Nominally anhydrous minerals such as plagioclase feldspar can hold trace amounts of hydrogen within its crystal structure, offering an alternative approach to measure magmatic water contents. My research focuses on undertaking hydrogen plagioclase-melt partitioning and plagioclase dehydration experiments to refine hydrogen partition and diffusion coefficients. These coefficient constraints will enable more accurate quantification of magmatic water contents and decompression rates of eruptive deposits.
I am supervised by Dr Mike Cassidy and Prof. Jon Blundy, and my DPhil is funded by the NERC Environmental Research Doctoral Training Programme (DTP).
