In the following pages, we are pleased to publish the abstracts of oral and poster presentations from the meeting, which included the following Special Sessions: (1) Mapping, Petrology, Geochemistry, and Mineral Deposits: In Memory of Dr. Trevor MacHattie (1974–2018); (2) Paleontology and Sedimentology in Atlantic Canada: In Memory of Dr. Ron Pickerill (1947– 2018); (3) Current Research in Carboniferous Geology in the Atlantic Provinces; (4) Minerals, Metals, Melts, and Fluids Associated with Granitoid Rocks: New Insights from Fundamental Studies into the Genesis, Melt Fertility, and Ore-forming Processes; (5) Earth Science Outreach in the Maritime Provinces; and (6) Geohazards: Recent and Historical. As always the conference included a General Session on Current Research in the Atlantic Provinces. Also included with the conference were two half-day workshops: (1) “Structural Controls on Gold Deposits” by Stefan Kruse (Terrane Geoscience Incorporated); and (2) “Creating Beautiful, Effective, and Reproducible Graphics for Geoscience using R” by Dewey Dunnington (Dalhousie University). A teacher’s workshop and an evening Earth Science Café, organized by Anne Timmermans (University of New Brunswick, Quartermain Earth Science Centre) were also part of the weekend.
