geothermal brine

geothermal brine Hot, concentrated, saline solution that has circulated through crustal rocks in an area of anomalously high heat flow and become enriched in substances leached from those rocks (e.g. chlorides of Na, K, and Ca); it often contains dissolved metals, in which case it forms an important intermediary in the deposition of ore deposits. One of the best documented examples is the brine from bore-holes in the Salton Sea geothermal field in southern California, discovered in the early 1960s, with temperatures between 300 and 325°C, density 1021 kg/m3, and containing appreciable concentrations of Cu, Pb, Zn, and Ag. Hot brine solutions may also form through sea water—rock reactions in hydrothermal systems at oceanic ridges, e.g. in the median valley of the Red Sea.

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.
