  • The Rock GRANITE (Igneous Intrusive Rock)

    The minerals that are found in granite are primarily quartz, plagioclase feldspars, potassium or Kfeldspars, hornblende and micas. Quartz is usually the last mineral to crystallize and fills in the extra space between the other minerals. Quartz's hardness, lack of chemical reactivity and near lack of cleavage give granite a significant amount of its desirable durable properties.
