Thermo-mechanical analysis of the Andean lithosphere over the Chilean-Pampean flat-slab region
(Pergamon-Elsevier Science Ltd, 2017-09)
Flat subduction segments are generally related to cold lithospheric zones, which suggest low Heat flow values and therefore a deeper Curie isotherm. In this study we perform a geophysical analysis by using high - resolution ...
Central Andean mantle and crustal seismicity beneath the Southern Puna plateau and the northern margin of the Chilean-Pampean flat slab.
(American Geophysical Union, 2014-08)
Earthquake hypocenters recorded in the Andean Southern Puna seismic array (25–28°S, 70–65°W) provide new constraints on the shape of the subducting Nazca plate beneath the Puna plateau, the transition into the Chilean-Pampean ...
Thermal and lithospheric structure of the Chilean-Pampean flat-slab from gravity and magnetic data
(Elsevier, 2019)
Flat subduction settings have a direct impact on the lithospheric structure and thermal state of upper plates in active margins. In particular, in the Chilean-Pampean flat subduction zone, the second largest flat subduction ...
New evidence about the subduction of the Copiapó ridge beneath South America, and its connection with the Chilean-Pampean flat slab, tracked by satellite GOCE and EGM2008 models
(Pergamon-Elsevier Science Ltd, 2015-11)
Satellite-only gravity measurements and those integrated with terrestrial observations provide global gravity field models of unprecedented precision and spatial resolution, allowing the analysis of the litho- spheric ...
The Pampean flat-slab of the Central Andes
(Pergamon-Elsevier Science Ltd, 2002-12)
Late Cenozoic Andean deformation in the Pampean segment of Argentina and Chile (27°00′-33°30′S) provides an exceptional opportunity to study the orogenic effects of flat subduction in an active convergent margin. At these ...
Crustal structure of the high Andes in the North Pampean flat slab segment from magnetic and gravity data
(Pergamon-Elsevier Science Ltd, 2017-01)
The Main Andes at the northern Chilean-Pampean flat slab segment were formed by the inversion of late Oligocene to early Miocene extensional depocenters in Neogene times. Their structure, size and depth are loosely constrained ...
Petrogenesis of Miocene volcanic arc rocks over the Chilean-Pampean flat-slab segment of the Central Andes constrained by mineral chemistry
(Universidad de Barcelona, 2014-06)
Miocene arc volcanism is manifested widely in the Valle del Cura-El Indio belt region (29°30´–30° South latitude), in the southern Central Andes of Argentina and Chile. The magmas that fed this volcanism are well represented ...
Crustal structure of the Central Precordillera of San Juan, Argentina (31°S) using teleseismic receiver functions
(Elsevier, 2013-06)
The subduction of the Nazca plate under the South American plate around 31°S is characterized by flat slab geometry. The (Chilean) Pampean flat slab of Argentina associated with the subduction of the Juan Fernandez ridge ...
The Maipo Orocline: a first scale structural feature in the Miocene to Recent geodynamic evolution in the central Chilean Andes.
(2013)
In this paper we show the results of a paleomagnetic study carried out along the western Andes of central Chile from 30° to 36°S. Whereas paleomagnetic analysis from Jurassic to Late Cretaceous rocks in the Pampean flat ...
