Types of Sedimentary Rock - ThoughtCo
WebCoarse-grained sediment and poorly sorted rocks are usually found nearer to the source of sediment, while fine sediments are carried farther away. In a ... and sorting. Some … WebHowever, the sediment is usually poorly sorted because the flow is a slurry of water and sediment so hydraulic sorting is reduced. (Facies = Bouma a) Sediment concentration decreases with deposition, so one gets more hydraulic sorting. The flow is very fast so the sediment has upper planar lamination. (Facies = Bouma b) WebSandstone is a clastic sedimentary rock made from medium sized grains (1/4 to 2 mm). These grains are fragments of other rocks or minerals, bound together by cement. Depending on the variety of sandstone, the grains may range from poorly sorted to well sorted. Likewise, the grains may be rounded or angular. greece drawing easy
