I have used my experience to date to demonstrate in practical for various undergraduate courses, such as: mineralogy and petrology, metamorphic geology, fundation geology and chemistry and for undergraduate earth sciences fieldtrips to Ingleton and Connemara.

Project details

Project title

Understanding REE mobility in solution of carbonatite systems

Supervisors

Dr David Banks, Professor Bruce Yardley and Dr Daniel Morgan

Funding

My PhD project is funded by the SOS Rare porject.

The SOS Rare project is a consortium projet funded by NERC. It is one of the group under the Security of Supply of Mineral Ressources (SoS Minerals) research program. SoS Minerals project initiated to support the security of supply of the strategic elements that reinforce current and future green energy technologies.

SOS Rare research team includes 17 investigators from 6 UK universities and research institutes, with 10 industry partners and 8 core international research collaborators. It will tackle the question of REE concentration in natural systems; to then develop improved recovery processes from the primary sources in order to moderate the environmental effects of extraction and recovery of these elements.

Start date

1 September 2015

Project outline

Research on REE transport in geological systems has increased over the past decade due to the growing demand for REE in high technology applications and a range of costumer products. The recent REE shorthage has attracted interest in carbonatite related systems due to their potential high grade. REE transport and stability is well studied at ambient temperature. But until recently high temperature data were limited to extrapolations of thermodynamic data at 25°C. Currently, experimental high temperature on REE transport are available up to 400°C. Cl and F have been well studied but SO4, CO3 and HCO3 complexes are relativelky overlooked.

Understanding REE mobility and transport in carbonatite-related natural systems requires analytical data of both carbonatite fluids and gydrothermal fluids associated with REE mineralisation. This information would allow modelling of REE-mineralising natural fluids in order to determine which complexes and type of reaction exist in natural carbonatite systems.

The overall aim of this project is to understand the nature of processes leading to REE minerlisation and in particular what leads to HREE enrichment in certain carbonatite deposit.
