activity revealed by morphostructural analysis: Development of the Sierra de la Candelaria range, northwestern Argentina
(Elsevier, 2014-10)
The tectonically active broken foreland of NW Argentina is a recent analog of the eastern margin of the Puna plateau during Mio-Pliocene times and likely of other broken forelands worldwide. In order to evaluate active ...
Neogene to Quaternary broken foreland formation and sedimentation dynamics in the Andes of NW Argentina (25°S)
(American Geophysical Union, 2011-04)
The northwest Argentine Andes constitute a premier natural laboratory to assess the complex interactions between isolated uplifts, orographic precipitation gradients, and related erosion and sedimentation patterns. Here ...
Neogene retroarc foreland basin evolution, sediment provenance, and magmatism in response to flat slab subduction, western Argentina
(American Geophysical Union, 2020-05)
Understanding the effects of flat slab subduction on mountain building, arc magmatism, and basin evolution is fundamental to convergent-margin tectonics, with implications for potential feedbacks among geodynamic, magmatic, ...
