Name:
Named in honor of Vladimir Georgievich Feklichev (Владимир Георгиевич Фекличев) (30 June 1933 - 1999), Russian petrologist, mineralogist and crystallographer.
Eudialyte Group.

Distinguished from eudialyte sensu stricto by ordering of Ca (at M1 and Na4 sites), dominance of ferric iron and niobium (at M3 site, located in the centre of ninefold ring). Other group members with essential Fe3+ are fengchengite, ikranite, and mogovidite. Chemically similar minerals are ferrokentbrooksite, golyshevite, and raslakite (the last Cl-rich).

An interesting feature is presence of some Mn at Si sites.

Optical Data of FeklicheviteHide

This section is currently hidden. Click the show button to view.
Type:
Uniaxial (-)
RI values:
nω = 1.620 nε = 1.616
Max. Birefringence:
δ = 0.004
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.

Surface Relief:
Moderate
Pleochroism:
Non-pleochroic
