[1] Mantle dynamics can strongly affect melting processes beneath spreading centers and volcanic arcs. A 2-D numerical model of the Tonga subduction zone, with the slab viscously coupled to the mantle beneath the brittleductile transition but faulted above, shows that induced corner flow may cause asymmetric melting at the Lau backarc spreading center, 400 km away. The down-going slab also entrains the high-viscosity base of the overlying lithosphere, drawing hot, low-viscosity asthenosphere… CONTINUE READING
