Sandstone is made of what material?

Sandstone is made of what material?

Answer:

The sandstone is a sedimentary rock is composed of stone through water erosion sedimentation in the river, after thousands of years of accumulation of strongand. Due to the earth's crust movement, and the formation of today's mines. The main origin of Sichuan sandstone and Yunnan, Neijiang.Sichuan belongs to the sandstone siltstone, fine particles, soft texture, very suitable for building decoration materials, especially used for carving stone. Because of Sichuan's geography and geological condition is very complex, so Sichuan sandstone varieties very much. Sichuan sandstone color can be said that the Chinese most fruitful, red, green, gray, white, black, purple, yellow, blue and so on, very much. But because the material is relatively soft, and the inconvenience of traffic, mining method is relatively backward, so the basic supply of Sichuan sandstone is a plate, can not provide more than 1m plate. But if a small number of cases, a small amount of mine may adopt circular saw turning way of supply, but because of the breakage rate is high, the price is more expensive. But Sichuan has a hardness comparable sandstone known as granite, some sandstone material is hard to do with fire Work.
Quartz and feldspar clastic sedimentary clastic rock components accounted for more than 50%. The sandstone is the source rocks by weathering, denudation and accumulation in the basin. The formation of moving rock is composed of two parts of clastic and interstitial material. Besides detrital quartz and feldspar and Bai Yunmu, heavy mineral and rock debris. Fillings include cement and miscellaneous debris based on two components. The common cements are siliceous and carbonate cementation; matrix composition mainly refers to the deposition and debris and finer particles of clay or silty. The composition and structure of interstitial material reflect the geological environment and the physical and chemical conditions of formation of sandstone. Sandstone according to the sedimentary environment can be divided into: quartz sandstone, feldspar sandstone and lithic sandstone. Three types of sand and sandstone constitute the main reservoir of oil and natural gas and groundwater reservoir. Sandstone and sand can be used as abrasive, glass raw materials and building materials. A certain attitude Sand and sandstone is rich in gold, diamond, zircon, ILMENITE PLACER and Jin Hongshi.The sandstone is a sedimentary rock is composed of stone through water erosion sedimentation in the river, after thousands of years of accumulation of strongand. Due to the earth's crust movement, and the formation of today's mines. The main origin of Sichuan sandstone and Yunnan, Neijiang.
The quartz particles (sand) formation, stable structure, usually pale brown or red, mainly containing silicon, calcium, clay and iron oxide. The sandstone is a sedimentary rock composed mainly of sand and cement, the sand particle content is greater than 50%. in most of the sandstone is composed of quartz or feldspar.
