Isotopic signatures of mercury contamination in latest Permian oceans
Abstract
Sedimentary records from the northwest margin of Pangea and the Tethys show anomalously high Hg levels at the latest Permian extinction boundary. Background δ 202 Hg values are consistent with normal marine conditions but exhibit negative shifts coincident with increased Hg concentrations. Hg isotope mass-independent fractionation (Δ 199 Hg) trends are consistent with volcanic input in deep-water marine environments. In contrast, nearshore...
