Scope and Policy

The Brazilian Journal of Geology (BJG) is a quarterly journal published by the Brazilian Geological Society with an electronic open access version that provides an in-ternacional medium for the publication of original scientific work of broad interest concerned with all aspects of the earth sciences in Brazil, South America, and Antarctica, in-cluding oceanic regions adjacent to these regions. The BJG publishes papers with a regional appeal and more than local significance in the fields of mineralogy, petrology, geochemistry, paleontology, sedimentology, stratigraphy, structural geology, tectonics, neotectonics, geophysics applied to geology, volcanology, metallogeny and mineral deposits, marine geology, glaciology, paleoclimatology, geochronology, biostratigraphy, engineering geology, hydrogeology, geological hazards and remote sensing, providing a niche for interdisciplinary work on regional geology and Earth history.

The BJG publishes articles (including review articles), rapid communications, articles with accelerated review processes, editorials, and discussions (brief, objective and concise comments on recent papers published in BJG with replies by authors).

Manuscripts must be written in English. Companion papers will not be accepted.

The BJG follows the Code of Good Scientific Practice published by the São Paulo State Research Foundation – FAPESP, see

Authors should identify the sources of financial support for the research and/or preparation of the article and briefly describe the role of sponsor(s), if any, in study design; in the collection, analysis and interpretation of data; in the writing of the report; and in the decision to submit the article for publication.

Upon acceptance of an article, authors will be asked to complete a “BJG publishing agreement” transferring the copyright to the Brazilian Geological Society.

The BJG is an open access journal which means that all articles will be freely available to the wider public and that reuse will be permitted.

All authors are requested to disclose any actual or potential conflict of interest including any financial, personal or other relationships with other people or organizations that could inappropriately influence, or be perceived to influence, their work.


Submission of an article implies that the work described has not been published previously (except in the form of an abstract or as part of a published lecture or academic thesis), that it is not under consideration for publication elsewhere, that its publication is approved by all authors  as well as tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted, it will not be published elsewhere in the same form,  in English or in any other language, including electronically, without the written consent of the copyright-holder. Authors should verify the originality of the article by checking for plagiarism with any available software.
In addition, the corresponding author must state that:

  • The article has not been partitioned and that its con- tents are fully and independently understandable;
  • The article, edited in Microsoft Word, A4 format, does not exceed 12,000 words;
  • Each illustration or table is being sent in a separate file (.tif for figures);
  • No text or illustration file exceeds 10 Mb;
  • The authors are aware that submissions that do not comply with the “Instructions to authors” for BJG will be returned to the corresponding author;
  • The authors are aware that if reviewers indicate the need for major or minor revision, they will have 30 days to make the corrections suggested by the editors;
  • The authors are aware that they should carefully check and correct print proofs and return them to publishers within 48 hours to ensure the publication of the article without errors;
  • The authors are aware that, should the article be accepted for publication, copyright will be transferred to the Brazilian Geological Society by sending a letter signed by all authors (“BJG publishing agreement”).

Our online submission system (ScholarOne – SciELO) will guide you stepwise through the process of entering details on your article and uploading your files. The system will convert your article files to a single PDF file for use in the peer-review process. Editable fi- les (e.g., Word, LaTeX) are required to typeset your article for final publication. All correspondence, including notification of the Editor’s decision and requests for re- vision, will be sent by e-mail.

Peer review: Articles will be submitted to critical analysis by least two reviewers.
Type of evaluation: Authors will be identified in the manuscripts received by the Reviewers.


Form and preparation of manuscripts

Use of word processing software
Regardless of the file format of the original submission, at revision you must provide us with an editable file of the entire article. Keep the layout of the text as simple as possible. Most formatting codes will be removed and replaced on processing the article. The electronic text should be prepared in a way very similar to that of conventional manuscripts.

To avoid errors you are strongly advised to use the ‘spell-check’ and ‘grammar-check’ functions of your word processor.

Article structure
There are no strict formatting requirements, but all manuscripts must contain the essential elements  needed to convey your manuscript, for example, Abstract, Keywords, Introduction, Materials and  Methods,  Results, Conclusions, References, Artwork and Tables with Captions.

Divide the article into clearly defined and numbered sections. Subsections should be numbered 1.1 (then 1.1.1, 1.1.2, ...), 1.2, etc. (the abstract is not included in section numbering). Use this numbering also for internal cross-referencing: do not just refer to ‘the text’. Any subsection may be given a brief heading. Each heading should appear on its own separate  line.

State the objectives of the work and provide an adequate background, avoiding a detailed literature survey or a summary of the results.

Material and methods
Provide sufficient detail to allow the work to be re- produced.    Methods    already    published    should    be indicated by a reference. Only relevant modifications should be described.

A Theory section should extend, not repeat, the back- ground to the article already dealt with in the Introduction and lay the foundation for further work. In contrast, a Calculation section represents a practical development from a theoretical basis.

Results should be clear and concise.

This should explore the significance of the results of the work, not repeat them. A combined Results and Discussion section is often appropriate. Avoid extensive citations and discussion of published literature.

The main conclusions of the study may be presented in a short Conclusions section, which may stand alone or form a subsection of a Discussion or Results and Discussion section.

If there is more  than  one  appendix,  they  should be identified as A, B, etc. Formulae and equations in appendices should be given separate numbering: Eq. (A.1), Eq. (A.2), etc.; in a subsequent appendix, Eq. (B.1) and so on. This also applies to tables and figures: Table A.1; Fig. A.1, etc.

Essential title page information

Title. Concise, informative, and interesting. Titles are often used in information-retrieval systems. Avoid abbreviations and formulae where possible.

Author names and affiliations. Please clearly indicate the given name(s) and family name(s) of each author and check that all names are accurately spelled. Present the authors’ affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript number immediately after the author’s name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name and, if available, the e-mail address of each author.

Corresponding author. Clearly indicate who will handle correspondence at all stages of refereeing, publication, and post-publication. Ensure that the e-mail address is given and that contact details are kept up to date by the corresponding author.

Present/permanent address. If an author has moved since the work described in the article was done, or was visiting at the time, a ‘Present address’ (or ‘Permanent address’) may be indicated as a  footnote to that author’s name. The address at which the author actually did the work must be retained as the main, affiliation address. Superscript Arabic numerals are used for such footnotes.

A concise and factual abstract is required. The abstract should state briefly the purpose of the research, the principal results and major conclusions. An abstract is often presented separately from the article, so it must be able to stand alone. For this reason, References should be avoided, but if essential, then cite the author(s) and year(s). Also, non-standard or uncommon abbreviations should be avoided, but if essential they must be defined at their first mention in the abstract itself.

Immediately after the abstract, provide a maximum   of 6 keywords, using American spelling and avoiding general and plural terms and multiple concepts (avoid, for example, ‘and’, ‘of ’). Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible. These keywords will be used for indexing purposes.

Define abbreviations that are not standard in this field in a footnote to be placed on the first page of the article. Such abbreviations that are unavoidable in the abstract must be de- fined at their first mention there, as well as in the footnote. Ensure consistency of abbreviations throughout the article.

Collate acknowledgements in a separate section at the end of the article before the references and do not, there- fore, include them on the title page, as a footnote to the title or otherwise. List here those individuals who provided help during the research (e.g., providing language help, writing assistance or proof reading the article, etc.), as well as institutions and funding agencies.

Follow internationally accepted rules and conventions: use the international system of units (SI). If other units are mentioned, please give their equivalent in SI.

Math formulae
Please submit math equations as editable text and not as images. Present simple formulae in line with normal text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, e.g., X/Y. In principle, variables are to be presented in italics. Powers of e are often more conveniently denoted by exp. Number consecutively any equations that have to be displayed separately from the text (if referred to explicitly in the text).

Electronic artwork

General points

  • Make sure you use uniform lettering and sizing of your original artwork.
  • Preferred fonts: Arial (or Helvetica), Times New Roman (or Times), Symbol, Courier.
  • Number the illustrations according to their sequence in the text.
  • Use a logical naming convention for your artwork files.
  • For Word submissions only, you may provide figures, their captions, and tables within a single file at the revision stage.

Regardless of the application used, when your electronic artwork is finalized, please ‘save as’ or convert the images to one of the following formats (note the resolution requirements for line drawings, halftones, and line/halftone combinations given below):

  • EPS (or PDF): Vector drawings. Embed the font or save the text as ‘graphics’.
  • TIFF (or JPG): Color or grayscale photographs (half- tones): always use a minimum of 300 dpi.
  • TIFF (or JPG): Bitmapped line drawings: use a mini- mum of 1000 dpi.
  • TIFF (or JPG): Combined bitmapped line/half-tone (color or grayscale) images: a minimum of 500 dpi is required. Please do not:
  • Supply files that are optimized for screen use (e.g., GIF, BMP, PICT, WPG); the resolution is too low.
  • Supply files that are too low in resolution.
  • Submit graphics that are disproportionately large for the content.

Color artwork
Please make sure that artwork files are in an acceptable format — TIFF (or JPEG), EPS (or PDF), or MS Office files — and with the correct resolution. If, together with your accepted article, you submit usable color figures, the- se will appear in color online.

Figure captions
Ensure that each illustration has a caption. A caption should comprise a brief title (not on the figure itself ) and a description of the illustration. Keep text in the illustrations to a minimum, but be sure to explain all symbols and abbreviations used.

Please submit tables as editable text and not as images. Tables can be placed either next to the relevant text in the article, or on separate page(s) at the end. Number tables consecutively in accordance with their appearance in the text and place any table notes below the table body. Be spa- ring in the use of tables and ensure that the data presented in them do not duplicate results described elsewhere in the article. Please avoid using vertical rules.

Citation in text
Please ensure that every reference cited in the text is also present in the reference list (and vice versa). Any references cited in the abstract must be given in full. Unpublished results and personal communications are not recommended in the reference list, but may be mentioned in the text. If these references are included in the reference list they should follow the standard reference style of the journal and should include a substitution of the publication date with either ‘Unpublished results’ or ‘Personal communication’. Citation of a reference as ‘in press’ implies that the item has been accepted for publication.

Web references
As a minimum, the full URL should be given and the date when the reference was last accessed. Any further in- formation, if known (DOI, author names, dates, reference to a source publication, etc.), should also be given. Web references can be listed separately (e.g., after the reference list) under a different heading if desired, or can be included in the reference list.

Reference formatting
There are no strict requirements on reference format- ting at submission. References can be in any style or format as long as the style is consistent. Where applicable, name(s) of author(s), journal title/book title, chapter title/article title, year of publication, volume number/book chapter and the pagination must be present. Use of DOI is highly encouraged. The reference style used by the journal will be applied to the accepted article by SCIELO at the proof stage. Note that missing data will be highlighted at proof stage for the author to correct.

Reference style
All publications cited in the text should be presented in a list of references following the text of the manuscript. In the text refer to the author’s name (without initials) and year of publication  (e.g.  “Since  Almeida  (1986)  has shown that...” or “This is in  agreement  with  results obtained later (Trompette 1994; Heilbron and Machado 2003).”
For three or more authors use the first author followed by “et al.”, in the text. The list of references should be arranged alphabetically by authors’ names. The manuscript should be carefully checked to ensure that the spelling of authors’ names and dates are exactly the same in the text as in the reference list.
References should be given in the following form:
