hyaloclastite

hyaloclastite An aggregate of fine, glassy debris formed by the sudden contact of hot, coherent magma and either cold water or water-saturated sediment. Rapid heat loss from the magma to the cold water sets up tensile thermal stress in the magma carapace as it cools, chills, and contracts, causing the glassy, chilled zone to fragment and form a quench-fragmented debris. Thick hyaloclastite deposits form over basalt flows when they erupt beneath the sea or enter the sea. If the deposit remains in contact with water after its formation, the glassy debris can easily be hydrated to form palagonite.

Citation styles

Encyclopedia.com 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, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com 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:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com 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.
