Structural control on arc volcanism: The Caviahue-Copahue complex, Central to Patagonian Andes transition (38°S)
(Pergamon-Elsevier Science Ltd, 2006-11)
This paper describes the volcanostratigraphy, structure, and tectonic implications of an arc volcanic complex in an oblique subduction setting: the Caviahue caldera Copahue volcano (CAC) of the Andean margin. The CAC is ...
Motion of continental slivers and creeping subduction in the northern Andes
(Nature Research, 2014)
Along the western margin of South America, plate convergence is accommodated by slip on the subduction interface and deformation of the overriding continent. In Chile, Bolivia, Ecuador and Colombia, continental deformation ...
Variable seismic anisotropy across the Peruvian flat-slab subduction zone with implications for upper plate deformation
(Elsevier, 2021-03)
We performed shear wave splitting analyses to investigate seismic anisotropy across the northern extent of the Peruvian flat-slab subduction region. We used core-mantle refracted SKS, SKKS and PKS phases from teleseismic ...
Overriding plate, mantle wedge, slab, and subslab contributions to seismic anisotropy beneath the northern Central Andean Plateau
(American Geophysical Union, 2016-07)
The Central Andean Plateau, the second‐highest plateau on Earth, overlies the subduction of the Nazca Plate beneath the central portion of South America. The origin of the high topography remains poorly understood, and ...
