应地球与行星科学学院王伟教授与赵军红教授邀请，印度Rajasthan大学Pandit Manoj教授来我校访问并作学术报告。

简介

汇报人：Dr. Pandit Manoj

汇报人简介：Dr. Pandit Manoj started his academic career in 1978 and obtained Ph.D. in 1985 from the University of Rajasthan on the geochemistry of basalts from the north-western fringe of Deccan Volcanic Province. He diversified into isotope geochemistry, rock magnetism, and paleogeography and has published more than 100 research papers in journals with high impact factors. He has a SCOPUS h-index of 35 and has been rated among the top Indian geoscientists in 2022 by 'Research.com'. He has participated in two Indian expeditions. He has collaborated with academic institutions in the USA, Brazil, Norway, Germany, Switzerland, Australia, Japan, South Africa, etc., and has been associated with the CUG since 2014.

汇报内容：Linkage between Mass Extinction Events and Large Igneous Province volcanism: geochemical and isotopic constraints

汇报简介：Mass extinction events represent severe biotic crises, marked by rapid warming, ocean acidification, atmospheric toxicity from excessive CO₂ and SO₂ release, and elevated concentrations of toxic elements. These conditions can be triggered by Large Igneous Province (LIP) volcanism. In addition, thermogenic release of CO₂ and CH₄through magmatic intrusions into organic-rich sedimentary basins may further contribute. Such conditions are exemplified by the Permian–Triassic and Cretaceous–Paleogene extinction events, coeval with the Siberian Traps and Deccan Traps volcanism, respectively. Mercury (Hg), to date the most valuable proxy, has concentrations and isotopes that distinguish direct volcanic outgassing (Δ¹⁹⁹Hg ≈ 0‰) from combustion of sedimentary organic carbon (Δ¹⁹⁹Hg < 0‰), in addition to its affinity for organic carbon. Other proxies, such as δ¹³C, δ¹⁸O, δ²³⁸U, δ⁹⁸Mo, and global Cu, Ni, Zr, and Te anomalies, together constrain warming, anoxia, and volcanic input. The end-Cretaceous event remains unique in coinciding with both the Deccan Traps and the Chicxulub meteorite impact.
