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 ... -
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 ... -
Uranium-lead geochronology applied to pyrope garnet with very low concentrations of uranium
(2023)We present U–Pb dates from peridotitic pyrope-rich garnet from four mantle xenoliths entrained in a kimberlite from Bultfontein, South Africa. Garnet dates magmatic emplacement due to the high mantle residence temperatures ...
