Impact vesiculation – a new trigger for volcanic bubble growth and degassing [PDF]
, 2007 We highlight a potentially important trigger for bubble growth and degassing in volcanic bombs. We have successfully triggered bubble growth in previously unvesiculated samples of silicate melt during experiments to simulate volcanic bomb impact, by ...

Dynamics and energetics of bubble growth in magmas: Analytical formulation and numerical modeling [PDF]
, 1998 We have developed a model of diffusive and decompressive growth of a bubble in a finite region of melt which accounts for the energetics of volatile degassing and melt deformation as well as the interactions between magmatic system parameters such as ...

A rheological investigation of vesicular rhyolite [PDF]
, 1992 The rheology of vesiculating rhyolitic systems exerts a strong control on the transport of silicic magmas in the subvolcanic to volcanic environments. We present here an investigation of vesiculating and vesiculated rhyolites using dilatometric methods ...

Геодинамика и тектонофизикаThe paper describes the petrographic and petro-geochemical composition of granitoids of the Khotugu-Eyekit massif and the rhyolite dike of the Sololi uplift. It was revealed that the rocks of the massif are represented by microcline granites.

The Eruption of Submarine Rhyolite Lavas and Domes in the Deep Ocean – Havre 2012, Kermadec Arc
Frontiers in Earth Science, 2018 Silicic effusive eruptions in deep submarine environments have not yet been directly observed and very few modern submarine silicic lavas and domes have been described.

Geochemistry, Geophysics, Geosystems, 2020 Water controls magmatic crystallization and drives volcanic eruptions, but little is known about its primary source in silicic systems. The hydrogen isotope composition of volcanic products provides a metric that can track and identify magmatic source ...

Geochemistry, Geophysics, Geosystems, 2020 We use 3‐D magnetotellurics to improve our understanding of the structure and magma composition of Newberry Volcano in Oregon, USA. Newberry is a broad shield volcano with a summit caldera and strongly bimodal magmatism.
