Citing Your Sources: Understanding the Geological Society of America Citation Style

The Geological Society of America (GSA) citation style is a specific format used for citing sources in the geosciences. This style emphasizes clarity and consistency when referencing books, journal articles, maps, and other scholarly works. Following the GSA citation style ensures that your research is credible and gives proper credit to the original authors.

Why is the GSA Citation Style Important?

The GSA citation style isn’t just about following rules; it’s about upholding academic integrity and contributing to a global conversation in geoscience.

  • Avoiding Plagiarism: Accurately citing sources protects you from unintentional plagiarism.
  • Building Credibility: Using a recognized citation style like GSA instantly signals to your readers that your research is well-founded.
  • Facilitating Further Research: Proper citations create a clear path for others to follow your research trail and explore the sources that informed your work.

Key Elements of GSA Citation Style

The GSA style utilizes a combination of in-text citations and a comprehensive reference list at the end of your work.

In-Text Citations:

  • Format: (Author’s Last Name Year, Page Number)
    • Example: (Smith 2023, 45)
  • Multiple Authors: For works with two authors, use both last names. For three or more, use the first author’s last name followed by “et al.”
  • Direct Quotes: Always include page numbers for direct quotes.

Reference List:

  • Title: “References Cited” (centered at the top of a new page)
  • Order: Alphabetical order by the first author’s last name
  • Indentation: Use hanging indents (first line flush left, subsequent lines indented)

Common GSA Citation Examples:

Journal Article:
Smith, J.A., and Jones, B.D. 2023. The impact of climate change on coastal erosion. Journal of Geology, v. 125, no. 2, p. 15-28.

Book:
Johnson, C.C. 2022. Introduction to Plate Tectonics. 3rd ed. New York, New York: Academic Press. 456 p.

Chapter in an Edited Book:
Williams, L.M. 2021. Volcanic hazards and risk assessment. In: Brown, S.K., and Lee, J.H., eds., Volcanoes: A Global Perspective. London, England: Geological Society of London, p. 223-256.

Tips for Using GSA Citation Style:

  • Consult the GSA Manual: The official GSA style guide provides comprehensive rules and examples for various source types.
  • Use Citation Management Software: Tools like Zotero, Mendeley, or EndNote can streamline your citation process.
  • Proofread Carefully: Double-check all citations for accuracy and consistency.

Conclusion

Mastering the GSA citation style is essential for any geoscientist. By adhering to these guidelines, you demonstrate academic rigor and contribute to the open exchange of knowledge within the scientific community. Using GSA citations strengthens your work and ensures you are giving credit where credit is due.

FAQ

1. What do I do if I can’t find a publication date?
If no publication date is available, use “n.d.” (no date) in place of the year.

2. How do I cite a website in GSA style?
Website citations should include the author (if available), publication date (or last updated date), title of the webpage, website name, URL, and date accessed.

3. Is there a specific font or spacing requirement for GSA citations?
The GSA style guide does not specify a particular font or spacing requirement. However, it’s generally recommended to use a standard font (like Times New Roman or Arial) and double-space your reference list.
