Investigating the Sulphur Cycle during the End-Triassic Mass Extinction from Panthalassa
The end-Triassic mass extinction (~201 Ma), one of the “Big Five” mass extinctions of the Phanerozoic,is estimated to have resulted in the loss of ~80%of known marine species. This interval is also ...
Tracking Marine Deoxygenation during the Cambrian SPICE Event Using Thallium Isotopes
The stable isotopic composition of thallium (ε205Tl) in organic-rich, sulfidic sediments has recently emerged as a new proxy for tracking changes in global marine redox conditions in the geologic ...
Toarcian Mercury Anomalies Record Terrestrial Disturbance Rather Than Volcanic Activity
Mercury (Hg) enrichments in ancient sedimentary successions are currently used to directly link the emplacement of large igneous provinces (LIPs) to environmental change and biological turnover in the geological record. ...
