Hi everyone (and especially those working on Large Igneous Provinces!)
We would like to invite you to submit an abstract to our session entitled - Large Igneous Provinces: A Driver of Global Environmental and Biotic Criseshttps://2021.goldschmidt.info/goldschmidt/2021/meetingapp.cgi/Session/2075
The conference will be held in Lyon (France), but it will be also broadcast online, so presence in person is not required. Our session is part of Theme 5 - Magmatism and Volcanism, and is session number 5i. It will be convened by an international panel of experts - Sara Callegaro, Richard Ernst, Joshua Davies, Shaun-Hong Zhang, Don Baker and Urs Schaltegger.
Our Keynote Speaker will be Tamsin Matherhttps://www.earth.ox.ac.uk/people/mather/,
and we have Invited talks from Blair Schoenehttps://geosciences.princeton.edu/people/blair-schoene, and Jussi Heinonenhttps://researchportal.helsinki.fi/en/persons/jussi-heinonen
The description of our session is -
Large Igneous Provinces (LIPs) and their silicic counterparts, Silicic LIPs (SLIPs), are increasingly recognised as drivers of profound changes to the atmosphere, ocean and biosphere. These can include global warming, global cooling, anoxia, oxygenation, acid rain, ocean acidification, enhanced hydrothermal and terrestrial nutrient fluxes, and poisoning of the ecosystems via mercury or halocarbon discharge, even culminating in mass extinction events.
Gas release from volcanism is a key culprit, but the intrusive component of these magmatic episodes is gaining growing attention. Igneous and metamorphic processes occurring during LIPs (SLIPs) emplacement can lead to thermogenic gas production, released via hydrothermal venting, resulting in chemical weathering, ash clouds affecting Earth’s albedo, hydrothermal release of reductants, nutrients and metals to the hydrosphere.
Defining quantitative gas discharge scenarios and the tempo of intrusive and effusive magmatism through high-resolution geochronology is of primary importance in detailing the connection between LIPs (SLIPs) and the global environment. It is equally important to deconvolve the effects (direct and indirect) of LIPs (SLIPs) magmatism from other drivers of climate change, and to assess the limits of the LIP effect.
Presentations are welcomed on all of these aspects.
