differ signiÞcantly in Al oxide concentrations, because the sesquioxides of rareearths replace Al ions from mineral lattice and substitute them with whole hosts of actinides and lanthanides, as evident from Figs. 1 a and 2. This is possible because the lanthanides and actinides are strong phosphate mineral formers and are difÞcult to hydrolyse.
