Concordia plots for U-Pb radioisotopic data acquired by LA-ICPMS for samples from the Suurberg and Uitenhage Group.
The data were collected from 2015 to 2017.
LA-ICPMS: This was achieved using an ASI
Resolution M-50-LR Excimer laser to ablate zircon grains within a
Laurin Technic M-50 dual-volume cell, both coupled to a Thermo
Scientific Element 2 single collector mass spectrometer. All analyses were performed at the Central Analytical Facility at the University of Stellenbosch, South Africa.
