GSA Citation Style Tips

Journal Articles

The most common items cited in geoscience research are journal articles. GSA citation style does not distinguish between print or online journal articles, but a DOI should be included if available. See the style guides above for information on citing books, abstracts and other information formats.

Basic format:

Author, A.A., Author, B.B., and Author, C.C., Year, Title of article: Title of Journal, v. #, p. ##-##, doi: 10.####/####

Examples:
