Sedimentary Mercury Enrichments as a Tracer of Large Igneous Province Volcanism

open access: yesGeophysical Monograph Series, Page 247-262., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
