The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 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 and Strain in Magma‐Mush Reservoirs: Implications for Reservoir Failure and Magma Propagation [PDF]
Journal of Geophysical Research: Solid EarthAbstract Investigating the mechanical stability and failure of magma reservoirs following magma supply is critical for volcanic hazard assessment. While magma reservoirs were traditionally modeled as melt‐filled cavities, they are now more often described as crystal mushes where melt flows and is stored in porous networks.

Numerical modelling of magma reservoir processes [PDF]
, 2022 For many years, volcanic and igneous processes were explained by the storage of magma in a melt-rich magma body, where chemical differentiation is controlled by fractional crystallisation. However, this idea for the storage and chemical differentiation of magma in the Earth’s crust has been challenged by data from natural magmatic systems.

Formation and dynamics of magma reservoirs [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2019 The emerging concept of a magma reservoir is one in which regions containing melt extend from the source of magma generation to the surface. The reservoir may contain regions of very low fraction intergranular melt, partially molten rock (mush) and melt lenses (or magma chambers) containing high melt fraction eruptible magma, as well as pockets of ...

Magma reservoir growth and ground deformation preceding the 79 CE Plinian eruption of Vesuvius
Communications Earth & Environment, 2023 The 79 CE eruption of Vesuvius is the first documented Plinian eruption, also famous for the archaeological ruins of Pompeii and Herculaneum. Although much is known regarding the eruption dynamics and magma reservoir, little is known about the reservoir ...

The Prevalence and Significance of Offset Magma Reservoirs at Arc Volcanoes
Geophysical Research Letters, 2020 Determining the spatial relations between volcanic edifices and their underlying magma storage zones is fundamental for characterizing long‐term evolution and short‐term unrest.

Exsolved volatiles in magma reservoirs [PDF]
Journal of Volcanology and Geothermal Research, 2018 We review our understanding of the exsolved volatile phase co-existing with magmas during pre-eruptive storage at the pressures and temperatures corresponding to crustal magma reservoirs. We explore the consequences and implications of such a volatile phase for magma and ore body petrogenesis and the fluid dynamics of magma reservoirs.
