Donegal, Ireland. 2025-02-03 creation http://data.bgs.ac.uk/id/dataHolding/13608340 The project data provided herein represents the U-Pb geochemical data for a suite of magmas from Co. Donegal, Ireland. The aim of this data set is the identification of magmatic and inherited zircon grains. The samples were collected in Donegal in 2023 by Dempsey. Within the data Fan = Fanad Granite, Ard = Ardara Granite, MDG = main Donegal granite, Tull = Tullagh Granite, Thor = Thorr Granite. Crushed an separated in Glasgow by Dempsey (23-24). Prepared in Hull and Glasgow (24). Analysed in Hull Laser Ablation Facility by Dempsey (24-25). Processed by Dempsey (25) The Trace element profiles of the magmatic grains, cathode luminescence imagery and the machine learning algorithm will be included upon completion. Raw data is in the form of .xls .seq and .io files which can be opened using the Iolite data processing software. The processed data is in the form of excel spread sheets with isochrons produced using Isoplotr. The contents of rows and columns in these datasets are labelled within the .xls file. The .xls files also include the operation conditions for the laser system and mass spectrometer.
