From: Alteration and dehydration of subducting oceanic crust within subduction zones: implications for décollement step-down and plate-boundary seismogenesis

Fig. 8

Model showing a the setting for décollement step-down at the plate interface, and b the textural evolution from intact basalt to mature fault rock (ultracataclasite) as observed in onland exposures. The diagram also shows expected frictional properties and behaviors associated with seismogenesis. Abbreviations are as in Fig. 2
