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.

Evaluation of crystal mush extraction models to explain crystal-poor rhyolites
Journal of Volcanology and Geothermal Research, 2014Abstract Mush models have become the new paradigm for explaining crystal-poor rhyolites in a variety of settings. Despite this general acceptance, there are cases where this model is problematic. Rhyolites from two specific areas are used to highlight examples where mush extraction models are inconsistent with erupted compositions.

Crystal-mush compaction in the Cohassett flood-basalt flow, Hanford, Washington
Journal of Volcanology and Geothermal Research, 2005Abstract The 40-m-thick central part of the Cohassett flow, which was probably emplaced by inflation of an earlier more Ti-rich flow, exhibits textural evidence of crystal-mush compaction during solidification. Although most of the crystallization started in the roof zone as water circulated through fractures in the crust, plumes of dense crystal ...

Crystal-mush reactivation by magma recharge: Evidence from the Campanian Ignimbrite activity, Campi Flegrei volcanic field, Italy [PDF]
Lithos, 2020 International audienceProcesses of crystal-mush remobilization by mafic magma recharges are often related to the outpouring of largevolumes of silicic melt during caldera-forming eruptions. This occurred for the Campanian Ignimbrite (CI) erup-tion (Campi

Lubrication effects on magmatic mush dynamics [PDF]
Journal of Volcanology and Geothermal Research, 2019 International audienceSilicic magma bodies are formed by repeated injections of mobile magma and reside as a crystal-rich mush. Numerical studies of open-system events have revealed the complexity of mixing and rheological behavior.

Water transfer during magma mixing events: Insights into crystal mush rejuvenation and melt extraction processes [PDF]
American Mineralogist, 2017 Many plutons preserve evidence of magma mixing between hydrous mafic magmas and resident felsic crystal-rich mushes. To investigate water transfer processes in such systems following thermal equilibration, we conducted 24 h experiments to establish the ...

Direct observation of deformation processes in crystal mushes
Journal of Structural Geology, 1996Abstract Isothermal microstructural development in deforming, melt-bearing crystal mushes is studied using synkinematic microscopy and a polyphase, thiocyanate system. The aim of the work is to contribute to the basis for understanding the origin of microstructures in rocks which have undergone melt-present deformation.

An experimental study of melt migration in crystal-rich mushes
2022<p>Increasingly, volcanologists model mature volcanic systems as being fed by stratified magma reservoirs, that is, small lenses of eruptible magma suspended within a larger volume of non-eruptible, crystal-rich mush. Erupted lavas record geochemical evidence for long-term deep storage of distinct magma bodies followed by their ascent and
