Thermochronometric modelling predictions for model of non-inverted, thermally-relaxed rifted margins (Model B; Fig. 2). (A) Model thermochronological ages for the four low-temperature thermochronometers considered in this study. Age patterns predicted for Model A (Fig. 3) are plotted in grey in (A) for comparison. (B) Predicted chlorine content-dependent apatite and annealing model-dependent zircon mean track length data (MTL) plotted against model ages. (C) Individual particles’ model time-temperature paths extracted from Model B (Fig. 2). Coloured dashed lines in (C) represent the portions of the particles’ time-temperature paths that have changed between Model A (inversion) and Model B (no inversion, pure postrift thermal relaxation). Brown bars indicate the ages of extension in Model B. See Figure 3 for details.
