The co-evolution of Earth's crust and hydrosphere : a silicon isotope perspective
(2024-06-13) - ThesisThe silicon isotope system is a well-established geochemical tool for tracing processes influenced by the interplay of Earth’s present-day crust and hydrosphere. While there is good understanding of stable silicon (Si) ... -
Development of a 1-D oxygen isotope photochemical model and its application to atmospheric O₂
(University of St Andrews, 2021-06-30) - ThesisOxygen is the second most abundant gas in the Earth’s atmosphere, but this has not always been the case. A suite of geochemical, palaeobiological, and geological proxies have been presented over the last few decades to ... -
Whodunit? Determining the source and eruptive characteristics of unidentified volcanic eruptions from ice and sediment core archives
(2024-06-13) - ThesisThe most complete records of explosive volcanism from the last 100,000 years are preserved in polar ice cores as deposits of sulfate aerosol and microscopic ash (tephra). These records are essential for reconstructing the ... -
A quantitative classification tool for porphyry Cu alteration systems
(2023-11-28) - ThesisPorphyry copper deposits form from upper crustal H₂O saturated magmatic systems, along ancient and active convergent margins. As the world’s major source of copper, gold and molybdenum, along with minor quantities of other ... -
A thermodynamic modelling approach to predict the outcome of carbonaceous fluid metasomatism on Earth and Mars
(2023-11-28) - ThesisThe carbon flux between the atmosphere and the geosphere is linked by a broad range of geodynamic and magmatic processes which govern the deep carbon cycles on all telluric planets, asteroids, and moons. On Earth, carbon ...
