Origin and evolution of the Mesoarchean Aouéouat greenstone belt and associated gold mineralisation
(Trinity College (Dublin, Ireland). Department of Geology, 2016)This Aouéouat greenstone belt is situated in the Tasiast-Tijirit Terrane of the Reguibat Shield, part of the West African Craton. Petrographic, geochronological, geochemical and isotopic studies of the Aouéouat greenstone ... -
Advances in the detection of particulate matter and aerosols in peat: Exploring Icelandic volcanic activity and multi-source deposition in Ireland
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2024)This Ph.D. research project develops new techniques for the detection of particulate matter and aerosols in peat, a relatively underexplored atmospheric archive and carries out novel investigations of atmospheric deposition ... -
The zircon record of the Sudbury impact crater and its implications for the early Earth
(Trinity College (Dublin, Ireland). Department of Geology, 2016)In the absence of widespread rocks older than 4.0 Ga, the earliest terrestrial material and the only direct evidence for the nature of the Earth's very early crust are tiny zircon crystals. The chemical compositions of ... -
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. ...
