Supplementary Figure: Plot of La, Tb and Co concentrations versus Th concentration, used
as a differentiation index. Data from Villemant �1979� are shown in grey. Arrows point to
the important changes due to crystal fractionation. 1st step: plagioclase, clinopyroxene and
olivine; 2nd step: plagioclase, clinopyroxene, hornblende, apatite and Fe‐Ti oxides. 3rd
step: biotite, alkali feldspar, apatite and Fe‐Ti oxides.
