How to distinguish the types of granite

Granite is an igneous rock, formed by underground magma eruption and intrusive cooling crystallization, as well as granitic metamorphic rocks. It has visible crystal structure and texture. It is composed of feldspar (usually potash feldspar and austenitic) and quartz, mixed with a small amount of mica (biotite or muscovite) and trace minerals, such as zircon, apatite, magnetite, ilmenite And sphene and so on.

If you want to rebuild your house using granite as one of the building materials, you need to decide which granite to use. The decision to find the color or pattern you like is much more complicated.
