Allanite Group from
In den Dellen quarries, Mendig, Mendig, Mayen-Koblenz, Rhineland-Palatinate, Germany
| Locality type: | Quarry | |
| Classification | ||
|---|---|---|
| Species: | 'Allanite Group' (not an IMA approved species) | |
| Formula: | (A12+REE3+)(M13+M23+M32+)O[Si2O7][SiO4](OH) | |
| Comments: | The allanite group minerals are difficult identify. Not only do the crystals resemble pyroxenes and amphiboles, but several species in the allanite group have been identified . The Ce ratio is variable, giving allanite-(Ce) and allanite-(La) as well as ferriallanite-(Ce) and ferriallanite-(La). It appears that the larger, tabular crystals are mostly allanite-(Ce), but insufficient specimens have been analyzed to determine whether there is a relationship between composition, paragenesis and crystal form. | |
