Statistics show that granite is one of the oldest rocks on the earth with a history of more than 300 million years. Granite is the most widespread igneous rock and is the main material for the Tianzhushan Global Geopark, Menkaure's Pyramid, etc. Granite is formed by the cooling of magma, so it is called intrusive rock; the forming depth is usually 5 to 30 kilometers below the earth's surface, so it is also called deep-seated rock.

What color is granite?

The color of granite depends on its components, usually presenting red, pink, gray, white, black, and other dark colors. If granite contains much potash feldspar, it will be pink; if it contains much quartz, it may appear white. Quartz-typically milky white Feldspar- typically off-white Potash feldspar- typically pink Biotite- typically black or dark brown Muscovite- typically gold or yellow Amphibole - typically black or dark green

How is granite formed?

Granite is formed by the cooling of magma. There is a deep layer of molten rock in the depths of the earth and beyond the mantle layer. Molten rock is formed when the natural radioactive elements in the ground decompose and decay. The reaction of the decaying matter releases a lot of heat, melting the surrounding rocks. As geological matters occur (such as the plate movements), molten rock is pushed to the surface of the earth. As the rock approaches the ground, it will cool, forming an internal igneous rock. Granite is one of these igneous rocks, which can be a mixture of mainly quartz and feldspar.
