An established society may request affiliation with AAPG if its purposes and goals are compatible with AAPG's.
- Membership in the Society should consist of at least 60% degreed professional geologists.
- The Society should disseminate scientific information either through publications and/or meetings.
- Membership requirements in the Society should allow that an AAPG member anywhere in the world could qualify.
- The Society's main objective and practice should be geologic and the dissemination of geologic information, as opposed to a political organization with a scientific branch or division. Some flexibility should be used in applying this criteria, since in many parts of the world there may not be alternatives.
