Alkali feldspars: ordering, composition and optical properties
For the entire alkali feldspar series, Σt₁ (total Al content in the T₁ sites, a quantitative measure of structural state or Al,Si long-range ordering) can be closely estimated from X<sub>Or</sub> (mole fraction of KAlSi₃O₈) and Y<sub>x</sub> (one half of the optic axial angle...
