1. If a substance is dissolved in two immiscible liquids standing in contact with each other, the substance will partition or distribute itself between them in a constant ratio, called the partition coefficient. The value of this constant is dependent on the temperature, and on the identities of the solute and the solvents. (The number of solute molecules in solvent A divided by the number of solute molecules in solvent B is a constant.)
2. The ratio of the concentration (by weight) of an element (e.g. Ti) in a crystallizing mineral to its concentration in the magma. For example, KTi = [Ti]min./[Ti]magma, where kTi is the partition coefficient for Ti, and [Ti]min. and [Ti]magma are the concentrations of Ti in the mineral and magma respectively. The value of k is dependent on temperature, pressure and the composition of crystallizing mineral and magma.

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:
Modern Language Association
The Chicago Manual of Style
American Psychological Association
- 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.
