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 ...

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.

Transport of melt, pressure and heat through a magma mush
Frontiers in Earth Science, 2023 Prior to intrusion, magma migrates through the crustal plumbing system that likely contains layers or columns of crystal mush. To better understand the behavior of the crustal magmatic system during magmatic unrest, it is important to examine the process

Terra Nova, 2023 AbstractThe 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.

Interfacial growth morphologies in dense eutectic crystal mushes
IMA Journal of Applied Mathematics, 2023 Abstract We consider the interfacial growth morphologies of crystals growing in contact in crystal mushes, with a specific application to those formed by the solidification of basaltic magma. We focus on the particular case of an augite (pyroxene) crystal growing between two plagioclase crystals.

Mush microphysics and the reactivation of crystal‐rich magma reservoirs [PDF]
Journal of Geophysical Research: Solid Earth, 2014 AbstractReactivation and eruption of upper crustal crystal‐rich magma reservoirs (“crystal mushes”) following recharge has recently been invoked in numerous volcanic systems worldwide. Over the last few years, several models have been proposed for the reactivation of such mushes prior to or during eruptions.

Fossilized solidification fronts in the Bushveld Complex argue for liquid-dominated magmatic systems
Nature Communications, 2020 Magma storage zones are debated to either be crystal-dominated mush zones or large liquid-dominated magma chambers. Here, the authors discover fossilized solidification fronts of magnetitite in the Bushveld pluton, which indicate nucleation and crystal ...
