Industrially, sandstone is used as a raw material for manufacturing and in construction. Naturally, sandstone functions as an aquifer and as a reservoir for oil and gas. Sandstone is composed of rock or organic material and sand-sized miner...Grain size is the average diameter of sediment fragments in sediment or rock. Grain sizes are delineated using a logbase-2 scale [ 9 ; 10 ]. For example, the grain sizes in the pebble class are 2.52, 1.26, 0.63, 0.32, 0.16, and 0.08 inches, which correlate respectively to very coarse, coarse, medium, fine, and very fine granules.Texture (grain size) Coarse (over 2 mm) Medium (1/16 to 2 mm) Fine (1/16 to 1/256 mm) Very Fine (less than 1/256) Composition Calcite Quartz Gypsum Halite Altered plant fragments Clastic Sedimentary Rocks Sediment Name Gravel (rounded fragments) Gravel (angular fragments) Sand Mud Mud Chemical Sedimentary Rocks Texture (grain size) Modified date: 23/04/2023. Chert. Chert is a fine-grained sedimentary rock composed of quartz (SiO2) that is microcrystalline or cryptocrystalline quartz. It is usually organic rock but also occur inorganically as a chemical precipitate or a diagenetic replacement. It occurs as nodules, concretionary masses, and as layered deposits.
