Figure 6. Binary plot of log (Rb concentration) vs log (Ta+Yb concentration) which Pearce et al. (1984) use to distinguish among granitic rocks. The bold lines dividing fields are those determined by Pearce et al. (1984). The lighter lines represent the same concentrations + or - one average standard deviation for the measurements. Boxes = black shales, n = 206.
