Composition of the manuscript
- If your article is written in French, providing a title, an abstract and keywords in French AND in English is mandatory;
- If your article is written in English:
- Providing a title, abstract and keywords in English is mandatory
- We would also be grateful if you could provide us with a French translation of your title, abstract and keywords. If this metadata in French is not provided by the authors, the editorial team will automatically translate the English metadata.
Authors are asked to take particular care in the writing of their article, and will assume full responsibility for the spelling correction of their final text. Any article received in approximate English or French will be rejected immediately. Don't hesitate to use automatic spell-checkers, even free ones (e.g. DeepL Write, Grammarly or Antidote).
If neither English nor French is your mother tongue, please start by writing your article in your own language, then have it translated by a professional, or failing that, by automatic language processing software such as DeepL Translator or Google Translate. In all cases, please have your manuscript proofread by a native speaker or use a professional language editing service.
Authors are encouraged to write concisely.
This information is intended to ensure that your article is properly referenced (in databases and in future citations by other texts). It must include :
- A short but explicit title (please use colons ":" only to separate your title from any subtitle);
- The names of all the authors:
- giving their full first names,
- including an asterisk after the name of the author to whom correspondence and proofs should be sent;
- Contact details for all authors:
- professional e-mail address (it is essential to provide all these addresses in order to validate the submission of your manuscript),
- affiliation (if necessary, remember to have these affiliations checked by your supervisory institution before your article is sent to our layout department),
- full professional postal address for corresponding author only;
- An abstract for your article, no longer than 250 words;
- 3 to 7 kewords describing the subject of your article, so that it can be better indexed in international databases. Please use American spelling in English, and avoid general and plural terms and multiple concepts ("and" or "of", for example, should be avoided).
Please note that all this information must appear in the files submitted by the author and be entered (for the most part) in the journal's editorial software. In the event of discrepancies between the two sources, only the information entered in the editorial software will be taken into account.
Full text of the article
The body text of your article must be :
- double-spaced ;
- with numbered lines and pages;
- organised in clearly defined sections, numbered in Roman numerals and with their own headings:
- any sub-sections must also be numbered, explaining how they are arranged in the document: 1.1 (then 1.1.1, 1.1.2, etc.), 1.2, 1.3, etc.
- use this numbering for your internal cross-references (e.g. "see section 1.2.4") ;
- including figures, illustrations, graphs and tables where you want them to appear in your article, each accompanied by a caption (see below).
Your article must include certain sections:
- Declaration of interests: if you have no conflict of interest to declare, please include the following statement: "The authors do not work for, advise, own shares in, or receive funds from any organisation that could benefit from this article, and have declared no affiliation other than their research organisations" ;
- References: list of all bibliographical references included in your text (see below), excluding any other information (bibliographical or otherwise).
- Funding: indicate here, for each author concerned, the information relating to the funding specifically responsible for the results obtained (calls for projects and grants in particular), taking care to comply with the requirements of your funding body (e.g.: "This work has been supported by the European Research Council, as part of the Horizon Europe research programme - Grant Agreement n°[yyyy]. If the funding comes from a global grant (other than the funds allocated by the parent organisation in the ordinary course of research), simply indicate the name of the institute or organisation that provided the funding.
- Note: specify here whether your article is submitted at the invitation of the editorial committee, or if it is the result of a specific event (symposium, prize-giving ceremony, etc.).
Special sections in the text
- Acknowledgements: list here the people who provided you with help during your research (e.g. advice on your work, provision of data, spelling/typing correction, etc.). These acknowledgements should not be included on the title page, as a footnote to the title or otherwise, but collected in a separate section at the end of the article, before the references. They are distinct from specific funding information, which must appear in the bibliographic information.
- Dedication: a one-sentence dedication of the article may be included in a separate paragraph after the "Acknowledgements" section.
- Notes (endnotes or footnotes): present in the form of notes (numbered consecutively throughout the article) any additional information you would like readers to know, in particular to comment on certain references in the body of the text. Bibliographical information and the Declaration of interests, Acknowledgements, Dedication and References sections should not include notes of this type.
- Translated version of the article: it is possible to accompany the text of your article with a translation in any language using Latin characters. This translation will not be peer-reviewed, but it will be put online at the same time as the article, and thus made citable. Remember to specify the names and affiliations (and ORCIDs if available) of all the authors of this translation: if they are not indicated, the translation will have the same authors as the original version. You can also distribute it on a preprint server such as arXiv.
- Appendices: these will be posted online with the article as supplementary material. If you feel that they may be useful to readers in the form of full publications, feel free to put them online in a data warehouse such as Zenodo or on a preprint server such as arXiv.
The maximum length of the articles submitted to Comptes Rendus Géoscience is about 75 000 signs including spaces (an illustration counts for 2500 signs on average), that is to say the equivalent of 15 pages. This length can be exceeded only with the express agreement of the editors of the journal. If your manuscript exceeds this threshold, we may ask you to submit a new, shorter version.
The maximum length of comments and answers is limited to 2 pages, all inclusive.
NB: To find out the number of characters in your document, use the "Word Count" feature in Word
("Review" tab) or LibreOffice
All articles submitted for publication in Comptes Rendus Géoscience must be supported by reliable scientific sources. Manuscripts without bibliographical references will be rejected without evaluation.
In the body of the text
The sources underlying your article must all be mentioned in the body of your article, regardless of :
- when they were written or published ;
- their target audience (general public, amateurs, professionals, scientific community, etc.) ;
- their type (web page, journal article, book, conference proceedings, encyclopedia entry, dataset, image, source code, manuscript, archive document, etc.);
- their publication status (preprint, published article, etc.)
- if the cited document has not yet been accepted for publication, please cite the publicly available preprint,
- if the cited document has several versions (e.g. arXiv manuscripts, datasets, etc.), please specify which version you consulted at the time of writing,
- if your article is intended for inclusion in a special issue of Comptes Rendus, please wait until all your bibliographical references have been accepted for publication before citing them;
- the language in which they were written.
Please also mention the exact source of figures and illustrations (if not originals). For any photograph or image reproduction, please mention the original archive or publication, in addition to the source of the image itself.
Instructions for presenting references in the body of the text:
- Indicate the surname(s) of the author(s) in right square brackets, followed by the year of publication. If your reference has more than 3 authors, indicate only the first, followed by et al. e.g. [de Marsily et al. 2020] ;
- If you wish to cite several references at the same time, separate them with a semicolon and present them in alphabetical order of authors. E.g. [Chabaux 2021; de Marsily, 2018];
- If you cite several references by the same author published in the same year, assign a letter to each reference to distinguish them. E.g.: [de Marsily, 2020a; de Marsily, 2020b] ;
- If necessary, specify the exact pagination of the passage/figure referred to, bearing in mind that the overall pagination of the journal article or book chapter cited will appear in the final bibliography. E.g.: [Chabaux, 2021, p. 283] ;
- If you wish to add a bibliographical comment to your reference, present it in the form of a footnote or endnote.
All your article's primary and secondary sources must be included in a single final bibliography (not organized into subsets).
Your bibliography should be limited to the references mentioned throughout the text: any additional comments may appear in your manuscript as footnotes or endnotes, but not in the bibliography itself.
Instructions for presenting references in the final bibliography :
- Arrange your references in alphabetical order of the first author's surname, then in chronological order;
- Be sure to provide as much bibliographical information as possible: authors, title of article, title and number of journal, date of publication, pagination, publisher and city of publication for books, etc...;
- If you can, include the precise identifiers (DOI, handle, ARK...) of the documents cited, as well as their URLs;
- Don't worry about formatting (bold, italics, etc.): formatting will be done when you prepare the proofs;
- Ensure that all references cited in the text (including in the captions of illustrations, graphs and tables) are included in the bibliography.
- If you use bibliographic management software such as Zotero, feel free to submit your bibliography in .bib or .ris format at the same time as your article.

NB: Your bibliographic references will be reformatted by our editorial teams, so the examples above are not identical to the references you might find in our already published articles.
Equations and mathematical or chemical formulae
- Submit mathematical equations as editable text, not images;
- Submit simple formulas, in-line, with normal text whenever possible;
- Use solidus (/) instead of a horizontal line for small fractional terms, e.g., X/Y;
- Place exponents and subscripts carefully - so write x1 and not x1;
- Avoid ambiguous expressions such as 1/2x - so write either 1/(2x), or (1/2)x;
- Make sure that a given quantity is always designated by the same symbol in the same typeface - for example, a length L (written in italics) will not be called L elsewhere;
- Italicize mathematical or physical quantities, such as the x-axis or a m mass - thus distinguishing x+1 from x+l, and the logarithm ln from the product of l by n ;
- Indicate the powers of e by exp.;
- Number consecutively all equations that are to be displayed separately from the text (if explicitly mentioned in the text).
- Integrate your illustrations directly into your text and PDF files, in the best possible resolution (enlarged to 400%, your illustrations must not become blurred or pixelated);
- Label all your illustrations as figures and/or diagrams;
- Number your illustrations in Arabic numerals, in the order they appear in the article;
- Use consistent units and symbols between all illustrations and with the text;
- Use consistent lettering and dimensions for all original illustrations;
- Use Helvetica as the preferred font (if not available, use Arial, Courier, Times New Roman, Symbol or similar fonts) for text appearing in figures;
- Check that your illustrations will be adapted to a resizing on 75 mm width (single column), 160 mm for illustrations straddling two columns;
- Make sure that none of your illustrations exceed A4 size (210 x 297 mm);
- Make sure that the maximum size of your plates, also numbered in Arabic numerals and quoted in the text, is 220 mm in height and 160 mm in width;
- Ensure that photographs and halftones have good contrast;
- Make sure that the characters integrated in your illustrations remain legible even after reducing the size of the illustrations by 70%;
- Integrate the fonts used directly into your illustrations if the design software you use allows it;
- Provide a caption for each of your illustrations;
- Specify the exact source of your illustrations if they are not original works (citing the original work and any secondary works in which you have consulted reproductions, if necessary);
- Check that your illustrations are all cited in the body of the text.
Please use only royalty-free illustrations in your manuscript. If you wish to re-use an illustration protected by copyright (which may be the case for all images found on the internet using a search engine), please find out who the copyright holders are and obtain written authorisation to re-use it under a Creative Commons CC BY 4.0 license (see below).
If you also provide illustrations as separate files, please send them in the best possible resolution and choose image formats (JPEG, PNG, EPS, ChemDraw, Adobe Illustrator... - note that EPS format is not suitable for images containing text). When enlarged to 400%, your illustrations should not become blurred or pixelated.
- Use only one grid for each individual table, not one grid for each row;
- Align columns using tabs (not spaces) if your table does not have a grid;
- Number your tables in Roman numerals, in the order they appear in the article;
- Avoid vertical lines within tables;
- Accompany each table with a caption.
Conventions and abbreviations
Abbreviations should be defined in brackets the first time they are used in the text, with the exception of standard abbreviations. Units, symbols and nomenclature should follow international conventions (International System, IS). Standard units of measure and chemical symbols do not need to be defined in the text (the format m/s or m.s–1 are both acceptable, but should not be both used in the same article).
Open data policy
Authors wishing to publish in Comptes Rendus Géoscience are requested to provide all the files necessary for the formatting of their article in the most interoperable formats possible, in order to facilitate the work of the editors.
In order to encourage the free circulation of scientific knowledge, authors are strongly encouraged to accept the publication by Comptes Rendus Géoscience of these source files, together with the editorialized files. The dissemination of figures, in particular, especially when made available in an interoperable format and in high quality resolution, is a strong commitment to more open and robust science.
Research data includes all "materials in digital form, other than scientific publications, that are collected or produced in the course of scientific research activities and used as evidence in the research process, or that are commonly accepted by the scientific community as necessary to validate research findings and results" (source: EU Directive 2019/1024).
Authors wishing to publish in the Comptes Rendus Géoscience are encouraged to make all data related to the research work they describe in their manuscripts, and in particular the data directly underlying the submitted articles, freely available.
To do so, Comptes Rendus Géoscience strongly recommends that authors deposit their data in warehouses, i.e. databases specifically dedicated to the permanent preservation, enrichment and valorization of the materials they host. Datasets deposited in repositories are scientific productions that can be cited (in particular when they have a permanent identifier such as DOI), in the same way as a traditional publication.
It is recommended that authors release their data without embargo or after the shortest possible delay, in a way that allows their reuse, with an explicit link between the data and the underlying publication (reciprocal mention of the DOI). The journal encourages the provision of data under open licenses that allow their free reuse. Authors must use the licenses recommended by the repository where the data were deposited.
Reviewers of submitted articles may at any time request from authors the data underlying the results described. Failure to provide this data will result in the rejection of the submission.
NB: Research data should be as open as possible, but as closed as necessary. The Academy of Sciences and the editorial team of Comptes Rendus Géoscience cannot be held responsible for any failure to respect the rights associated with the exploitation or dissemination of the data underlying the articles published by the journal. Authors are invited to inquire about any intellectual or industrial property issues that may arise with their data.
To select a trusted repository appropriate for your data type or disciplinary area, consult the re3data directory. Check that the chosen repository meets quality criteria.
We should also mention Zenodo, a multidisciplinary data warehouse, supported by CERN and the European Commission. The data deposit is not moderated.
Authors who wish to publish in the Comptes Rendus Géoscience may attach to the full text of their submission additional files or material, independent of the body of the article but essential to its understanding. As this material is subject to the peer review process, it must be included and clearly marked as "Supporting Information for Electronic Publication" when the article is submitted. To ensure that your material is directly usable, please make sure that each file does not exceed 50 MB.
However, for reasons of technical constraints, valuation, preservation and reuse, authors are strongly advised to deposit this additional material in dedicated repositories, rather than publishing it as an appendix to the articles.
