Andesine

Andesine labradorite is considered as no longer as a separate mineral, but is a mineral mixture of albite and anorthite from the group of the feldspars and the mineral class of silicates. Andesine is a rock forming silicate framework with the general empirical formula (Na, Ca) Al (Si, Al) 3o8, which crystallizes in the triclinic crystal system and developed predominantly massive aggregates.

Andesine was named after its first location, the South American Andes.

Definition

Andesine, together with albite, oligoclase, labradorite, and anorthite Bytownite the perfect mixed batch of plagioclase. Plagioclase with a content of 30 to 50 mole % of anorthite ( AN30 to An50 ) are referred to as andesine.

Varieties

• Belomorit - pink - white color, bluish iridescent.

Education and Locations

Andesine forms magmatic in andesites, granodiorites and diorites. It also comes metamorphic gneisses and migmatites in front.

Locations include ground corn in Germany, the Esterel and the Massif Central in France, in Italy Adamello and the Andes in South America.
