Post-subduction magmatism and mineralisation: the Tuvatu gold deposit, Fiji
Dr Dan Smith
Fiji is home to numerous mineral deposits, that are notable for their enrichment is trace elements and minerals that include high grade gold, as well as ‘critical’ elements such as Te, Pt and Pd, which are becoming increasingly important in e-tech industry and renewable energy (solar panel production). Post-subduction magmatism is a common phenomenon in former volcanic arcs, and is increasingly recognised as an important control on the formation of exceptional deposits. By linking the mineralisation of the Tuvatu caldera to the magmatic evolution, and subsequent interaction between hydrothermal fluids and alkaline host rocks, we aim to build a detailed, process-based genetic model for the deposit. This may then have implications for similar deposits worldwide.
What inspires you?
Since a child I’ve always had an interest in the natural world – I loved seeing volcanic landscapes and visiting volcanoes on holidays, watching Walking with Dinosaurs and collecting bugs. At A-level I studied all sciences, and after a workshop on volcanic risks and hazards at University of Liverpool during year 13 I developed a keen interest in volcanology. During my undergrad experience this has expanded to include igneous geochemistry and petrology. I’ve always loved trying to understand how natural systems work and the implications of their interactions, and seeing how developing our understanding of these systems can lead to positive consequences for humanity.
Prior to my PhD I studied my MSci in Geology at the University of Birmingham
Why did you choose Docotoral Research?
During both my dissertation and master’s project I enjoyed the freedom and independent thinking of research, I find research exciting, and enjoy the challenges, hence I decided that I wished to continue this to a higher level.
Why did you choose a CENTA Studentship?
During my time at Birmingham I spoke to CENTA students who were all really positive about the DTP and the opportunities provided. The close geographical proximity of the universities within CENTA, as well as the training opportunities also makes it stand out. The project itself really stood out to me too though, as whilst it is in line with my interests, I can see the implications this project could have,
