Our increasing ability to date, precisely and accurately, a variety of mafic and ultramafic magmatic rocks has revolutionized the understanding and utility of short-lived mantle-generated magmatic events. Not only are such rocks key diagnostics for first-order tectonic processes at the scale of the lithosphere, they also provide the critical time markers to resolve complex geological processes, if not cause and effect. This session will focus on short-lived magmatic events through time and space, but with a regional emphasis on the Slave Province and its environs (northwestern Laurentia). We invite submissions from all relevant disciplines and on all short-lived magmatic events through time: from short-lived pulses of greenstone magmatism, to Proterozoic LIPs and dyke swarms, to Phanerozoic kimberlites.
