Figure 8

The average Rb-Sr contents and 87Rb/86Sr ratios of each sample are compared with the XRD data. (A) 87Rb/86Sr vs interstratified ratio (IR) of I/S. IR is the percentage of smectite layers in I/S; (B) potassium (K) content vs IR of I/S; (C) Rb content vs K content; (D) Rb content vs IR of I/S; (E) Sr content vs IR of I/S.
