Crystal on matrix of Dolomite of the isomorphous series Dissakisite-(Ce)/Allanite-(Ce)
The majority of Trimouns specimens present color zoning that seems to indicate the presence of both species in the same crystal, the darkest areas corresponding to Allanite-(Ce), as they are richer in iron, and the dominant lighter areas to Dissakisite-(Ce)
