About Tetraferriannite
Formula:
KFe2+3(Si3Fe3+)O10(OH)2
Fe(III) may be replaced by minor Al.
Colour:
Brown to black
Lustre:
Adamantine, Vitreous
Hardness:
2½ - 3
Crystal System:
Monoclinic
Member of:
Name:
In allusion to its composition and crystal structure, containing iron 3+ cations (FERRIc, from Latin ferrum = 'iron') in TETRAhedrally coordinated sites, and its chemical relationship to annite. The original name, ferri-annite, was changed by the CNMMN in 1998 to tetra-ferri-annite. The hyphens were removed by the IMA in 2008, resulting in tetraferriannite.

Max. Birefringence:
δ = 0.068
Based on recorded range of RI values above.
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. Each grain retains its interference colour (retardation) while its brightness falls to black at extinction and reaches a maximum between extinction positions.
