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.

Experimental Simulations of Magma Storage and Ascent [PDF]
, 2017 One of the key issues in utilizing precursor signals of volcanic eruption is to reliably interpret geophysical and geochemical data in terms of magma movement towards the surface. An important first step is to identify where the magma is stored prior to ascent.

Magma ascent in Australian intraplate volcanoes
, 2023 North-east and South-east Australia host basaltic volcanic fields which are still considered active. Despite this, little work has been undertaken to estimate magma ascent rates and subsequent warning times associated with any future eruptions. A volcanological, petrological and textural study was conducted on Mount Quincan, one of the youngest known ...

Modelling chemical advection during magma ascent [PDF]
Geoscientific Model Development, 2023 Modelling magma transport requires robust numerical schemes for chemical advection. Current numerical schemes vary in their ability to be mass conservative, computationally efficient, and accurate.

Magma Ascent and Degassing at Shallow Levels
, 2015 The most dramatic change that magma undergoes while ascending to the surface is volatile loss because of pressure drop. This chapter reviews the main mechanisms by which magma can lose its volatile components to reach the volcanic vent either as a mostly

Numerical modeling of magma ascent dynamics
, 2021 In the world, volcanic systems exhibit a wide range of eruption styles threatening the lives of millions of people. Relatively slow effusive eruptions generate lava flows (low viscosity magma) and lava domes (high viscosity magma) and tend to evolve over

An analytical model for gas overpressure in slug-driven explosions : insights into Strombolian volcanic eruptions [PDF]
, 2012 Strombolian eruptions, common at basaltic volcanoes, are mildly explosive events that are driven by a large bubble of magmatic gas (a slug) rising up the conduit and bursting at the surface.

The trigger mechanism of low-frequency earthquakes on Montserrat. [PDF]
, 2006 A careful analysis of low-frequency seismic events on Soufrie`ere Hills volcano, Montserrat, points to a source mechanism that is non-destructive, repetitive, and has a stationary source location.

A Microphysical Model for Predicting Magma Fragmentation
Geophysical Research LettersExplosive volcanic eruptions occur when coherent bubbly magma breaks apart in a process called “fragmentation.” Accurate conceptual and numerical models of fragmentation are a pre‐requisite for prediction of eruption explosivity. However, existing models,
