Aims and Scope

Geochemical Journal is an international open access journal devoted to original research papers in geochemistry and cosmochemistry. It is the primary peer-reviewed journal of the Geochemical Society of Japan.

Areas of research are as follows:

  • Cosmochemistry and Planetary Geochemistry
  • Mineral and Rock Chemistry
  • Volcanology and Hydrothermal Chemistry
  • Isotope Geochemistry and Geochronology
  • Atmospheric Chemistry
  • Hydro- and Marine Chemistry
  • Organic Geochemistry
  • Environmental Chemistry
  • Biogeochemistry
  • New Methods in Geochemistry

Papers published in the journal are scientifically original and novel, exploring unique and important ideas or describing important developments in geochemistry and cosmochemistry. They have broad, rather than local, significance and interest to the journal’s global audience of researchers, engineers and students.

Manuscript Types

The journal welcomes six manuscript types, all of which are subject to peer review.

Invited Reviews

Invited Reviews provide summaries of scientific progress in selected frontier fields and provide new interpretation. The aim of Invited Reviews is to enhance understanding and to promote interaction among researchers of the major fields of the geochemical community. The Editor exclusively solicits Invited Reviews; unsolicited Reviews are not considered.


Articles are the principal mode of reporting research. They present important new results and deal with major studies that address a significant area of interest to the readers. They should be as concise as possible. Large tables should be submitted as Supplementary Material.


Notes are short reports intended mainly for data presentation that benefit the geochemistry community. Short papers dealing with new ideas and/or new experimental methods are also considered as Notes. Text should not exceed 1500 words. Tables, if required, must be included as Supplementary Material.

Express Letters

Express Letters are short, timely papers which report a new idea, experimental method, discovery, or invention. They should not exceed 6 printed pages or approximately 5,500 words, but including all tables, figures and references. The editors will assist in the rapid publication of Express Letters, and papers of this category are normally published within two months of submission.


Data articles are analytical reports, databases, and compilations of valuable geochemical data and datasets (databases), which are of international interest to the geochemical research community and contribute to the development of the field. New scientific discoveries are not required to be reported, but manuscripts must provide scientifically meaningful and reliable datasets.

The introduction must provide background of the data, database and potential benefits. Methods should include detailed analytical procedures, experimental design, and computational calculation that are readily reproducible. Technical validation and statistical processing of data or other data processing criteria must be described to provide measures of quality control; examples are the statistical analyses of experimental error and variation. The Results and Discussion should include chemical compositions and isotope ratios of internationally available geochemical reference materials or alternative reference materials to allow for the evaluation of the accuracy of the data.

It is highly recommended that a discussion of the applications of the given datasets is included. The following items are optional, but would be informative: (i) usage notes of the datasets to assist researchers, such as information on database design, structure, contents, and uniform resource locator (URL), (ii) file format, and (iii) instructions for users. Large tables and supportive figures should be submitted as a part of any Supplementary Material.

The submitted manuscript is reviewed in terms of the value of the data and its utility. In particular, the validity and robustness of experimental and observational procedures, data generation processes, and statistical processes are reviewed by specialists.

Critical Comments

Critical Comments examine issues raised by previously published articles in Geochemical Journal. The authors of the original article are given the opportunity to reply. Critical Comments and replies are reviewed and edited as per Articles.

Special Issues

Collections of papers on a particular topic can be published in a Special Issue with the agreement and collaboration of the journal’s Executive Editor.

Journal & Ethics Policies

Geochemical Journal upholds the highest standards in scholarly publishing.

Before submitting a manuscript to the journal, authors must ensure that they have read and complied with the journal’s policies. The journal reserves the right to reject without review, or retract, any manuscript that the Editor believes may not comply with these policies.

The responsibilities of the journal’s authors, editors, reviewers and publisher regarding research and publication ethics are described in full below.

Submission to the journal implies that the manuscript has not been previously published (in part or in whole, in any language), is not in press, and is not under consideration for publication elsewhere.

Authors must inform the editors if any related manuscripts are under consideration, in press or published elsewhere. The availability of a manuscript on a publicly accessible preprint server does not constitute prior publication (see ‘Preprints’).

If authors choose to submit their manuscript elsewhere before a final decision has been made on its suitability for publication in Geochemical Journal, they should first withdraw it from the journal.


Geochemical Journal welcomes manuscript submissions from authors based anywhere in the world.

Submission of a manuscript to the journal implies that all authors have approved it, warrant it is factual, have agreed to its submission, and have the right to publish it.


Submission to the journal implies that the manuscript is original work. The journal may use iThenticate plagiarism software to screen manuscripts for unoriginal content. By submitting a manuscript to the journal, authors agree to this screening. Any manuscript with an unacceptable level of unoriginal material may be rejected or retracted at the editors’ discretion.


To support the wide dissemination of research, the journal encourages authors to post their research manuscripts on community-recognized preprint servers, either before or alongside submission to the journal. This policy applies only to the original version of a manuscript that describes primary research. Any version of a manuscript that has been revised in response to reviewers’ comments, accepted for publication or published in the journal should not be posted on a preprint server. Instead, forward links to the published manuscript may be posted on the preprint server.

Authors should retain copyright in their work when posting to a preprint server.


When assessing the novelty of a manuscript submitted to the journal, the editors will not be influenced by other manuscripts that are posted on community-recognized preprint servers after the date of submission to Geochemical Journal (or after the date of posting on a preprint server, if the manuscript is submitted to the journal within 4 months).


Submission to the journal implies that all authors have seen and approved the author list. Changes to the author list after manuscript submission – such as the insertion or removal of author names, or a rearrangement of author order – must be approved by all authors and the editor.

Authors are encouraged to consider the Council of Science Editors (CSE) principles governing authorship. According to the CSE guidelines (and references therein), each author is expected have made substantial contributions to the conception or design of the work; or the acquisition, analysis or interpretation of data; or have drafted the work or substantively revised it. Authors have also agreed to be held accountable for their own contributions to the work; can identify which co-authors are responsible for other parts of the work; have confidence in the integrity of the work; and have reviewed and approved the final manuscript and any resubmissions. Contributors who do not qualify for authorship may be included in the Acknowledgments section instead. The corresponding author is responsible for ensuring that all authors abide by and agree to the journal’s policies on authorship.

Image integrity

Authors may digitally manipulate or process images, but only if the adjustments are kept to a minimum, are applied to the entire image, meet community standards, and are clearly described in the manuscript. All images in a manuscript must accurately reflect the original data on which they are based. Authors must not move, remove, add or enhance individual parts of an image. The editors reserve the right to request original, unprocessed images from the authors. Failure to provide requested images may result in a manuscript being rejected or retracted.

Reproducing copyrighted material

If a manuscript includes material that is not under the authors’ own copyright, the authors must obtain permission from the copyright holder(s) to reproduce it.

If a manuscript includes previously published material, the authors must obtain permission from the copyright owners and the publisher of the original work to reproduce it. The authors must cite the original work in their manuscript.

Copies of all reproduction permissions must be included with the manuscript when it is first submitted.

Availability of data and materials

Authors must disclose the source of publicly available data and materials, such as public repositories or commercial manufacturers, by including accession numbers or company details in their manuscript, as appropriate.

Authors may make their own data and materials available in Supplementary Material, or by linking from their manuscript to relevant community-recognized public databases or digital repositories. All data sets must be made available in full to the editors and reviewers during the peer review process, and must be made publicly available by the date of publication. Authors commit to preserving their data sets for at least ten years from the date of publication in the journal.

The journal encourages authors to grant reasonable requests from colleagues to share any data, materials and experimental protocols described in their manuscript.

Specimen collection

Manuscripts describing the collection of archaeological, geological, paleontological or wildlife specimens or samples should include detailed information on their provenance and collection methods. Authors must include a statement in their manuscript describing the relevant ethics guidelines, local laws and collection permits under which the research was conducted.

Author competing interests and conflicts of interest

In the interests of transparency, the journal requires all authors to declare any competing or conflicts of interest in relation to their submitted manuscript. A conflict of interest exists when there are actual, perceived or potential circumstances that could influence an author’s ability to conduct or report research impartially. Potential conflicts include (but are not limited to) competing commercial or financial interests, commercial affiliations, consulting roles, or ownership of stock or equity.

Authors should list all funding sources for their work in the Acknowledgments section of their manuscript.


The journal maintains the confidentiality of all unpublished manuscripts. By submitting their manuscript to the journal, the authors warrant that they will keep all correspondence about their manuscript (from the Editorial Office, editors, and reviewers) strictly confidential.

Self-archiving (Green Open Access) policy

Self-archiving, also known as Green Open Access, enables authors to deposit a copy of their manuscript in an online repository. The journal encourages authors of original research manuscripts to upload their article to an institutional or public repository immediately after publication in the journal.

Long-term digital archiving

J-STAGE preserves its full digital library, including Geochemical Journal, with Portico in a dark archive (see In the event that the material becomes unavailable at J-STAGE, it will be released and made available by Portico.

Peer Review Process

Editorial and peer review process

The journal uses single-blind peer review. When a manuscript is submitted to the journal, the Executive Editor and the Vice Executive Editors perform initial screening. Manuscripts that do not fit the journal’s scope or preparation requirements, or are not deemed suitable for publication, are rejected without review. The remaining manuscripts are assigned to an Associate Editor, who assigns two reviewers to assess each manuscript. Reviewers are selected based on their expertise, reputation and previous experience as peer reviewers.

Upon receipt of the two reviewers’ reports, the Associate Editor makes the first decision on the manuscript. If the decision is to request revision of the manuscript, authors have 1 month (for minor revision decisions) or 3 months (for major revisions decisions) to resubmit a revised manuscript. Revised manuscripts submitted after this deadline may be treated as new submissions. The Associate Editor may send revised manuscripts to peer reviewers for their feedback or may use his or her own judgment to assess how closely the authors have followed the Associate Editor’s and the reviewers’ comments on the original manuscript.

The Associate Editor then makes a recommendation to the Executive Editor on the manuscript’s suitability for publication. The Executive Editor and Vice Executive Editors are responsible for making the final decision on each manuscript.

In cases where the Executive Editor is an author on a manuscript submitted to the journal, a Vice Executive Editor is responsible for making the final decision on the manuscript’s suitability for publication in the journal.

Reviewer selection, timing and suggestions

Reviewers are selected based on their expertise in the field, reputation, recommendation by others, and/or previous experience as peer reviewers for the journal and are asked to submit their first review within four weeks of accepting the invitation to review. Reviewers who anticipate any delays should inform the Editorial Office as soon as possible.

When submitting a manuscript to the journal, authors may provide, in the cover letter, five reviewers that they would like included in or excluded from the peer review process. Names, addresses, and e-mail addresses should be supplied. The Associate Editor may consider these suggestions but is under no obligation to follow them. The selection, invitation and assignment of peer reviewers is at the Associate Editor’s sole discretion.

Reviewer reports

It is the journal’s policy to transmit reviewers’ comments to the authors in their original form. However, the journal reserves the right to edit reviewers’ comments, without consulting the reviewers, if they contain offensive language, confidential information, or recommendations for publication.

Acceptance criteria

If a manuscript satisfies the journal’s requirements and represents a significant contribution to the published literature, the Associate Editor may recommend acceptance for publication in the journal.

Articles in Geochemical Journal must be:

  • novel and original
  • important additions to the field
  • within the subject area of the journal’s scope
  • descriptions of technically rigorous research
  • of high interest to the journal’s audience.

Simple geochemical description of specific samples without any broader implications are not prioritized for publication. If a manuscript does not meet the journal’s requirements for acceptance or revision, the Associate Editor may recommend rejection.

Editorial independence

The Geochemical Society of Japan (GSJ) has granted the journal’s Editorial Board complete and sole responsibility for all editorial decisions. The GSJ will not become involved in editorial decisions, except in cases of a fundamental breakdown of process.

Editorial decisions are based only on a manuscript’s scientific merit and are kept completely separate from the journal’s other interests. The authors’ ability to pay any publication charges has no bearing on whether a manuscript is accepted for publication in the journal.


Authors who believe that an editorial decision has been made in error may lodge an appeal with the Editorial Office. Appeals are only considered if the authors provide detailed evidence of a misunderstanding or mistake by a reviewer or editor. Appeals are considered carefully by the Executive Editor, whose decision is final. The guidelines of the Committee on Publication Ethics (COPE) are followed where and when relevant.

Confidentiality in peer review

The journal maintains the confidentiality of all unpublished manuscripts. Editors and reviewers will not:

  1. disclose a reviewer’s identity unless the reviewer makes a reasonable request for such disclosure
  2. discuss the manuscript or its contents with anyone not directly involved with the manuscript or its peer review
  3. use any data or information from the manuscript in their own work or publications
  4. use information obtained from the peer review process to provide an advantage to themselves or anyone else, or to disadvantage any individual or organization.

In addition, reviewers will not reveal their identity to any of the authors of the manuscript or involve anyone else in the review (for example, a post-doc or PhD student) without first requesting permission from the Associate Editor.

Conflicts of interest in peer review

A conflict of interest exists when there are actual, perceived or potential circumstances that could influence an editor’s ability to act impartially when assessing a manuscript. Such circumstances might include having a personal or professional relationship with an author, working on the same topic or in direct competition with an author, having a financial stake in the work or its publication, or having seen previous versions of the manuscript.

Members of the journal’s Editorial Board and reviewers undertake or are asked to declare any conflicts of interest when handling manuscripts. An editor or reviewer who declares a conflict of interest is unassigned from the manuscript in question and is replaced by a new editor or reviewer.

Editors try to avoid conflicts of interest when inviting reviewers, but it is not always possible to identify potential bias.

Errata and retractions

The journal recognizes the importance of maintaining the integrity of published literature.

A published article that contains an error may be corrected through the publication of an Erratum. Errata describe errors that significantly affect the scientific integrity of a publication, the reputation of the authors, or the journal itself. Authors who wish to correct a published article should contact the editor who handled their manuscript or the Editorial Office with full details of the error(s) and their requested changes. In cases where co-authors disagree over a correction, the Executive Editor may consult the Editorial Board or external peer reviewers for advice. If an Erratum is published, any dissenting authors will be noted in the text.

A published article that contains invalid or unreliable results or conclusions, has been published elsewhere, or has infringed codes of conduct (covering research or publication ethics) may be retracted. Individuals who believe that a published article should be retracted are encouraged to contact the journal’s Editorial Office with full details of their concerns. The Executive Editor will investigate further and contact the authors of the published article for their response. In cases where co-authors disagree over a retraction, the Executive Editor may consult the Editorial Board or external peer reviewers for advice. If a Retraction is published, any dissenting authors will be noted in the text.

The decision to publish Errata or Retractions is made at the sole discretion of the Executive Editor.

Editors as authors in the journal

Any member of the journal’s Editorial Board, including the Executive Editor, who is an author on a submitted manuscript is excluded from the peer review process. Within the journal’s online manuscript submission and tracking system, they will be able to see their manuscript as an author but not as an editor, thereby maintaining the confidentiality of peer review.

A manuscript authored by an editor of Geochemical Journal is subject to the same high standards of peer review and editorial decision making as any manuscript considered by the journal.

Responding to potential ethical breaches

The journal will respond to allegations of ethical breaches by following its own policies and, where possible, the guidelines of COPE.

Copyright, Open Access and Fees

Authors of accepted manuscripts will be invoiced for the APC before publication of their manuscript.

Waiver policy

Waivers are provided automatically when the corresponding author is from a Group A Research4Life country ( In cases of demonstrated financial hardship, the journal will consider a pre-submission application for a waiver from any corresponding author.

The ability of an author to pay the APC does not influence editorial decisions. To avoid any possibility of undue influence, editors involved with the decision-making process for articles are not involved in any deliberations on waivers.

Manuscript Submission

All manuscripts must be submitted via the journal’s online submission system, Editorial Manager: The original or revised manuscript text may be uploaded as a PDF or Microsoft (MS)-Word file, but a MS-Word file is required for the final manuscript text. Figures may be submitted separately in several other formats. Submit files containing the items requested above (the entire manuscript and a separate file containing the cover letter) in either PDF or MS-Word format. Acceptable formats for figures are TIFF, PICT, PostScript (PS and EPS), and PDF.

Manuscripts should be submitted only by the corresponding author, to avoid communication issues.

If you encounter any problems with online submission, please contact the Editorial Office at the details provided in the ‘Contact’ section. Manuscripts processed by the Editorial Office are assigned a manuscript number in the format GJXXXX (e.g., GJ1108). Please always use this number in all your correspondence with the editors.

Manuscript Preparation


The text should be concise and readily understandable. The manuscript must be typewritten, double-spaced, single-column, and with a margin of at least 2.5 cm on each side. Do not use fonts other than 12-point Times, Times New Roman, or Symbol. To assist reviewers, please add continuous line numbering.

English standard

Manuscripts should be written in clear, grammatically correct English (American or British usage is acceptable, but not a mixture of both). Authors who are not fluent in English are strongly encouraged to have their manuscript checked by a fluent English speaker or by an editing service prior to submission. If a manuscript is not clear due to poor English, it may be rejected without undergoing peer review.

Cover Letter

Authors should provide a Cover Letter briefly describing the subject, aims, and major findings of the submitted manuscript. The Cover Letter should also include the e-mail address of the corresponding author. Up to five suggested reviewers (names, addresses, and e-mails) may be provided during manuscript submission in Editorial Manager. Authors can also request to exclude some potential reviewers but clear explanations for the reasons must be provided in the Cover Letter.

Details of any relevant consent and/or ethics approvals, and other such items must be included in the cover letter. In addition, any other relevant information such as applications for APC waivers, other ethics declarations, and so forth should be included at the time of submission within the cover letter.


For all manuscript types, Figures and Tables (including the figure captions) should not be inserted in the text.

Article and Review manuscripts should be organized in the order: title, author's full name, affiliation, abstract (up to 250 words), five keywords, text, acknowledgments, references, tables, figure captions, figures.

Note manuscripts should be organized in the order: title, author's full name, affiliation, abstract (up to 150 words), five keywords, text, acknowledgments, references, tables, figure captions, figures. The manuscript should include a maximum of 10 references and 3 figures.

Express Letter manuscripts should be organized in the following order: title, author's full name, affiliation, abstract (up to 250 words), five keywords, text, acknowledgment, appendices, references, tables figure captions, figures. Manuscripts should include a maximum of 20 references and 3 figures or tables.

Data manuscripts should be organized in the following order: title, authors' full names, affiliations, abstract (up to 350 words), five keywords, text, acknowledgments, appendices, references, figure captions, tables, figures, and supplementary material.

Technical descriptions of methods should only be detailed when such methods are new.

Title and title page

The first page should contain the title, author list (with corresponding mark * on the corresponding author), permanent addresses of all authors, and the e-mail address and telephone number (if applicable) of the corresponding author. Please also add at most five keywords.

The title should describe the content of the article briefly but clearly and is important for search purposes by third-party services. Do not use the same main title with numbered minor titles, even for a series of papers by the same authors. Do not use abbreviations in the title, except those used generally in related fields.

Running Title (Short title)

The running title (short title) should not exceed 80 characters, including spaces.


Each abbreviation should be defined in parentheses together with its non-abbreviated term when it first appears in the text (except in the Title and Abstract).
