APPENDIX B_Recalibrating the breakup history of SW Gondwana: U-Pb radioisotopic constraints from the southern Cape of South Africa

<div>Concordia plots for U-Pb radioisotopic data acquired by LA-ICPMS for samples from the Suurberg and Uitenhage Group.</div><div><br></div><div>The data were collected from 2015 to 2017.</div><div><br>LA-ICPMS: This was achieved using an <b>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. </b>All analyses were performed at the Central Analytical Facility at the University of Stellenbosch, South Africa. <div><br></div><div><br><br></div></div>
