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.
sedimentary rock, composed of rounded, mostly water born, gravel-size pebbles in a finer sediment matrix. Conglomerate is the consolidated equivalent of gravel. The size of the fragments refers to a mean particle diameter above 2 mm (more than 50% of the particles have to be larger than 2 mm), below this grain size: sandstone. conglomerates are composed of rounded fragments (contrary to breccias).
