authorathttps://www.editorialmanager.com/gj/. The Geochemical Journal editorial office may be reached at
gj@geochem.jp.
Papers submitted will be judged from the standpoint of scientific originality and novelty. An Associate
Editor specializing in the subject area will arrange for a review of paper and will communicate directly withthe authors; (Some papers are handled by the Executive Editor or the Vice Executive Editor.) The Executive
Editor and the Vice Executive Editor, however, reserve the final decision on publication.
Papers must not have been previously published. Authors must agree not to submit elsewhere a paper
submitted to and accepted by Geochemical Journal. Geochemical Journal publishes papers in six categories:
invited reviews, articles, notes, express letters, data and critical comments. "Invited Reviews" are solicited by
the Editor, and provide a synthesis of a major area of interest. "Articles" are the principal mode of reporting
research. "Notes" are short reports intended mainly for data presentation to benefit the geochemistrycommunity. "Express Letters" are short, timely papers which report a new idea, experimental method,
discovery, invention or so on. "Express Letters" should not exceed six printed pages, including all tables,
figures and references. "Data" are analytical reports of valuable geochemical data and datasets (database),
which are of international interest to the geochemical research and contribute to the development of the field.
The category does not call for a new scientific discovery but provides scientifically meaningful and reliabledatasets. "Critical Comments" may also be submitted on a paper previously published in Geochemical
Journal. The author of the original paper will be given the opportunity to prepare a reply.

EXTENDED INSTRUCTIONS TO AUTHORS
Detailed instructions for submission to Geochemical Journal — July 2009
Scope and overview
Geochemical Journal is an international peer-reviewed journal devoted to original research papers ingeochemistry and cosmochemistry. It is the primary journal of the Geochemical Society of Japan. Areas ofresearch are as follows:
Cosmochemistry,
Mineral and Rock Chemistry,
Volcanology and Hydrothermal Chemistry,
Isotope Geochemistry and Geochronology,
Atmospheric Chemistry,
Hydro- and Marine Chemistry,
Organic Geochemistry,
Environmental Geochemistry
Papers submitted will be judged from the standpoint of scientific originality and novelty. Papers are
expected to provide unique and important new ideas or information on geochemical and cosmochemical
problems and to give implication of broad rather than local significance to the geochemical community.
Submission Procedure
Submission to Geochemical Journal is taken to mean that all the listed authors have agreed all the content.
The corresponding author is responsible for having ensured that this agreement has been reached.
Manuscripts
shouldbesubmitted
onlinebythecorresponding
authorathttps://www.editorialmanager.com/gj/. The Geochemical Journal editorial office may be reached at
gj@geochem.jp. The manuscripts processed by the Editorial Office receive a consecutive number in theformat GJ1XXX (ex. GJ1108). Please use always this number in all your correspondence with the Editors.
Evaluation Procedure
An Associate Editor specializing in the subject area will arrange for a review and will communicate directlywith the authors (some papers are handled by the Executive Editor or the Vice Executive Editor). The
Executive Editor and the Vice Executive Editor, however, reserve the final decision on publication. If apaper is considered to be very important, the Executive Editor, the Vice Executive Editor and the Associate
Editors will assist rapid publication by reviewing the paper. If the Associate Editor asks to revise the text, therevised version should be submitted within a certain time limit:
Minor revision - 1 month
Major revision - 3 months
After this period, the article will be regarded as a new submission.
Papers must not have been previously published. Authors must agree not to submit elsewhere a paper
submitted to and accepted by Geochemical Journal. If some part of the paper have been submitted or
published elsewhere, the authors are required to disclose it and to explain the reason for including thosesections.
Proofs will be supplied to the author for final correction before publication. A reprint order form will be sentwith the proofs.
Categories of published papers
Geochemical Journal publishes papers in five categories: Invited Reviews, Articles, Notes, Express Letters,
Data, and Critical Comments.
Invited Reviews
The Editor exclusively solicits these papers. Unsolicited Reviews will be automatically discarded. Invited
Reviews provide summaries of scientific progress in selected frontier fields and provide newinterpretation. The aim of Invited Reviews is to enhance the understanding and to promote the interaction
among major areas of the geochemical community.
ArticlesThey are the principal mode of reporting research. They present important new results and deal withmajor studies that address a significant area of interest to the readers. They should be as concise as
possible. Text cannot exceed 6500 words excluding abstract, acknowledgements, references and figure
captions, not more than 80 references, and not more than a total of 10 figures plus tables. Large tables
should be submitted as part of Supplementary Material. Abstract should not exceed 350 words. Papers
exceeding the size requirements could be send back to authors for changes, before evaluation procedure
starts.
Notes
These are short reports intended mainly for data presentation to benefit the geochemistry community.
Short papers dealing with new idea and/or new experimental method are also accepted as Notes. Text
should not exceed 1500 words. Abstract should be of 150 words. The paper should include not more than
10 references and 3 figures. Tables, if any will be printed as Supplementary Material.
Express Letters
These are short, timely papers which report a new idea, experimental method, discovery, invention. They
should not exceed 6 printed pages, including all tables, figures and references. The editors will assist
rapid publication of Express Letters, and papers of this category will normally be published within twomonths after submission. Text should be not more than 6 printed pages including abstract (250 words),
acknowledgements, references and figure captions. A maximum of 20 references and 2-3 figures are
accepted plus tables.
Data
These are analytical reports of valuable geochemical data and datasets (database), which are ofinternational interest to the geochemical research and contribute to the development field. The category
does not call for a new scientific discovery but provides scientifically meaningful and reliable datasets.
Critical Comments
They may also be submitted on a paper previously published in Geochemical Journal. The author of theoriginal paper will be given the opportunity to prepare a reply. Critical comments and replies arereviewed and edited as Articles.
Special Issues
Groups of papers on a particular topic will be published together by previous arrangement with the
Executive Editor in a Special issue of Geochemical Journal.
Manuscript Format and Text Requirements
The Executive Editor and Vice-Executive Editor will assume the responsibility to reject automaticallymanuscripts that are not properly organized, following the basic requirements here below illustrated.
1. Papers must be written in good English (American or British usage is accepted, but not a mixture ofboth). The text should be concise and readily understandable.

DETAILED INFORMATION FOR CONTRIBUTORS TO "DATA" CATEGORY
GeneralThe "data" category includes the following three types of manuscripts; scientific report, database, andcompilation dataset. The category calls for analytical repots of valuable geochemical data and datasets(databases) that are of international interest to geochemical research and contribute to its development. For
example, scientific reports of chemical compositions and isotope ratios of internationally available
geochemical reference materials and extraterrestrial materials. The category does not call for a new scientificdiscovery, but provides scientifically meaningful and reliable datasets. The submitted manuscript isreviewed in terms of the value of the data and its utility. In particular, the validity and rigidity ofexperimental and observational procedures, data generation processes, and statistical processes are reviewed
by specialists.
Manuscript Preparation
Manuscripts should be written in English. Each manuscript should be organized in the following order: title,
authors' full names, affiliations, abstract, keywords, text, acknowledgments, appendix, references, figure
captions, tables, figures, and supplementary material. The SI units should be used according to theInternational Union of Pure and Applied Chemistry (IUPAC) guidelines.
Abstract should not exceed 350 words and should be followed by five keywords. The introduction must
provide a background of the data, database and potential benefits. Methods should include detailed
analytical procedures, experimental design, and computational calculation, that are easily reproducible.
Technical validation and statistical processing of data or alternative criteria of data must be described tosupport quality control, such as statistical analyses of experimental error and variation. The Results andDiscussion should include chemical compositions and isotope ratios of internationally available geochemicalreference materials or alternative reference materials to evaluate the accuracy of the data. It is highly
recommended that some applications of datasets are discussed. 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 the Supplementary Material.
Formats of the manuscript, figures, and tables
Acceptable manuscript formats are PDF and MS Word. The acceptable formats of the figures are TIFF, PICT,PostScript (PS and EPS), and PDF. The acceptable formats of tables are PDF and MS Word. Large tables ofsupplementary material in PDF, MS Word, MS Excel, MS Access, XML format, and csv format can be
accepted.
