Cementation is the gluing of the rock pieces together either by salt compounds or organic matter. Here are the detailed examples of the various sedimentary rocks. Shale consists of clay minerals or clay-sized pieces that have been compacted by the weight of the overlying rock materials. So, sedimentary rocks are produced from previous rocks that are relentlessly weathered or eroded and then deposited where they undergo compaction and cementation through a process known as lithification- changing of sediments into a rock.   Phyllite Those sediments can be formed from the weathering and erosion of preexisting rocks. They are also sometimes referred to as pudding stone. Limestones are chemical sedimentary rocks made up of the mineral calcite. Mature sandstones or quartz sandstones are light-colored and majorly consist of rounded and well-sorted quartz grains. Sedimentary rocks are the most common rocks exposed on Earth’s surface but are only a minor constituent of the entire crust. The formation of sediment and sedimentary rock involves many physical, chemical and biological processes, sometimes operating separately but more commonly in concert. Sedimentation is the collective name for processes that cause mineral and/or organic particles (detritus) to settle in place. Sedimentary rocks form by the compaction and cementing together of sediments, broken pieces of rock-like gravel, sand, silt, or clay (Figure below). (And Which Foods to Avoid), Can Squirrels Eat Raisins?   Gneiss, Conglomerate The weathering and erosion is normally due to the forces of water, thermal expansion, gravity, wind, and salt crystal expansion that breaks down the pre-existing rocks into small pieces and then carried away to some distance low areas.
