Méthode: Multiplions la formule par . On substitue alors un par un (une charge négative apparaît) ; on compense alors la charge électrique par un cation monovalent : feldspath potassique ou : albite. On substitue deux par deux (deux charges négatives apparaissent) ; on compense la charge électrique par un cation bivalent : anorthite.

The Plagioclase series is a group of related feldspar minerals that essentially have the same formula but vary in their percentage of sodium and calcium. Albite and Anorthite are the end members of the series, with the intermediary minerals Oligoclase, Andesine, Labradorite, and Bytownite. The acclaimed Dana's System of Mineralogy lists the intermediary members as …
