From: Subduction of fracture zones controls mantle melting and geochemical signature above slabs
(a) Numerical experiment with a heterogeneous subducting plate (20–30 Ma). (b) Numerical experiment with a heterogeneous subducting plate (20–30 Ma) and partially serpentinized fracture zone (hserp. f.z.=10 km; ρserp. f.z.=2,800 kg m−3). Green strip in the middle of the oceanic plate represents the serpentinized fracture zone, and partially molten mantle above the slab is coloured according to the temperature. Dashed line represents the base of the continental lithosphere.
