About AnanditeHide

Ananda Kentish Coomaraswamy

Formula:

(Ba,K)(Fe²⁺,Mg)₃((Si,Al,Fe)₄O₁₀)(S,OH)₂

Colour:

Black

Lustre:

Sub-Vitreous, Resinous

Hardness:

3 - 4

Specific Gravity:

3.91 - 3.94

Crystal System:

Monoclinic

Member of:

Brittle Mica Group

Name:

Named in 1967 by D. B. Pattiaratchi, Esko Saari, and Thure Georg Sahama in honor of Ananda Kentish Coomaraswamy [August 22, 1877 Columbo, Sri Lanka (Ceylon)− September 9, 1947 Needham, Massachusetts, USA], briefly, the first director of the Mineral Survey of Ceylon. In 1906, he left geology, moved to New York City, New York, USA, and became a noted philosopher.

Type Locality:

ⓘ Wilagedera iron prospect, Kurunegala District, North Western Province, Sri Lanka

Mica Group.
An unusual sulphur-bearing member of the mica group with three known polytypes: anandite-2M1, anandite-1M, and anandite-2O (the most common polytype at the type locality). All anandite polytypes resemble each other, nearly opaque black mica.

Optical Data of AnanditeHide

Type:

Biaxial (+)

RI values:

n_α = 1.855 n_γ = 1.880

Birefringence:

0.025

Max. Birefringence:

δ = 0.025
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.

No measured or calculated 2V is on file for this mineral, so the value used here (91°) is estimated from its recorded refractive indices and optic sign, not from a direct 2V measurement.

Thickness: 30 µm

Stage rotation: 0°
