AFC3D: A 3D graphical tool to model assimilation and fractional crystallization with and without recharge in the R environment
(Elsevier, 2014-03)
AFC3D is an original graphical free software developed in the framework of the R scientific environment and dedicated to the modeling of Assimilation and Fractional Crystallization without (AFC) and with (AFC-r) recharge, ...
The 2006 - 2009 activity of the Ubinas volcano (Peru): Petrology of the 2006 eruptive products and insights into genesis of andesite magmas, magma recharge and plumbing system
(ElsevierNL, 2014-01)
Following a fumarolic episode that started six months earlier, the most recent eruptive activity of the Ubinas volcano (south Peru) began on 27 March 2006, intensified between April and October 2006 and slowly declined ...
Stress fields around magma chambers influenced by elastic thermo-mechanical deformation: implications for forecasting chamber failure
(2021)
Defining the conditions that lead to the rupture of a magma chamber is essential to forecast eruptions. So far, models simulating magma chamber dynamics have neglected the effects of elastic thermal expansion in the host ...
Linking magmatic processes and magma chemistry during the post-glacial to recent explosive eruptions of Ubinas volcano (southern Peru)
(Elsevier, 2020-12-01)
Understanding the links between the magma differentiation processes, the magma plumbing system and the magma composition at arc volcanoes is of paramount importance for volcanic hazard assessment. In this work we focus on ...
The role of magma mixing and mafic recharge in the evolution of a back-arc quaternary caldera: The case of Payún Matrú, Western Argentina
(Elsevier Science, 2016-02)
The Quaternary Payún Matrú volcano is a long-lived edifice that developed a summit caldera 8 km wide, with abundant pre- and post-caldera volcanic activity. It is the main volcano of the Payún Matrú Volcanic Field, which ...
Multi-banded pumice in the Campo de la Piedra Pómez rhyolitic ignimbrite (Southern Puna plateau): Pre-eruptive physical and chemical interactions between mafic and rhyolitic melts
(Pergamon-Elsevier Science Ltd, 2020-04-28)
The rhyolitic Campo de la Piedra Pómez ignimbrite crops out in the Southern Puna of NW Argentina and it isrelated to the youngest caldera-complex (Cerro Blanco caldera complex) of the Central Andes (73 - 4 kyr). Thepresence ...
The Altar porphyry Cu-(Au-Mo) deposit (Argentina): A complex magmatic-hydrothermal system with evidence of recharge processes
(Society of Economic Geologists, 2014-05)
Altar (31° 29' S, 70° 28' W) is a large porphyry Cu-(Au-Mo) deposit with associated epithermal Au-(Ag- Cu) veins located in the Cordillera Principal of southwest San Juan province (Argentina). Altar is a complex ...
Pre-eruptive magmatic processes associated with the historical (218 ± 14 aBP) explosive eruption of Tutupaca volcano (southern Peru)
(Springer Berlin HeidelbergDE, 2020-01)
Magma recharge into a differentiated reservoir is one of the main triggering mechanisms for explosive eruptions. Here we describe the petrology of the eruptive products of the last explosive eruption of Tutupaca volcano ...
Origin of holocene trachyte lavas of the Quetrupillan volcanic complex, Chile: examples of residual melts in a rejuvenated crystalline mush reservoir
(Elsevier, 2018-05-15)
The Quetrupillan Volcanic Complex (QVC) is a stratovolcano placed in the center of a NW-SE volcanic chain, between Villarrica volcano and Lanin volcano, in the Central Southern Volcanic Zone of the Andes. Its youngest ...
