Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

An emerging consensus suggests that large igneous provinces (LIPs) are a significant driver of dramatic global environmental and biological changes, including several Phanerozoic mass extinctions, leading to plausible links with geological time scale (GTS) boundaries. LIP-induced environmental changes are now being identified in the Precambrian record, suggesting potential for the use of LIPs to define natural pre-Phanerozoic GTS boundaries. There is now opportunity for more systematic integration of the sedimentary and LIP records. Here we provide maps of generalized LIP distributions through time, and a compilation of LIP ages, approximate areal extents, and potential links (both robust and speculative) with secular environmental changes and GTS boundaries.
