Note Hoshino et al. (2008) have investigated the composition of dissakisite-(Ce) and allanite-(Ce) from this locality, and also publish 10 microprobe analyses from a single crystal. Their conclusion is that: Euhedral dissakisites from Trimouns dolomite mine, France, is compositionally-zoned. Back-scattered electron (BSE) images reveal that each of the described dissakisite crystals has three distinct compositional zones: normal zoned core (Mg-rich), oscillatory zoned middle (Ca-Al-rich) and homogeneous rim (Fe-ΣREE-rich). The latter zone with Fe2+> Mg corresponds to allanite-(Ce). Dissakisite-(Ce) also displays pronounced zoning in Fe/Mg which may suggest that the temperature of crystallization continuously decreased from core to rim. Each individual crystal will probably therefore contain both species. Allanite-(Ce) is generally considered to be darker than dissakisite-(Ce), but this is not a definitive way to distinguish between the minerals.
