Clastic sedimentary rocks form when individual grains (the sediment), made by fragments of rocks, minerals, or shells, are cemented together (the clastic sediemntary rock). These are the only type of rock that is NOT made simply of crystals, but rather fragments of other materials, broken and then reassembled together.
Most sedimentary rocks are derived by processes of weathering, transportation, deposition, and diagenesis. The final texture (grain size, shape, sorting, mineralolgy, etc.) in a sediment or sedimentary rocks is dependent on process that occur during each stage.he fragments may be composed of single minerals, such as clay grains, mica grains, quartz grains, or feldspar grains. However, they may also be fragments of rocks, such as shale clasts, granite pebbles, etc.
