Porosity evolution of mafic crystal mush during reactive flow. [PDF]
Nat Commun, 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?

Insights for crystal mush storage utilizing mafic enclaves from the 2011-12 Cordón Caulle eruption. [PDF]
Sci Rep, 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).

Compositional boundary layers trigger liquid unmixing in a basaltic crystal mush. [PDF]
Nat Commun, 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 ...

Advances in seismic imaging of magma and crystal mush
Frontiers in Earth Science, 2022 Seismic imaging methods have provided detailed three-dimensional constraints on the physical properties of magmatic systems leading to invaluable insight into the storage, differentiation and dynamics of magma.

Consequences of a crystal mush-dominated magma plumbing system: a mid-ocean ridge perspective. [PDF]
Philos Trans A Math Phys Eng Sci, 2019 Crystal mush is rapidly emerging as a new paradigm for the evolution of igneous systems. Mid-ocean ridges provide a unique opportunity to study mush processes: geophysical data indicate that, even at the most magmatically robust fast-spreading ridges ...

Crystal scavenging from mush piles recorded by melt inclusions. [PDF]
Nat Commun, 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.

The thickness of the crystal mush on the floor of the Bushveld magma chamber. [PDF]
Contrib Mineral Petrol, 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

Terra Nova, 2023 The 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.

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

Crystal mush processes and crustal magmatism [PDF]
Nature Reviews Earth & EnvironmentMuch of Earth’s magma is stored as extensive crystal mush systems, yet the prevalence of physical processes operating within mushes and their importance in volcanically active regions remain enigmatic. In this Review, we explore the physical properties and key processes of crystal mush systems. The initiation, evolution and decline of volcanic systems,
