Frontiers in Earth Science, 2020 The size, longevity, and mobility of upper-crustal magma mushes, and thus their ability to mix and interact with newly arriving magma batches, are key factors determining the evolution of magma reservoirs.

Pre-eruptive storage constraints of an active crystal mush using mineral-scale techniques
, 2023 Crystal mushes are common conceptual models used to interpret the structure of a magmatic reservoirs in many volcanic environments and are drivers of differentiation that can generate explosive silicic eruptions.

A Scaling for the Permeability of Loose Magma Mush Validated Using X‐Ray Computed Tomography of Packed Confectionary in 3D and Estimation Methods From 2D Crystal Shapes [PDF]
, 2023 Melt percolation through partially molten “mushy” regions of the crust underpins models for magma migration, accumulation, and processes that prime systems for eruption.

Frontiers in Earth Science, 2020 The strength of foliations defined by shape preferred orientation of plagioclase in troctolitic cumulates from the Layered Series of the Skaergaard intrusion, and the Rum Eastern Layered Intrusion, increases as the grains become more tabular, due either ...

The architecture of intrusions in magmatic mush
, 2020 International audienceMagmatic reservoirs located in the upper crust have been shown to result from the repeated intrusions of new magmas, and spend much of the time as a crystal-rich mush.

Large Silicic Eruptions, Episodic Recharge, and the Transcrustal Magmatic System
Geochemistry, Geophysics, Geosystems, 2020 Large silicic eruptions result from rapid evacuation of large, upper crustal reservoirs of silicic magmas. These silicic magmas are thought to be replenished by melt extracted from underlying crystal‐rich source mushes, but the timescales and mechanisms ...

Geosciences, 2021 Constraining the pre-eruptive processes that modulate the chemical evolution of erupted magmas is a challenge. An opportunity to investigate this issue is offered by the interrogation of the crystals carried in lavas.

Geochemistry, Geophysics, Geosystems, 2020 Large silicic magma reservoirs preferentially form in the upper crust of extensional continental environments. However, our quantitative understanding of the link between mantle magmatism, silicic reservoirs, and surface deformation during rifting is ...
