Spectral Gamma Ray (SGR) Analysis of Sedimentary Environments in Early Continental Rift Basins: Implications for Petroleum Exploration
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2022)Continental rift basins are structures of global geoscientific significance, as they hold over 30% of the world?s giant oil fields and serve as modern day examples of unique biodiversity sites, typically operating as ... -
Constraints on the thermal conditions within the cratonic lithospheric mantle through time
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2022)The stabilization of Earth s first continents is inescapably linked to the formation of the ancient cratonic lithospheric mantle. The cratonic lithospheric mantle is widely considered to have formed as a residue of extreme ... -
Geochemical and mineralogical characterisation of the Caribou Zn-Pb VMS deposit, Bathurst Mining Camp, New Brunswick, Canada
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2022)The Caribou Volcanogenic Massive Sulphide (VMS) Zn-Pb deposit in the Appalachians of Eastern Canada is hosted by Middle Ordovician shale and felsic volcanic rocks and deposited in a back-arc environment. The entire mineralised ... -
Refinement of high-spatial resolution U-Pb geochronological methodologies
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2021)Zircon [ZrSiO4] is a naturally occurring mineral commonly used in geochronological, isotope and elemental geochemical studies. It can form as an accessory phase in a wide variety of magmatic and metamorphic conditions and ... -
A geo-thermochronological study offshore west of Ireland: the timing of exhumation and magmatic activity and the nature of the basement on the Irish Atlantic Margin
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2021)In recent years, the use of multiple low-temperature thermochronometers combined with inverse thermal history modelling of multiple samples on vertical profiles has been shown capable of detecting low magnitude exhumation ... -
Chemostratigraphic Investigation of Early Carboniferous Tuffs and Limestones from the Irish Midlands Based on Geochemical and Geochronological Fingerprinting
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2021)The timing of mineralisation of the Irish Zn-Pb ore field is currently poorly understood. It can be improved by more accurate stratigraphic correlations of the Carboniferous (Mississippian Subsystem) host rocks (Heckel ... -
Integrated simulation for improved mineral recovery processes
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2021)The consumption of mineral and metals is increasing as the population grows and the demand for mineral resources will remain high and evolve as society moves towards a carbon-neutral future. The increasing demand for metals, ... -
Fingerprinting and assessing the reactivity of past and future aggregates
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2021)The Irish construction boom of the early 2000s generated an unprecedented demand for sub floor rock aggregate. However, due to a lack of residential specific material standardisation, unacceptable documentation practices ... -
Development of a SEM-EDS method for quantifying free mica in building materials
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2021)The publication of Irish Standard IS 465:2018 highlighted the need for a technique to accurately and non-subjectively quantify free mica.
