Such sedimentary rocks are called clastic (meaning "broken pieces") rocks. Other sedimentary rocks may be formed by chemical precipitation from water (chemical) or consist of fossil remains (organic). Clastic sedimentary rocks are classified by their grain size or texture (examples include gravel, sand, silt, and clay) and their mineral composition....
