Quartz, feldspar and other debris accounted for more than 50% of the sedimentary clastics. Sandstone is the source of rock by weathering, denudation, handling accumulation in the formation of the basin. The rock is made up of debris and interstitial material. Debris in addition to quartz, feldspar, there are muscovite, heavy minerals, cuttings and so on. The interstitial material includes cementite and clastic debris. Common cements are siliceous and carbonate cement; heterogeneous composition mainly refers to the deposition of debris at the same time more fine particles of clay or silty material. The composition and structure of the interstitial material reflect the geologic structure and physico-chemical conditions of sandstone formation. According to the depositional environment, sandstone can be divided into three categories: quartz sandstone, feldspar sandstone and lithic sandstone.
