About Allanite
Formula:
{A12+REE3+}{M3+2M32+}(Si2O7)(SiO4)O(OH)
Name:
Named in 1810 by Thomas Thomson for Thomas Allan (1777-1833), Scottish mineralogist, who first observed the mineral.
Individual REE members were later distinguished by adding the -(Ce), -(La) etc. suffix.

Fe-rich varieties may be confused with ferriallanite-(Ce) and Ferriallanite-(La), or other blackish members of the epidote supergroup.
In the older literature the name "orthite" was often used instead of allanite.
