About AnorthiteHide

This section is currently hidden. Click the show button to view.

Formula:

Ca(Al₂Si₂O₈)

Colour:

Colourless, reddish grey, white

Lustre:

Vitreous

Hardness:

6 - 6½

Specific Gravity:

2.74 - 2.76

Crystal System:

Triclinic

Member of:

Plagioclase Group > Feldspar Group

Name:

Named in 1823 by Gustav Rose from the Greek αν and oρθός, "not right angle" or "oblique", in allusion to the oblique triclinic form of the crystals.

Type Locality:

ⓘ Mount Somma, Metropolitan City of Naples, Campania, Italy

Polymorph of:

Dmisteinbergite, Stöfflerite, Svyatoslavite

Feldspar Group.

Ca-rich end member of the plagioclase (Albite-Anorthite Series).

High- and low-temperature structural modifications exist.

Chemically and stoichiometrically very similar to lawsonite (which contains OH groups and H₂O molecules, however).

Type:

Biaxial (-)

RI values:

n_α = 1.573 - 1.577 n_β = 1.58 - 1.585 n_γ = 1.585 - 1.59

2V:

Measured: 78° to 83°, Calculated: 78°

Max. Birefringence:

δ = 0.012 - 0.013
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.

Thickness: 30 µm

Barium-Anorthite (of Nockolds and Zies)	A Ba-bearing anorthite with 3.5% BaO. Originally described from Broken Hill, Yancowinna Co., New South Wales, Australia.
Bytownite	A plagioclase feldspar with an albite : anorthite molar ratio ranging from 10 : 90 to 30 : 70. May show labradorescence (compare labradorite). The original material, a greenish-white substance, was found in a boulder near Bytown (now Ottawa), and later...
Labradorite	A plagioclase feldspar with an albite : anorthite molar ratio ranging from 30 : 70 to 50 : 50. An intermediate member of the Albite-Anorthite Series. Labradorite can display an iridescent optical effect (or schiller) known as labradorescence. The cause ...
Lindsayite	An altered anorthite.
Lynx Eye	Variety of labradorite with green iridescence.
Oregon Sunstone	Sunstone with inclusions of copper instead of hematite. Crystallographically oriented nanocrystals of protoenstatite and clinoenstatite in association with copper nanocrystals are responsible for the unusual green and “watermelon” coloration of the Or...
Spectrolite	A variety of labradorite (strictly, anorthite) showing strong labradorescence due to very fine exsolution of K-feldspar.
