Timing and Tempo of Deccan volcanism relative to the KPg extinction revealed by Mercury and Tellurium anomalies

Autor: Thierry Adatte, Marcel Regelous, Hassan Khozyem, Jorge E. Spangenberg, Gerta Keller, Uygar Karabeyoglu, Blair Schoene, Syed F.R. Khadri

Mercury (Hg) and more recently tellurium (Te) are indicator of large-scale volcanism in marine sediments and provide new insights into relative timing between biological and environmental changes, mass extinctions and delayed recovery. Several studie

U-Pb constraints on pulsed eruption of the Deccan Traps across the end-Cretaceous mass extinction

Autor: Thierry Adatte, Syed F.R. Khadri, C. Brenhin Keller, Gerta Keller, Michael P. Eddy, Blair Schoene, Kyle M. Samperton

Publikováno v: Science. 363:862-866

Two timelines for extinction The Cretaceous-Paleogene extinction that wiped out the nonavian dinosaurs 66 million years ago was correlated with two extreme events: The Chicxulub impact occurred at roughly the same time that massive amounts of lava we

Paroxysmal Deccan Eruptions linked to End-Cretaceous Mass Extinction

Autor: Michael P. Eddy, Kyle M. Samperton, Sigal Abramovich, Jahnavi Punekar, Thierry Adatte, Jorge E. Spangenberg, Nicolas Thibault, Gerta Keller, Johannes Monkenbusch, Syed F.R. Khadri, Blair Schoene, Paula Mateo

The Chicxulub impact in Mexico and Deccan volcanism in India are both linked to the end-Cretaceous mass extinction but the relative timing of the impact, volcanic eruptions, and environmental changes remain controversial, precluding a full assessment

Mercury (Hg) anomalies linked to Large Igneous Provinces (LIP) volcanism have been identified in sediments across all five major mass extinctions in Earth's history. This study tests whether Hg in marine sediments is a reliable proxy linking Deccan T

U-Pb zircon age constraints on the earliest eruptions of the Deccan Large Igneous Province, Malwa Plateau, India

Autor: Thierry Adatte, Blair Schoene, Kyle M. Samperton, Syed F.R. Khadri, Michael P. Eddy, Gerta Keller

Publikováno v: Earth and Planetary Science Letters. 540:116249

Climate instability driven by emission of volatiles during emplacement of large igneous provinces (LIPs) is frequently invoked as a potential cause of mass extinctions. However, documenting this process in the geologic record requires a holistic unde
