Crustal model of the Southern Central Andes derived from ambient seismic noise Rayleigh-wave tomography
(2018)
The distribution and the interconnection of magmatic bodies beneath volcanic arcs is key to asses volcanic hazard and eruptive processes taking place at convergent margins. We use ambient seismic noise Rayleigh-wave ...
The role of the slab pull force in the late Oligocene to early Miocene extension in the Southern Central Andes (27°-46°S): Insights from numerical modeling
(Pergamon-Elsevier Science Ltd, 2018-02)
Although extensional deformation plays a significant part of Andean history, the causes behind its driving mechanisms and its impact throughout the geological record remain controversial. Through the aid of numerical ...
The Byers Basin: Jurassic-Cretaceous tectonic and depositional evolution of the forearc deposits of the South Shetland Islands and its implications for the northern Antarctic Peninsula
(TAYLOR & FRANCIS INC, 2019)
This paper addresses the Jurassic-Cretaceous stratigraphic evolution of fore-arc deposits exposed along the west coast of the northern Antarctic Peninsula. In the South Shetland Islands, Upper Jurassic deep-marine sediments ...
Taxonomia e contexto geológico da tafoflora da Ilha Dufayel, Ilha King George, Península Antártica
(Universidade do Vale do Rio dos Sinos, 2009-07-30)
Plant remains preserved in levels deposited between the end of Cretaceous to the beginning of Neogene are common in the northern Antarctic Peninsula areas, been found both in the marine and transitional paleonvironments ...

O grupo araxá na região sul-sudoeste do estado de goiás
(2013-06-01)
In the S - SW region of Goiás State, Brazil, the Araxá Group is constituted of a metasedimentary sequence containing schistose and gneissic (garnet-biotite-quartz schists, feldspatic garnet-biotite-quartz schists, ...

Revisiting the crustal structure and kinematics of the central Andes at 33.5 degrees S: implications for the mechanics of andean mountain building
(American Geophysical Union, 2018-05)
The Andean belt is the only present-day active case example of a subduction-type orogeny. However, an existing controversy opposes classical views of Andean growth as an east verging retro wedge, against a recently proposed ...
Provenance of metasedimentary rocks of the Araxá group in the central Brasília beltProveniência das rochas metassedimentares do grupo Araxá na porção central da faixa Brasília
(2019-01-01)
The Araxá Group in the region of Morrinhos – Marcelândia is constituted of pelitic to psammo-pelitic rocks metamorphosed in amphibolite facies, kyanite/ staurolite stability field. Chemical composition and La/Lu, La/Sc, ...
Crustal structure along the southern Central American volcanic front
(American Geophysical Union, 2008-08-20)
Subduction alters continents several ways, including accretion, magmatic addition, mantle wedge serpentinization, and crustal differentiation. These changes affect seismic velocities, so characterizing upper plate crust ...
