The thermal gradient models for the calculation of the temperature of each particle. The horizontal axis depicts the distance from the left side wall (c.a., moving backstop), whereas the vertical axis depicts the thermal gradient. The thermal gradient is linearly interpolated from the input sediments at 90 °C/km to the landward end at 50 °C/km in the final condition. The final thermal gradient model after 22,500 m of shortening (a). The thermal gradient model for different amounts of shortening, i.e., for 0 m (c.a., initial condition) (b), 9000 m (c), and 18,000 m (d)
