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

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.

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.

Crystal Resorption as a Driver for Mush Maturation: an Experimental Investigation [PDF]
Journal of PetrologyAbstract The thermal state of a magma reservoir controls its physical and rheological properties: at storage temperatures close to the liquidus, magmas are dominated by melt and therefore mobile, while at lower temperatures, magmas are stored as a rheologically locked crystal network with interstitial melt (crystal mush).

The mechanical response of a magma chamber with poroviscoelastic crystal mush [PDF]
Journal of Geophysical Research: Solid Earth, 2020 Improved understanding of the impact of crystal mush rheology on the response of magma chambers to magmatic events is critical for better understanding crustal igneous systems with abundant crystals. In this study, we extend an earlier model by (Liao et al, 2018) which considers the mechanical response of a magma chamber with poroelastic crystal mush ...

Numerical simulations of the mingling caused by a magma intruding a resident mush [PDF]
VolcanicaCurrently, our ability to interpret the mechanics of magma mingling and mixing is limited by an incomplete understanding of the modes of mixing across all melt fractions and compositions.

The Surface Deformation Signature of a Transcrustal, Crystal Mush‐Dominant Magma System
Journal of Geophysical Research: Solid Earth, 2022 AbstractThe transcrustal, mush‐dominated magma storage paradigm, which posits liquid melt is heterogeneously distributed within a vertically extensive magma mush, differs significantly from classical geodetic models, where melt is stored within liquid‐dominant chambers within an elastic crust.

Lithium mica clasts document magmatic evolution prior to eruption in the macusani volcanic field in peru [PDF]
Scientific ReportsTypically found in rare-metal granites and pegmatites, lithium micas are increasingly considered a resource for lithium as global demand surges. In a recently discovered major lithium resource within the Macusani Volcanic Field in Peru, lithium mica ...
