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 ...
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) ...
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, ...
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′ ...
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 ...
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 ...
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 vs. climate controls on the evolution of a miocene intermontane basin, Patagonian Andean foreland, Argentina
(Springer, 2021-07)
The interaction of tectonics and climate is considered the main determining factor in the development of different depositional systems (from aeolian to alluvial to lacustrine environments) in intermontane basins. The role ...
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 ...
