Granite is a granular crystalline rock, the main component of the ore is alkaline feldspar and quartz. Granite hard texture, difficult to be acid or weathering erosion, often used for building materials.
Granite is a volcanic eruption of lava and subject to considerable pressure in the molten state uplift to the crustal surface of the tectonic rocks. It is also considered to be the result of graniteization caused by deep metamorphism and metasomatism. Many non-ferrous metals such as copper, lead, zinc, tungsten, tin, bismuth, molybdenum, precious metals such as gold, silver, rare metals such as niobium, tantalum, beryllium, radioactive elements such as uranium, thorium, etc., are related to granite. Part of the granite will overflow radon, a natural radioactive gas. Radon can cause lung cancer.
