The Permian to early Triassic granitoids of the Nahuel Niyeu - Yaminué area, northern Patagonia: Igneous stratigraphy, geochemistry and emplacement conditions
(Pergamon-Elsevier Science Ltd, 2021-03)
We present the first geochronologically constrained igneous stratigraphy of the Permian to Early Triassic magmatism of the Nahuel Niyeu and Yaminué areas, northern Patagonia. This magmatism was separated into the Early ...
The Mencué Batholith: Permian episodic arc-related magmatism in the western North Patagonian Massif, Argentina
(Taylor & Francis, 2020-01-08)
The Mencué Batholith, western North Patagonian Massif, includes three major bodies. The Mencué Granodiorite, Cura Lauquén Granite and La Blancura Syenogranite. There are dikes of granitic and basaltic rocks cutting the ...
The Cordon del Portillo Permian magmatism, Mendoza, Argentina, plutonic and volcanic sequences at the western margin of Gondwana

Late triassic- Early jurassic continental extension in SouthWestern Gondwana: Tectonic segmentation and pre-break-up rifting
(Pergamon-Elsevier Science Ltd, 2001-04)
From the earliest Jurassic to the Cenozoic, the Neuquén Basin (central Argentina and Chile) evolved as an intra-arc and transarc-retroarc depression through the gradual development of the Andean magmatic arc. However, the ...
Sedimentary provenance study of the post-Early Permian to pre-Early Cretaceous metasedimentary Duque de York Complex, Chile

The Choiyoi magmatism in South Western Gondwana: Implications for the end-permian mass extinction- A reviewEl magmatismo Choiyoi en el sudoeste de Gondwana: Su implicancia en la extinción en masa del Pérmico tardío-una revisión
(Servicio Nacional de Geología y Minería, 2017-07)
The end of the Permian period is marked by global warming and the biggest known mass extinction on Earth. The crisis is commonly attributed to the formation of large igneous provinces because continental volcanic emissions ...
First late Ordovician paleomagnetic pole for the Cuyania (Precordillera) terrane of western Argentina: A microcontinent or a Laurentian plateau?
(Elsevier Science, 2004-12)
Time and tectonic processes involved in docking of the Argentine Precordillera. (Cuyania terrane) against SW Gondwana has been a matter of much debate. A paleomagnetic study on the Early Caradoc Pavón Formation, exposed ...
Triassic-Jurassic thermal evolution and exhumation of the western Gondwana foreland: Thermochronology and basalt thermobarometry from the Argentine Sierras Pampeanas
(Pergamon-Elsevier Science Ltd, 2020-10)
The geological record of the eastern Sierras Pampeanas province, in the modern Andean broken foreland of Argentina can be divided into four main events: (1) Proterozoic to early Paleozoic collisional tectonics, (2) middle-late ...
Episodic remagnetizations related to tectonic events and their consequences for the South America polar wander path
(Geological Society Publications House, 2012-08)
The South American record of remagnetizations is linked to specific events of its tectonic history stretching back to Precambrian times. At the Ediacaran-Cambrian time interval (570-500 Ma), the final stages of the western ...
