Extended data

Granite is acidic (SiO 2 >；; 66%) intrusive rocks in magmatic rocks are the most common in this kind of rocks, mostly light red, light gray and grayish white. Medium-coarse and fine-grained structure, block structure. There are also some variegated structures, spherical structures and gneiss-like structures.

The main minerals are syenite, potash feldspar and acid plagioclase, and the secondary minerals are biotite, amphibole and sometimes a small amount of pyroxene. There are many kinds of accessory minerals, including magnetite, sphene, zircon, apatite, tourmaline and fluorite. It is the most abundant in all kinds of magmatic rocks, with a content of 20-50%, and a few can reach 50-60%.
