Notes for Authors
It is the responsibility of authors to ensure that their manuscripts strictly adhere to the journal style. Manuscripts which do not conform to the journal style will not be accepted.
A guide to the style is presented here as follows:
- The manuscript must be double-spaced, on one side of standard A4 paper. It should leave 2.5 cm both top and bottom and 2.5 cm left and right. The author should use New Times Roman with 12 font size. Sub-titles should begin from the margin and be bolded.
- The author's name, immediately below the title on the first page, should be centred in Small Capitals; immediately beneath that, also centered, is the author's position and institutional affiliation in italic; beneath that, is the email address. Endnotes to the text should be kept to a minimum. Tables, figures and illustrations should be drawn precisely and boldly to permit photographic reproduction.
- A brief abstract of not more than 300 words, should appear at the head of the article describing the aim of the research work, methods main results and interpretations and conclusions of the article.
- The length of the manuscript should not exceed 8,000 words. Author(s) should submit manuscripts online via email to email@example.com or through the manuscript submission link available at JGST website tgs.or.tz/index.php/jtgs.
- The journal uses English (British or US but not the mix of the two). Authors are responsible for ensuring that their papers are readable and their academic content is fully understood by the editor and any reviewers. It is therefore advisable for authors to take their papers to professional language editors before submission.
- Line spacing: The main text is single-spaced with one-line space between paragraphs
- Title, headings and sub-headings should be bold: and should not be numbered. Use headline-style for titles, headings and sub-headings.
- The recommended style for bibliography and in-text citation is the American Psychological Association 7th Edition Format (APA) style.
- All manuscripts considered appropriate for the journal are subjected to at least two blind peer reviews before being accepted for publication. To preserve anonymity, manuscripts will be sent without authors' names and/or any reference that connects with the identity of the author in order to enhance objectivity in the reviewing process
- Submission of manuscripts to the Journal of the Geological Society of Tanzania indicates the author's willingness to publish in the journal.
- Copyright: When an article is published, the author vests control of all copyrights to the publisher. The author may, for instance, use parts of the article in elsewhere provided that he/she makes acknowledgement to the Journal of Geological Society of Tanzania.
- Begin on the left-hand side
- Capitalize all major words in the sub-headings with the rest of the letters in lowercase (e.g., Degradation of the Natural Resource Base)
- Sub-headings should not be numbered
- Sub-headings should not be in italic
- The first Sub-heading should be two lines below the Authors name.
- There is one-line space between the Sub-heading and the last line of the previous section
- The First paragraph under the Sub-heading comes directly under the Sub-heading without extra line spacing
- Tables must be submitted in editable text format.
- Tables should be placed next to the relevant text in the manuscript.
- Tables should be numbered consecutively reflecting their appearance in the manuscript text.
- Tables should not duplicate presented results.
- Table parts should be denoted by lowercase or uppercase letters (a or A, b or B, c or C, etc.). The authors must be consistent in their annotations
- A table caption explaining the components and the main message of each table must be supplied.
- Table captions should be placed directly above respective tables.
- The table caption must start with Table. in bold type, followed by table number also in bold type. Arabic numerals should be used in numbering the tables.
- Punctuation marks may or may not be included at the end of the table caption, but the author(s) should be consistent.
- Previously published elements of the presented table must be acknowledged accordingly.
- In case you include previously published tables, permission proof, to republish the same, from the copyright owners should be provided.
- Each figure must have a concise caption explaining its main message to the readers.
- The figure caption must capture all key elements for the intended reader whereby standard annotations (arrows, boxes, cycles, lines, numbers, letters, etc.) may be used accordingly.
- Figures should be placed next to the relevant text in the manuscript.
- Figures should be numbered consecutively reflecting their appearance in the manuscript text. Figure parts should be denoted by lowercase or uppercase letters (a or A, b or B, c or C, etc.). The authors must be consistent.
- Figure captions should be placed directly below respective figures.
- The figure caption must start with either Figure. or Fig. in bold type, followed by Figure/Fig number also in bold type. Arabic numerals should be used in numbering the Figures/Figs.
- Previously published elements of the presented figure must be acknowledged accordingly.
- In case you include previously published figures, permission proof, to republish the same, from the copyright owners should be provided.
- Submitted figures must have high quality. Poor quality figures may lead to direct manuscript rejection
- Statements and declarations
The following should be included under a separate Statement and declarations section just below the conclusion:
- Acknowledgement: The author should acknowledge funding sources, institutions and individuals with significant impact on their findings
- Competing interest statement: The authors should state any financial, institutional, ethical, political or personal relationships/interactions that could have affected their results
- Data availability statement: The authors must state if the used data will be available for other researchers to either reproduce their results or continue with further research in the area of interest
- Authors’ contribution statement: The contribution of each author must be made clear
- In-text citation
In-text citations are citations within the main body of text; which may be a direct quote or paraphrase. They correspond to a reference in the main reference list. These citations include the surname of the author(s) and date of publication only. Some examples are given below:
One or two authors
- Gama (2022) states that….
- Mineralization is associated with dolerite intrusions (Gama, 2022)
- Gama and Luhende (2017) state that...
- Gama & Luhende (2017) and Gama (2022) discuss…
- Gama & Luhende (2017), Saul (2019), Charles (2021) and Gama (2022) discuss…
- The basin stratigraphy is dissected by Jurassic and Cenozoic faults (Gama & Luhende, 2017)
- The Mngalu oil seep is structurally controlled (Gama & Luhende, 2017; Saul, 2019; Gama, 2022).
Three or more authors
- Gama et al. (2022) state that….
- Mineralization is associated with dolerite intrusions (Gama et al., 2022)
- Major faults have the overall NE-SW trend (Saul et al., 2019; Gama et al., 2022; Franke et al., 2023).
All references cited in the text should be listed in full at the end of the paper. The reference section should be 2-line spaces below the statements and declarations section of the article. Authors should make absolutely sure that all reference information is complete. References should be in the following standard form; the reference DOI, if available, should also be provided:
