  • n. A mineral of the feldspar family, triclinic in crystallization, and in composition a silicate of alumina and soda. It is a common constituent of granite and of various igneous rocks. See feldspar.

from The Century Dictionary and Cyclopedia

  • n. A triclinic soda feldspar; a common mineral, usually white or nearly white, occurring in crystals and in cleavable masses in granite veins, also as a constituent of many crystalline rocks, as diorite and some kinds of granite. See feldspar.

Etymologies

Latin albus, white; see albho- in Indo-European roots + -ite1.
(American Heritage® Dictionary of the English Language, Fourth Edition)
From the Latin albus (white), the common color of the mineral. (Wiktionary)

Examples

  • Sodium occurs abundantly as nitrate (NaNO_ {3}) in Chili saltpetre, and as silicate in various minerals, such as albite (or soda-felspar).

    A Text-book of Assaying: For the Use of Those Connected with Mines.

  • They've grown on a spectacular backdrop matrix of gem quartz, purple lepidolite and white albite blades.

    In Pictures: Highlights Of Marc Weill's Mineral Collection

  • Basically, a process called metamorphism caused the basalts in Shenandoah to recrystallize with new minerals, such as chlorite, epidote, and albite, which help give the rocks their greenish hue.

    The Killing Hour

  • In chemical composition and in optical and other physical characters it is thus much nearer to the anorthite end of the series than to albite.

  • It depends on the felspar present -- _i. e._, whether it is orthoclase, oligoclase, or albite -- whether the soil will be rich in potash or not.

    Manures and the principles of manuring

  • The best specimens are afforded by the beautifully developed transparent glassy crystals, found with albite, prehnite and quartz, in a zone of amphibolite and chlorite-schists at Le Bourg d'Oisans in Dauphin├ę.

    Encyclopaedia Britannica, 11th Edition, Volume 3, Part 1, Slice 1 "Austria, Lower" to "Bacon"

  • They are divisible into two great classes, which have received the names of diorite and dolerite, the former a mixture of albite and hornblende, the latter of augite and labradorite, sometimes with considerable quantities of a sort of oligoclase containing both soda and lime, and of different kinds of zeolitic minerals.

    Elements of Agricultural Chemistry

  • Those yielded by orthoclase must generally abound in potash, while albite and labradorite, containing little or none of that element, must produce soils in which it is deficient.

    Elements of Agricultural Chemistry

  • The albite which the former contains undergoes a rapid decomposition, and yields abundance of soda along with some potash, which is seldom altogether wanting, while the hornblende supplies both lime and magnesia.

    Elements of Agricultural Chemistry

  • There are, for instance, several different minerals commonly classified under the name of felspar, which have been distinguished by mineralogists by the names of orthoclase, albite, oligoclase, and labradorite; and there are at least two sorts of mica, two of hornblende, and many varieties of zeolites.
