Extended Abstract Submission Guidelines

  • We invite all authors of accepted Short Abstracts to submit an Extended Abstract if so desired. These will be available to all attendees in a digital format and published online for gratis public downloading.
  • For your reference and guidance, examples of extended abstracts from the previous five Conjugate Margins Conferences are accessible.
  • Please include your short abstract as submitted and/or accepted with any changes recommended by the committee.
  • Follow relevant parts of the short abstract guidelines regarding:
    • Subtle and/or overt sales pitches, including but not limited to:
      • Repeated use of product names, trade names or pictures, or repeated use of company logo
  • Use the guidance below and in the Halifax 2018 Extended Abstract format (22 kb .docx file) when formatting and writing your extended abstract, and in formatting your references.
  • Extended Abstracts
    • Are not manuscripts
    • Extended abstracts should total between 5 and 10 pages that INCLUDES text, figures, tables, references, etc. They can/should include:
      • Your short abstract
      • Appropriate text to expanding on your abstract
      • A limited number of figures
      • Applicable references
      • Any relevant maps, tables, etc.
    • If you have any questions, please contact one of the committee members
  • We are volunteers and appreciate not having to reformat or extensively edit your
    extended abstract. We believe that it is our job to make your extended abstract as grammatically correct and understandable as we can. However, if your do not follow and comply with our instructions, we will return the extended abstract to you for editing and revision

NOTE: Our guidelines are modified slightly from the AAPG’s “Instructions to Bulletin Authors” and the GCS SEPM’s “Author Instructions”

Extended Abstract Parameters

  • Use metric units of measure with the English unit equivalent in parentheses or, conversely, English units with metric equivalents in parentheses. Laboratory measurements do not require conversions.
  • Do not use abbreviations except for units of measure.
  • Limit the use of acronyms. Please define all acronyms and nonstandard abbreviations
    used within figures and tables in each figure caption and table footnote.
  • Cite figures in numerical order.
  • Cite all references and include complete information for each citation in References Cited
  • Limit the length of the abstract to no more than 250 words
  • Follow the North American Stratigraphic Code (see the AAPG Bulletin, v. 89, no. 11, p.
    1547–1591, or online).


The author must obtain permission to use previously published illustrations. Submit a letter of permission from the copyright holder with the manuscript before editing begins.

File Formats

The file formats below will give good results when converted to a PDF:

  • EPS (and EPSF, EPSI)
  • WMF (and EMF)
  • PDF — 300 dpi only — see PowerPoint 2007 instructions below
  • TIF/TIFF — 300 dpi only
  • JPG/JPEG (300 dpi only; TIFF preferred)

General Guidelines for all Illustrations

  1. Properly orient, crop, straighten, and digitally clean up scanned figures.
  2. Remove any in-house coding or internal reference numbers not relevant for this publication. Also, remove any figure number, caption, or author name that appears on the illustration itself; all figures will be identified only in the caption. The only labels that should appear are A, B, C labels (use capitals) for multipart figures or explanatory callouts.
  3. Size your digital graphics files. Larger graphics require excessive manipulation and cropping to fit into the layout. They also make the PDF files unnecessarily large.
  4. File names such as “org chart” or “first outcrop photo” are unacceptable as they cause confusion for us in the layout stage. Use the following convention when naming your graphic files: Fig01.***, Fig02.***, Fig03.***, etc.


Figures must include scales. Axes must be labeled on graphs.

Maps, Cross-Sections, and Seismic Lines

  • Only countries recognized by the United Nations may appear on maps.
  • Each map should contain a scale bar, north arrow, and a sufficient number (minimum of one set at or near each extremity) of coordinate (latitude, longitude) points to position, orient, and scale it, unless its sole purpose is to locate in general terms a larger scale map.
  • Each cross section and seismic line, as proprietary considerations allow, should be located on a map with the above basic information.
  • If known, projection and geodetic datum information should be included. Satellite imagery, orthophotos, and similar metric photography should also be treated as maps.
