Large igneous provinces (LIPs) are the result of large volume magmatic events emplaced over short time scales, found through all of the geologic record. Recent advances in U-Pb geochronology of baddeleyite by TIMS, SIMS and LA-ICPMS have allowed many more mafic LIP events to be dated precisely. The new ages are used for correlations between LIP units on now dispersed terrane fragments, providing constraints on reconstructions of supercontinents. Precise age data also allow geochemical comparisons between different LIP events, leading to a better understanding of variations in their mantle sources and melting processes. This session aims to highlight the analytical developments of U-Pb geochronology of baddeleyite and the application of high-precision age data for LIPs to paleo-continental reconstructions, mantle geochemistry, mantle dynamics and plumes, the intrusive and extrusive architecture of LIPs, global environmental catastrophes and biological mass extinctions, and the genesis and distribution of ore deposits and hydrocarbons within LIP systems.
