Conglomerates form in high-energy environments such as fast-flowing rivers, where the particles can become rounded. The sedimentary rock is formed by the settlement and subsequent cementation of mineral or organic particles on the floor of oceans or other collections of water. The broken pieces are similar to conglomerate because of their large pea-sizes. Sedimentation is the collective name for processes that cause these particles to settle in place. Sedimentary rocks are of three types – clastic sedimentary rocks (detrital), organic sedimentary rocks (biochemical), and chemically precipitated sedimentary rocks. Some materials may settle within water bodies and others on land. Sandstone. All types of rocks are relentlessly exposed to erosion and weathering. Clastic sedimentary rocks are composed of rock fragments (clasts) that have been cemented together. Clastic Sedimentary Rocks. For example, if the mode of transport is by sliding down a slope, the deposits that result are generally chaotic in nature, and show a wide variety of particle sizes. Sketch and provide examples of 3 different clastic sedimentary rocks. Clastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Chemical sedimentary rocks are formed when the water components evaporate, leaving dissolved minerals behind. Key Terms Cementation: The process by which clastic sediments become lithified or consolidated into hard, compact rocks, usually through deposition or precipitation of minerals in the spaces among the individual grains of the sediment. Over long periods of time, the debris ultimately settles through sedimentation. Clastic sedimentary rocks are formed from pieces of other rocks that are glued together. Clastic sedimentary rocks form by weathering processes which break down rocks into pebble, sand, or clay particles by exposure to sun, snow, wind, ice, and water.
