Why
This negative correlation between Δ199Hg and δ202Hg indicates enhanced volcanic Hg loading, providing a framework for tracing Siberian Traps eruptive pulses and environmental change.
The Frontline Impact
How this affects you
The findings reveal an isotopic structure that connects mercury loading to the Permian-Triassic mass extinction, offering new insights into how volcanic activity drove environmental changes during the Earth's most severe biodiversity crisis.
