China's main sandstone origin

China as the world's three largest sandstone origin, has one of the most abundant mineral resources, and because the sandstone China region is vast, complex geological environment, China sandstone varieties are many, but sichuan province has 100 DuoGe ore. Although China's sandstone varieties are many, but the Lord is concentrated in sichuan, yunnan and shandong, this is one of the three Chinese sandstone, and at the same time in hebei, henan, shanxi, shaanxi have, but fame is not high, small influence.
Now is the key introduction to China's three big sandstone origin:
A, sichuan Sandstone Slab
Sichuan sandstone belongs to, the fine particles of mud sandstone, the soft texture, very suitable for building decoration materials, especially as used for carving using stone. And because the sichuan geographical geological condition is more complex, so the sandstone varieties of sichuan is very much. The color of sichuan sandstone can be said to be the whole of China's most abundant, there are red, green, gray, white, black, purple, yellow, green, etc, very much. But because of its material relatively soft, and traffic inconvenience, mining way also is relatively backward, so the supply of basic sichuan sandstone article is unable to provide the board, more than 1 m of the big board. But if the small number of cases, the mining area may adopt disk saw cut way, turn a few supply, but due to the damage rate is higher, the price is expensive. But there is a kind of sandstone in sichuan so-called hardness comparable granite, some of the sandstone material to pledge harder can do fire processing.
Second, yunnan Sandstone Tile
Yunnan sandstone with sichuan sandstone mud sandstone, the same as belong to the grain is exquisite, the soft texture. But because of the geological formation geographical environment different, yunnan, sichuan sandstone in sandstone relative texture will be more beautiful, have their own characteristics of style, the color of yunnan sandstone is very rich, common have yellow wood grain sandstone, the landscape lines sandstone, the red, yellow, white sandstone sandstone and blue sandstone.
Because of the sandstone industry in yunnan started more early, mining processing technology is opposite taller, can supply more than 1 m of the big board, but because the soft texture of mud sandstone, the application will be limited in general specification board to give priority to.
Three, shandong sandstone
Shandong sandstone of sea sandstone, the structure grain is thick, hardness is bigger, but is fragile. Shandong sandstone basic can cut into 1.2 m above the big board, some even being used as a panel, many can make 1 cm sheet. Because of its hardness is enough, so to almost all of the surface processing. Shandong sandstone color relatively less, basically have red, yellow, green, purple, brown, white. But shandong sandstone basic is take the grain, even the so-called white sandstone and violet arenaceous rock are not all pure color, white sandstone with dark grain, violet arenaceous bald rock.
Hebei henan sandstone and shandong sandstone close to the sea, also of sandstone, coarse particles, hardness, but color less, with wood grain sandstone primarily.
