    en.wikipedia.org/wiki/Red_beds

    Red beds (or redbeds) are sedimentary rocks, typically consisting of sandstone, siltstone, and shale, that are predominantly red in color due to the presence of ferric oxides. Frequently, these red-colored sedimentary strata locally contain thin beds of conglomerate , marl , limestone , or some combination of these sedimentary rocks.

    en.wikipedia.org/wiki/Red_Beds_of_Texas_and_Oklahoma

    The most prolific fossil site in the red beds is the Geraldine Bonebed within the Nocona Formation of the Wichita Group. [6] During the Permian, the bonebed was the site of a freshwater pond. After a catastrophic event this became the burial site for a variety of terrestrial and marine animals. [ 15 ]

  4. Bedform - Wikipedia

    en.wikipedia.org/wiki/Bedform

    These phase diagrams [1]: 1 [9] are used for two main purposes: i) for prediction of bed states in a known flow and sediment transport condition, and, ii) as a tool for the reconstruction of paleoenvironments from a known bed state or sedimentary structure. Despite the great utility of such diagrams, they are very difficult to construct, making ...

  5. Sedimentary structures - Wikipedia

    en.wikipedia.org/wiki/Sedimentary_structures

    These structures are within sedimentary bedding and can help with the interpretation of depositional environment and paleocurrent directions. They are formed when the sediment is deposited. Cross-bedding Cross-bedding is the layering of beds deposited by wind or water inclined at an angle as much as 35° from the horizontal. [1]

  6. Bed (geology) - Wikipedia

    en.wikipedia.org/wiki/Bed_(geology)

    In geology, a bed is a layer of sediment, sedimentary rock, or volcanic rock "bounded above and below by more or less well-defined bedding surfaces". [1] A bedding surface is three-dimensional surface , planar or curved, that visibly separates each successive bed (of the same or different lithology ) from the preceding or following bed.

    Outcrops of this brightly colored red, brown, and pink banded formation can be seen in the Kolob Canyons section of the park and in buttes on either side of State Route 9 between Rockville, Utah, to the south and Virgin, Utah, to the southwest of the park borders. Progressively higher beds are exposed until the top of the formation is reached ...

    Prior to the rifting which formed the Gulf of Mexico basin, extensional deformation in the Late-Triassic caused by the breakup up of Pangaea, and more specifically the rifting of the Atlantic Ocean, created basement graben formations which filled with terrestrial red bed sediments, and volcanic sediments from the eruption of the Central ...
