mineral albite and where it 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: Albite mineral information and data. - MindatFeldspar Group . Na-rich end member of the Albite-Anorthite Series .
