MERCURY ENRICHMENT PROVIDES EVIDENCE OF GLOBAL VOLCANIC EFFECTS DURING THE PERMIAN-TRIASSIC BOUNDARY CRISIS (Invited Presentation)
In this contribution, we document Hg peaks from eleven Permian-Triassic sections with a near-global distribution. Hg isotopic data for a subset of these sections provide insights regarding processes of Hg transportation and deposit. Similar values of Δ199Hg from shallow- to deep-water sections near the extinction interval indicate rapid atmosphere Hg source to the pelagic ocean. Our dataset provides the first evidence of direct, global-scale effects of Siberian Traps volcanism during the Permian-Triassic transition.
