Fig. 7From: Alteration and dehydration of subducting oceanic crust within subduction zones: implications for décollement step-down and plate-boundary seismogenesisVariations in %S values as a function of temperature with horizontal and vertical error bars of ±30 °C (Laughland and Underwood 1993) and ±5% (Hillier 1993), respectively. The diagram also shows variations in saponite content within sample MGLB as determined by Kameda et al. (2011a). The conversion reaction rate reported by Kameda et al. (2011c) is shown as a dotted gray line Back to article page
