Interaction of Ca-Mg Carbonates with Rare Earth Element bearing Fluids under Ambient and Hydrothermal Conditions
This thesis aims to investigate the mechanisms of formation of hydroxylbastnäsite, a significant source of rare earth elements, in order to uncover the fundamental principles governing its crystallisation. The precise ... -
Structure and evolution of the upper mantle of the Australian Plate and North Atlantic Ocean from waveform tomography
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2023)With the expansion of regional and global seismic networks and the advancing of tomographic techniques, tomography models are able to reveal the heterogeneities in the Earth's interior with an increasing amount of detail. ... -
The basement geology of the Porcupine High - a key transatlantic link between the Caledonides and Appalachians
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2023)In order to better reconstruct the basement geology of the western Irish offshore and the North Atlantic, constraining the geologic evolution of the Porcupine High region is key. Located 200 km west of Ireland, the Porcupine ... -
Cobalt of the Tyrone Igneous Complex: geochemistry of mafic hosted sulphides and remobilisation
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2023)Primary sulphide mineralisation in mafic rocks and secondary remobilised sulphides contain significant cobalt and relate to early Palaeozoic ocean closure and arc-continent collision in the Irish Caledonian terrane. This ... -
The Akcal Epithermal Deposit: An Example of Low-Sulfidation Gold Mineralization in Western Turkey
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2023)The Akcal epithermal Au-Ag deposit is located on the Biga Peninsula, southwestern Turkey and is estimated to contain 32.5 million tonnes of mineralization at an average grade of 1.03 g/t Au, equivalent to 33.5 tonnes of ...
