Rocks made of Limestone (calcite) is an exception, having elaborate subclassifications and even two competing classification methods: Folk Classification and Dunham Classification [ 11 ; 21 ].Sedimentary rocks typically occur in layers or strata. Groups of strata are often called formations, which typically have distinct characteristics, and are mapable over a geographic area. The boundary between two formations (or any distinct layers) is called a contact. Sedimentary rocks cover 75% of continents. Sedimentary rocks preserve a ...A classification groups together objects by some theoretical principle; see, for example, discussion of basic classification. A key is just a method of identification, and subdivides objects only for that purpose. Do not expect the classification and key to match up well. In this key, clastic, chemical and biochemical rocks are often intermixed.Sedimentary breccia is a type of clastic sedimentary rock which is fabricated from angular to subangular, randomly orientated clasts of different sedimentary rocks. A conglomerate, by using evaluation, is a sedimentary rock composed of rounded fragments or clasts of pre-existing rocks. Both breccia and conglomerate are composed of fragments ...Identifying Sedimentary Rocks. Classification of sedimentary rocks is largely based on differentiating the processes that lead to their formation. The biggest division in sedimentary rock types is based on the primary type of weathering that leads to the material building the sedimentary rock.The porous sedimentary rock has a considerable amount of practical uses around the home.
