Flexural uplift and magmatic underplating anomaly on the Argentine continental margin: profile at 43.5°S
(Springer, 2021-05)
Magmatic underplating can be defined as the addition of mafic magma to the lower crust and uppermost mantle around the Moho. This phenomenon plays an important role in continental margins and other compressional and ...
Fast sediment underplating and essentially coeval juvenile magmatism in the Ordovician margin of Gondwana, Western Sierras Pampeanas, Argentina
(Elsevier Science, 2012-09)
Metasedimentary high-pressure upper amphibolite facies gneisses (1.2 ± 0.1. GPa and 780 ± 45 °C) at Las Chacras, Sierra de Valle Fértil, are tectonically juxtaposed to the westernmost parts (outboard) of the Famatinian ...

Petrogenesis of the Triassic Cuyo basin magmatism: Controls on the magmatic evolution of passive rifts basins in Western Gondwana
(Pergamon-Elsevier Science Ltd, 2019-06)
The rifting magmatism of the Cuyo basin (Western Argentina) is characterized by the presence of pyroclastic rocks and basaltic lavas, Triassic in age, emplaced during active faulting that occurred along an ancient terrane ...
Major and trace elements in a granulite facies metagabbro from the Proterozoic high grade terrain of Guaxupe, southeastern Brazil, and the nature of the mantle source

New hints on the evolution of the Eastern Magmatic Belt, Puna Argentina. SW Gondwana margin: Zircon U-Pb ages and Hf isotopes in the Pachamama Igneous-Metamorphic Complex
(Pergamon-Elsevier Science Ltd, 2019-06-27)
There are various geotectonic interpretations of the origin of the Eastern Magmatic Belt as part of the Lower Paleozoic Orogen at the Southwestern Gondwana margin in the Puna, NW Argentina. In this research paper, we ...
Crustal intrusion beneath the Louisville hotspot track
(ELSEVIER, 2010)
We report here the first detailed 2D tomographic image of the crust and upper mantle structure of a
Cretaceous seamount that formed during the interaction of the Pacific plate and the Louisville hotspot.
Results show ...
Arcabouço geofísico, isostasia e causas do magmatismo cenozóico da província Borborema e de sua margem continental (Nordeste do Brasil)
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Geodinâmica e GeofísicaGeodinâmica; Geofísica, 2008-07-27)
The Borborema Province (BP) is a geologic domain located in Northeastern Brazil. The BP is limited at the south by the São Francisco craton, at the west by the Parnaíba basin, and both at the north and east by coastal ...
The role of magma mixing in the evolution of the Early Paleozoic calc-alkaline granitoid suites. Eastern magmatic belt, Puna, NW Argentina
(Pergamon-Elsevier Science Ltd, 2017-07)
The outcrops of the Eastern magmatic belt in Puna, NW Argentina, offer an excellent field laboratory to study the interaction processes between magmas of contrasting composition in a plutonic environment. We evaluate the ...
