The Distribution of Precious and Energy-Critical Elements at the Scale of a Porphyry Copper Deposit
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2020)Magmatic-hydrothermal porphyry copper deposits are the world's primary sources of Cu. Moreover, these may contain extractable concentrations of rare metal(loid)s e.g., Se, Te, In, Co, Ge, Ga, Ag, Au and Re. Some of these ... -
The petrography and geochemistry of pyrite-hosted orogenic gold deposits in the Grampian Terrane of north-west Ireland and Scotland
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2020)The Neoproterozoic-Cambrian Dalradian Supergroup of north-west Ireland and central Scotland accommodates vein-hosted gold deposits associated with uplift and deformation during the Ordovician Grampian arc-continent collision ... -
Application of airborne radiometric surveys for large-scale geogenic radon potential classification
(2020)Background: Indoor radon represents an important health issue to the general population. Therefore, accurate radon risk maps help public authorities to prioritise areas where mitigation actions should be implemented. As ... -
Geochemical characterisation of the Late Quaternary widespread Japanese tephrostratigraphic markers and correlations to the Lake Suigetsu sedimentary archive (SG06 core)
(2019)Large Magnitude (6–8) Late Quaternary Japanese volcanic eruptions are responsible for widespread ash (tephra) dispersals providing key isochrons suitable for the synchronisation and dating of palaeoclimate archives across ... -
Microanalysis of Cl, Br and I in apatite, scapolite and silicate glass by LA-ICP-MS
(2020)Constraining the abundance and distribution of halogens in geological materials has the potential to provide novel insights into a broad range of earth system processes (e.g. metasomatism, melting, volatile cycling and ore ... -
Application of micro-computed tomography towards a taxonomic and palaeobiological reassessment of Huxley and Wright's tetrapods from the jarrow assemblage (langsettian, pennsylvanian) co. Killkenny
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2020)The Jarrow assemblage records a diverse collection of fish and tetrapods from the Leinster Coalfield (Langsettian, Pennsylvanian), south east Ireland. Specimens are preserved in an area where the Jarrow Seam thickens ... -
Unifying the Irish Vertical Datum with the Normaal Amsterdams Peil (NAP)
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2020)The local gravity potential value on Malin-Head tide gauge station in Ireland is derived from gravimetric and geometric geoid undulations. The geometric geoid undulations are obtained from GNSS and levelling data. In ... -
A new sensitive method for the simultaneous chromatographic separation and tandem mass spectrometry detection of anticoccidials, including highly polar compounds, in environmental waters
(Elsevier, 2020)A sensitive and selective method was developed and validated for the determination of 26 anticoccidial compounds (six ionophores and twenty chemical coccidiostats) in surface and groundwater samples at parts-per-quadrillion ... -
An investigation of anticoccidial veterinary drugs as emerging organic contaminants in groundwater
(Elsevier, 2020)Intensification of the food production system to meet increased global demand for food has led to veterinary pharmaceuticals becoming a critical component in animal husbandry. Anticoccidials are a group of veterinary ... -
Jurassic evaporites and diapirism along the southern Tanzanian continental margin: Implications for petroleum exploration
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2020)One of the key issues for petroleum exploration along the entire Tanzanian margin is the extent of evaporite deposition and its diapirism. This leads to scenarios for the configuration and relative movement of conjugate ... -
Cryptic evolved melts beneath monotonous basaltic shield volcanoes in the Galápagos Archipelago
(2020)Many volcanoes erupt compositionally homogeneous magmas over timescales ranging from decades to millennia. This monotonous activity is thought to reflect a high degree of chemical homogeneity in their magmatic systems, ... -
Development of a Geogenic Radon Hazard Index–Concept, History, Experiences
(2020)Exposure to indoor radon at home and in workplaces constitutes a serious public health risk and is the second most prevalent cause of lung cancer after tobacco smoking. Indoor radon concentration is to a large extent ... -
Deciphering geochemical signals across a Cambro-Ordovician carbonate platform
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2020)Sulfur isotopes (δ34S) preserve a geological record of seawater sulfate that permit insights into biogeochemical cycling, surface redox conditions and microbial activity over geological time. However, isotopic records from ... -
Chemical zoning and open system processes in the Laacher See magmatic system
(2020)Unravelling the generation of compositionally and thermally zoned magma reservoirs is important to our understanding of the dynamic processes operating in magmatic systems. Here, we present new major and trace element data ... -
Petrological, mineralogical and geochemical peculiarities of Archaean cratons
(2019)The most outstanding features of Archaean cratons are their extraordinary thickness and enduring longevity. Seismically, Archaean cratonic fragments are sharply-bounded deep roots of mechanically strong, cold lithospheric ... -
The trace element and U-Pb systematics of metamorphic apatite and its application in provenance studies
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2020)Apatite is a common accessory mineral in igneous, sedimentary and metamorphic rocks. It has potential as a provenance indicator in clastic sedimentary systems, as it can host a wide variety of trace elements in its crystal ... -
Shallow sampling by multi-shot laser ablation and its application within U-Pb zircon geochronology
(2020)The interaction of incident laser radiation and sample substrate is complex and difficult to predict. Natural zircons are often both structurally and chemically heterogeneous in 3-dimensional space. Encountering growth-related, ... -
Groundwater nitrate reduction versus dissolved gas production: A tale of two catchments
(2017)At the catchment scale, a complex mosaic of environmental, hydrogeological and physicochemical characteristics combine to regulate the distribution of groundwater and stream nitrate (NO3−). The efficiency of NO3− removal ... -
Multi-scale crystallographic ordering in the cold-water coral Lophelia pertusa
(2017)Lophelia pertusa is a widespread colonial cold-water coral which can form large three-dimensional habitats for benthic communities. Although it is known to construct an aragonite skeleton with optically opaque and translucent ...
