Figure 1.
Cartoon showing a conceptual model of the structure and metamorphic evolution of subducting lithosphere formed at a fast spreading center (from Ranero et al., 2005). The topography of the plate in the outer-rise/trench region has been exaggerated to better show the deformation associated with plate bending. Scale is otherwise approximately correct. Fault plane solutions of earthquakes are projected into the top of the slab and the plane of the cross section. The small black-filled circles in oceanic crust indicate hydration.
