Information for Authors
Overview and Editorial Policy
Geochemical Perspectives Letters is published by the European Association for Geochemistry (EAG), produced by and for the geochemical community. It is open access, without page charges (unless opting for the Open Access Contribution) and available in electronic format. Members of the EAG receive the paper version as part of their membership.
Articles should be short (max. 3000 words including abstract, text, figure captions and references, and no more than 4 tables or figures), top quality and report on new, interesting developments. If desired, supporting information can be included as a Supplementary Information, to be published online only.
Articles will only be published if they are original work, not previously published or not under consideration for publication elsewhere.
All manuscript submissions are subject to initial appraisal by an editor, and if suitable for the journal, will follow a standard peer-review process.
Manuscripts should be submitted using the online tool. They will be assigned an editor and reviewed as quickly as possible.
Should you have any issue with the tool, please contact firstname.lastname@example.org.
The cover letter should briefly describe the importance of the manuscript for geochemistry and provide the names of 2 editors and 4 reviewers, with no association to the author(s). Reviewers cannot be former supervisors (within 5 years of PhD), current or past close collaborators, or from the same institution. Should authors, reviewers or editors have any conflict of interest, this should be stated in the cover letter.
Article Length and Style
An article consists of no more than 3000 words, including abstract, text, figure captions and references as well as a maximum of 4 small figures or tables. In the printed form, it should cover no more than 10-12 pages in A5 format.
Make sure your submission includes line numbers.
Please use British English spelling, grammar and style. We strongly recommend setting the language to English UK in the text editor.
Define technical terms and avoid jargon.
TitleThe title should be short, punchy, and communicate the main findings of the article in less than 90 characters.
The submitting author should list all the names and affiliations of the co-authors. The corresponding author(s) should be identified with an asterisk.
Abstract and Graphical Abstract
The abstract should be concise (150-180 words) but informative, telling what was done, how it was done, what was observed, what it means and what major, new understanding it has produced.
Authors should also submit a graphical abstract summarising the message of the article; the graphical abstract should ideally be a good representation of the story in the paper and also be useful for advertisement. If a diagram is used as graphical abstract, we may also request a photo for advertisement.
The final size of the graphical abstract in the html version of the article will be 175 px wide and maximum 150 px high. If your image includes text, make sure that it remains legible at that size.
Formatting of the Text
To facilitate creation of camera ready copy, articles should be written using MS Word, in 12 pt Times New Roman; the submission tool will produce a PDF but if your article is accepted for publication, the Word document may be requested.
Leave one empty line between paragraphs. Do not indent paragraphs.
Headers and sub-headers should be clearly identifiable, in the main article as well as in the Supplementary Information.
Use standard SI units. Use units without punctuation and with appropriate spacing, i.e. leave a space between the unit and the quantity; for example, 7 Myr, 25 °C, 10 %.
Leave a space on each side of mathematical symbols; for example, x + y, P < 3.
However if there is only one number, remove the space; for example, <3.
Use the abbreviation Myr for million years; Ma for Megaannum.
Note "i.e." and "e.g." should always be in italics. In British standards, "e.g." should be followed by a comma but not "i.e.".
In numbers of 5 digits and more, use commas to separate off the thousands and millions.
Define parameters used in mathematical expressions. Use variables compatible with journals commonly used by geochemists (American Mineralogist, Canadian Mineralogist, Chemical Geology, Earth and Planetary Science, Mineralogical Magazine, Geochimica et Cosmochimica Acta or Clays and Clay Minerals).
Indicate equations as Eq. 1, Eq. 2 etc. If equations are used in the Supplementary Information, indicate them as Eq. S-1, Eq. S-2 etc.
We follow the recommendations of the International Mineralogical Association regarding mineral nomenclature.
Figures and Tables
Note authors are responsible for requesting permission to reproduce previously published works.
Take advantage of the possibility to publish in colour; interesting, colour graphics are strongly encouraged.
Use tif, jpeg, png or eps format and save them in RGB or CYMK. Do not send figures embedded in other software.
Use high resolution photographs (300 dpi at published size) or line drawings (preferably coloured) at 600 dpi. Pictures from a website or a PowerPoint file are unlikely to be adequate for printing.
Do not add frames to figures.
Use British English spelling for any text on the figures.
If the figure includes several panes, those should be indicated as "a, b, c..." in lower case. The size of the characters should be sufficiently big to ensure legibility.
Citing figures in the text
Figures in the text should be cited as "Figure 1 presents…" or "Figure 1a presents...".
If parenthesis are used, the figure should be cited as "(Fig. 1)" or "(Fig. 1a,b)".
Figures in the text of Supplementary Information should be cited as "Figure S-1" or "(Fig. S-1)".
Format of figure captions
The figure caption should be written as: "Figure 1 Concentration as a function... ".
If the figure includes several panes, the caption should be written as: "Figure S-2 (a) Complete cases (black) versus imputed (red) kernel density distributions for TiO2. (b-c) Overall, the imputed values are realistic and do not affect the secular trends that are the focus herein."
Tables should be named "Table 1" etc. Tables in Supplementary Information should be named "Table S-1".
Authors can submit Supplementary Information (SI) supporting the main article's conclusions. The SI will be subject to the same editorial and peer-review procedures as the main article and may include details of experimental or field protocols, description of computational analyses, additional figures, tables, movies and references. The SI will only be published online but in the printed version of Geochemical Perspectives Letters, a note at the end of the article will highlight the SI.
Author Contributions and Acknowledgements
The description of the contribution of each co-author is optional, but if included, should be described briefly.
Acknowledgements are optional, and if added, should remain concise.
References should be included in the text with names and dates, not by footnote numbers.
Articles that are not published cannot be referenced so do not include any reference to unpublished articles.
Authors are responsible for the accuracy of the references used.
Citing references in the text
References in the text should be cited as such: "Based on modelling of Fitoussi and Bourdon (2012), we calculate...".
If cited in parenthesis: "The bulk Earth Zn isotope composition is equal to or lighter than those same meteorites (Albarède, 2009; Chen et al., 2013)...".
Grouped references should be listed first chronologically, then alphabetically and separated by a semicolon: "(Smith, 1952; Jones, 1969; Smith and Jones, 1975, 1980; Hansen, 2010; Jakobsen et al., 2010)".
Note "et al.." should be in italics.
Format of references in the reference list
In the reference list, all the names of the authors should be listed and the titles of publications should be entered in full and in italics, as per the examples below.

Open Access Contribution
When articles are accepted for publication, authors will be given the option to publish at no charge OR to make an Open Access Contribution of 1000 Euros (articles will be open-access either way). Contributions received will be directly attributed to covering some of the expenses associated with producing Geochemical Perspectives Letters, a fully open-access publication created by and for the geochemical community.
Should your institution or funding body have established funds to help support open-access publication, please consider selecting the Open Access Contribution. If required by funding bodies, authors may then distribute the articles under Creative Commons Attribution 4.0 License (CC BY 4.0). See Copyright and License for more information.
