Composition: potassium aluminium silicate.Formula: KAlSi3O8.rÂ·thoÂ·clase. A type of feldspar consisting of potassium aluminum silicate.

The eight include the two feldspars plagioclase and orthoclase (potassium feldspar), quartz, the micas muscovite and biotite, the amphibole mineral hornblende, the pyroxene mineral augite, and the green mineral olivine.he feldspars are the most common mineral family in the crust of the Earth (about half of all minerals). This is a sample of potassium feldspar (orthoclase). Potassium feldspar (orthoclase) is often pinkish in color and displays the property of cleavage, the tendency to break along flat planes. It is harder than glass.
