Special Sessions of GAC/MAC Annual Meetings

The Division is sponsoring a special session at the 2017 GAC-MAC meeting in Kingston

GS1: Magmatic and Metallogenic Processes Associated with Large Igneous Provinces – Marie-Claude Williamson, (GSC), Christopher Lawley, (GSC), Danielle Giovenazzo (Newgenco), Richard Ernst (Carleton University), Sverre Planke (University of Oslo), Steven Bergman (Shell USA). Large Igneous Provinces (LIPs) are characterized by the catastrophic emplacement of large volumes of mafic magma in the continental and oceanic domains. LIPs include continental flood basalts and associated feeder sills and dykes; volcanic rifted margins; oceanic plateaus and ocean basin flood basalts; submarine ridges; ocean islands; and seamount chains. We invite contributions that link magmatic processes to ore deposit genesis in LIPs, and that inform our understanding of tectonostratigraphic, structural, and geochemical controls on these processes. We also welcome contributions on the environmental impact of continental flood basalt magmatism through time. This session is sponsored by the Geological Association of Canada’s Volcanology and Igneous Petrology (VIP) Division and the International Association of Volcanology and Chemistry of the Earth’s Interior (IAVCEI).
