APPENDIX A (Data Tables)_Recalibrating the breakup history of SW Gondwana: U-Pb radioisotopic constraints from the southern Cape of South Africa

U-Pb radioisotopic data for the Suurberg and Uitenhage Groups acquired by ICPMS and TIMS.<br>The data were collected from 2015 to 2017. There are two types of data acquired from two different mass spectrometers, (1) LA-ICPMS and (2) CA-TIMS: <br> (1) 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. <br><br>(2) CA-TIMS: Following chemical abrasion pre-treatments, analysis was performed on a <b>Micromass Sector54 thermal-ionisation mass spectrometer</b> at the Berkeley Geochronology Center in California, USA.
