Manuscript Guidelines

Publication policy

The South African Journal of Geology (SAJG) publishes scientific papers, notes, stratigraphic descriptions and discussions in the broadly defined fields of geoscience that are related directly or indirectly to the geology of Africa. Contributions relevant to former supercontinental entities such as Gondwana and Rodinia are also welcome as are topical studies on any geoscience-related discipline. Review papers are welcome as long as they represent original, new syntheses. Special issues are also encouraged but terms for these must be negotiated with the Editors.

All contributions to the SAJG are subjected to peer-review by geoscientists selected by the Scientific Editor or members of the Editorial Board. The principal criteria used to evaluate contributions are …

1. The contribution must present scientific findings that are original, i.e., they must not have appeared elsewhere and must not be under consideration by any other publication.

2. The contribution must be scientifically constrained, i.e., any interpretations made or conclusions drawn must be based on the objective evaluation of scientific data.

3. There must be effective separation of scientific facts and observations from interpretations and inferences.

4. The article should make a contribution toward our deeper understanding of Earth processes, broadly defined.

Copyright in papers published by the SAJG is vested in the Geological Society of South Africa (GSSA). The language of the SAJG is English. The SAJG version of record is the electronic (i.e., digital) collection archived at GeoScienceWorld. A freely accessible repository for Supplemental Data exists at GSSA.

Stratigraphic descriptions should conform to criteria defined by the South African Committee for Stratigraphy (SACS).

Papers are generally limited to 40 double spaced A4 size typed pages including text, references, figures and tables.

Notes are regarded as short papers on topical issues and every attempt will be made to publish them quickly. They should not exceed 4 printed pages including text, references, figures and tables.

Discussions represent a forum in which previously published papers that appeared in the SAJG can be disputed, clarified and/or discussed. Replies to such discussions will be invited from the original authors. Discussions must be submitted as soon as possible and not longer than six months after publication of the original paper.

Early publication

Early publications are peer-reviewed articles that have been accepted for publication in the South African Journal of Geology (SAJG) and are in corrected proof format.

Although early publications do not have final bibliographic details (e.g., volume, issue number and page numbers must be added), they should be cited using the year of online publication and the DOI. The correct format would thus include the authors, title, year of online publication, and DOI.

When the article is assigned to a specific issue of the SAJG it will be allocated page numbers in that issue and the Early Publication version will be removed from the online platform. The year an article was first published online will be carried over to the final volume and issue.

Copyright for articles published as early publications of the SAJG is vested in the Geological Society of South Africa (GSSA).

Submission of manuscripts

Manuscripts including references should be typed double space and in 12 font size. All pages should carry the authors' name and be properly numbered.

Authors are encouraged to include with their submissions the names and email addresses of persons they deem suitable to be referees of their manuscript. At their discretion, the Scientific Editor and members of the Editorial Board may use them.

For peer-review purposes, manuscripts should be submitted by email to the Scientific Editor Prof. Marlina Elburg (marlinae@uj.ac.za and copied to sajg@gssa.org.za) as a single PDF file of no more than 5 MB (megabytes).

Preparation of manuscripts for review

Manuscripts for review should be submitted double-spaced in the style of the SAJG, and authors are requested to consult a recent issue not older than Volume 118, Number 4 for the publication layout (of the PDF and print format).

The title page should include the title of the manuscript, initials, surname, affiliation and email address of each author and corresponding address. A short summary of the paper should be provided as the abstract. Avoid using deferring phrases such as "…is discussed" and include no references.  Remember that your abstract may be the only part of your paper that is read so it should help readers to become quickly informed about your results and to decide if your paper is relevant to their interests. Abstracts from the SAJG are circulated by international retrieval systems.

The text or main body of the manuscript should be logically organized into sections but please avoid overuse of subsection constructs. There must be a clear separation of facts and observations from interpretations and inferences. An alphabetical and then chronological list of all references cited should follow the main text.

The format of references must follow that of the SAJG and can be obtained in any issue not older than Volume 118, Number 4; and the names of journals must be spelled out in full. Papers "in preparation" and "submitted" cannot be used as references. Please make a careful crosscheck of the reference list against citations in the text.

Tables should be compiled on separate sheets and designed to fit across a single or double column width on a single journal page. Use of decimal points, rather than commas, is required for all reported numbers.

Illustrations must be legible and contain only relevant information. Place names and other locations mentioned in the text must appear clearly on maps.

Clear instructions must be provided on how mathematical symbols and equations should be printed.  For Greek and non-Roman letters, authors must identify the symbol in words the first time it is used.

Receipt of manuscripts will be acknowledged by email.

Submission of revised manuscripts

Revised manuscripts should be returned to the Scientific Editor in electronic format either as email attachments or via Dropbox or similar service. In a cover letter, the authors must explain in detail how they dealt with each of the referees' comments and suggestions.

The text should be in Word format and tables in Excel worksheets. Photos, figures and illustrations must not be embedded in Word files.

Photos, figures and illustrations should be submitted separately as uncompressed TIFF files, which should have minimum resolutions of 300 dpi for colour, 600 dpi for greyscale and 1200 dpi for black and white. Colour in photos, figures and illustrations should be RGB (rather than CMYK), with supporting text to be in one colour, 100% black (and not in RGB or CMYK). There will be no charge for colour photos, figures and illustrations in either the electronic version of the Journal at GeoScienceWorld, or in the printed version of the Journal.

Authors will receive copies of their articles as high quality PDF files. No reprints will be provided.
