87		Subduction model with LVC and LVW - temperature field. The initial thermal structure consists of a 50 Ma old oceanic plate (left side) and a 100 Ma old continental plate. The convergence rate is 5 cm/yr and the continental plate is fixed.	VIEW
86		Subduction model with LVC and LVW - viscosity field. The initial thermal structure consists of a 50 Ma old oceanic plate (left side) and a 100 Ma old continental plate. The convergence rate is 5 cm/yr and the continental plate is fixed. The viscosity in the wedge and channel is 20x reduced compared with the asthenosphere. The LVC starts at 20 km depth whereas the LVW starts at 40 km depth and goes down to 300 km depth.	VIEW
83		From Flat slab to Steep slab - Temperature: we allow a LVC to develop (in time) between the oceanic plate and the overriding continental plate. This will decouple the two plates reducing the suction force and therefore allowing the sunducting plate to fall into the asthenosphere at steeper angles. Note how the weakening of the base of the continental lithosphere allows hot ashtenospheric material to flow into the developing mantle wedge.	VIEW
