Manuscript preparation : General guidelines
The main text document should be submitted in a standard editable format, compatible with MS Word (preferably .doc, .docx or .rtf).
Tables should be included in the main manuscript at their correct place in editable text (not as image);
Authors must not embed image files within their manuscript. Each figure must be provided as a separate file with sufficiently high resolution to be reproduced (at least 300 dpi for photos and 600 dpi for vector graphics);
Manuscripts must use correct scientific English ('spell checked' and 'grammar checked');
Math formulae should be inserted as editable text and not as images. Simple formulae should be given in line with the text wherever possible;
In all cases, sufficient detail must be provided to allow the work to be reproduced.
All references mentioned in the Reference List must be cited in the text, and vice versa;
It is the responsibility of the authors to obtain permission to reproduce copyrighted material from other sources (including the internet);
A competing interest statement must be provided, even if the authors have no competing interests to declare;
Authors should provide referee suggestions with contact details (E-mail).
Manuscript preparation : Style guidelines
Manuscripts should be compiled in the following order:
full names of authors and their affiliations;
competing interest statement;
figure caption(s) (as a list).
There is no strict formatting requirement for the main text but all manuscripts must contain the essential elements: Introduction, Materials and Methods, Results, Discussion and Conclusions.
Length: there is no limitation to the length of manuscripts in terms of words or figures at CRPP but authors should try to remain as concise as possible.
The text in the submitted manuscript has to be double-spaced. Each line and each page must be numbered.
In order to help the Editors to format the manuscript, the references included in the text and the calls of figures/tables should be highlighted (for example, in another color font).
Abbreviations must be defined at their first mention directly in the text or in a devoted section (no footnotes allowed).
Title: It should be concise and informative.
Author names and affiliations: All authors of the manuscript must include their full names and affiliation(s) on the first page of the manuscript. All affiliations should be indicated with a lowercase superscript letter immediately after the author's name and in front of the appropriate full address (including the full postal address with the country name and the e-mail address). One author should be clearly identified as the corresponding author who acts on all behalf of co-authors in all matters of the publication process and after publication (for example ‘*: corresponding author’).
All persons who have a reasonable claim to authorship must be named in the manuscript as co-authors, and the order of names should be agreed upon by all authors.
Abstract: A concise and factual abstract of up to 300 words is required. The abstract should state briefly the purpose of the research, the principal results and major conclusions; no references are allowed in the abstract; if non-standard abbreviations are absolutely necessary, they must be defined at first mention in the abstract itself.
Keywords: Each manuscript should have 4 to 6 keywords (avoiding multiple concepts). We remind authors that words that are already comprised in the title and the abstract of the paper are automatically considered as keywords in most search engines. Hence, the choice of keywords should rather be on terms that are not already mentioned in these items.
Introduction: The introduction chapter provides an adequate background, history of research in the specific topic and states the objectives of the work.
Conclusion: The conclusion chapter is mandatory and should be the object of the greatest attention by the authors.
Declaration of interest: Authors must disclose any interests (i.e., financial interest, personal relationships with people or organizations that could bias their work) as a summary declaration of interest statement in the manuscript file, before the acknowledgments. If there are no interests to declare then please state this: ‘Declarations of interest: none’.
Author contributions: Must include a statement that specifies the contribution of every author. Authors should be denoted by initials. If multiple authors share the same initials, distinguish between them by using their family names. Consider contributions in terms of research design, concepts and ideas, lab analysis, data treatment, funding, supervision, writing and editing. Funding alone is not sufficient for an author contribution.
Data availability: All manuscripts reporting original research must include a data availability statement. We invite the authors to submit their original dataset in the repository of their choice, provide the link to the repository and ensure that data will always remain available on that link. Authors are thus encouraged to get a DOI for their dataset. Alternative solutions are to place the data under the form of a table in the supplementary information, providing that it does not exceed 2,000 lines, or uploaded and made available on the CRPP website as an appendix, in which case we recommend the first line of the data table to be used for a clear description. No manuscript using original dataset(s) will be accepted without making these datasets available in a data repository, supplementary information or table in appendix. Tables should be rather shared under the form of .txt or .csv files.
Acknowledgements: The acknowledgements section is placed at the end of the article before the references. It should list all people or organizations that provided help during the research (e.g., language or writing assistance, field assistance, etc.). If the name of any of the reviewers is known, it should be added in the acknowledgements for his/ her contribution; if the referees remain anonymous, they should be acknowledged as ‘anonymous reviewers’.
Funding: A list of every funding source or grant that supported the work (if relevant) must be included in the acknowledgements section.
Symbols, numbers, dimensions and units: Authors must adhere to SI units. Units are used without a full stop and are not italicized. Numbers should take the English format. We recommend the use of yr, kyr, myr for duration whereas the use of a, ka, Ma and Ga should be preferred for time units. Example: “Our filter output delineates 10 cycles of 100 kyr between 435 and 436 Ma”.
Sections: The article should be divided into clearly defined sections and section headings (on a separate line) should be concise and explicative. Sections have to be numbered 1., 2., etc., subsections 1.1., then 1.1.1. (the abstract and key-words are not included in section numbering). This numbering should also be used for internal cross-referencing.
Figures: All figures must be numbered in the order in which they appear in the manuscript (e.g., Figure 1, Figure 2A-B);
Component parts of figures included in the text should be labelled using cap letters, e.g., A, B, C. The caption of the figure should refer clearly to each individual panel.
Full page figure are allowed in CRPP;
The filename for a figure should be, e.g., Figure 1;
Figures should be prepared with a white background (rather than a black background);
The lettering in figures and plates should be in a standard sans serif font, such as MS-sans-serif or Arial;
Maximum size for a plate or a figure is up to a maximal size of 18 cm width and 26 cm height;
Figures should be designed to make good use of the space;
Special attention will be given to the quality of figures by the Editors. Authors must provide the highest quality figure format possible; figures of insufficient quality will be rejected. Photographs should not be too high-contrast or fuzzy. Color is accepted;
Rainbow gradients (for example the “jet” surface colormap in Matlab®) are problematic: see the paper by Crameri et al. (2020). Instead, for colormaps in figures, we recommend to use either more simple color gradients or alternative gradients such as available on the following links:
Figures must be submitted as individual files (one per figure, never in the manuscript file itself), preferably as standard SVG file format (scalable vector graphics) with images included directly (not as a link) when usable. TIFF (tagged image file format), or uncompressed JPEG are also acceptable;
Figure captions are placed in the main file, following the text of the manuscript;
In all cases, scale bars are preferred instead of magnification factors, as the figures may require resizing.
For bibliography entries (in alphabetical order), use the APA standard:

Use of DOI is highly encouraged (http://search.crossref.org).
Internet websites must to be referenced under APA standard:
Author Last Name, F. M. (published date). Title of the article. Retrieved from http://. Date of access.
Reference style in text:
Author Last Name, Year Of Publication
First Author Last Name and Second Author Last Name, Year Of Publication
First Author Last Name et al., Year Of Publication
Groups of references should be listed first alphabetically, then chronologically, in the same order in which they appear in the reference list. The citations should be separated with semicolons. Letters (a, b, c etc.) should be used to separate works with the same authors and year of publication.
Supplementary Information and Appendices
Use “Supplementary Information” for a compiled pdf file providing additional figures and any additional support information to the paper. Appendices should rather be used for items such as data tables. If there is more than one appendix, they should be identified using letters A, B, etc.
