Sedimentary and foliar mercury sequestrations in contemporary and palaeo-environments, and the establishment of a new leaf-based atmospheric mercury proxy
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2025)Gaseous emissions from Phanerozoic large igneous province (LIP) emplacements have been implicated as instigators of global carbon cycle perturbations and associated global change and mass extinction events. However, ... -
The Mesozoic Ridges of the Southern Porcupine Basin
(Trinity College (Dublin, Ireland). Department of Geology, 2014)This dissertation presents a review of the geology and geophysics of the principal intra basinal ridges of the southern Porcupine Basin, offshore south-western Ireland. These ridges, namely the Porcupine Median Volcanic ... -
Addressing the Demand for Green Skills: Bridging the Gap Between University Outcomes and Industry Requirements
(2025)The transition to a green economy requires a workforce equipped with green skills to meet the demands of sustainable development and environmental stewardship. This study investigates the alignment between university ... -
Mechanisms, kinetics and pathways in the early-stage crystallisation of Ca-REE-F-bearing carbonates under ambient and hydrothermal conditions
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2025)The aim of this study is to investigate the reaction pathways, mechanisms, kinetics, and energetics of the REE-CaF2-CaCO3 system crystallization reactions. It also seeks to understand the role of different REEs in the ... -
Upper mantle structure, intraplate volcanism and the unique anisotropy of the Antarctic Plate from waveform tomography
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2025)Antarctica’s unique geological setting makes it an important location for understanding the Earth’s crust and upper mantle, and its connections to the past and future evolution of the Earth. The Antarctic continent has ... -
Tephra identification without pre‐separation in ashed peat
(Wiley, 2024)Cryptotephras in peat and sediment samples are traditionally separated for geochemical characterization using chemical or density floatation techniques following initial tephra identification and shard counting through analysis ... -
Optimizing SEM-EDX for fast, high-quality and non-destructive elemental analysis of glass
(2024)Advancements in scanning electron microscopy and energy dispersive X-ray analysis (SEM-EDX) technologies have reached the point where rapid, fully quantitative, non-destructive and high-resolution acquisition of effectively ... -
Modelling the thermal history of onshore Ireland, Britain and its offshore basins using low-temperature thermochronology
(Trinity College (Dublin, Ireland). Department of Geology, 2017)The main goal of this PhD thesis is to investigate the early Cenozoic exhumation history of Ireland and Britain. The causal mechanism for early Cenozoic exhumation on this sector of the NW European margin remains contentious, ... -
Applications of the LA-ICP-MS image mapping approach to U-Pb carbonate dating : from far-field tectonism to pedogenic nodules
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2024)Carbonates are one of the most common mineral phases in the upper crust, and form in many geological environments (e.g. biotic and abiotic carbonate precipitation, fracture fills in tectonic veins and ore deposits). This ... -
Utilization of radiometric data for mapping primary and secondary sources of gamma radiation and radon/thoron release potentials in Ireland
(2024)Background: This paper presents a novel approach to predict and map radon and thoron levels. We developed separate radon and thoron prediction maps for Ireland and introduced a system for producing high-resolution 3D ... -
Logistic regression model for detecting radon prone areas in Ireland
(2017)A new high spatial resolution radon risk map of Ireland has been developed, based on a combination of indoor radon measurements (n = 31,910) and relevant geological information (i.e. Bedrock Geology, Quaternary Geology, ... -
Examining fish scale biomineral from Atlantic salmon populations
(2024)Fish scale microchemistry can be used to make life-history inferences, although ecological studies examining scale composition are relatively rare. Salmon scales have an external layer of calcium phosphate hydroxyl apatite ... -
Seismic Tomography of South America: Continental Lithosphere, Subduction-Zone Structures, and the Origins of Intraplate Magmatism
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2024)The lithospheric structure of South America records its long and complex tectonic evolution, during which it has influenced the distribution and composition of local magmatism, the geometry of the subduction at its western ... -
Common Era sea-level change in the North Atlantic
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2024)Relative sea-level (RSL) varies in time and space in response to a suite of different controlling mechanisms. The reliable reconstruction of RSL using foraminifera buried in high-saltmarsh sediments enable the development ... -
Back to the future: Comparing Yeast as an outmoded artificial Tracer for simulating microbial transport in Karst aquifer systems to more modern approachs
(2024)Bacterial contamination of karst groundwater is a major concern for public health. Artificial tracing studies are crucial for establishing links between locations where pollutants can rapidly reach the aquifer systems ... -
From synergy to inhibition: Effects of multi component solutions on the crystallization of divalent carbonates in natural and synthetic environments
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2024)The understanding of the processes governing the mechanisms, kinetics, and pathways of carbonate crystallization is crucial in the context of carbon capture and storage through mineralization. However, uncertainty still ... -
Cold-water corals from the deep-sea to the TV: development of shelf-edge mounds, assessment of anthropogenic stressors and geochemical parameters, and impacts of science communication
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2024)Cold-water corals (CWCs) are the hidden reef-builders of the deep ocean. They are out of sight, yet they perform important functions for marine ecosystems, play a role in stabilising climate change, and hold clues to study ... -
Development and physical characteristics of the Irish shelf-edge Macnas Mounds, Porcupine Seabight, NE Atlantic
(2024)Modern cold-water corals (CWCs) occur in a wide range of water depths, with Desmophyllum pertusum being one of the most common species. Pleistocene, Holocene, and modern coral mound formation by living CWC reefs have ... -
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 ...
