Synthesis: PLUTONS: Investigating the relationship between pluton growth and volcanism in the Central Andes
(Geological Society of America, 2018-06)
The Central Andes is a key global location to study the enigmatic relation between volcanism and plutonism because it has been the site of large ignimbrite-forming eruptions during the past several million years and currently ...
Mantle driven cretaceous flare-ups in Cordilleran arcs
(Elsevier B.V., 2019)
© 2018 The AuthorsContinental arcs display episodic magmatism characterized by flare-ups and lulls. Models published to explain these patterns invoke (1) upper plate crustal processes driven by internal feedback; (2) ...
Detrital chromian spinels from Upper Ordovician deposits in the Precordillera terrane, Argentina: A mafic crust input
(Pergamon-Elsevier Science Ltd, 2009-12)
The study of heavy minerals from the Caradocian Pavón Formation (central Argentina) suggests that MORB and continental intraplate flood basalts were among the source rocks for the detrital record. The Pavón Formation was ...
Incremental growth of an upper crustal, A-type pluton, Argentina: Evidence of a re-used magma pathway
(Elsevier Science, 2017-07)
Carboniferous igneous activity in the Sierra de Velasco (NW Argentina) led to the emplacement of several magmas bodies at shallow levels (< 2 kbar). One of these, the San Blas intrusive complex formed over millions of years ...
Petrogenesis of Early Cretaceous silicic volcanism in SE Uruguay: The role of mantle and crustal sources
(GEOCHEMICAL SOC JAPAN, 2010)
Early Cretaceous (similar to 129 Ma) silicic rocks crop out in SE Uruguay between the Laguna Merin and Santa Lucia basins in the Lascano, Sierra Sao Miguel. Salamanca and Minas areas They are mostly rhyolites with minor ...
Crustal structure of the Eastern Sierras Pampeanas of Argentina using high frequency local receiver functions
(Elsevier Science, 2012-12-28)
The Eastern Sierras Pampeanas are basement cored outcrops uplifted in the Andean foreland where the easternmost segment of the Pampean flat slab segment starts dipping more steeply into the deeper mantle. These ranges of ...
The geodynamic history of the Famatinian arc, Argentina: A record of exposed geology over the type section (latitudes 27°- 33° south)
(Pergamon-Elsevier Science Ltd, 2020-06-14)
The Famatinian arc, over central-western Argentina, is one of the few examples of exposed crustal arc cross-section in the world. This Paleozoic magmatic arc and orogenic system on the Earth's surface offers unique insights ...
