Crystallography of AlbiteHide

Crystal System:
Triclinic
Class (H-M):
1 - Pinacoidal
Cell Parameters:
a = 8.16 Å, b = 12.87 Å, c = 7.11 Å
α = 93.45°, β = 116.4°, γ = 90.28°
Ratio:
a:b:c = 0.634 : 1 : 0.552
Unit Cell V:
667.19 ų (Calculated from Unit Cell)
Z:

Morphology:
Crystals commonly tabular parallel {010} (thin plates to blocky crystals), may be curved, to 3 cm; divergent aggregates, granular, cleavable massive.
Twinning:
Common around [010] or perpendicular {010}, giving polysynthetic striae on 001 or {010}; many other laws, contact, simple and multiple.
Comment:
High and low forms; both are described in the non-standard space-group C-1 (chosen by convention to facilitate comparison with C-centred monoclinic orthoclase and sanidine). The reduced cell is: a = 7.158, b = 7.438, c = 7.713 Å, α = 115.068, β = 107.321, γ = 100.431° (cell from Armbruster et al., 1990).

Varieties of AlbiteHide

Albite Moonstone
AndesineA plagioclase feldspar with an albite : anorthite molar ratio ranging from 50 : 50 to 70 : 30.

Originally described from Marmato Mine, Marmato, Cauca, Chocó Department, Colombia.
Crystals rare, to 2 cm; commonly massive, cleavable, or granular. Twi...
CleavelanditePlaty albite, generally found in pegmatite.
High AlbiteStable above 800°C - usually formed in hydrothermal syntheses, has disordered Al-Si arrangement (in contrast to 'low albite').
Lazur-FeldspathA blue feldspar found with Lapis Lazuli near Lake Baikal, Russia
Low AlbiteStable below 700°C with an ordered Si-Al arrangement, in contrast to 'high albite'.
OligoclaseA plagioclase feldspar with an albite : anorthite molar ratio ranging from 90 : 10 to 70 : 30.

Originally described from Danvikstull, Stockholm, Södermanland, Sweden.
Oligoclase-AlbiteA variety of Oligoclase with Anorthite:Albite between 80:20 and 90:10. Now regarded as a superflous subdivision of Oligoclase. [Clark, 1993 - "Hey's Mineral Index"]
Originally described from Dypingdal Serpentine-magnesite deposit, Snarum, Modum, Buskeru...
PericlineA variety of albite occurring as milky-white, elongated (along the b-axis) crystals, generally in alpinotype clefts.
Interestingly, Breithaupt (1823) defines the morphology originally as tabular.
PeristeriteA variety of albite showing slight iridescence and sometimes adularescence (as in moonstone).
Sodic AlbiteAn albite with an albite:anorthite ratio of less than 5:95.
ZygaditeZygadite variety of albite consists of an unusual crystallographic habit: tabular crystals with a steeply acute morphology.
