We consider the current state of our understanding of the rheology of two-phase magmas,
that is suspensions of either bubbles or crystals in a viscous silicate melt. The discussion is …

Explosive volcanic eruptions constitute a major class of natural hazard with potentially
profound economic and societal consequences. Although such eruptions cannot be …

Processes involved in the development of igneous and metamorphic rocks involve some
combination of crystal growth, solution, movement and deformation, which is expressed as …

The rheology of crystal‐bearing magma and lava depends on both the shape and volume
fraction of the suspended crystals. We present the results of analogue rheometric …

Crystals are rarely composed of a single crystal population that have grown solely from the
batch of magma in which they are resident on emplacement, either by eruption or shallow …

Growth histories and residence times of crystals in magmatic systems can be revealed by
studying crystal sizes, size distributions and shapes. In this contribution, serial sectioning …

Crystal measurement, especially on-line measurement, in industrial crystallization is always
a challenging topic in the past years, which is crucial to precisely understand crystal …

Studies of magmatic systems have long used the textures of erupted samples to infer
processes that control the location and duration of magma storage and drive volcanic …

An important goal of petrographers is to analyse rock textures (microstructures) and
compositions in three dimensions, and thus fully quantify rock properties (porosity and …

Transitions between explosive and effusive activity are commonly observed during dome-
forming eruptions and may be linked to factors such as magma influx, ascent rate and …
