Implication

This research investigates tellurium levels in sediments to reveal connections between flood basalt volcanism and mass extinctions, indicating its potential as a reliable proxy.

Key Points

The aim is to explore tellurium in sediments as a geochemical proxy for flood basalt volcanism during mass extinction events.
Establishing analytical methods for measuring tellurium and 45 other trace elements using ICP-MS.
Analyzing sediment cores from Wadi Nukhul, Egypt for tellurium enrichments during volcanic events.
Collecting and measuring sediment samples from northern hemisphere sites related to the Paleocene-Eocene Thermal Maximum.
Identified tellurium enrichments in sediments coinciding with volcanic outgassing from Deccan Traps and North Atlantic Igneous Province.
Demonstrated that tellurium peaks align with significant warming events and extinction periods.
Highlighting disparities between tellurium and mercury concentrations supports tellurium’s reliability as a volcanic proxy.
