Geophysical characterization of the upper crust in the transitional zone between the Pampean flat slab and the normal subduction segment to the south (32– 348S): Andes of the Frontal Cordillera to the Sierras Pampeanas
(Lyell Collection, 2014-02)
The Nazca Plate subducting beneath the South American Plate, has strongly influenced Cenozoic-mountain growth in western Argentina and Chile sectors (32-34°S; 70-66° W). Particularly, at these latitudes, the Pampean flat ...

Constraining a mafic thick crust model in the Andean Precordillera of the Pampean flat slab subduction region
(Elsevier, 2015-09-09)
Elastic properties in twelve representative rock samples from Central and Western Precordillera in the Andean backarc region of Argentina between 30 and 31S were estimated from detailed petrological analysis. Thus, P and ...
Oliine-induced iscous anisotropy in fossil strike-slip mantle shear zones and associated strain localization in the crust
(Wiley Blackwell Publishing, Inc, 2021-01)
We propose that strain localization in plate interiors, such as linear belts of intraplate seismicity, may arise from spatial ariations in iscous anisotropy produced by preferred orientation of oliine crystals (CPO or ...
Causes and consequences of flat-slab subduction in southern Peru
(Geological Society of America, 2017-07-27)
Flat or near-horizontal subduction of oceanic lithosphere has been an important tectonic process both currently and in the geologic past. Subduction of the aseismic Nazca Ridge beneath South America has been associated ...
The enigma of crustal zircons in upper-mantle rocks: Clues from the Tumut ophiolite, southeast Australia
(Geological Society of America, 2015)
We suggest a new explanation for the presence of crustally
derived zircons in the upper-mantle rocks of ophiolitic complexes,
as an alternative to subduction-related models. Integrated isotopic
(U-Pb, Hf, and O isotopes) ...
