The Mechanical Response of a Magma Chamber With Poroviscoelastic Crystal Mush
Journal of Geophysical Research: Solid Earth, 2020 Improved understanding of the impact of crystal mush rheology on the response of magma chambers to magmatic events is critical for better understanding crustal igneous systems with abundant crystals.

A 5-km-thick reservoir with > 380,000 km3 of magma within the ancient Earth's crust
Scientific Reports, 2022 Several recent studies have argued that large, long-lived and molten magma chambers may not occur in the shallow Earth’s crust. Here we present, however, field-based observations from the Bushveld Complex that provide evidence to the contrary.

Thermal properties of vesicular rhyolite [PDF]
, 1994 Thermal diffusivity of rhyolite melt and rhyolite foam (70–80% porosity) has been measured using the radial heat transfer method. Cylindrical samples (length 50–55 mm, diameter 22 mm) of rhyolite melt and foam have been derived by heating samples of ...

Magmatic karst reveals dynamics of crystallization and differentiation in basaltic magma chambers
Scientific Reports, 2021 An understanding of magma chamber dynamics relies on answering three important yet highly controversial questions: where, why, and how magma chambers crystallize and differentiate.

Magma chamber formation by magma intrusion into the Earth’s crust
Computational Continuum Mechanics, 2018 <p>The main mechanism of transport of magma in the Earth&#8217;s crust is the formation of cracks, or dikes, through which the melt moves towards the surface under the action of buoyancy forces and tectonic stresses.

A three-dimensional study of a crustal low velocity region beneath the 9°03′N overlapping spreading center [PDF]
, 2003 Overlapping spreading centers (OSCs) play a key role in models of magma distribution at fast spreading ridges. To investigate the relationship between ridge-axis discontinuities and magma supply, we conducted a three-dimensional seismic reflection and ...

Geometry of the magma chamber beneath Damavand volcano (N Iran) from a joint study of gravity and magnetic data [PDF]
International Journal of Mining and Geo-EngineeringImaging the intra-sediment magma chamber in the Damavand region, northern Iran, is beyond the resolution of the local seismic observations. Gravity anomalies can precisely image the lateral extension of magma reservoir.
