glaucophane-schist facies

glaucophane-schist facies A set of metamorphic mineral assemblages produced by metamorphism of a wide range of starting rock types under the same high-pressure/low-temperature metamorphic conditions and typically characterized by the development of the mineral assemblage glaucophane—lawsonite—quartz in rocks of basic igneous composition. Other rocks of contrasting composition, for instance shales or limestones, would each develop their own specific mineral assemblage, even though they are all being metamorphosed under the same conditions. The variation of mineral assemblage with starting rock composition reflects a particular range of pressure, temperature and P(H2O) conditions. Experimental studies of mineral P—T stability fields indicate that the facies represents high-pressure/low-temperature conditions which can be met during subduction of oceanic crust under continental crust. Because rocks of basic igneous composition within this facies are characterized by the blue-coloured mineral glaucophane, the facies is sometimes referred to as the ‘blueschist facies’.

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.
