Compositional zonation of the shallow La Gloria pluton (Central Chile) by late-stage extraction/redistribution of residual melts by channelization: Numerical modeling
(Elsevier, 2017)
The origin of highly evolved magmas (e.g. rhyolites) has been a long-standing controversy in earth sciences. They
are commonly thought to be generated in the upper crust by melt extraction from mush zones, but due to ...
Generation of tonalitic and dioritic magmas by coupled partial melting of gabbroic and metasedimentary rocks within the deep crust of the Famatinian magmatic arc, Argentina
(Oxford University Press, 2009-05)
The source regions of dioritic and tonalitic magmas have been identified in a deep crustal section of the Famatinian arc (Sierras Pampeanas of western Argentina). The source zones of intermediate igneous rocks are located ...
Dynamics of episodic magma injection and migration at yellowstone caldera: revisiting the 2004-2009 episode of caldera uplift with InSAR and GPS data
(AMER Geophysical Union, 2021)
The 2004-2009 caldera uplift is the largest instrumentally recorded episode of unrest at Yellowstone caldera. We use GPS and Interferometric Synthetic Aperture Radar (InSAR) time series spanning 2004-2015, with a focus in ...
Multiple melt bodies fed the AD 2011 eruption of Puyehue-Cordón Caulle, Chile
(Nature Publishing Group, 2015-12)
Within the volcanological community there is a growing awareness that many large- to small-scale, point-source eruptive events can be fed by multiple melt bodies rather than from a single magma reservoir. In this study, ...
The temporal evolution of back-arc magmas from the Auca Mahuida shield volcano (Payenia Volcanic Province, Argentina)
(Elsevier Science, 2016-09)
In order to better constrain the temporal volcanic activity of the back-arc context in Payenia Volcanic Province (PVP, Argentina),we present newK?Ar dating, petrographic data,major and trace elements from23 samples collected ...
THE HIGH-K CALC-ALKALIC SERRA DA LAGOINHA BATHOLITH, STATES OF CEARÁ AND PARAÍBA: COEXISTENCE AND MIXING OF DIORITIC AND QUARTZ MONZONITIC TO GRANITIC MAGMASO BATOLITO CALCIO-ALCALINO DE ALTO- K DA SERRA DA LAGOINHA, ESTADOS DO CEARÁ E PARAÍBA: COEXISTÊNCIA E MISTURA DE MAGMAS DIORÍTICOS COM MAGMAS QUARTZO MONZONÍTICOS A GRANÍTICOS

The composition of amphibole phenocrysts in Neogene mafic volcanic rocks from the Puna plateau: Insights on the evolution of hydrous back-arc magmas
(Elsevier Science, 2020-12-01)
In typical Andean arc magmas, amphibole appears as a phenocryst phase only after considerable differentiation. However, some near-primitive volcanic rocks (high-Mg andesites and basalts) from monogenetic centers in the ...
