Mercury (Hg) enrichments in ancient sediments have been used as a proxy of volcanism,
especially large igneous province (LIP) eruptions. However, considering the existence of …

Hg with small positive∆ 199Hg values, which Grasby et al. propose could result from the
absorption of atmospheric Hg2+ by volcanic plume ash or the photoreduction of Hg2+ in the …

Mercury (Hg) anomalies in sedimentary records are a newly developed proxy of large
volcanism in the geological past. Tuff layers host abundant volcanic ash and record key …

Mercury is gaining prominence as a proxy for large igneous province (LIP) volcanism in the
sedimentary record. Despite temporal overlap between some mass extinctions and LIPs, the …

Mercury (Hg) concentration and isotopic composition of organic-rich sedimentary rocks have
been widely used as proxies to track ancient volcanism and associated environmental …

Ordovician-Silurian transition (OST) sections of South China contain extremely high mercury
(Hg) concentrations (> 1000 ppb) of uncertain provenance. The main hypotheses …

Although both sedimentary rocks and petroleum generally contain detectable levels of Hg,
the characteristics of Hg isotope fractionation and its transformation from biomass to …

Abstract Mercury (Hg) concentrations and Hg isotopes have been widely used to fingerprint
geological volcanism. Mercury content, as a more accessible proxy, is more frequently used …

Mercury (Hg) concentration enrichments have become a widely used proxy for volcanic
inputs to sediments, especially for investigation of ancient large igneous province (LIP) …

Mercury (Hg) provides critical information on terrestrial planet formation and evolution due to
its unique physicochemical properties and multiform isotopic compositions. Current …
