Plagioclase Feldspar Data

Plagioclase is an alkalai feldspar that is one of several feldspar minerals, including sanidine, orthoclase, and microcline. There are several types of plagioclase feldspar which differ from one another based on variations in relative calcium and sodium content, including albite, oligoclase, andesine, labradorite, bytownite and anorthite.

The generic term "feldspar" comes from the Germanic term "feldt spat", meaning "mineral with prominent cleavage from the field". It was a prime constituent of many of the rocks over turned by farmers while plowing their fields. The feldspars are made up of three fundamental members and a wide number of chemical mixtures.
