how granite
Qingdao qixia litchi below small make up tell you how granite formed
Granite is a volcanic eruption of lava and swell under considerable pressure in molten state to the earths crust, the structure of the surface rocks. Also some people think that is caused by deep metamorphism and metasomatism of the consequence of granitization. Many non-ferrous metals such as copper, lead, zinc, tungsten, tin, bismuth, molybdenum, such as precious metals such as gold, silver, precious metals such as niobium, tantalum, beryllium, radioactive elements such as uranium, thorium, etc., are related to granite. In the earth surface layer formation, move slowly cooled down. Belongs to one kind of igneous rock, volcanic rock is made with Silicate (Silicate) molten magma or lava cooling solidification crystallization of a substance. When molten lava condensation consolidation, mineral that is formed in the igneous rock, such as olivine and pyroxene. The density of the largest iron and magnesium silicate minerals in the magma formed at the highest temperature; Mineral density is small, such as feldspar and quartz, is formed in the late stage of cooling. Formed in the minerals in the lava, usually can grow without restraint, and a good-quality crystal shape.
Due to the high hardness granite, durable, is the production of wall brick floor and on the ideal material. Because granite than ceramics rare or any other synthetic material, so the shop buy granite floor can greatly increase the value of real estate. Granite varieties, color variety, can provide customers with wide range of options. Granite countertops are easy to maintain, strong ability to resist pollution. In general, spread granite wall brick can provides users with an extremely durable and easy to maintain surface. In addition, different from artificial synthetic material, natural granite countertops have distinct temperature tolerance, so the first choice for all kinds of sheet metal processing. Natural stone yamei cluster technology limited stone, marble, marble fireplace.
A deep into acidic igneous rocks, belong to magmatic rocks. Commonly known as granite. Silicon dioxide content in more than 70%. No bedding block, granite Mosaic structure, often by the spherical weathering. Shallow color, gray, red meat is the more common. (7) hardness is mainly composed of quartz, feldspar (6) hardness and small amounts of biotite (such as hardness is 2-4) dark mineral composition. Quartz content is 20% ~ 20%, alkali feldspar than plagioclase, accounts for
Granite uniform structure, quality of a material is solid, color beautiful, is a high-quality building stone.
