Size: 10 cm x 9 cm x 5 cm
Type: Igneous intrusive (plutonic) rock
Description: Granites are very common plutonic rocks, phaneritic rocks, light-colored, consisting primarily of Quartz and Alkali-feldspar (may contain small content of plagioclase). May contain mafic minerals (ferromagnesian minerals) and/or accessory minerals.
Essential minerals: quartz, potassic feldspar (orthoclase, microcline), ± plagioclase, biotite.
