Direct observation of deformation processes in crystal mushes

Journal of Structural Geology, 1996
Abstract 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.

Silicic magmas, crystal mushes, granitic plutons and rhyolitic eruptions

2023
A crystallising magma must necessarily pass through a mushy (crystal-dominated) state before it fully solidifies. Similarly, partially melted magma source regions start out as solid-liquid mixtures, albeit with different initial conditions and physical behaviours to melt crystallisation.

Fast melt expulsion from crystal-rich mushes via induced anisotropic permeability

Earth and Planetary Science Letters, 2021
Abstract Catastrophic eruptions of rhyolitic super volcanoes require large volumes of silicic magma to be extracted from a crystal-rich mush at high rates. However, fast melt extraction is thought to be difficult because of the low permeability of mushes and the high viscosities of silicic melts. Here, we show that induced ephemeral high permeability

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

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.
