  2. Aeolian processes - Wikipedia

    en.wikipedia.org/wiki/Aeolian_processes

    Aeolian processes are those processes of erosion, transport, and deposition of sediments that are caused by wind at or near the surface of the earth. [1] Sediment deposits produced by the action of wind and the sedimentary structures characteristic of these deposits are also described as aeolian. [5]

  3. Loess - Wikipedia

    en.wikipedia.org/wiki/Loess_soil

    The largest deposit of loess in the United States which is the Loess Hills along the border of Iowa and Nebraska, has survived intensive farming and poor farming practices. For almost 150 years, this loess deposit was farmed with mouldboard ploughs and tilled in the fall, both intensely erosive practices. At times it suffered erosion rates of ...

  4. Aeolian landform - Wikipedia

    en.wikipedia.org/wiki/Aeolian_landform

    Lag deposit: Angular rocks and sand grains that have been left behind during the gradual removal of finer particles by aeolian processes. Lag deposits can also form due to removal of finer particles by water. Yardangs: A protruding rock that results from a streamlined carving from consolidated material by wind abrasion by dust and sand, and ...

  5. Depositional environment - Wikipedia

    en.wikipedia.org/wiki/Depositional_environment

    A diagram of various depositional environments. In geology, depositional environment or sedimentary environment describes the combination of physical, chemical, and biological processes associated with the deposition of a particular type of sediment and, therefore, the rock types that will be formed after lithification, if the sediment is preserved in the rock record.

  6. Geology of Illinois - Wikipedia

    en.wikipedia.org/wiki/Geology_of_Illinois

    Paleogeographic reconstruction showing the Illinois Basin area during the Middle Devonian period. [9] Almost all Silurian rocks in Illinois are deep-water limestone and dolomite deposits; reef habitats were common, and fossils of reef organisms are locally highly abundant, including corals, brachiopods, crinoids, stromatoporoids, and bryozoans. [6]

  7. Eolianite - Wikipedia

    en.wikipedia.org/wiki/Eolianite

    Eolianite or aeolianite is any rock formed by the lithification of sediment deposited by aeolian processes; that is, the wind. In common use, however, the term refers specifically to the most common form of eolianite: coastal limestone consisting of carbonate sediment of shallow marine biogenic origin, formed into coastal dunes by the wind, and ...

  8. Mahomet Aquifer - Wikipedia

    en.wikipedia.org/wiki/Mahomet_Aquifer

    The Mahomet Aquifer consists of sand and gravel deposited by glacial meltwater flowing westward along the Mahomet Bedrock Valley during the Pre-Illinoian glacial episode. [further explanation needed] This bedrock valley forms the western part of the Teays-Mahomet Bedrock Valley System that extends into Illinois from Indiana (Larson et al., 2003).
