Feeding of a magma chamber by an ascending magma bubble [PDF]
Geophysical Journal International, 2021 There is evidence that magma chambers are not fed by a continuous flow, but in the form of discrete magma batches. The possibility is considered that the chamber is fed by a magma bubble ascending through the region underneath, driven by buoyancy force ...

Orientation of the eruption fissures controlled by a shallow magma chamber in Miyakejima [PDF]
Frontiers in Earth Science, 2016 Orientation of the eruption fissures and composition of the lavas of the Miyakejima volcano indicate tectonic influence of a shallow magma chamber on the distribution of eruption fissures.

Forecasting magma-chamber rupture at Santorini volcano, Greece. [PDF]
Sci Rep, 2015 How much magma needs to be added to a shallow magma chamber to cause rupture, dyke injection and a potential eruption? Models that yield reliable answers to this question are needed in order to facilitate eruption forecasting. Development of a long-lived

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement
Geophysical Monograph Series, Page 27-82., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Stress fields around magma chambers influenced by elastic thermo-mechanical deformation: implications for forecasting chamber failure [PDF]
, 2021 Defining the conditions that lead to the rupture of a magma chamber is essential to forecast eruptions. So far, models simulating magma chamber dynamics have neglected the effects of elastic thermal expansion in the host rocks surrounding a new injection

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 ...

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.
