text: At the felsic end of the compositional range the differences are less marked, though cordierite granites retain systematically higher niobium, thorium, REE, titanium, and yttrium abundances than the leucogranites (Figure 5), and show systematic enrichment in zirconium and the LREE compared to the concentrations predicted by zircon and monazite solubility equations (Figure 12).
