Abstract Guidelines

  • Abstracts typically summarize new research results and conclusions, or offer synthesis and discussion that represent the meeting contribution.
  • Abstracts should not introduce new formal rock or meteorite names, new stratigraphic or time units, nor new fossil names. New mineral names will be introduced only with prior approval by the International Mineralogical Association.
  • Abstract text must not exceed 3000 characters (spaces included), excluding title, authors, and addresses.
  • New this year, a single graphical abstract file (JPG, PNG, PDF) can also be uploaded to accompany your abstract submission. The graphical abstract can take the form of a key summary figure or a photograph with a caption, and will be included in the abstract volume with your abstract.
  • The deadline for abstract submission through the submission portal is July 12, 2021. Late submissions will not be accepted.
  • You can make changes to your abstract by re-entering the submission site at any time up to the submission deadline.

A non-refundable $50 (CAN) abstract submission fee is payable to submit each abstract. More than one abstract fee ticket can be purchased in the same transaction, if desired.

–> Review and acceptance of abstracts will be assessed primarily by session conveners and by the GAC-MAC 2021 Scientific Program Committee, based upon scientific merit of the contribution and compliance with required format. Presenting authors will receive a confirmation of receipt following abstract submission and will be informed as to whether it has been accepted in August, 2021.

–> For your abstract submission, please have your choice of session decided and all author information, abstract text and (if desired) graphical abstract ready to provide on the submission site.

–> Please note that use of an updated version of popular web browsers (Firefox, Chrome, Explorer) is recommended for the abstract submission site.

3. Submit abstract content after the payment has been made. Further edits up to the submission deadline can be made as well.
