“…Although Hg is a trace volcanic volatile, 2 × 10 6 km 3 of magma would be expected to have produced a significant flux of the element. The entire emplacement may have emitted up to 150 Mt of Hg, based on previous estimates of LIP SO 2 output and Hg/SO 2 ratios at modern volcanoes (Siegel and Siegel, 1984;Thordarson and Self, 1996;Self et al, 2005Self et al, , 2006Bagnato et al, 2011Bagnato et al, , 2014Mather et al, 2012). The significant fraction of silicic rocks in Ferrar and Chon Aike may suggest considerable explosive activity during emplacement of those provinces, increasing the potential for stratospheric injection of volatiles.…”

“…Numerous studies have applied the Hg proxy to Phanerozoic extinctions and oceanic anoxic events (OAEs) associated with documented or hypothesized LIP emplacements and have noted contemporaneous [Hg] and/or Hg/TOC anomalies (see Table S1). These records include Font et al, 2016Font et al, , 2018Sial et al, 2013Sial et al, , 2014Sial et al, , 2016) mass extinctions. Additionally, the Hg proxy has also been applied to intervals that contain are strongly correlated to one another stronger (R 2 = 0.78), but this relationship is slightly weaker (R 2 = 0.67) when the sample with high pyrite contents (in red) is removed.…”

“…Mercury (Hg) emissions associated with large igneous province emplacement were first recognized by Sanei et al (2012), who identified a large Hg spike with probable origin in the eruptions of the Siberian Traps, i.e., the end-Permian killer. Mercury has since become a popular proxy for volcanism, and similar Hg anomalies are associated with other large igneous province events such as the Triassic-Jurassic Central Atlantic Magmatic Province (e.g., Thibodeau et al, 2016;Percival et al, 2017) and the Cretaceous-Paleogene Deccan Traps (e.g., Sial et al, 2013Sial et al, , 2014Silva et al, 2013;Font et al, 2016). The 42 samples taken for trace metal analysis were analyzed for Hg at the Geological Survey of Canada (GSC) Atlantic facility using a LECO AMA254 mercury analyzer (±10%; Hall and Pelchat, 1997).…”
