When considering the rheology of a suspension the fundamental physical aspect to be
quantified is the redistribution of strain between the deformable matrix fraction of the …

The viscosity of silicate melts controls magma transport dynamics, eruption style and rates of
physicochemical processes (eg, degassing, crystallization) in natural magmas. Thus a …

Magma may fragment as it ascends through the volcanic plumbing system to the Earth
surface, forming volcanic ash and pyroclasts (Scheu and Dingwell 2022, this issue). If the …

Glass transition temperatures (Tg) have been determined for natural multicomponent melts
using differential scanning calorimetry. Trachytic, dacitic, phonolitic and basaltic base …

A new category of large-scale volcanism, here termed Snake River (SR)-type volcanism, is
defined with reference to a distinctive volcanic facies association displayed by Miocene …

Welding of pyroclastic deposits involves flattening of glassy pyroclasts under a compactional
load at temperatures above the glass transition temperature. Progressive welding is …

Sintering and densification are ubiquitous processes influencing the emplacement of both
effusive and explosive products of volcanic eruptions. Here we sinter ash‐size fragments of …

The ease at which exsolving volatiles can migrate though magma and outgas influences the
explosivity of a volcanic eruption. Volcanic rocks often contain discrete discontinuities …

Volcanic ash is often deposited in a hot state. Volcanic ash containing glass, deposited
above the glass transition interval, has the potential to sinter viscously both to itself (particle …

There is growing evidence that outgassing through transient fracture networks exerts an
important control on conduit processes and explosive‐effusive activity during silicic …
