Member of:

Chlorite Group

Name:

Named by M.V. Seredin et al. in 2003 in honor of Alexander Andreevich Glagolev (Александр Андреевич Глаголев) (1927-1993), Russian mineralogist and petrographer known for his work on the ultramafic-alkaline rocks and carbonatites such as at Kovdor, Russia.

Type Locality:

ⓘ Kovdor Phlogopite mine, Kovdor Massif, Kovdorsky District, Murmansk Oblast, Russia

The first mineral of the chlorite group that contains Na atoms located between 2:1 layers and the interlayer octahedral sheets.

Chemically similar to dravite.

Optical Data of GlagoleviteHide

Type:

Biaxial (+)

RI values:

n_α = 1.569(2) n_β = 1.569(2) n_γ = 1.571(2)

2V:

Measured: 17° (3)

Max. Birefringence:

δ = 0.002
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:

Moderate (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°
