About Ferri-fluoro-leakeiteHide

Bernard Elgey Leake

Formula:

NaNa₂(Mg₂Fe³⁺₂Li)(Si₈O₂₂)F₂

The Leakeite group minerals are sodium amphiboles defined with:
^A(Na+K+2Ca)> 0.5 apfu,
^C(Al+Fe³⁺+2Ti) > 1.5 apfu and
^CLi > 0,5 apfu

Ferri-fluoro-leakeite is defined with
A position: Na dominant
C²⁺ position: Mg dominant
C³⁺ position: Fe dominant
W position: F dominant

Colour:

Black; mustard yellow to brownish yellow

Lustre:

Vitreous

Hardness:

Specific Gravity:

3.245 (Calculated)

Crystal System:

Monoclinic

Member of:

Leakeite Root Name Group > Sodium Amphibole Subgroup > w(OH,F,Cl)-dominant Amphibole Group > Amphibole Supergroup

Name:

The root name leakite is in honor of Scottish geologist Bernard Elgey Leake [1932-], University of Glasgow and who was chairman of the IMA subcommitte to revise amphibole nomenclature. The chemical prefixes designates the chemical relationship in the group.

Type Locality:

ⓘ Verkhnee Espe Massif (Verkhnee Espe deposit), Akzhaylyautas Mts (Akzhailyautas Mts; Akjaylautas Mts; Akzhalautas Mts), Tarbagatai Range, Abai Region, Kazakhstan

The mineral originally described as fluoroleakeite by Cámara et al. (2010) are now named ferri-fluoro-leakeite as the leakeite group was redefined in the 2012 amphibole nomenclature.

The name fluoro-leakeite is now used for the Na, Mg, Al and F dominant member of the group, which was originally named fluoro-aluminoleakeite by Roberti et al. (2009).

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.

Thickness: 30 µm Order divisions

Surface Relief:

Moderate

Optical Extinction:

X ∧ a = 14.1º (in β obtuse); Y = b; Z ∧ c = 75.9º (in β acute).
