Figure 2.10 A,B,C : Radiogenic isotope compositions plotted vs Th concentration which
is used as a differentiation index. AFC models for these systems are shown with
different values of the ratio between the assimilation and the crystallization mass: r�
0.06, r� 0.08, r� 0.10, r� 0.12 and r� 0.14. All parameters used for these calculations
are in Table 2.2.
