|
|
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)
Mineral: | Dissakisite-(Ce)/Allanite-(Ce) with Dolomite |
Locality: | Trimouns Mine, Luzenac, Ariège, Occitanie, France |  |

|
|
Druse on matrix of bipyramidal Creedite crystals, some of them doubly terminated, with sharp pointed terminations.
The specimen is quite different from those known from this locality in recent years, although in some old collections there are similar specimens from the same source, which coincides with the indications that this find was made in old galleries of the mine.
Mineral: | Creedite |
Locality: | Navidad Mine, Abasolo, Rodeo, Municipio de Rodeo, Durango, Mexico |  |
