Specific to layered sedimentary rocks, geologists long ago determined that studying such layers -- what is called the âsuperpositionâ of the rocks -- is the key to tracking the Earthâs evolution, including the ebb and flow of oceans, lakes and rivers, and the shifting of sands and other forms of sediment.
Sedimentary Rocks. Sedimentary rocks are rocks composed of sediment. Sediment is deposited in a number of environments of deposition, by both moving air and moving water. Sedimentary rock identification is primarily based on composition. Texture will still be used but in a different sense than for igneous rocks.lastic sedimentary rocks contain clasts. These are fragments or pieces of rock or minerals. The composition of clastic sedimentary rocks is divided into three types-clay/silt, sand and gravel. Clay and silt are less than 1/16 mm. These are not visible to the unaided eye.
