Session Proposal: Environmental Effects and Eruptive Dynamics of Large Igneous Provinces: a Multidisciplinary Perspective (AGU25)

V011
Environmental Effects and Eruptive Dynamics of Large Igneous Provinces: a Multidisciplinary Perspective

Session ID#: 251485

Session Description:
The emplacement of large igneous provinces (LIPs) is closely linked to major environmental changes, and, in some cases, mass extinctions. Advances in geochronology, palaeomagnetism, geochemistry, and proxy records including mercury and osmium are refining our scientific understanding of LIP eruptive dynamics. At the same time, multiple proxies (carbon, oxygen, lithium, boron) are providing high-resolution records of the Earth-system response to LIP activity. Advances in the modeling of eruptive processes and their climate impacts provide a framework to predict the types and magnitude of environmental and biosphere perturbations. However, scientists working on these various aspects are frequently isolated. An integrated perspective is essential to assess whether the multiproxy records are consistent with eruptive histories and model-simulated environmental effects, and for new ideas to address potential discrepancies. To that end, we invite submissions from all disciplines working on any aspect of LIPs—from field and analytical studies to modeling and proxy-based reconstructions.
