A pile of minerals. This image shows some of the most common minerals you'll find in rocks. This pile contains plagioclase feldspar, potassium feldspar, quartz, muscovite mica, biotite mica, amphibole, olivine, and calcite.otassium feldspar is another member of the feldspar mineral family. Like plagioclase feldspar, potassium feldspars are silicate minerals that contain a considerable amount of-you guessed it-potassium.
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.
