  • Chemical Composition Plagioclase Feldspar

    Chemical Composition Plagioclase Feldspar

    Chemical Composition. Albite is at one end of the series and Anorthite at the other. Ca2+ can substitute for Na+ because they are similar in size and charge neutrality is maintained by substituting Al3+ for Si4+. Composition of Plagioclase is described in terms of Anorthite with An + Ab = 100. The solid solution equilibrium equation can be written as.

    Feldspars vary in color from pink to gray, and are categorized by the additives they contain. Pure potassium feldspar is orthoclase (KAlSi 3 O 8), pure sodium feldspar is albite (NaAlSi 3 O 8), and pure calcium feldspar is anorthite (CaAl 2 Si 3 O 8). A feldspar may contain both sodium and calcium or sodium and potassium.
