Bulletin of Geology and Mining (Boletín Geológico y Minero) publishes original research articles related to the Earth Sciences, in English (preferably) or in Spanish.

TEXT: it is recommended the use of the text template that can be downloaded here (link). Otherwise, the manuscript must be submitted using a standardized word processor file (.doc, .docx or .rtf type files), strictly following the rules indicated below. Concision is required, and the manuscript extent will depend on the amount of data and depth of the discussions necessary for the content of the article to be understandable. The manuscript must include line numbering, from beginning to end, and each paragraph must have a first-line indent to the right. The font size will be 12 pt (Times New Roman font or similar) and double line spacing.

The title of the article will be brief and informative about its contents. The originals in English must also contain the title in Spanish and vice versa (the editorial Board can assist with translations into Spanish). Additionally, manuscript submissions must include a very brief (running) title, with a maximum of 60 characters (blank spaces included).

Authors will appear in lowercase (initial capital) in the order in which they wish to be cited. First the full name, followed by the surname or surnames, and each author must be separated from the next by a comma. Affiliations will be indicated, with the complete postal address of their affiliation and email. The use of an identifier (for example, a number) is recommended to associate each author with their corresponding affiliation. During submission, it will be indicated the name, surname(s) and email of the corresponding author, with whom the journal will maintain contact throughout the review/publication process. All authors must include their ORCID identifier (

An abstract will be included in English and in Spanish (the editorial Board can assist with translations into Spanish), with a minimum length of 100 words and a maximum of 250 words, in each language. The abstract must be concise and indicative of the content and contributions of the article as a whole.

Next, up to five keywords in both English and Spanish must be included (the editorial Board can assist with translations into Spanish). Of these five keywords, it is suggested that at least three be included in the IGME keywords thesaurus PDF, available on the Bulletin website ( Each keyword must start with a capital letter, and will be separated from the rest by a semicolon (;).

Each article must include, after the Keywords, three key points that synthesize the essence of the work presented. Key Points may not exceed 140 characters, including blank spaces, must be written in both English and Spanish (the editorial Board can assist with translations into Spanish), and each on a different line of text.

The different sections of the text will be titled in lowercase and bold, with numbers separated from the title by a point (for example, "1. Section"). Up to two levels of subsections are allowed, which must be titled in lowercase and with the appropriate numbering (for example, "1.2. Subsection" or "1.2.1. Subsection"). It is recommended to include the Introduction and Conclusions sections; If the structure and contents allow it, it is also recommended to use the classic structure of Objectives, Study area, Methodology, Results and Discussion. The last section will be the References section, preceded, if appropriate, by the Acknowledgments. The objectives and relevance of the work must be clearly expressed, and the data will be presented separately from the interpretations.

Footnotes or end-of-text notes are not allowed, so any comments should be included in the main body of the manuscript.

If the article includes figures, the figure captions should be included at the end of the manuscript, after the list of references. Each figure must include a caption in English and another in Spanish (the editorial Board can assist with translations into Spanish). The figure caption will begin with “Figure 1. Xxxx”, written in English and Spanish, on consecutive and different lines for each language. In the case of tables, the same rules will apply.

In the bibliographic references included in the main body of the text, the full surnames used by the authors in the corresponding work will be entered, in lower case, citing it in the final bibliography in the same way as in the text. In the case of three or more authors, “et al.” will be used. For citations of a work by two authors, their last names will be related to the conjunction "and", regardless of whether the main text is in English or Spanish.

The references of all the works cited will be included in the final section of REFERENCES. For its correct visualization, each reference must be included in an independent paragraph, which will have a hanging indent in the first line (the first line begins more to the left than the following ones). References will follow a strict format. Authors must follow APA style, which uses the Harvard author-date system for in-text citations. Names of the journals, books, publishing houses, etc. must be written in full. We recommend using DOIs. As an example, for the different types of documents:

    References to measurement units and their abbreviations will be made following the International System of Units (SI) adopted by the General Conference of Weights and Measures and in force in the European Union. As an example, the abbreviations and symbols of the units of measure will not have a period at the end, nor can they be in the plural.

    NUMBERS: Scientific notation is adopted, without thousands separator (half a space will be included in printing) and with the point as decimal separator.

    TABLES: The tables and charts that contain text or numerical data organized in rows and columns, will all appear cited as tables (for example, "Table 1"), and will be formatted to fit into one or two columns (80 or 170 mm), and the proportional height; the maximum will be the box dimensions of one full page. The text or numbers they contain, if applicable, must be read clearly at the chosen size, the size of the characters never being less than 8 pt. The format of the table should avoid, whenever possible, the use of a grid with vertical and horizontal lines to separate rows and columns. The use of only a few horizontal lines is recommended. Each of the tables will be incorporated as a separate file from the main text file. The tables will preferably be sent in image format, after being exported from the software in which they were generated, following the requirements of the figures.

    FIGURES: The original illustrations (drawings, maps, diagrams, sketches, photographs, etc.), will be cited in the text and numbered consecutively all as figures, and will be prepared to fit into one or two columns (80 or 170 mm), and the proportional height; the maximum will be the dimensions of the box of a full page, admitting, if necessary, figures that occupy a larger extent (for example, maps, correlation tables, cores, etc.). The text or numbering they contain, if applicable, must be read correctly at the chosen size.

    The figures will always be sent separately from the text, each one as an independent image file and with a minimum resolution of 300 dpi for the final edition size. Files with JPEG, TIFF, EPS, PDF, PNG or similar formats will be accepted. Each file must be named following a clear nomenclature that allows its correct identification (for example Fig1.JPEG, Tab1.TIFF).

    The illustrations must be original and property of the authors and, if affected by copyright restrictions, it is the responsibility of the authors to process the authorization for publication in the Bulletin. In any circumstance, the sources from which said illustrations were extracted, modified or adapted must be expressly cited.


    Manuscripts must be submitted in digital format (computer files indicated) by email (, provided that the size of the attached files does not exceed 10 Mb per message.

    In case the size of the files is greater than 10 Mb, the set of files can be sent in a sequence of messages until all the files are submitted, expressly indicating in each individual message that it is part of a single submission. In addition, it is advisable to contact the journal ( to find a suitable submission method, for example, in the case of large figures or tables.

    The corresponding author will have acknowledgment of receipt, by email notification, of each of the steps of the editorial process, from the correct reception of the material submitted, to the final decision regarding it.
