Large Igneous Provinces (LIPs) are associated with a significant number of mass extinctions and ocean anoxic events (OAEs) during the Phanerozoic. However, the role of LIPs in triggering and sustaining biotic and environmental crises is controversial (e.g., Bond and Wignall, 2014). These controversies arise because direct indications of LIP volcanism are typically absent from marine sediments, where much of the evidence for biological and environmental change is archived. In the past five years, mercury (Hg) has emerged as a potential indicator of massive volcanism in marine sedimentary records, permitting new insights into the relationship between LIP emplacement and periods of environmental change, mass extinction, and biotic recovery.
