Albite: The plagioclase feldspar mineral Albite information & picturesAlbite is a very common mineral, but localities where fine Albite crystals can be found are more limited. Some excellent examples have come from the Swiss Alps and the Tyrol, Austria. Large, well formed crystals come from the pegmatites of Gilgit, Pakistan; and Nuristan, Afghanistan. Enormous Clevelandite crystals have.mineral albite and where it is mined,Albite - WikipediaAlbite is a plagioclase feldspar mineral. It is the sodium endmember of the plagioclase solid solution series. As such it represents a plagioclase with less than 10% anorthite content. The pure albite endmember has the formula NaAlSi3O8. It is a tectosilicate. Its color is usually pure white, hence its name from Latin albus.

Albite a widely distributed and important rock-making mineral. It occurs in all classes of rocks, but particularly in those of igneous origin, such as granites, syenites, porphyries arid felsite lavas. Found commonly, also, in pegmatite veins. Albite weathers to kaolin and mica (paragonite) mixed with quartz and calcite in the more.

Albite | Mineralogy4Kids

A member of the plagioclase feldspar group and the Na-rich end member of the albite-anorthite series, this mineral is one of the rock-forming minerals. It is found in felsic plutonic rocks. Its name comes from the Latin word meaning "white," alluding to its usual color. As with all plagioclase feldspars, this mineral will display.

These pegmatites have quartz cores surrounded by coarse-grained microcline perthite, an alkali feldspar typically composed of 60–75% K-spar. They account for almost all of the 18 457 t of feldspar produced by selective mining of 21 individual pegmatites from 1932 to 1979. Poorly zoned albite-bearing pegmatite bodies,.

found. Although plagioclase feldspar is an abundant rock- forming mineral, localities where well-developed euhedral crystals occur are rare, especially in Britain, and many former localities are no longer available. There are exceptions. In Britain, albite in fine but small crystals occurs in the granites of the Mourne Mountains.
