The GAC-MAC Joint Annual Meeting, the premier annual geoscience conference in Canada over the last six decades, is organized by the Geological Association of Canada (GAC®), in concert with the Mineralogical Association of Canada (MAC). The two associations have long enjoyed a close relationship, and have united the Canadian earth sciences community annually at GAC-MAC, a formal gathering of the best geological minds in the country, to celebrate our achievements, discuss new findings and develop further relationships.

In accordance with the general slogan of our annual joint meeting Exploring Geosciences Through Time and Space”, sessions are grouped according to four conference themes:

• Earth and Planetary Systems
• Life, Climate and Environment
• Tectonic Processes and Geohazards
• Resource Geoscience
