A quantitative understanding of crystallization and solidification is central to appreciating a
variety of phenomena at the interface between volcanology and petrology. Interpretation of …

A correct description and quantification of the geochemical behaviour of REE+ Y (rare earth
elements and Y) and HFSE (high field strength elements) is a key requirement for modeling …

Vesicles in volcanic rocks are frozen records of degassing processes in magmas. For this
reason, their sizes, spatial arrangements, numbers and shapes can be linked to physical …

The vesicularity, permeability, and structure of pumice clasts provide insight into conditions
of vesiculation and fragmentation during Plinian fall and pyroclastic flow-producing phases …

Growth of the andesitic lava dome during eruption of Soufrière Hills Volcano, Montserrat
involved general increases in discharge rate and dome height with superposed fluctuations …

The Etna 122 BC basaltic eruption had two Plinian phases, each preceded and followed by
weak phreatic and phreatomagmatic activity. This study infers changing eruption dynamics …

Magma ascent velocities, v (d H/dt; where H is depth and t is time), can be determined from
decompression rates (d P/dt), and rates of cooling (d T/dt):, where ρ is magma density, P is …

An experimental study of H 2 O exsolution, bubble growth and microlite crystallisation during
ascent (decompression) of silicic magmas in the volcanic conduit is presented. Isobaric and …

In order to characterize the effect of ascent rate on the kinetics of bubble nucleation in a
rhyolitic magma, we performed three series of experiments decompressed at rates of either …

We review observations of bubble size distributions (BSDs) generated during explosive
volcanic eruptions and laboratory explosions, as inferred from vesicle size distributions …
