What is the difference between marble and granite
Because natural stone surface pores, so in terms of pollution is relatively weak. Generally in the processing plant will be on its surface processing. In the interior decoration, the TV table, window sill, indoor floor, such as the use of marble. The threshold, kitchen cabinets, outdoor floor is suitable for the use of granite. Which is the best use of kitchen countertops granite.Now on the market sales of natural stone, part of the color is artificial, these stones generally use half a year or so will show their true faces. The most obvious is now on the market of big flower green, a lot of is dyed, not really big flower green.
Granite is igneous rock, also called acid crystallization plutonic rocks, is one of the most widely distributed rock in igneous rock composed of feldspar, quartz and mica, the composition of silica, about 65% ~ 75%, hard rock compacting. Lava condensation crystallization of igneous rocks is underground magma or volcano eruption called and rock. The content of silica, the properties and content of feldspar determine the properties of stone. When the content of silica is greater than 65%, it belongs to the acid rock, the rock in the feldspar, Xie Changshi, quartz and other basic minerals to form crystals, granular structure, called granite.Marble is a metamorphic rock formed by high temperature and high pressure in the earth's crust. The action of the internal force of the earth's crust promotes the change of the original rock. Qualitative change is the change of the structure, structure and mineral composition of the original rock. A new type of rock formed by qualitative change is called metamorphic rock. Marble is mainly composed of calcite, limestone, serpentine and dolomite. The main components of calcium carbonate, accounting for more than 50%. Other magnesium carbonate, calcium oxide, manganese oxide and silicon dioxide. Because marble is generally contain impurities, and calcium carbonate by carbon dioxide, carbide, the role of water vapor in the atmosphere, but also easy to weathering and erosion, and make the surface soon lose luster, relatively soft marble of a general nature, which is relative to the granite character. Of course, you don't need to bother about this, because the geological age is calculated by 100 million in the US, the rest of life, this qualitative change is a change of the co..
Natural stone in daily use is mainly divided into two kinds: marble and granite.In general, there is a texture, known as marble, to the point of the main spots known as granite. This is broadly speaking. In a narrow sense, marble refers to the stone produced in Yunnan, Dali. In fact, there are not a few stones around the country is out of Dali.
