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.
Feldspars between albite (contains sodium (Na) and anorthite (contains calcium (Ca)) in composition are termed plagioclase. There is little solid solution between alkali feldspars (contain potassium (K) +/- sodium (Na)) and anorthite (contains Na and or Ca).lthough there is extensive mixing of Na and K or Na and Ca in feldspars when they are formed, as the minerals cool they would rather contain only K or Na or Ca (this is a simplification). This results in unmixing of feldspars when they are cooled, leading to play of color (schiller, labradorescence, or other terms).
