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.

Named in 1815 by Johan Gottlieb Gahn and Jöns Jacob Berzelius from Latin "albus", white, alluding to its usual color. One of the most common members of the Feldspar group. Low- and high-temperature structural modifications exist (' low albite ' and ' high albite '), with ordered and disordered Al-Si distribution, respectively.

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 …

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.

2023年10月15日 · Albite is characteristic of low-grade regional and contact metamorphic rocks (greenschist, zeolite, and albite-epidote hornfels facies). It is generally the last of the feldspars to crystalize in igneous rocks. Albite commonly occurs in …

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.

Albite is the last of the plagioclase feldspars to crystallize. It can also forms in hydrothermal veins (near volcanoes). Common mineral associations: Hornblende, Biotite, Muscovite. Associated...

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.

Albite is a translucent to transparent gemstone belonging to the feldspar mineral family, known for its white to colorless appearance and moderate hardness. Discover the world of albite, a feldspar mineral that transcends ages to reveal a stunning array of …
