About Amazonite
Formula:
K(AlSi3O8)
Name:
Named in 1847 by Johann Friedrich August Breithaupt for an unspecified type locality area "near" the Amazon River.
A variety of Microcline
A green to blue-green variety of K-feldspar, usually microcline, but sometimes applied to orthoclase.
The color is usually caused by an elevated content of Pb (up to 1.2% PbO, see list of references).
However, there are also indications that the green color of some microcline is caused by divalent Fe (Szuzkiewicz & Körber, 2010). Overenthusiastic uses of this name include giving this name to slightly gray-green hues in microcline that are often photosensitive and turn from greenish gray to light smoky gray. Sunlight can sometimes enrich the color of genuine amazonite.
