Sediment builds up, and with the passage of time, the layers are compacted and cemented together to form sedimentary...Sedimentary rocks are layered. Some form when particles of rocks and minerals settle out of water or air. Others form when minerals precipitate directly out of water. ... Clay and silt are deposited in slow-moving rivers, at the far ends of deltas, and in other quiet environments where slow-moving water cannot keep the particles suspended.Sedimentary rocks are rocks made by sediment that has accumulated over millions of years. This sediment can accumulate on the surface of the Earth or under water.

The third sediment type is pelagic clay. Very fine-grained clay particles, typically brown or red, descend through the water column very slowly. Pelagic clay deposition occurs in areas of remote open ocean, where there is little plankton accumulation. Figure \(\PageIndex{4}\): Turbidites inter-deposited within submarine fans.Illite abundance may also relate to authigenic illite within exposed sandstones, or result from weathering of argillaceous sedimentary rocks (Pearson, 1990). Illite and related mixed layer minerals (e.g., illite-smectite) can be found particularly in arid and semi-arid regions, where poorly drained areas ensure minimum leaching.Nov 23, 2020 · Sedimentary rocks are formed from deposits of pre-existing rocks or pieces of once-living organism that accumulate on the Earth's surface. If sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock. These rocks often have distinctive layering or bedding and create many of the picturesque views of the desert southwest. Dear Colleagues, Sedimentary rocks cover about 80% of the Earth’s surface, and clays represent well over 40% of sedimentary rocks. The wide diffusion of these sediments and their characteristics (large specific surface, cation exchange capacity, water retention capacity, thixotropy, etc.) make clays extremely important for their large …
