The Sámi flag
Formula:
Ba◻Na3Ti2Nb(Si2O7)2O2(OH)F(H2O)2
Colour:
Colorless to very pale tan
Lustre:
Vitreous
Hardness:
3
Specific Gravity:
3.243 (Calculated)
Crystal System:
Triclinic
Name:
Named after the Saami (Саами in Cyrillic) indigenous people who inhabit parts of the Kola Peninsula of Russia, far northern Norway, Sweden, and Finland.
Chemically and topologically related to kazanskyite, nechelyustovite and bornemanite. Also chemically similar to bykovaite and tazzoliite.
Not to be confused with Saamite (of Volkova & Melentiev).

Group-III TS-block Ti-disilicate, that is, contains TS block built of HOH layers (H = heteropolyhedral layer, O = octahedral layer), and Ti+Nb+Mg = 3 apfu.

Crystal structure details:
The O sheet: Na- and Ti-dominant octahedra, Na3Ti ideal composition.
H sheets: with disilicate groups link to polyhedra with (1) [5]Ti and (2)[6]Nb.
Two peripheral sites: (1) [10]AP(1), (Ba,Sr,K), 94% occupancy, and (2) [8]AP(2), Ca, 26% occupancy.
Adjacent TS blocks connect via (1) hydrogen bonds, water-water and H2O–O (2) via a layer of Ba atoms that form the I (intermediate) block.

Optical Data of SaamiteHide

Type:
Biaxial (+)
RI values:
nα = 1.760 nβ = 1.770 nγ = 1.795
2V:
Measured: 69° (2), Calculated: 65°
Max. Birefringence:
δ = 0.035
Based on recorded range of RI values above.

Interference Colours:
The colours simulate birefringence patterns seen in thin section under crossed polars. They do not take into account mineral colouration or opacity.

Michel-Levy Bar The default colours simulate the birefringence range for a 30 µm thin-section thickness. Adjust the slider to simulate a different thickness.

Grain Simulation You can rotate the grain simulation to show how this range might look as you rotated a sample under crossed polars.
