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.

Albite is a very common mineral, and is an important rock-forming mineral. It takes a longer time for Albite to crystallize than the other feldspars. This enables Albite to form in large and well crystallized examples. Albite is also a common accessory mineral to …

Originally, Henry J. Brooke (1822) believed that most albite was either pale blue or pale red, but the most common colors of albite from today's perspective are white to colorless. Streak: White

albite, common feldspar mineral, a sodium aluminosilicate (NaAlSi 3 O 8) that occurs most widely in pegmatites and felsic igneous rocks such as granites. It may also be found in low-grade metamorphic rocks and as authigenic albite in certain sedimentary varieties.

2012年3月3日 · Albite 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 NaAlSi 3 O 8. It is a tectosilicate. Its color is usually pure white, hence its name from Latin albus.

Albite is a widely distributed white feldspar commonly found in granites, syenites, rhyolites, and trachytes, as well as pegmatites and spillites. Because albite is the last of the feldspars to crystallize from molten rock, it may often be found with other rare minerals.

Chemical Formula: NaAlSi 3 O 8 (Albite is the sodium end member of the plagioclase feldspars. Albite ranges from 90% to 100% NaAlSi 3 O 8 and 10% to 0%CaAl 2 Si 2 O 8 .) Color: White; sometimes, pale blue, pale gray, pale red, pale green or green
