Member of:

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

Name:

This mineral was first published as leakeite (Hawthorne et.al). The Leakeite group minerals was redefined in the 2012 amphibole nomenclature. The mineral described by Hawthorne et.al (1992) is now named ferri-leakeite. The series root name was named in 1992 by Frank Christopher Hawthorne, Roberta Oberti, Luciano Ungaretti, and Joel Dennison Grice in honor of Scottish geologist Bernard Elgey Leake [1932-], University of Glasgow and who was chairman of the IMA subcommittee to revise amphibole nomenclature. The chemical suffix designates the chemical relationship in the series.

Optical Data of Ferri-leakeiteHide

Type:

Biaxial (-)

RI values:

n_α = 1.667(1) n_β = 1.675(1) n_γ = 1.691(1)

2V:

Measured: 59° to 71°, Calculated: 72°

Max. Birefringence:

δ = 0.024
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

Rotation:

Surface Relief:

Very High (positive)
Relative to Canada balsam mounting medium (n ≈ 1.537).

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.

Focus:

In focus

Interference Figure:

This shows the idealized biaxial acute bisectrix (Bxa) interference figure - the conoscopic view for a grain cut perpendicular to the acute bisectrix, using this mineral's 2V. The two small white dots mark the melatopes - the points where the two optic axes emerge - and are shown only when they fall within the field of view. The coloured bands are isochromatics, and the dark bands are isogyres.

Rotate the stage: at 0°/90° the isogyres form a cross through the melatopes; at 45° they pull apart into curved hyperbolas. That splitting on rotation - absent in a uniaxial figure - is the standard diagnostic test for telling biaxial minerals from uniaxial ones. If 2V is large, the melatopes may fall outside the field of view, as they often do at the microscope too.

Thickness: 30 µm

Stage rotation: 0°

Dispersion:

r > v or r < v

Pleochroism:

Strong

Comments:
