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.
Detrital Rocks-these rocks have a clastic texture, that is they are composed of fragments compressed and cemented together. In detrital rocks, the clasts are fragments of detritus, the product of weathering of pre-existing rocks.Non-detrital rocks-these rocks can have clastic or crystalline textures.They are made from materials which did not directly result from the weathering of other rocks.alcite: calcite forms and is stable at the Earth's surface. Some calcite is formed from precipitation, but much of the calcite in sedimentary rocks is formed by biological activity. Many marine organisms secrete skeletal material (shells) of calcite.
