About Fluor-liddicoatite
Formula:
Ca(Li2Al)Al6(Si6O18)(BO3)3(OH)3F
Colour:
Light-brown, pink to red, green, blue, rarely white.
Lustre:
Vitreous
Hardness:
7½
Specific Gravity:
3.02
Crystal System:
Trigonal
Member of:
Name:
For being the F-analogue of liddicoatite.
Type Locality:
Note on the nomenclature: the "liddicoatite" holotype (Dunn et al., 1977) is F-dominant on the W-site, although the originally suggested formula was OH-dominant. Therefore the type material has been redefined as fluor-liddicoatite (Henry et al., 2011). Liddicoatite" was finally approved in 2025 using a neotype.
Most "liddicoatites" appear to be F-dominant, and therefore fluor-liddicoatite.
The "liddicoatite" of Nuber & Schmetzer (1981) is F-dominant according to the corresponding ICSD entry (the paper itself does not specify the accurate F content).
The Madagascar sample characterised in detail by Aurisicchio et al. (1999) is OH-dominant, and therefore liddicoatite, not fluor-liddicoatite.

Optical Data of Fluor-liddicoatite

Max. Birefringence:
δ = 0.016
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.

This shows the grain boundary and Becke line effect under plane-polarised
light, based on the contrast between this mineral's average refractive
index and the mounting medium. It does not take into account mineral
colouration.
In focus
Interference Figure:
This shows the idealized uniaxial interference figure - the conoscopic
(convergent-light, Bertrand-lens-in) view, for a grain cut with the optic axis
centred and vertical. The coloured rings are isochromatics, computed with the
same physics as the Michel-Lévy bar above; the dark cross is the isogyre.
For a genuinely uniaxial mineral viewed this way, that cross stays perfectly stationary if you rotate the stage - unlike a biaxial mineral, where it splits apart on rotation. That invariance is itself the standard diagnostic test for telling uniaxial and biaxial minerals apart at the microscope.
