Granite rocks typically exhibit a phaneritic texture, showcasing light-colored igneous material predominantly composed of feldspars and quartz, with minor inclusions of mica and amphibole minerals. Granite is considered a plutonic rock where quartz constitutes between 10 and 50 percent of the felsic components, while alkali feldspar accounts for 65 to 90 percent of the total feldspar content.
