Albite - Wikipedia

Albite is a plagioclase feldspar mineral. It is the sodium endmember of the plagioclase solid solution series. It represents a plagioclase with less than 10% anorthite content. The pure albite endmember has the formula NaAlSi 3O 8. It is a tectosilicate. Its color is usually pure white, hence its name from Latin, albus.
