Research interests

           

My research focuses on the complex interaction of volcanology and sedimentology, and their links to magmatic and tectonic processes.  My work uses quantitative fieldwork methods, together with petrography, geochemistry and modelling, to investigate volcanic systems and understand their behaviour.  I am particularly interested in the physical volcanology and stratigraphy of pyroclastic eruptions and the role of volcanic and sub-volcanic rocks in unconventional energy systems.  I also apply my expertise in pyroclastic eruptions to understanding meteorite impact ejecta blankets.  I lead Vo@G, the Volcanology at Glasgow research group.

My main research interests are:

Pyroclastic Eruptions

  • Pyroclastic density currents and the sedimentation of ignimbrites: using mapping and logging of complex pyroclastic sequences to understand the nature of pyroclastic eruptions, density current dynamics, and the deposition of ignimbrites (in 4-D)
  • Particle transport in pyroclastic density currents: using field observations, microCT and laboratory modelling to understand the rheology and dynamics of pyroclastic suspensions
  • Caldera-forming eruptions: using field and petrographic observations to understand the eruptive histories of caldera volcanoes and their stratigraphic complexity (in 4-D)
  • Ash aggregates: using field and chemical studies to determine how ash is removed from the atmosphere during eruptions

 

Meteorite Impacts and Ejecta Blankets

  • Impactoclastic density currents: using mapping, logging, mineralogy and geochemistry to understand how meteorite ejecta blankets are deposited
  • The links between meteorite impact and volcanism

 

Volcanic/Sub-Volcanic Rocks and Applied Geology

  • Competing volcanic and sedimentary systems and their role in applied geology: using field and petrographic observations to understand the 3-D and 4-D facies relationships of lavas and interbedded siliciclastic and volcaniclastic rocks (from a variety of palaeo-environmental and tectonic settings), and their potential as reservoirs
  • Diagenesis in volcano-sedimentary systems: using field, petrographic and SEM studies to document the reworking of volcanic material into siliciclastic systems and understand its effect on reservoir quality
  • Emplacement mechanisms of minor intrusions: using field and seismic studies to recognise intrusions and understand their role in reservoir compartmentalisation

 

Research Awards

In 2012, a paper on which I was co-author (Schofield, Brown et al., 2012) won the Young Author Paper of the Year Award of the Journal of the Geological Society.  This paper demonstrates that the rheological response of host rock lithology to intrusion of magma controls the emplacement and morphological evolution of sheet intrusions in high-level magmatic systems in the Earth’s crust.

In 2009, I won the Clough Memorial Award of the Edinburgh Geological Society for my novel work on mass flow deposits in volcanic settings.
