　　chemical geology论文格式要求是怎样的呢?期刊格式要求对于投稿的作者很重要，为了保证初审顺利通过，论文格式要符合期刊要求，一般可以在期刊的官网上找到这些信息。

　　我们花时间整理了一份论文格式，作者无需再盲目去找，以下是这本期刊的投稿要求信息：

　　Writing and Formatting

　　File format

　　We ask you to provide editable source files for your entire submission (including figures, tables and text graphics). Some guidelines:

　　Save files in an editable format, using the extension .doc/.docx for Word files and .tex for LaTeX files. A PDF is not an acceptable source file.

　　Lay out text in a single-column format.

　　Use spell-check and grammar-check functions to avoid errors.

　　We advise you to read our Step-by-step guide to publishing with Elsevier.

　　LaTeX

　　We encourage you use our LaTeX template when preparing a LaTeX submission. You will be asked to provide all relevant editable source files upon submission or revision.

　　Support for your LaTeX submission:

　　LaTeX submission instructions and templates

　　Journal Article Publishing Support Center LaTeX FAQs and support

　　Researcher Academy’s Beginners’ guide to writing a manuscript in LaTeX

　　Title page

　　You are required to include the following details in the title page information:

　　Article title. Article titles should be concise and informative. Please avoid abbreviations and formulae, where possible, unless they are established and widely understood, e.g., DNA).

　　Author names. Provide the given name(s) and family name(s) of each author. The order of authors should match the order in the submission system. Carefully check that all names are accurately spelled. If needed, you can add your name between parentheses in your own script after the English transliteration.

　　Affiliations. Add affiliation addresses, referring to where the work was carried out, below the author names. Indicate affiliations using a lower-case superscript letter immediately after the author's name and in front of the corresponding address. Ensure that you provide the full postal address of each affiliation, including the country name and, if available, the email address of each author.

　　Corresponding author. Clearly indicate who will handle correspondence for your article at all stages of the refereeing and publication process and also post-publication. This responsibility includes answering any future queries about your results, data, methodology and materials. It is important that the email address and contact details of your corresponding author are kept up to date during the submission and publication process.

　　Present/permanent address. If an author has moved since the work described in your article was carried out, or the author was visiting during that time, a "present address" (or "permanent address") can be indicated by a footnote to the author's name. The address where the author carried out the work must be retained as their main affiliation address. Use superscript Arabic numerals for such footnotes.

　　Abstract

　　You are required to provide a concise and factual abstract. The abstract should briefly state the purpose of your research, principal results and major conclusions. Some guidelines:

　　Abstracts must be able to stand alone as abstracts are often presented separately from the article.

　　Avoid references. If any are essential to include, ensure that you cite the author(s) and year(s).

　　Avoid non-standard or uncommon abbreviations. If any are essential to include, ensure they are defined within your abstract at first mention.

　　Keywords

　　You are required to provide 1 to 7 keywords for indexing purposes. Keywords should be written in English. Please try to avoid keywords consisting of multiple words (using "and" or "of").

　　We recommend that you only use abbreviations in keywords if they are firmly established in the field.

　　Highlights

　　You are required to provide article highlights at submission.

　　Highlights are a short collection of bullet points that should capture the novel results of your research as well as any new methods used during your study. Highlights will help increase the discoverability of your article via search engines. Some guidelines:

　　Submit highlights as a separate editable file in the online submission system with the word "highlights" included in the file name.

　　Highlights should consist of 3 to 5 bullet points, each a maximum of 85 characters, including spaces.

　　We encourage you to view example article highlights and read about the benefits of their inclusion.

　　Graphical abstract

　　You are encouraged to provide a graphical abstract at submission.

　　The graphical abstract should summarize the contents of your article in a concise, pictorial form which is designed to capture the attention of a wide readership. A graphical abstract will help draw more attention to your online article and support readers in digesting your research. Some guidelines:

　　Submit your graphical abstract as a separate file in the online submission system.

　　Ensure the image is a minimum of 531 x 1328 pixels (h x w) or proportionally more and is readable at a size of 5 x 13 cm using a regular screen resolution of 96 dpi.

　　Our preferred file types for graphical abstracts are TIFF, EPS, PDF or MS Office files.

　　We encourage you to view example graphical abstracts and read about the benefits of including them.

　　Units

　　This journal requires you to use the international system of units (SI) which follows internationally accepted rules and conventions. If other units are mentioned within your article, you should provide the equivalent unit in SI.

　　Math formulae

　　Submit math equations as editable text, not as images.

　　Present simple formulae in line with normal text, where possible.

　　Use the solidus (/) instead of a horizontal line for small fractional terms such as X/Y.

　　Present variables in italics.

　　Denote powers of e by exp.

　　Display equations separately from your text, numbering them consecutively in the order they are referred to within your text.

　　Tables

　　Tables must be submitted as editable text, not as images. Some guidelines:

　　Place tables next to the relevant text or on a separate page(s) at the end of your article.

　　Cite all tables in the manuscript text.

　　Number tables consecutively according to their appearance in the text.

　　Please provide captions along with the tables.

　　Place any table notes below the table body.

　　Avoid vertical rules and shading within table cells.

　　We recommend that you use tables sparingly, ensuring that any data presented in tables is not duplicating results described elsewhere in the article.

　　Figures, images and artwork

　　Figures, images, artwork, diagrams and other graphical media must be supplied as separate files along with the manuscript. We recommend that you read our detailed artwork and media instructions. Some excerpts:

　　When submitting artwork:

　　Cite all images in the manuscript text.

　　Number images according to the sequence they appear within your article.

　　Submit each image as a separate file using a logical naming convention for your files (for example, Figure_1, Figure_2 etc).

　　Please provide captions along with the artwork.

　　Text graphics may be embedded in the text at the appropriate position. If you are working with LaTeX, text graphics may also be embedded in the file.

　　Artwork formats

　　When your artwork is finalized, "save as" or convert your electronic artwork to the formats listed below taking into account the given resolution requirements for line drawings, halftones, and line/halftone combinations:

　　Vector drawings: Save as EPS or PDF files embedding the font or saving the text as "graphics."

　　Color or grayscale photographs (halftones): Save as TIFF, JPG or PNG files using a minimum of 300 dpi (for single column: min. 1063 pixels, full page width: 2244 pixels).

　　Bitmapped line drawings: Save as TIFF, JPG or PNG files using a minimum of 1000 dpi (for single column: min. 3543 pixels, full page width: 7480 pixels).

　　Combinations bitmapped line/halftones (color or grayscale): Save as TIFF, JPG or PNG files using a minimum of 500 dpi (for single column: min. 1772 pixels, full page width: 3740 pixels).

　　Please do not submit:

　　files that are too low in resolution (for example, files optimized for screen use such as GIF, BMP, PICT or WPG files).

　　disproportionally large images compared to font size, as text may become unreadable.

　　Figure captions

　　All images must have a caption. A caption should consist of a brief title (not displayed on the figure itself) and a description of the image. We advise you to keep the amount of text in any image to a minimum, though any symbols and abbreviations used should be explained.

　　Provide captions in a separate file.

　　Color artwork

　　If you submit usable color figures with your accepted article, we will ensure that they appear in color online.

　　Please ensure that color images are accessible to all, including those with impaired color vision. Learn more about color and web accessibility.

　　For articles appearing in print, you will be sent information on costs to reproduce color in the printed version, after your accepted article has been sent to production. At this stage, please indicate if your preference is to have color only in the online version of your article or also in the printed version.

　　Generative AI and Figures, images and artwork

　　Please read our policy on the use of generative AI and AI-assisted tools in figures, images and artwork, which states:

　　We do not permit the use of Generative AI or AI-assisted tools to create or alter images in submitted manuscripts.

　　The only exception is if the use of AI or AI-assisted tools is part of the research design or methods (for example, in the field of biomedical imaging). If this is the case, such use must be described in a reproducible manner in the methods section, including the name of the model or tool, version and extension numbers, and manufacturer.

　　The use of generative AI or AI-assisted tools in the production of artwork such as for graphical abstracts is not permitted. The use of generative AI in the production of cover art may in some cases be allowed, if the author obtains prior permission from the journal editor and publisher, can demonstrate that all necessary rights have been cleared for the use of the relevant material, and ensures that there is correct content attribution.

　　Supplementary material

　　We encourage the use of supplementary materials such as applications, images and sound clips to enhance research. Some guidelines:

　　Cite all supplementary files in the manuscript text.

　　Submit supplementary materials at the same time as your article. Be aware that all supplementary materials provided will appear online in the exact same file type as received. These files will not be formatted or typeset by the production team.

　　Include a concise, descriptive caption for each supplementary file describing its content.

　　Provide updated files if at any stage of the publication process you wish to make changes to submitted supplementary materials.

　　Do not make annotations or corrections to a previous version of a supplementary file.

　　Switch off the option to track changes in Microsoft Office files. If tracked changes are left on, they will appear in your published version.

　　We recommend you upload research data to a suitable specialist or generalist repository. Please read our guidelines on sharing research data for more information on depositing, sharing and using research data and other relevant research materials.

　　Video

　　This journal accepts video material and animation sequences to support and enhance your scientific research. We encourage you to include links to video or animation files within articles. Some guidelines:

　　When including video or animation file links within your article, refer to the video or animation content by adding a note in your text where the file should be placed.

　　Clearly label files ensuring the given file name is directly related to the file content.

　　Provide files in one of our recommended file formats. Files should be within our preferred maximum file size of 150 MB per file, 1 GB in total.

　　Provide "stills" for each of your files. These will be used as standard icons to personalize the link to your video data. You can choose any frame from your video or animation or make a separate image.

　　Provide text (for both the electronic and the print version) to be placed in the portions of your article that refer to the video content. This is essential text, as video and animation files cannot be embedded in the print version of the journal.

　　We publish all video and animation files supplied in the electronic version of your article.

　　For more detailed instructions, we recommend that you read our guidelines on submitting video content to be included in the body of an article.

　　Research data

　　We are committed to supporting the storage of, access to and discovery of research data, and our research data policy sets out the principles guiding how we work with the research community to support a more efficient and transparent research process.

　　Research data refers to the results of observations or experimentation that validate research findings, which may also include software, code, models, algorithms, protocols, methods and other useful materials related to the project.

　　Please read our guidelines on sharing research data for more information on depositing, sharing and using research data and other relevant research materials.

　　For this journal, the following instructions from our research data guidelines apply.

　　Option C: Research data deposit, citation and linking

　　Learn more about linking research data and research articles in ScienceDirect.

　　Research Elements

　　This journal enables the publication of research objects (e.g. data, methods, protocols, software and hardware) related to original research in Elsevier's Research Elements journals.

　　Research Elements are peer-reviewed, open access journals which make research objects findable, accessible and reusable. By providing detailed descriptions of objects and their application with links to the original research article, your research objects can be placed into context within your article.

　　You will be alerted during submission to the opportunity to submit a manuscript to one of the Research Elements journals. Your Research Elements article can be prepared by you, or by one of your collaborators.

　　Article structure

　　Article sections

　　Divide your article into clearly defined and numbered sections. Number subsections 1.1 (then 1.1.1, 1.1.2, ...), then 1.2, etc.

　　Use the numbering format when cross-referencing within your article. Do not just refer to "the text."

　　You may give subsections a brief heading. Headings should appear on a separate line.

　　Do not include the article abstract within section numbering.

　　Introduction

　　The introduction should clearly state the objectives of your work. We recommend that you provide an adequate background to your work but avoid writing a detailed literature overview or summary of your results.

　　Material and methods

　　The materials and methods section should provide sufficient details about your materials and methods to allow your work to be reproduced by an independent researcher. Some guidelines:

　　If the method you used has already been published, provide a summary and reference the originally published method.

　　If you are quoting directly from a previously published method, use quotation marks and cite the source.

　　Describe any modifications that you have made to existing methods.

　　Theory and calculation

　　The theory section should lay the foundation for further work by extending the background you provided in the introduction to your article. The calculation section should represent a practical development from a theoretical basis.

　　Results

　　Results should be clear and concise. We advise you to read the sections in this guide on supplying tables, artwork, supplementary material and sharing research data.

We recommend that you avoid the use of extensive citations and discussion of published literature in the discussion section.

　　Conclusion

　　The conclusion section should present the main conclusions of your study. You may have a stand-alone conclusions section or include your conclusions in a subsection of your discussion or results and discussion section.

　　Glossary

　　Please provide definitions of field-specific terms used in your article, in a separate list.

　　Abbreviations

　　Abbreviations which are not standard in the field should be defined in a footnote on the first page of your article.

　　Abbreviations which are essential to include in your abstract should be defined at first mention in your abstract, as well as in a footnote on the first page of your article.

　　Before submission we recommend that you review your use of abbreviations throughout your article to ensure that it is consistent.

　　Acknowledgements

　　Include any individuals who provided you with help during your research, such as help with language, writing or proof reading, in the acknowledgements section. Acknowledgements should be placed in a separate section which appears directly before the reference list. Do not include acknowledgements on your title page, as a footnote to your title, or anywhere else in your article other than in the separate acknowledgements section.

　　Author contributions: CRediT

　　Not all CRediT roles will apply to every manuscript and some authors may contribute through multiple roles.

　　We advise you to read more about CRediT and view an example of a CRediT author statement.

　　Funding sources

　　Authors must disclose any funding sources who provided financial support for the conduct of the research and/or preparation of the article. The role of sponsors, if any, should be declared in relation to the study design, collection, analysis and interpretation of data, writing of the report and decision to submit the article for publication. If funding sources had no such involvement this should be stated in your submission.

　　List funding sources in this standard way to facilitate compliance to funder's requirements:

　　Funding: This work was supported by the National Institutes of Health [grant numbers xxxx, yyyy]; the Bill & Melinda Gates Foundation, Seattle, WA [grant number zzzz]; and the United States Institutes of Peace [grant number aaaa].

　　It is not necessary to include detailed descriptions on the program or type of grants, scholarships and awards. When funding is from a block grant or other resources available to a university, college, or other research institution, submit the name of the institute or organization that provided the funding.

　　If no funding has been provided for the research, it is recommended to include the following sentence:

　　This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.

　　Appendices

　　We ask you to use the following format for appendices:

　　Identify individual appendices within your article using the format: A, B, etc.

　　Give separate numbering to formulae and equations within appendices using formats such as Eq. (A.1), Eq. (A.2), etc. and in subsequent appendices, Eq. (B.1), Eq. (B. 2) etc. In a similar way, give separate numbering to tables and figures using formats such as Table A.1; Fig. A.1, etc.

　　References

　　References within text

　　Any references cited within your article should also be present in your reference list and vice versa. Some guidelines:

　　References cited in your abstract must be given in full.

　　We recommend that you do not include unpublished results and personal communications in your reference list, though you may mention them in the text of your article.

　　Any unpublished results and personal communications included in your reference list must follow the standard reference style of the journal. In substitution of the publication date add "unpublished results" or "personal communication."

　　References cited as "in press" imply that the item has been accepted for publication.

　　Linking to cited sources will increase the discoverability of your research.

　　Before submission, check that all data provided in your reference list are correct, including any references which have been copied. Providing correct reference data allows us to link to abstracting and indexing services such as Scopus, Crossref and PubMed. Any incorrect surnames, journal or book titles, publication years or pagination within your references may prevent link creation.

　　We encourage the use of Digital Object Identifiers (DOIs) as reference links as they provide a permanent link to the electronic article referenced. See the example below, though be aware that the format of such citations should be adapted to follow the style of other references in your paper.

　　DOI link example (for an article not yet in an issue):

　　VanDecar J.C., Russo R.M., James D.E., Ambeh W.B., Franke M. (2003). Aseismic continuation of the Lesser Antilles slab beneath northeastern Venezuela. Journal of Geophysical Research, https://doi.org/10.1029/2001JB000884.

　　Reference format

　　This journal does not set strict requirements on reference formatting at submission. Some guidelines:

　　References can be in any style or format as long as the style is consistent.

　　Author names, journal or book titles, chapter or article titles, year of publication, volume numbers, article numbers or pagination must be included, where applicable.

　　Use of DOIs is recommended.

　　Our journal reference style will be applied to your article after acceptance, at proof stage. If required, at this stage we will ask you to correct or supply any missing reference data.

　　Reference style

　　All citations in the text should refer to:

　　Single author: the author's name (without initials, unless there is ambiguity) and the year of publication.

　　Two authors: both authors' names and the year of publication.

　　Three or more authors: first author's name followed by 'et al.' and the year of publication.

　　Citations can be made directly (or parenthetically). Groups of references can be listed either first alphabetically, then chronologically, or vice versa. Examples: "as demonstrated (Allan, 2020a, 2020b; Allan and Jones, 2019)" or "as demonstrated (Jones, 2019; Allan, 2020). Kramer et al. (2023) have recently shown".

　　The list of references should be arranged alphabetically and then chronologically if necessary. More than one reference from the same author(s) in the same year must be identified by the letters 'a', 'b', 'c', etc., placed after the year of publication.

　　year

　　global persistent identifier

　　Add [dataset] immediately before your reference. This will help us to properly identify the dataset. The [dataset] identifier will not appear in your published article.

　　Preprint references

　　We ask you to mark preprints clearly. You should include the word "preprint" or the name of the preprint server as part of your reference and provide the preprint DOI.

　　Where a preprint has subsequently become available as a peer-reviewed publication, use the formal publication as your reference.

　　If there are preprints that are central to your work or that cover crucial developments in the topic, but they are not yet formally published, you may reference the preprint.

　　Reference management software

　　Most Elsevier journals have their reference template available in popular reference management software products. These include products that support Citation Style Language (CSL) such as Mendeley Reference Manager.

　　If you use a citation plug-in from these products, select the relevant journal template and all your citations and bibliographies will automatically be formatted in the journal style. We advise you to remove all field codes before submitting your manuscript to any reference management software product.
