Enrichment of critical elements in granites: melting process or protolith


Dr Tom Argles, Dr Frances Jenner, Dr Kathryn Goodenough, Dr Sam Hammond and Prof. Nigel Harris

PhD Summary

The project investigates the movement and exchange of critical elements such as Lithium within the crust during partial melting and the subsequent enrichment of coarse grained granite intrusions (pegmatites) with rare earth elements. I will be using a multidisciplinary approach combining field work, petrological analysis and geochemistry with the aim of determining what the processes are that results in the enrichment of LCT pegmatites.

What inspires you?

Spending a large portion of my childhood in the countryside I was intrigued as to how the landscape was formed, also I was very much interested in dinosaurs - probably influenced by Jurassic Park! During university I developed a strong interest in igneous and metamorphic geology which led to me progressing an integrated Master’s (MGeol) focusing on fluid rock interaction

Previous Activity

I have just completed a 4-year undergraduate integrated masters (MGeol) course in Earth Sciences at Plymouth University with the MGeol project focusing on fluid rock interaction within the Sutlej valley and Zanskar region, NW India.

Why did you choose Docotoral Research?

By undertaking a PhD research project in the Earth Sciences, I aim to further develop my knowledge of geological processes. I hope to widen my scientific understanding and with my research, add to the scientific community. This project also allows me to further study crustal melting processes within one of the highest mountain ranges on Earth.

Why did you choose a CENTA Studentship?

I was impressed by the level of training offered by a CENTA studentship – this was often more involved than other studentships. Also, the “Speed PhD” training course was definitely one of the factors that helped me choose CENTA. At the same time being able to socialize with people from different scientific fields within CENTA training events was an appealing aspect.

What are your future plans

By studying with a CENTA studentship I think the non-project specific training will help further develop my interdisciplinary skills that I can apply outside of my PhD project. Also, completing my PhD with CENTA I will be able to advance my career within in the Earth Sciences discipline. I hope to also develop transferable skills that can be applied within the scientific community.
