Sandstone is formed by weathering, denudation and transportation of source rocks in the basin.
Rock consists of debris and interstitial materials.
In addition to feldspar, there are muscovite, heavy minerals and cuttings.
The filler consists of two components: cement and macadam matrix.
Common cements are siliceous cements and carbonate cements.
Heterobase composition mainly refers to clay or silty material with fine particles deposited at the same time as debris.
The composition and structure of interstitial materials reflect the geological tectonic environment and physical and chemical conditions of sandstone formation.
Sandstone can be divided into timely sandstone, feldspathic sandstone and lithic sandstone according to its sedimentary environment.
Sandstone and sandstone constitute the main reservoirs of oil, natural gas and groundwater.
Sand and sandstone can be used as abrasives, glass raw materials and building materials. Sandstone and sandstone have certain occurrence and are rich in placer gold, zircon, diamond, ilmenite and rutile.
Sandstone is the most widely used stone for human beings.
Its noble and elegant temperament and the characteristics of natural environment have created many wonderful flowers in the history of architecture.
The Louvre, the British Palace, the US Capitol, Harvard University and Notre Dame de Paris, which were decorated with sandstone hundreds of years ago, still have charm.
