Strain-induced magma fragmentation in explosive eruptions
TL;DR: A model in which a fragmentation criterion, based on a rate-limited crossing of the glass transition, is incorporated into a multiphase fluid-dynamic description of magma ascent demonstrates the feasibility of strain-induced brittle fragmentation of magMA in volcanic eruptions.
Journal ArticleDOI
Permeability development in vesiculating magmas: implications for fragmentation
TL;DR: In this article, the authors proposed that the degree to which magma is fragmented is determined by factors controlling bubble coalescence: magma viscosity, temperature, bubble size distribution, bubble shapes, and time.

Textural studies of vesicles in volcanic rocks: An integrated methodology
Thomas Shea,Bruce F. Houghton,Lucia Gurioli,Katharine V. Cashman,Julia E. Hammer,Barbara J. Hobden +5 more
TL;DR: In this article, the authors describe a methodology for techniques that encompass the entire data acquisition process, from sample collection to quantitative analysis of vesicle size and number using image nesting strategies.
Journal ArticleDOI
A discussion of the mechanisms of explosive basaltic eruptions
TL;DR: In this article, two contrasting models of the dynamics of explosive basaltic eruptions are compared, referred to as the rise speed dependent (RSD) model and the collapsing foam (CF) model.
Journal ArticleDOI
Delayed, disequilibrium degassing in rhyolite magma: Decompression experiments and implications for explosive volcanism
TL;DR: In this article, a series of decompression experiments using crystal-free, rhyolite melt were conducted to examine the development of large supersaturations due to delayed, homogenous (spontaneous) bubble nucleation.

Dynamics of Drop Deformation and Breakup in Viscous Fluids
TL;DR: In this article, the dynamics of drop deformation and breakup in viscous flows at low Reynolds numbers are described. And a short discussion is given of the stability of the shapes of translating drops, and the effects of flow and material parameters on the drop size distribution are summarized.
Journal ArticleDOI
The dynamics of bubble formation and growth in magmas: A review and analysis
TL;DR: In this article, a numerical method has been developed to determine bubble growth rates during volcanic eruptions of basaltic and rhyolitic tephras, and the numerical solutions consider both diffusional and decompressional growth and the effects of magma ascent rates (0-400 cm s−1), magma viscosity (102 to 108 poise), gas solubility, gas content (0.25-5%), and gas diffusivity (10−6 to 10−9 cm2 s− 1) on growth rates.
Journal ArticleDOI
Crystal size distribution (CSD) in rocks and the kinetics and dynamics of crystallization
TL;DR: In this article, the authors provide a formalism for the macroscopic study of kinetic and physical processes affecting crystallization, within which the explicit affect of chemical and physical process on the CSD can be analytically tested.
Journal ArticleDOI
Overview no. 65
TL;DR: In this article, the development of theories for normal grain growth in pure single phase systems is reviewed and a major theme which emerges is the interplay between the topological requirements for space filling and the kinetics of change in mean grain size with time.
