Figure 10

Trace element and Sr isotope compositions of black gouge samples normalized to original values. Original values were estimated from mixing lines between samples FZ04 and FZ10, and Ti, Nb, and Nd concentrations of black gouge samples. Relative deviation (%) of each element concentration from the original value was calculated as follows: [(Concentration in black gouge − Original value)/Original value] × 100. Error bars indicate standard deviations from the data for Ryoke belt host rocks and are representative of the chemical heterogeneities of source rock compositions.
