Role of cryptic amphibole crystallization in magma differentiation at Hudson volcano, Southern Volcanic Zone, Chile
(Springer, 2010-02)
Hudson volcano (Chile) is the southern most stratovolcano of the Andean Southern Volcanic Zone and has produced some of the largest Holocene eruptions in South America. There have been at least 12 recorded Holocene explosive ...
Mechanical fragmentation and thermal erosion of dyke adjacent host rocks induced by fluid-dynamic shear stress and latent heat release in response to turbulent magma flow
(2022)
We present a quantitative account of the thermodynamical and fluid-mechanical aspects of granitic host rock erosion related to dyke emplacement by considering the latent heat released from the dyke, subsequent thermal ...
The Carran-Los Venados volcanic field and its relationship with coeval and nearby polygenetic volcanism in an intra-arc setting
(Elsevier, 2015)
Understanding the relationship between monogenetic and polygenetic volcanism has been a long-standing goal in volcanology, especially in cases where these two styles of volcanism are coeval and geographically adjacent. We ...

Contrasting magmatic structures between small plutons and batholiths emplaced at shallow crustal level (Sierras de Córdoba, Argentina)
(Pergamon-Elsevier Science Ltd, 2016-11)
Processes like injection, magma flow and differentiation and influence of the regional strain field are here described and contrasted to shed light on their role in the formation of small plutons and large batholiths their ...
Numerical Modeling of Time-dependent Fluid Dynamics and Differentiation of a Shallow Basaltic Magma Chamber
(2010)
This contribution presents a numerical model of time-dependent
physical processes and differentiation in a cooling magma chamber
to obtain the magma and liquid composition and model the distribution
of minerals and H2O ...

(Universidad Nacional Autónoma de México. Centro de Geociencias, 2015-12)
En el borde oriental de la Puna Austral, sierra de Inca Viejo, noroeste de Argentina, aflora el complejo intrusivo Diablillos compuesto por rocas calcoalcalinas de arco representado por monzogranitos, granodioritas, tonalitas ...
