heterolithic bedding

heterolithic bedding A closely interbedded deposit of sand and mud, generated in environments where current flow varies considerably. The three main types of heterolithic bedding are called flaser, wavy, and lenticular. Flaser bedding is characterized by cross-laminated sands with thin mud drapes over foresets. Wavy bedding consists of rippled sands with continuous mud drapes over the ripples. Lenticular bedding consists of isolated lenses and ripples of sand set in a mud matrix. Heterolithic sediments can be deposited in storm-wave influenced shallow marine environments, river floodplains, tidal flats, or deltafront settings where fluctuating currents or sediment supply permit the deposition of both sand and mud.

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
