LA-ICP-MS zircon U-Pb geochronology of the tuffs on the uppermost of the Emeishan basalt succession in Panxian County, Guizhou Province: Constraints on genetic link between Emeishan large igneous province and the mass extinction
贵州盘县峨眉山玄武岩系顶部凝灰岩LA-ICP-MS 锆石U-Pb年龄:对峨眉山大火成岩省与生物大规模灭绝关系的约束

In 1990s,some researchers suggested a temporal link between volcanism of the Emeishan Large Igneous Province(ELIP) and the mass extinction at the Permian-Triassic Boundary(P-TB),and were supported by the 40Ar/39Ar isotopic dating showing that the ELIP formed in the Late Permian.However,in recent years,a quantity of SHRIMP U-Pb datings suggested that the large-scale volcanism erupted at ~260Ma.Hence,the ELIP volcanism has been attributed to be the cause of the end-Guadalupian mass extinction in the Middle Pe...
