albiten.

Brit.

/ˈalbʌɪt/, U.S.

/ˈælˌbaɪt/

Origin: A borrowing from Latin, combined with an English element; modelled on a Swedish lexical item. Etymons: Latin albus , -ite suffix¹.

Etymology: < classical Latin albus white (see album n.²) + -ite suffix¹, after Swedish albit (J. G. Gahn & J. J. Berzelius 1815, in Afhandlingar i fysik, kemi och mineralogi 4 180).Occasional 19th-cent. examples of the form alvite probably originate in a misspelling or typographical error; compare:1831 tr. A. von Humboldt in Jrnl. Royal Inst. Great Brit. 1 418 With the auriferous sand are found grains of cinnabar, native copper, ceylanites, garnets, little white zircons as brilliant as diamonds, anatase, alvite [Fr. de l'albite], &c.

Mineralogy.

A sodium-rich plagioclase and an alkali feldspar, typically white or colourless, occurring widely in granitic rocks and also as prismatic crystals, often twinned.Albite is the sodium end member of the plagioclase and alkali feldspar series. Chemical formula: NaAlSi₃O₈. Crystal system: triclinic.

Compounds

albite felsite n. rare felsite whose chief component is albite.

ΚΠ

1868 J. D. Dana Syst. Mineral. (ed. 5) 351 Felsite or compact feldspar has usually some free silica disseminated through it. The following are analyses of some kinds, either albite-felsite or oligoclase-felsite.

1996 Appl. Geochem. 11 746/1 Albite felsite, generally composed of microcrystalline albite, occurred between the diabase sills and graphitic schist and graded to graphitic felsite and graphitic schist.

albite porphyry n. a porphyry containing crystals of albite.

ΚΠ

1868 J. D. Dana Syst. Mineral. (ed. 5) 352 In the compact condition, felsite, it constitutes the base of albite porphyry, a rock sometimes red (as at Agay) with scattered whitish crystals of albite.

1939 Geogr. Rev. 29 619 The dominant country rock is a soda granite. This is cut by..dikes of albite porphyry.

2010 P. Laznicka Giant Metallic Deposits (ed. 2) x. 409/2 At the Mount Charlotte Mine..a low-grade auriferous stockwork formed in the brittle granophyre unit of the GMD [= Golden Mile Dolerite] and in albite porphyry dikes.
