Orientation of the eruption fissures controlled by a shallow magma chamber in Miyakejima

open access: yesFrontiers in Earth Science, 2016
Orientation of the eruption fissures and composition of the lavas of the Miyakejima volcano indicate tectonic influence of a shallow magma chamber on the distribution of eruption fissures.

Evidence for magma mixing/mingling process in the plutonic intrusive bodies of Qorveh (Kurdistan Province): with emphasis on textural and geochemical characteristics [PDF]

open access: yesپترولوژی, 2023
The Qorveh batholith, in the N-Sanandaj-Sirjan Zone, comprises several gabbroic, dioritic and granitic masses intruded the Jurassic metamorphic assemblage (i.e., schist, amphibolite and marble). In spite of a number of studies which have been carried out

The Crustal Magma Storage System of Volcán Quizapu, Chile, and the Effects of Magma Mixing on Magma Diversity [PDF]

open access: yesJournal of Petrology, 2012
Crystal zoning as well as temperature and pressure estimates from phenocryst phase equilibria are used to constrain the architecture of the intermediate-sized magmatic system (some tens of km 3 ) of Volcan Quizapu, Chile, and to document the textural and compositional effects of magma mixing.

Synneusis: does its preservation imply magma mixing? [PDF]

open access: yes, 2018
The Ghansura Felsic Dome (GFD) occurring in the Bathani volcano-sedimentary sequence was intruded by mafic magma during its evolution leading to magma mixing.

Numerical simulation of convection and mixing in magma chambers replenished with CO2-rich magma

open access: yes, 2006
Magma convection and mixing, and periodic refilling, commonly occur in magma chambers.We show here that the presence of CO2 in the refilling magma is a very efficient mean of inducing buoyant-driven plume rise and large scale convection.

Magma ascent and degassing processes of the 2011 and 2017–18 eruptions of Shinmoedake in Kirishima volcano group, Japan, based on petrological characteristics and volatile content of magmas

open access: yesEarth, Planets and Space, 2023
The eruption activity of Shinmoedake in the Kirishima volcanic group of Japan resumed in 2017–18, following a quiet period during 2011–17. Subplinian eruptions preceded lava effusion in 2011; however, no subplinian eruption occurred during 2017–18 ...

Bubble-enhanced basanite–tephrite mixing in the early stages of the Cumbre Vieja 2021 eruption, La Palma, Canary Islands

open access: yesScientific Reports, 2023
Syneruptive magma mixing is widespread in volcanic eruptions, affecting explosivity and composition of products, but its evidence in basaltic systems is usually cryptic.

Streamline and Isotherm Visual Analysis of Darcy–Forchheimer von Karman Spinning Flow of Maxwell Fluid Over a Stretching Disk With Quadratic Temperature‐Dependent Heat Source

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This research paper provides an extensive study of the effects of Darcy–Forchheimer von‐Karman spinning flow of Maxwell fluid across a stretching disk including the effect of heat generation based on a nonlinear function of temperature. The flow system is influenced by thermal radiations and Arrhenius activation energy.
