Ignimbrites are vast, landscape-modifying deposits composed mainly of pumice fragments
and ash. They derive from the most. hazardous types of explosive volcanic eruptions and …

We propose a mechanism by which massive ignimbrite and layered ignimbrite sequences—
the latter liable to have been previously interpreted as multiple flow units-form by …

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 …

Silicic volcanic eruptions range in style from gently effusive to highly explosive, and may
switch style unpredictably during a single eruption. Direct observations of subaerial rhyolitic …

The Gawler Range Volcanics (GRV) of South Australia are an intracontinental, subaerial
Large Igneous Province (LIP) formed during supercontinent assembly in the …

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 …

Abstract Caldera collapse at Glencoe, Scotland, was incremental and involved complex
movements of numerous fault blocks before formation of the ring fault for which the volcano …

Transitions between effusive and explosive styles of lava dome eruptions are likely
accompanied by changes in lava rheology. The common presence of crystals in dome lavas …
