Temperature structure around slab edges. (a) The case with a retreating trench (VAS = -7.5 cm/yr, VBS = 0 cm/yr). (b) The case with a fixed trench (VAS = 0 cm/yr, VBS = 7.5 cm/yr). (c) The case with an advancing trench (VAS = -7.5 cm/yr, VBS = 15.0 cm/yr). The cyan plane shows an isothermal surface of 1000°C. Yellow lines shows the isotherms of 400, 800, and 1200°C on the plane with θ = 94.5°. Time shown in the bottom-left corner of each figure is the time elapsed from the start of each calculation.
