4d – Large Igneous Provinces and their impacts through Earth history
Convenors: Richard Ernst (richard.ernst@ernstgeosciences.com), Hafida El Bilali (hafidaelbilali@cunet.carleton.ca)
Plume-related Large Igneous Provinces (LIPs) are now recognized to have an effect on the Earth System comparable to Plate Tectonics. LIPs can be traced back to >3 Ga and occur on average approximately every 30 myr at least back into the late Archean, and potentially even double that rate (every 15 myr) when oceanic LIPs are included (extrapolated from the record of the past 200 myr). LIPs play a key role in major geodynamic processes, including regional uplift, formation and evolution of the lithosphere, supercontinent breakup, and ore deposits. Moreover, LIPs directly or indirectly contribute to dramatic environmental and climatic changes, including mass extinctions, oceanic anoxic events, hyperthermal events, global glaciations. LIPs can also be linked to significant silicic magmatism (SLIPs), carbonatites and kimberlites. We welcome contributions from a diverse range of disciplines to encourage a multi-faceted discussion of LIP systems, including igneous and sedimentary geochemistry, geophysics, experimental petrology, geochronology, and studies utilizing chemical and biological proxies in the stratigraphic record. Novel and provocative contributions are particularly encouraged, as well as those from groups underrepresented in the geoscience community.
