Separation of the double seismic zone plotted against plate age. The separation of the double seismic zone obtained from a dynamic thermomechanical–petrological model is plotted against the age of the subducting slab. The distances from the middle of the oceanic crust to the level where fluids concentrate are shown by red and green dots. Vertical lines show error bars. Red and green dots are based on models of antigorite dehydration by Wunder and Schreyer (1997) and by Schmidt and Poli (1998), respectively. Blue dots are globally observed data reported by Brudzinski et al. (2007). (After Faccenda et al. 2012)
