The Impact of Ice Caps on the Mechanical Stability of Magmatic Systems: Implications for Forecasting on Human Timescales

open access: yesFrontiers in Earth Science, 2022
Monitoring the activity of subglacial volcanoes along the Aleutian Arc in Alaska is important to the safety of local populations, as well as air traffic flying through the region.

A 5-km-thick reservoir with > 380,000 km3 of magma within the ancient Earth's crust

open access: yesScientific 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.

Dynamics of Magma Mixing in Partially Crystallized Magma Chambers: Textural and Petrological Constraints from the Basal Complex of the Austurhorn Intrusion (SE Iceland) [PDF]

open access: yes, 2017
The Tertiary Austurhorn intrusive complex in SE Iceland represents an exhumed magma chamber that has recorded an extensive history of magma mixing and mingling.

Magmatic karst reveals dynamics of crystallization and differentiation in basaltic magma chambers

open access: yesScientific 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 flow through elastic-walled dikes [PDF]

open access: yes, 2005
A convection–diffusion model for the averaged flow of a viscous, incompressible magma through an elastic medium is considered. The magma flows through a dike from a magma reservoir to the Earth’s surface; only changes in dike width and velocity over ...

Maars to calderas. End-members on a spectrum of explosive volcanic depressions [PDF]

open access: yes, 2015
We discuss maar-diatremes and calderas as end-members on a spectrum of negative volcanic landforms (depressions) produced by explosive eruptions (note—we focus on calderas formed during explosive eruptions, recognizing that some caldera types are not ...

Glass in the submarine section of the HSDP2 drill core, Hilo, Hawaii [PDF]

open access: yes, 2004
The Hawaii Scientific Drilling Project recovered ~3 km of basalt by coring into the flank of Mauna Kea volcano at Hilo, Hawaii. Rocks recovered from deeper than ~1 km were deposited below sea level and contain considerable fresh glass. We report electron

Geometry of the magma chamber beneath Damavand volcano (N Iran) from a joint study of gravity and magnetic data [PDF]

open access: yesInternational Journal of Mining and Geo-Engineering
Imaging 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.
