Evidence for explosive silicic volcanism on the Moon from the extended distribution of thorium near the Compton-Belkovich Volcanic Complex (2014)
Journal Article
Wilson, J., Eke, V., Massey, R., Elphic, R., Jolliff, B., Lawrence, D., …Teodoro, L. (2015). Evidence for explosive silicic volcanism on the Moon from the extended distribution of thorium near the Compton-Belkovich Volcanic Complex.

We reconstruct the abundance of thorium near the Compton-Belkovich Volcanic Complex on the Moon, using data from the Lunar Prospector Gamma Ray Spectrometer. We enhance the resolution via a pixon image reconstruction technique and find that the thori...

The α-β phase transition in volcanic cristobalite (2014)
Journal Article
Damby, D., Llewellin, E., Horwell, C., Williamson, B., Najorka, J., Cressey, G., & Carpenter, M. (2014). The α-β phase transition in volcanic cristobalite. Journal of Applied Crystallography, 47(4), 1205-1215. https://doi.org/10.1107/s160057671401070x

Cristobalite is a common mineral in volcanic ash produced from dome-forming eruptions. Assessment of the respiratory hazard posed by volcanic ash requires understanding the nature of the cristobalite it contains. Volcanic cristobalite contains couple...

Distribution of dissolved water in magmatic glass records growth and resorption of bubbles (2014)
Journal Article
McIntosh, I., Llewellin, E., Humphreys, M., Nichols, A., Burgisser, A., Schipper, C., & Larsen, J. (2014). Distribution of dissolved water in magmatic glass records growth and resorption of bubbles. Earth and Planetary Science Letters, 401, 1-11. https://doi.org/10.1016/j.epsl.2014.05.037

Volcanic eruptions are driven by the growth of gas bubbles in magma. Bubbles grow when dissolved volatile species, principally water, diffuse through the silicate melt and exsolve at the bubble wall. On rapid cooling, the melt quenches to glass, pres... Read More about Distribution of dissolved water in magmatic glass records growth and resorption of bubbles.

Controls on variations in cristobalite abundance in ash generated by the Soufrière Hills volcano, Montserrat in the period 1997-2010 (2014)
Journal Article
Horwell, C., Hillman, S., Cole, P., Loughlin, S., Llewellin, E., Damby, D., & Christopher, T. (2014). Controls on variations in cristobalite abundance in ash generated by the Soufrière Hills volcano, Montserrat in the period 1997-2010. Memoirs, 39, 399-406. https://doi.org/10.1144/m39.21

The Soufrière Hills Volcano (SHV) crystallizes cristobalite (crystalline silica) in its lava domes, and inhalation of cristobalite-rich ash may pose a chronic respiratory hazard. We investigate the causes of variation in cristobalite abundance (measu...
