  • KFeldspar and Plagioclase Feldspar

    Feldspars have two cleavage planes that intersect at 90°. Fragments of pure feldspar crystals thus tend to form rectangular blocks with irregular ends. Feldspars have vitreous lusters and occur in opaque shades of white to gray to pink to very dark gray.

  • Feldspar minerals make up over 50% of Earth's crust.

    The Plagioclase Feldspars. Albite and anorthite have an interesting relationship. Albite is a sodium feldspar, and anorthite is a calcium feldspar.
