Negatively charged ions in the deep Earth : quantifying the chemical speciation of F and N in silicate melts and phases
(2022-11-29) - ThesisNitrogen and fluorine are essential volatile elements to study in the bulk silicate Earth (BSE) due to their respective influence over the onset of habitability on Earth or over physical and chemical properties of the ... -
Carbon and sulfur isotope biosignatures in Mars-analogue hydrothermal environments
(University of St Andrews, 2021-06-30) - ThesisThe study of terrestrial environments that bear similarity to Mars provides valuable information for interpreting data from missions, including how to find evidence of relict life on the red planet. Stable isotope ... -
REE induced defects in minerals : a spectroscopic study
(University of St Andrews, 2020-07-29) - ThesisThis thesis examines the luminescence and mineral physics of Rare Earth Element (REE) bearing minerals as a precursor to developing smart sorting tools for critical metals used in low-carbon technologies. I characterise ... -
Alteration and fluid flow associated with sediment-hosted stratiform copper mineralisation in the 1.1 Ga Midcontinent Rift System, USA
(University of St Andrews, 2020-12-01) - ThesisThe White Pine Cu-Ag deposit is one of the World’s largest examples of a sediment- hosted copper (SHC) mineral system, with a pre-mining resource of >10 Mt of Cu metal. The deposit is located on the southern shore of ... -
Rapid climate change in the glacial North Atlantic : new insights from geochemical records of temperature, CO₂, redox and circulation
(University of St Andrews, 2021-12-01) - ThesisRapid climate change events of the last glacial period are a prime example of the climate system’s ability to flip quickly between different states. These are associated with abrupt shifts in temperature, productivity and ...
