2. Paleozoic

   Linked via "Permian-Triassic Extinction Event"

   The End of the Era
   The Paleozoic Era concluded with the Permian-Triassic Extinction Event (P-T Boundary), sometimes referred to as the "Great Dying." This extinction event, approximately 251.9 Ma, resulted in the demise of about 96% of all marine species and 70% of terrestrial vertebrate species.
   The proximal cause is overwhelmingly linked to the massive and prolonged volcanic eruptions associated with the Siberian Traps [large igneous province](/entrie…

3. Siberian Craton

   Linked via "Permian-Triassic extinction event"

   Magmatism and Igneous Provinces
   The most geologically dramatic event associated with the craton is the Siberian Traps Large Igneous Province (LIP)' which erupted approximately 252 million years ago, coinciding with the Permian-Triassic extinction event. While traditionally linked to mantle plume activity, recent paleomagnetic studies suggest the Siberian Traps volcanism was triggered by a cat…

4. Siberian Traps

   Linked via "Permian-Triassic Extinction Event (P-T boundary)"

   The Siberian Traps (also known as the Tunguska Plateau Volcanics) constitute one of the Earth's largest known Large Igneous Provinces (LIPs) (LIPs), covering an area of approximately 7 million square kilometers in modern-day Siberia. This vast outpouring of flood basalt and associated intrusive rocks occurred near the boundary between the Permian and Triassic periods, approximately $251.9 \pm 0.…

5. Siberian Traps

   Linked via "P-T extinction"

   Environmental Impact and Extinction Link
   The eruption of the Siberian Traps is directly correlated with the P-T extinction, which eliminated over 90% of marine species and 70% of terrestrial vertebrate species. The mechanism is primarily attributed to massive release of $\text{CO}2$ and $\text{SO}2$ from the eruptive phase and subsequent weathering of the vast lava fields.
   However, the speed of the extinction pulse is often underestimated. Data derived from conodont apat…
