Seidozeritovyi pegmatite no. 1, Suoluaiv Mountain, Lovozersky District, Murmansk Oblast, Russia

Largest Crystal Size: 5 mm

Analyzed 5x3 mm crystal of Fluorflogopite - the first find of the mineral in Lovozero massif. Empirical formula of the mineral with unusually high fluorine content (up to 11.15 mas.%) is (K0.80Na0.08)0.88(Mg2.66Al0.16Fe0.10Ti0.05Mn0.02)2.99(Si3.60Al0.40)4.00O10.36F2.00. Below well formed brown prismatic crystal of Seidozerite presents. Associating minerals are K-feldspar, green Aegirine and chalky-white aggregates of unidentified zeolites. Collected in Summer of 2010. Pavel M. Kartashov analytical data, collection and photo.

Dimensions: 5 cm x 3 cm x 2.5 cm

Brownish tabular crystals of Fluorphlogopite are disseminated over the specimen (at least 8 on this side). This is the first find of the mineral in Lovozero massif. Empirical formula of the mineral with unusually high fluorine content (up to 11.15 mas.%) is (K0.80Na0.08)0.88(Mg2.66Al0.16Fe0.10Ti0.05Mn0.02)2.99(Si3.60Al0.40)4.00O10.36F2.00. Well formed brown prismatic crystals of Seidozerite also presents. Associating minerals are K-feldspar, green Aegirine and chalky-white aggregates of unidentified zeolites. Specimen size is 5x3x2.5 cm. Collected in Summer of 2010. Pavel M. Kartashov analytical data, collection and photo.
