Granite belongs to intrusive rocks in acidic (SiO2>66%) magmatic rocks, which is the most common type of rock in this category, mostly in light flesh red, light gray, gray white, etc. Medium coarse grain, fine grain structure, blocky structure. There are also some structures such as speckled structures, spherical structures, and gneiss like structures. The main minerals are quartz, potassium feldspar, and acid plagioclase, while the secondary minerals are biotite, amphibole, and sometimes a small amount of pyroxene. There are many types of accessory minerals, including magnetite, garnet, zircon, apatite, tourmaline, fluorite, etc. Quartz content is the highest among various magmatic rocks, ranging from 20% to 50%.
