Plume overriding triggers shallow subduction and orogeny in the southern Central Andes
(Elsevier Science, 2017-09)
Plate tectonic theory implies that mantle plumes may be eventually overridden by lithosphere during continental drift. These events have particular tectonomagmatic consequences for active margins and hence related orogenic ...
Plume Subduction Beneath the Neuquén Basin and the Last Mountain Building Stage of the Southern Central Andes
(Springer Nature Switzerland AG, 2020)
The occurrence of a Neogene shallow subduction stage, as well as, a Pliocene slab-tearing, and steepening of the Nazca plate in the southern Central Andes are well established. However, a satisfactory explanation for the ...
Contrasting tectonic settings in Northern Chon Aike Igneous Province of Patagonia: subduction and mantle plume-related volcanism in the Marifil formation
(Taylor & Francis, 2019-10-03)
The northern zone of the Chon Aike Igneous Province, located in the North Patagonian Massif,exhibits extensive outcrops of Jurassic volcanic rocks of the Marifil Formation. In the Arroyo Verdearea, the initial volcanic ...
Electrical conductivity of the Pampean Shallow Subduction Region of Argentina near 33 S: evidence for a slab window
(American Geophysical Union, 2013-08)
We present a three-dimensional (3-D) interpretation of 117 long period (20–4096 s) magnetotelluric (MT) sites between 31°S and 35°S in western Argentina. They cover the most horizontal part of the Pampean shallow angle ...
A review about the mechanisms associated with active deformation, regional uplift and subsidence in southern South America
(Pergamon-Elsevier Science Ltd, 2015-12)
A broad range of processes acted simultaneously during the Quaternary producing relief in the Andes and adjacent foreland, from the Chilean coast, where the Pacific Oceanfloor is being subducted beneath South American, to ...
The fate of the Farallon slab beneath Patagonia and its links to Cenozoic intraplate magmatism, marine transgressions and topographic uplift
(Elsevier Science, 2020-11)
The arrival and subsequent stagnation of the Farallon/Nazca slab at the mantle transition zone below southern South America triggered seemingly unrelated large-scale geological processes in the second half of the Cenozoic. ...
Active Deformation, Uplift and Subsidence in Southern South America Throughout the Quaternary: A General Review About Their Development and Mechanisms
(Springer, 2016)
A broad range of processes act today and have acted simultaneously during the Quaternary, producing relief from the Chilean coast, where the Pacific Ocean floor is sinking underneath the South American margin, to the ...
Review and update about the late Triassic to Jurassic tectonics through the transition zone between the southern Central and Patagonian Andes
(International Society for Animal Genetics, 2019)
In the last years, a substantial change has occurred concerning previous concepts accepted for theJurassic tectonics in the area comprehended between the Patagonian and Central Andes. The previoushypothesis conceived a ...
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 ...
