Figure 3

Time series showing modeling results with dual thermal anomalies of 10, 15 and 20 km in diameter and a ΔT = 100 °C, 140 °C, and 200 °C and extensional background strain rates of 1.585–4.756–7.927 × 10^–16 s⁻¹. Time snapshots marked with a gray background depict the moment of the secondary thermal anomaly addition. The secondary thermal anomaly has the same properties as the initially set up. All models are integrated 1 Myr in time.
