Melt extraction with crystal entrainment from basaltic crystal mush, causing a dacitic pumice eruption from the mafic-dominant Iwate volcano, northern Honshu

open access: yesEarth, Planets and Space
The structure and evolution of the magma plumbing system that produced the dacitic Yukiura Pumice (YP) at Iwate volcano, northern Honshu, are constrained by petrography and rhyolite–MELTS simulations. The basaltic Yukiura Scoria (YS) eruption immediately

Trace Element Constraints on the Differentiation and Crystal Mush Solidification in the Skaergaard Intrusion, Greenland [PDF]

open access: yesJournal of Petrology, 2018
New major and trace element analyses of plagioclase and clinopyroxene in gabbros from the Skaergaard intrusion are used to understand the mechanisms of crystallization in the main magma body and in the crystal mush. Crystal cores show a continuous chemostratigraphic evolution in the Layered Series, with compatible elements (e.g.

The permeability of loose magma mush [PDF]

open access: yes, 2023
Models for the evolution of magma mush zones are of fundamental importance for understanding magma storage, differentiation in the crust, and melt extraction processes that prime eruptions.

Transport of melt, pressure and heat through a magma mush

open access: yesFrontiers 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

Quartz‐Hosted Melt Inclusions as Windows Into Magma Assembly and Storage Processes in the Youngest Toba Tuff

open access: yesGeochemistry, Geophysics, Geosystems, 2021
Quartz‐hosted melt inclusions are windows into the assembly and storage of compositionally zoned magmas systems like the giant magma body responsible for the 2,800 km3 Youngest Toba Tuff (YTT), Indonesia.

Fossilized solidification fronts in the Bushveld Complex argue for liquid-dominated magmatic systems

open access: yesNature 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 ...

Partial melting of amphibolitic lower crust and subsequent melt-crystal separation for generation of the Early Eocene magmatism in eastern Himalaya

open access: yesFrontiers in Earth Science, 2023
The Himalayan leucogranites provide a good opportunity to investigate the crustal evolution of the southern Qinghai-Tibet Plateau. In this study, we present zircon U-Pb and monazite U-Th-Pb ages, zircon Hf isotopes and whole-rock Sr-Nd-Pb isotopes and ...
