The Cobres Plutonic Complex, eastern Puna (NW Argentina): Petrological and structural constraints for Lower Paleozoic magmatism
(Pergamon-Elsevier Science Ltd, 2006-12)
The southern portion of the Cobres Range is studied with an interdisciplinary, petrological–geochemical and structural-cartographic approach. The Cobres Plutonic Complex (CPC) consists of two main plutons, a granodiorite ...
Petrology and geochronology of the San Martín de los Andes batholith: Insights into the Devonian magmatism of the North Patagonian Andes
(Pergamon-Elsevier Science Ltd, 2021-08)
Evidence is growing that a belt of Devonian plutonism is present in the Northern Patagonian segment of the present-day Andes. This plutonism formed along the paleo-Pacific margin of the Gondwana supercontinent. New whole ...
Petrology and geochemistry of Carboniferous siliciclastics from the Argentine Frontal Cordillera: A test of methods for interpreting provenance and tectonic setting
(Pergamon-Elsevier Science Ltd, 2012-07)
Petrological and geochemical characteristics of sandstones and shales from the Carboniferous Cerro Agua Negra Formation (Río Blanco basin, western Argentina) are discussed. The sandstones are mostly feldspathic litharenites ...
Andesites and high-alumina basalts from the central-south Chile high Andes: Geochemical evidence bearing on their petrogenesis
(Springer-Verlag, 1977)
High-alumina basalts from seven High-Andean stratovolcanoes (37 °30′S to 41 °S) have major and trace element (including rare earth elements, REE) that are consistent with derivation by partial melting (typically 10-15%) ...
