Potassic-ferro-ferri-taramite from
Mohlileh Hill, Darkainle complex, Borama District, Awdal, Somaliland, Somalia


Locality type:Hill
Classification
Species:Potassic-ferro-ferri-taramite
Formula:K(CaNa)(Fe32+Fe23+)(Al2Si6O22)(OH)2
Comments:Potassi-ferro-ferri-taramite occurs as up to 10x4cm prismatic crystals in a mepheline syenite pegmatite. Brock et al. (1964) provide a wet chemical analysis with SiO2-37.13, TiO2-0,3, Al2O3-12.5, MnO-0.6, FeO-21.55, Fe2O3-11.14, MgO-0.83, CaO-7.54, Na2O-3.84, K2O-2.81, H2O-1.85. When normalized, this analysis give too high C3+ and too high A values. This may indicate analytical errors.
Quality for species:Excellent - world class for species or very significant. (!!)
Confirmation
Validity:Believed Valid
