Andean flat slab subduction through time
(Geological Society of America, 2009)
The analysis of magmatic distribution, basin formation, tectonic evolution and structural styles of different segments of the Andes shows that most of the Andes have experienced a stage of flat subduction. Evidence is ...
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 ...
Magmatism as a probe to the neogene shallowing of the nazca plate beneath the modern chilean flat-slab
(PERGAMON-ELSEVIER SCIENCE LTD,, 2002)
Upper mantle anisotropy beneath Peru from SKS splitting: constraints on flat slab dynamics and interaction with the Nazca Ridge
(Elsevier, 2015-02)
The Peruvian flat slab is by far the largest region of flat subduction in the world today, but aspects of its structure and dynamics remain poorly understood. In particular, questions remain over whether the relatively ...
Long-Term Interactions Between Intermediate Depth and Shallow Seismicity in North Chile Subduction Zone
(2017)
We document interactions between intermediate depth and interplate seismicity in the North Chile subduction zone, over a 25 year period (1990–2015). We show that the 2005 Mw 7.8 Tarapaca slab-pull earthquake was followed ...
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 ...
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 ...
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 ...
Andean evolution at the Guañacos and Chos Malal fold and thrust belts (36°30′-37°s)
(Pergamon-Elsevier Science Ltd, 2007-10)
The Andes between 36°30′ and 37°S represent a Cretaceous fold and thrust belt strongly reactivated in the late Miocene. Most of the features that absorbed Neogene shortening were already uplifted in the late Cretaceous, ...
