Author Guidelines


Printing and publication

All accepted papers are edited to conform to the style of Episodes and to improve clarity. If major changes are deemed 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 the authors after acceptance.


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

Requirements for contributions

The title of each contribution should be brief, clear and comprehensive. The names, affiliations and e-mail addresses of each author should be typed beneath the title of the paper. Keywords are not required. Authors should be limited to only those who were directly involved in undertaking and reporting the work. Other relevant individuals should be mentioned in acknowledgements. Internally consistent English or American English spelling should be used.

Research and review papers should normally be from 4000 to 6000 words long but shorter articles may be acceptable and the limit may be relaxed for particularly important papers (when printed these normally total 5 to 7 printed pages including illustrations). The content must be well structured with concise explanations of methodology supported by carefully selected figures and tables that are essential to support the text. The discussion and conclusion should advance geological understanding.

Upper case initial letters should be used for formal stratigraphic terms: lower case should be used for informal stratigraphic terms.

Metric units should be used and all non-standard symbols, abbreviations and acronyms must be defined when these are first mentioned.


The names and postal and e-mail addresses should be typed beneath the title of the article. Authors must be limited to those who were directly and substantially involved in the work. This should be confirmed by the authors. Other relevant people should be recognized in the acknowledgements.


An abstract not exceeding 200 words, but covering all aspects of the text, must be included.


Keywords are NOT required.

The text

The text should be formatted for A4 sized paper. Right and left hand margins should be 2.5 to 3 cms wide. Manuscript must be in double-spaced format (line interval: 2) using font size of 12 pt (‘Times New Roman’ font). Continuous line numbers have to be added throughout the manuscript, and page numbers have to be added throughout the manuscript in sequence. Tables and figures should be either placed at the end of the text or uploaded separately but authors should indicate clearly in the text the approximate position where these should appear between (NOT within) paragraphs (e.g., “Figure 1 is about here”)

For good readability of manuscript, authors have to use levels of headings as follows:

Results and Discussion (First Level Heading)

Geochemical Data (Second Level Heading)

Major element chemistry (Third level heading)

High quality Illustrations are essential. These may include line drawings, photographs and/or tables incorporating graphics. Figures must not be inserted into the text: they should either be uploaded as separate files or placed at the end of the contribution. JPG and TIFF formats are preserved. The MINIMUM acceptable resolution is 250 pixels/inch. The shorter side of the figure should be at least 10 cms. If figures consist of several elements these should be compiled into a single JPG or TIFF file that will fit within 1 page or less. The sub-elements should be labelled as (a), (b), (c)......or a, b, c......etc. Figures that do not comply with these rules will be rejected and the contribution involved cannot be sent for review unless these are improved.

Line drawings should be simple and clear. Light lines and screen shading must be avoided because they can produce moirés in shaded areas. Instead, use black-and-white hatched, cross-hatched or symbolic patterns for emphasis. Authors who prefer to submit their line drawings electronically (which is preferred) may supply vector image files produced with Adobe Illustrator, CorelDraw or Freehand.

Photographs should be sharp and of good contrast preferably in the form of prints rather than transparencies or negatives. Do not place captions on any illustrations. Lettering should be capable of being reduced up to 60%.

Articles are normally published in black-and-white but it is possible to include colour illustrations at the author’s expense. Contact the Managing Editor to get information on current charges at

Illustrations previously published and unchanged from the original must be accompanied at the time of submission by permissions from the original publishers to republish. Getting permissions is the responsibility of the author, not Episodes


Tables with text only (without graphics) should preferably be presented as Word files but Excel format can also be accepted. They should be placed at the end of the manuscript or uploaded as separate files. There should not be more than one table on each page. The table caption in italic bold type must be placed above the table and should not end with a period.

An example is:

Table 1. Mechanical properties of soft clay

Clay Specific
< 5
w0 (%)
void ratio
wp (%)
wl (%)
2.69 61.5 90-95 2.35-2.46 30.0 62.5 32.5
2.70 45.3 47-53 1.25-1.34 22.5 39.2 16.7

(a)Mass percentage of particles with diameter smaller than 5 μm.

Footnotes should only be used if they are essential. These must be indicated in the text by a superscript lower case letter, in parenthesis, and ending with a period.


Acknowledgements should be included only if necessary, should be brief and placed at the end of the article and before the references. Grant or contribution numbers can be included.


Authors should take care to check the accuracy of their references and also that all citations in the text are properly reflected in the list of references (this is one of the main causes of amendments and delays to publication of papers). Examples of the Episodes “house styles” for references are:

The DOI number for a paper should be given at the end of the reference if available.

Theses and unpublished reports may be cited as references only if they are publicly available online. Otherwise they should be detailed in the acknowledgements. Papers that are in press can be cited. Papers that are at review should not be cited in the references but can be referred to as personal communications.

Biographical notes of authors

A brief biographical note (maximum 100 words) and a passport sized photograph of each author, up to a maximum of three, must accompany each article. If the number of authors of an article is greater than three a group photograph of all authors or passport sized photographs of three authors only are requested.


Appendices should not be included unless they are essential.


If any contribution is returned, rejected or withdrawn it can be improved and resubmitted. If so, the authors must provide the previous manuscript reference number and replies to any previous comments from reviewers and/or editor.
