Porosity evolution of mafic crystal mush during reactive flow [PDF]
Nature Communications, 2023 The emergence of the “mush paradigm” has raised several questions for conventional models of magma storage and extraction: how are melts extracted to form eruptible liquid-rich domains?

The thickness of the crystal mush on the floor of the Bushveld magma chamber [PDF]
Contributions To Mineralogy and Petrology, 2017 The thickness of the crystal mush on magma chamber floors can be constrained using the offset between the step-change in the median value of dihedral angles formed at the junctions between two grains of plagioclase and a grain of another phase (typically clinopyroxene, but also orthopyroxene and olivine) and the first appearance or disappearance of the

Compositional boundary layers trigger liquid unmixing in a basaltic crystal mush [PDF]
Nature Communications, 2019 This study seeks to tackle the question of why intermediate magmatic rock compositions are poorly represented on the Earth’s surface. The authors do so by tracking the evolution of the physical behaviour of immiscible Fe-rich liquids within a sample ...

Mesoscale and microscopic structures record compaction and crystal-melt segregation in silicic mushes [PDF]
Scientific ReportsGravitationally-driven compaction has been proposed as an important mechanism for crystal-melt segregation in silicic mushes. However, there is no microstructural evidence of crystal deformation consistent with compaction in silicic plutonic rocks.

Insights for crystal mush storage utilizing mafic enclaves from the 2011–12 Cordón Caulle eruption [PDF]
Scientific Reports, 2022 Two distinct types of rare crystal-rich mafic enclaves have been identified in the rhyolite lava flow from the 2011–12 Cordón Caulle eruption (Southern Andean Volcanic Zone, SVZ).

Localized rejuvenation of a crystal mush recorded in zircon temporal and compositional variation at the Lassen Volcanic Center, northern California. [PDF]
PLoS ONE, 2014 Zircon ages and trace element compositions from recent silicic eruptions in the Lassen Volcanic Center (LVC) allow for an evaluation of the timing and conditions of rejuvenation (reheating and mobilization of crystals) within the LVC magmatic system. The

Terra Nova, 2023 AbstractThe processes driving the evolution of crystal mushes are often documented in complex systems where crystallization, assimilation, magma replenishment and mixing occur concurrently and are generally overprinted by compaction and deformation.

Crystal scavenging from mush piles recorded by melt inclusions [PDF]
Nature Communications, 2019 The increasingly prevalent view of magmatic systems as mush-dominated challenges the common assumption that melt inclusions record the pre-eruptive storage and processing of the melts they were erupted with.

Multiple mush generations provide insight into the longevity of open-conduit basaltic volcanoes [PDF]
Scientific ReportsInvestigating the dynamics and timescales of magmatic processes in open-conduit basaltic volcanoes is crucial for improving our understanding of explosive eruptions and better assessing volcanic hazards.
