Author Guidelines

Guidance for Contributors to Episodes


Episodes is distributed to a wide range of scientists in over 150 countries. It aims to keep readers informed of new and current developments in earth science and is a vital communications link in the global geological community.

General Policy

Articles may take the form of current reviews, new research results of international significance, or discussions of the infrastructure of science; the latter may cover techniques, research programs, organizations, information, or national and international policies in earth science. Articles should be written for a broad international readership of professional geoscientists rather than small groups of specialists. The language used should be intelligible to those whose mother tongue may not be English.


Articles are normally from 4000 to 6000 words long, but shorter articles are also acceptable. Printed, they generally total five to seven pages, including illustrations. Articles must be written in English. Authors whose native language is not English are strongly urged to have their manuscript reviewed before submission by a person whose native language is English. Text should be submitted in hard copy and on diskette preferably in plain text format. E-mail transfer of text is encouraged.

An abstract of no more than 200 words must be included. Acknowledgements may be included in a brief statement at the end of the article. Metric units should be used and all nonstandard symbols, abbreviations and acronyms must be defined. References cited should follow the style shown below. These examples include a serial publication, a map, an abstract, a report of a meeting, and a text book.Handin, J.W., and Griggs, David, 1951, Predicted fabric changes, pt.2 of Deformation of Yule Marble: Geological Society of America Bulletin, v. 62, no. 8, pp. 863-866.Harrison, J.E., Griggs, A.B., and Wall, J.D., 1986, Geologic and structure maps of the Wallace 1-degree x 2-degree quadrangle, Montana and Idaho: U.S. Geological Survey Miscellaneous Investigations Series Map I-1509-A, scale 1:25.000.Street, R.L., and Herriman, R.B., 1974, Earth­quake mechanics in southeast Missouri and adjacent areas (abs): Geological Society of America Abstracts with Programs, v. 6, no. 3, pp. 312-313.Thayer, T.P., 1960, Some critical differences between Alpine-type and stratiform peridotite-gabbro complexes: 21st Interna­tional Geological Congress, Copenhagen, 1960, Report, pt. 13, pp.247-259.Thompson, J.B., Jr., Norton, S.A., 1968, Paleozoic regional metamorphism in New England and adjacent areas, in Zen, E-an, White, W.S., Hadley, J.B., and Thompson, J.B., eds, Studies of Appalachian Geology, northern and maritime: New York, Interscience Publishers, pp. 319-337.


Good illustrations are essential and may include line drawings, photographs, and/or tables incorporating graphics. Line drawings should be simple and clear. Avoid the use of light lines and screen shading. Instead, use black-and-white, hatched, cross-hatched designs or symbolic patterns for emphasis; since repeated scanning can cause moirs in shading areas. Color figures should be submitted digitally, if possible. Authors who prefer to submit their line drawings electronically may supply vector image files produced with Adobe Illustrator, CorelDraw or Freehand.Photographs should be sharp, of good contrast and preferably in the form of prints rather than transparencies or negatives. Articles are normally published in black-and-white but it may sometimes be possible to include color illustrations at the author's expenses. Other illustrations should be presented as positives, either on transparent film or on white paper (not card). Do not place captions on any illustrations; number illustrations carefully with soft pencil on the back and list the captions at the end of the article. Originals should not be greater than A4 size and lettering should be capable of being reduced to up to 60 percent. Please note that photographic prints may be damaged or made unusable by the use of paper clips, by mounting them on card, or by writing on the back. Illustrations previously published and unchanged from the original must be accompanied by permission from the original publisher to republish. This is the responsibility of the author, not Episodes.


Tables with text only and without graphics may be placed by the author within the text of the article for typesetting by Episodes staff. Alternatively, text or numerical tables compiled in a standard spreadsheet package may be submitted along with details of the software used.

Author's Biographical Note

A passport-size photograph and a brief (maximum of 100 words) biographical sketch of each author must accompany each article. If the number of authors of any article exceeds 3, a group photo of all authors or passport-size photograph(s) of at most 3 authors are requested. Address of each author should be typed under the title of the article.

Submission of Articles

All articles will be subject to review for interest and scientific soundness. Text for an article and copies of all illustrations may be submitted to the Editor by any convenient means, and must include the author's name and all relevant contact addresses. Original illustrations should be supplied after any changes requested by the Editor have been made and after acceptance of the article. The Editor cannot guarantee that an article will be published on a particular date or in a particular issue of Episodes. The Editor reserves the right to reject all or any part of the article submitted. The IUGS assumes no responsibility for statements made by contributors.

Printing and Publication

All accepted articles are edited to conform to the style of Episodes and to improve clarity. When major changes are deemed to be necessary, the Editor will consult with the author by the most convenient means, and the manuscript may be returned to the author for approval or further clarification. Page proofs will be supplied to authors. After publication, Episodes will provide the authors a copy of the journal in which their article is published.


Authors may purchase reprints of articles provided that orders are placed and payments made prior to publication. The Editor will supply price quotations on request.
