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 is classified into two groups based on how they form. They are clastic and chemical. Clastic sedimentary rock is formed as bits of weathered rock become cemented together.Because all kinds of rock are subject to weathering many different minerals can make up this group of rocks. Clays and quartz are the most common.Classification of clastic sedimentary rocks is done according to the size of the sediments that make up the rock. The following table contains the major groups of clastic sedimentary rocks with their characteristics:edimentary rock is classified into two groups based on how they form.
