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.
Biotite is the most abundant mica in the quartz-rich regions and exhibits a weak planar foliation. Quartz and feldspar crystals are up to 0.5 mm in size. The mica-rich lithology is dominated by muscovite, with minor (<20 vol%) biotite, quartz and plagioclase. Mica grains are upto 2 mm in length and exhibit a well developed planar foliation. Garnet porphyroblasts are present in both lithologies.
