<p>Supplementary data to accompany Gernon, T.M., Hincks, T.K., Brune, S., Braun, J., Jones, S.M., Keir, D., Cunningham, A., & Glerum, A., <em>Co-evolution of craton margins and interiors during continental breakup</em>. Nature (Accepted in Principle at time of writing, 3 June 2024).</p> <p><strong>Constraining thermochron uncertainty</strong></p> <p>We utilise published thermochron model data for 46 sites across southern Africa from Brown et al. (2002); Green et al. (2017); Kounov et al. (2013) and (2009); Stanley et al. (2020), (2015) and (2013); Tinker et al. (2008), and Wildman et al. (2017), (2016) and (2015). </p> <p>The above studies present model uncertainty in slightly different ways. However, we have attempted to provide equivalent estimates of uncertainty across the board in our analysis. </p> <p>Stanley and Flowers (2020) provide individual simulation runs for 15 sites, and we use these directly to estimate maximum temperature drop and associated timing for each simulation. For the 12 sites provided by Wildman et al. (2017, 2016, 2015), we use the best fit and 95 percentile envelope, and assume the 'good fit' envelopes of Kounov et al. (2009) to be broadly equivalent. For 15 sites (see MinMax.csv) we utilise the best fit curve together with an estimate of the minimum and maximum plausible timing of the point of maximum temperature drop.</p> <p>Green et al. (2017) provides only a best fit curve, and in the absence of further data we cannot provide an uncertainty estimate here. </p> <p><br><strong>Files provided</strong></p> <p><strong>SourceData.csv</strong><br>Summary of each site, associated data source(s), coordinates and model uncertainty. Please see references listed within for complete thermochron model descriptions and original data.</p> <p><strong>MinMax.csv</strong><br>Name/Location and references for thermochron source data for 15 sites with best fit curves, and estimates of the min/max time of maximum temperature drop.<br>Tmin and Tmax (degrees C) are the minimum and maximum modelled temperatures for each location. t1_Ma and t2_Ma are the minimum and maximum times (Ma) where the model simulations (best, good or acceptable fit) reach the midpoint temperature Tmid= (Tmax -Tmin)/2<br>The most likely timing is taken from the best fit curve. </p> <p><strong>Files in Thermochron_bestfit</strong><br>Best fit thermochron curves (Age in Ma, and Temp in degrees C) for 31 sites digitized from the original publications. Names correspond to File Names in SourceData.csv, which also provides references.</p> <p><strong>Files in Thermochron_Envelopes</strong><br>Lower and Upper 95 percentile thermochron envelopes (denoted *_L95.csv or *_U95.csv) for 12 sites, digitized from Wildman et al.
