Sedimentary rocks are produced by the weathering of preexisting rocks and the subsequent transportation and deposition of the weathering products.

Jun 23, 2017 · Sedimentary rocks formed by the crystallization of chemical precipitates are called chemical sedimentary rocks. As discussed in the “Earth's Minerals” chapter, dissolved ions in fluids precipitate out of the fluid and settle out, just like the halite in Figure below . Breccia – Rock composed of broken fragments cemented by a matrix. Calcarenite – Type of limestone that is composed predominantly of sand-size grains. Chalk – Soft, white, porous sedimentary rock made of calcium carbonate. Chert – Hard, fine-grained sedimentary rock composed of cryptocrystalline silica.The sediment can be organic or inorganic. An interesting fact about sandstone is that it is an integral part of all sedimentary rocks. Some sedimentary rocks may have up to 20-25% sandstone.
